About This Plan
This plan has been prepared using Appendix B of Guidelines for Preparing
Quality Assurance Project Plans for Environmental Studies, a publication of
the Washington State Department of Ecology (DOE, 2004), and it is intended
to be used as the quality assurance project plan (QAPP) for the groundwater
monitoring program that this plan describes. The DOE guidelines follow a systematic planning process described by the U.S. Environmental Protection
Agency (EPA).
This Plan only includes the pertinent elements specified in DOE’s guidelines,
which are designed to address a range of environmental studies. It does not include the rigorous, detailed elements required for contamination studies because we propose monitoring only constituents that occur naturally, at measurable concentrations, under both unimpacted and impacted conditions.
2
Distribution
Twenty-five copies of this monitoring plan have been distributed to the members of the WRIA 16 Planning Unit.

Background
The Skokomish-Dosewallips Basin, WRIA 16, is located on the Olympic Peninsula on the west side of Hood Canal (Figure 1). The southern part of WRIA
16 lies in Mason County and the northern part lies in Jefferson County. The
physiography ranges from the snow-capped mountains in the western part of
WRIA 16 to the flatlands of the Skokomish River Valley in the southeastern
part and to the hills and river valleys along the eastern shore of Hood Canal.
The WRIA 16 Planning Area includes the south shore of Hood Canal, which is
WRIA 14b. This is the portion of WRIA 14 (Kennedy / Goldsborough) that
drains north into the lower Hood Canal.
The principal drainages in WRIA 16 are the Dosewallips, Duckabush, Hamma
Hamma, and the Skokomish Rivers. Many smaller streams discharge into
Hood Canal.

Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
3.1
Hydrogeology
In general, the hydrogeology of the area is characterized by glacial deposits
and basalt. Glacial deposits comprise permeable outwash, low-permeability
till, fluvially reworked glacial deposits, and low-permeability glaciolacustrine
silt and clay. Wells are completed in gravel units within the unconsolidated deposits or in fractured basalts. Uplands may be covered with a thin veneer of
glacial deposits overlying basalt. River valleys have a relatively thick sequence
of glacial deposits beneath alluvial deposits.
During 2002, the Planning Unit completed a draft Phase 2 Level 1 Technical
Assessment which describes what is known about water issues. A key finding
concludes that although much less than 1 percent of the total amount of available water is actually used, the watershed still faces serious availability problems during the low-flow summer months.
Development in the basin is primarily concentrated along the shorelines of
Hood Canal and Lake Cushman. Water supplies are needed for future development in the Brinnon area, most notably the Black Point area. Other “growth
areas” include Union, Hoodsport, and Lilliwaup. Some wells near the shore
have experienced seawater intrusion. A few are located inland in more remote
parts of the basin; access to these wells may be difficult or require lengthy
driving time.
3.2
Previous Work
Most of the water quality information available for the WRIA 16 Planning
Area is for surface water (streams and marine areas). For streams, concerns include nutrients (primarily nitrate), pH, and coliform. For marine waters, low
dissolved oxygen is the primary concern. Very little groundwater quality data
has been collected for wells throughout the WRIA 16 Planning Area. Some
data indicate that chloride is a constituent of concern in a few wells and may be
a result of seawater intrusion. Hydrogeologic Study of the Lower Dosewallips /
Brinnon Area reports that the chloride source is uncertain. The report recommends additional sampling to identify whether the chloride originates from
seawater intrusion or from connate groundwater.
A water supply and groundwater impact analysis was prepared as part of the
Draft Environmental Impact Statement prepared for the Pleasant Harbor Marina and Golf Resort. This analysis includes subsurface sections through the
Black Point peninsula in the Brinnon area (Subsurface Group, 2008).
The U.S. Geological Survey (USGS) has monitored shallow groundwater quality for nutrients along the South Shore of Hood Canal (Turney and Simonds,
2006; Simonds et al, 2008). Most of the USGS samples were collected from
2
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
temporaiy shallow piezometers that were installed for the study. However, neither the USGS nor any other agency has monitored ambient groundwater levels
or water quality in the WR.IA 16 Planning Area; consequently, we have no reasonable means to determine whether foture groundwater development will
cause unacceptable impacts on sti·eamflow, aquifer levels, an d water quality.

Monitoring Program Description
4.1
Objectives
The goal of this Plan is to provide a framework for implementing an ambient
monitoring program in WR.IA 16 Planning Area. Designed to addresses water
levels an d groundwater quality, this program uses a wide anay of wells to
cover a large geographic expanse that includes areas where foture development
is expected to occur. The monitoring data will not only serve as a basis for
characterizing the regional hydrogeology, but it will also help fill gaps that
were identified during eai·lier studies. Most impo1i antly, it will provide a basis
for predicting the impacts of foture proposed groundwater development an d
provide data for early detection of water quality and water quantity problems.
Planners can then make decisions that sustain adequate sh'eamflow, aquifer
levels, an d water quality. This plan specifies procedures an d protocols for
achieving several key objectives, as noted below.
Objective
Represent the range of hydrogeologic
conditions in the basin
Identify seasonal w ater level trends
Identify trends in concentrations of key
constituents
Provide data for evaluating possible
seawater intrusion
Collect data on a regular schedule from
private and water supply wells
Ensure greatest possible data accuracy
Approach
Select a set of monitoring wells in optimum locations
Monitor quarterly at selected w ells for at
least 2 years
Select an optimum suite of analytes for
reaular w ater samplina
Monitor chloride continuously at selected w ells
Develop cooperative relationships with
well owners that respect their time and
property
Collect samples and review lab results
using consistent protocols; maintain
data in a format consistent with DOE's

Data Sources
This Plan uses information from many sources:
4.3
•
DOE well log database (1,712 wells within the WRIA 16 Planning Area)
•
Washington State Department of Health (DOH) database (116 Group A
wells and 137 Group B wells in the WRIA 16 Planning Area, in the form
of shapefiles)
•
Brinnon area hydrogeologic study (Aspect, 2005)
•
USGS nitrate study in South Hood Canal (Simonds et al, 2008)
•
Mason County PUD#1 wells
Method
4.3.1
Database
Well data was imported into an Access database after establishing project coordinates using GIS methods. Logs for the deepest wells in each section were
printed, summarized, and entered into Access. The database was then integrated with ViewLog, which allowed us to map the wells, create a set of crosssections, and view the wells and well logs in a three-dimensional system.
4.3.2
Well Selection
Wells were selected based on location and depth to represent groundwater
conditions throughout the WRIA 16 Planning Area. The data set includes shallow and deep wells, wells completed in the basalt and unconsolidated deposits,
wells located on uplands and lowland areas, wells located near the shore, and
inland wells. Our selection criteria also emphasized “growth areas”—Brinnon,
Black Point, Triton, Lilliwaup, Hoodsport, the Lower Skokomish River valley,
Union, and the Sunset Beach area—where future groundwater development is
likely. A few remote wells were also selected for background conditions. To be
selected for continuous monitoring, a well had to meet one of two criteria: It
must lie within a growth area that is subject to seawater intrusion or it must lie
within an area where groundwater decline is an issue.
In general, shallow wells near streams were not considered because these wells
are likely already being monitored under DOH’s GWI program (groundwater
under the influence of surface water) and these wells are not as pertinent to the
issue of future groundwater development.
In general, the majority of the population and areas of anticipated growth occurs near the Hood Canal coastline. For these cases, potential for seawater intrusion is an important concern due to proximity to marine waters of Hood Ca-
4
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
nal. Therefore, while domestic wells occur within a broader part of the WRIA
16 Planning Area, most of the recommended wells occur near the canal’s
coastline.
4.4
Implementing the Monitoring Program
The tasks required to implement the Plan are summarized below. These tasks
would be conducted on a quarterly basis, unless stated otherwise. Detailed
monitoring procedures are given in Section 8, “Sampling & Measurement Procedures.”
For Startup:
•
Conduct a site visit to each well.
•
If it has not already been obtained, obtain a signed written agreement.
•
Locate well on a map using local streets or use a hand-held GPS unit to
identify spatial coordinates of the well. Update the land-surface and wellbottom elevation data in the database, using GPS elevation data or digital
elevation data with mapping software (GIS or ViewLog)
•
Confirm the ability to place a sounder down the well.
•
Identify and mark the measuring point on the well. Identify and describe
the sampling port.
•
Prepare a local map for each well and include any detailed descriptions
needed to describe clearly and concisely how to find and access the well,
the measuring point, and the sampling port.
•
Place the map in the field notebook.
For Quarterly Monitoring:
Step 1: Confirm the time and date of the site visit by telephone. If only water
level measurements will be made, request that the pump be shut off when you
arrive.
Step 2: Visit each well.
•
For wells with continuous monitoring, download data from the datalogger.
•
If applicable, collect a water sample from a spigot as close to the wellhead
as possible. Avoid sampling from garden hoses or from plumbing that receives water from a holding tank. Use the quality assurance protocols described in Section 8.2, “Collecting Water Samples.”
5
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
•
Shut the pump off, if necessary, and measure the depth to water. Keep
measuring until the water level stabilizes. Record this measurement using
the quality assurance protocols described in Section 8.3, “Measuring Water
Levels.”
Step 3: Store samples in an ice chest and bring them to the lab within the
shortest holding time of all the analytes. Alternatively, have the lab pick up the
samples.
Step 4: At the office, enter data into a spreadsheet or database.
Step 5: Review the quality control parameters to evaluate the data’s validity
and usability.
Step 6: Copy any continuous digital data to an Excel spreadsheet and update
the hydrograph for each well.
4.5
Duration of the Monitoring Program
The monitoring program should proceed according to this plan for at least two
years. After two years, the data should be evaluated to determine if the program should continued unchanged or be modified. The data should be reviewed to identify wells that could be eliminated from the program due to reduncy, wells that should be added due to new needs or information, and to
modify the analyte suite if needed. Similarly, water quality sampling frequency may be reduced if appropriate.
5
Organization, Schedule, & Budget
This section describes the project organization, schedule, and specific responsibilities. At this time, the Planning Unit has not identified who will conduct
and pay for the monitoring, or when the program would begin; therefore, this
Plan does not specify a start date or schedule. This section offers generic
guidelines but does not name individuals, institutions, or dates.
5.1
Organization
The Planning Unit will identify an individual within one of its participating
agencies (for example, Mason County) or hire a consultant to conduct the
monitoring. This individual(s) will answer to the Planning Unit and will be responsible for measuring water levels, collecting water quality samples, implementing quality control procedures, managing data, and reporting. We recom-
6
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
mend that the Planning Unit designate one of its members to directly manage
the individual who manages the work described above.
5.2
Schedule
This monitoring plan describes a quarterly schedule for sampling, data review,
and data management activities. The final schedule will be determined by the
Planning Unit based on the available budget and/or other criteria. Quarterly
monitoring will be scheduled to optimize the recording of maximum seasonal
change.
5.3
Budget
At the request of the WRIA 16 Planning Unit, the budget for the monitoring
program has been prepared in three tiers.
•
Tier 1, the least expensive, attempts to minimize cost while maximizing
data collection.
•
Tier 3, the most expensive, is designed to obtain the best data for understanding ambient groundwater quality and quantity conditions, for tracking
trends in water level and conductivity at selected wells, and for documenting spatial variability.
•
Tier 2 offers an alternative that lies between the bare minimum of Tier 1
and the completeness of Tier 3.
Table 2 summarizes the tasks and costs to implement the monitoring program
for each tier. Startup costs are separate from annual costs for quarterly monitoring. The budgets allow the Planning Unit to modify the number of wells that
would be subject to quarterly water level measurements, water quality sampling, and continuous monitoring. In this way, the details of the monitoring
program can be adjusted to meet constraints based on budget or specific information needs.
Table 2 shows Tier 1 has 35 wells monitored for water level and 25 wells
monitored for water quality, while Tier 3 has 50 and 40 wells, respectively.
Because of the expense of laboratory analyses, fewer wells are monitored for
water quality than water level to reduce costs. The exact number of wells
monitored for water level and water quality can be modified as needed. More
wells would provide a greater range of spatial variability. Fewer wells, such as
30, would still provide a useful set of data. Fewer than 25 to 30 wells would
likely not provide an adequate representation of the hydrogeologic conditions.
7
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
Startup costs reflect equipment and field hours needed to confirm location and
well access, identify the sampling port, and the office work needed to prepare
the field map and data sheets for each site. Annual costs reflect the field and
office hours needed to collect and manage the data and analytical laboratory
costs. Equipment costs include sales tax of 8.5% but do not include any handling fees.
Cost estimates were obtained from four labs in the area that are accredited with
DOE. Costs are shown on Table 2 and assume the cost for the low end of the
cost range. Analytical laboratory costs could increase by as much as several
thousand dollars per year if a more expensive laboratory is used. Laboratory
cost estimates do not include sales tax or handling fees. No sample transport
costs are included in the budget. Transport costs would need to be included if a
non-local lab is used.
Field and office hours assume a rate of $120/hr.
Additional budget should be considered to pay for the analytical laboratory
costs for the Skokomish Indian Tribe water supply wells so that they use the
same analytical methods and meet the same data review criteria as the data collected specifically for this project. These costs are included in the budget given
in Table 2. Therefore, for each tier, the number of wells associated with laboratory costs is increased by two more than the number of wells sampled.
6
Data Quality Objectives
The data collected under this plan will be useful for guiding future groundwater development but not for decision processes that outline critical, specific actions depending on the analytical results. Therefore, this section presents
measurement quality objectives (MQOs), which describe how good the data
must be to meet the objectives of the project. It does not include decision quality objectives (DQOs). Data that meet the objectives will be considered accurate and valid. Several types of errors will affect the quality of the data for this
monitoring program:
•
•
•
•
•
•
Errors in water level measurement
Errors in sampling (during collection of water samples)
Analyst errors during the measurement of field parameters
Equipment errors during the measurement of field parameters
Analyst and equipment errors during laboratory analysis of water samples
Data-entry errors during the data management process
The detailed sampling and measurement procedures described in Section 8,
“Sampling & Measurement Procedures,” address potential errors from sources
8
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
that are not related to labs or equipment. The MQOs described below, on the
other hand, are designed to identify whether the results reflect lab- or equipment-related errors; Section 9, “Quality Control,” offers procedures for reducing such errors.
In general, MQOs are used to evaluate quality control (QC) results; if the QC
results meet the MQOs, they are considered valid and it is inferred that the
sample results are also valid. However, the ion-balance error, which can be
calculated, provides a direct means to evaluate whether the major ion data is
valid for each sample. This section addresses the MQOs and ion balance separately.
6.1
MQOs
The MQOs are based on quality assurance criteria for method blanks, analytical duplicates, matrix spikes, and standard checking for each batch of samples.
MQOs are given in Table 3. While the quality control procedures (Section 10)
describe the required tests and their frequency, the control criteria establish the
acceptable results from these tests.
To evaluate bias, results for matrix spikes will be reviewed. To evaluate precision, results for analytical duplicates will be reviewed (DOE, 2004).
6.2
Ion-Balance Error
In water the charge of the anions (which is negative) must equal the charge of
the cations (which is positive). The accuracy of major dissolved-constituent
values can be checked using a cation-anion balance (Hem, 1985). The ionbalance error will be calculated for annual samples that have been analyzed for
a complete suite of routine ions (sodium, potassium, magnesium, calcium,
chloride, sulfate, carbonate and bicarbonate). It should not exceed 10 percent.
6.3
Completeness
Completeness is a measure of the amount of valid data needed to be obtained
from the measurement system. The goal for this monitoring program is to sample at least 95% of the wells identified to be included. Ideally, 100% of the
wells identified for the program would be monitored each quarter.
9
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
6.4
Comparability
Comparability is the ability to compare the data with data from other studies.
Comparability is ensured by selecting and documenting standardized procedures for sampling and analysis. This plan strives to use consistent field and
analytical methods over the course of the groundwater monitoring program.
7
Sampling Process Overview
Wells will be sampled quarterly. If access allows, water levels will be measured in all wells, and water samples will be collected at selected wells. Several
parameters will be measured in the field at the time of sampling—specific
conductivity, pH, temperature, and dissolved oxygen (DO). In addition to these
field parameters, water samples will be analyzed by a laboratory for chloride,
nitrate, dissolved oxygen, and total dissolved solids (TDS). Annually, samples
will be also be analyzed for sodium, potassium, calcium, magnesium, sulfate,
and alkalinity. Table 4 summarizes the recommended analyte list and schedule
for the monitoring program. This table may be modified at the request of the
Planning Unit based on budget constraints or other criteria. Once finalized, the
list should be incorporated into both this Plan and the field notebook.
Selected wells may be instrumented with a datalogger and a sensor to record
frequent measurements of electrical conductivity and water level. Some wells
will be instrumented with a datalogger and sensor to record only water level in
wells where water level decline is the only significant concern. Recommended
data collection frequency should be about every half-hour. This would provide
sufficient data to identify tidal effects but not so much data that the data volume is unwieldy. Data from these wells will be downloaded quarterly, on the
same schedule as the other wells. Before setting the data collection frequency,
confirm that the datalogger memory can hold the number of records indicated
by the selected frequency. Manual water level measurements will be made at
each well before digital data are downloaded.
7.1
Recommended Monitoring Wells
Table 1 lists wells that should be considered for the monitoring program. A final set of monitoring wells will be selected from this table based not only on
budget constraints but also on the feasibility of negotiating an access agreement and measuring water levels using a sounder. Tier 1 would include the
minimum number of wells and would provide good spatial distribution of
wells within the populated area of the WRAI 16 Planning Area. Tier 3 would
include a larger number of wells, would provide a good spatial distribution of
10
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
wells, but would monitor more wells in the highest growth areas and would
have more shallow deep pairs.
Wells in Table 1 are grouped by nearest town and listed in order from the
northern part of the WRIA 16 Planning Area at Seal Point to the southern part
at Union and then east along the south shore of Hood Canal toward Belfair.
Each well is assigned a priority number of 1, 2, or 3 for water level and water
quality monitoring. Due to costs, fewer wells will be monitored for water quality than for water leve1. A priority of “1” indicates that the well should be considered for Tier 1. Since Tier 3 is more comprehensive than Tier 1, all wells in
Tier 1 would be included in Tiers 2 and 3. A priority of more than “1” indicates that the well’s inclusion will depend on which tier the Planning Unit selects and how many wells can be monitored. Wells with a “Y” in the “Definite” column should definitely be considered in Tiers 1, 2, and 3; verbal
agreement to monitor has already been made with the well owner or operator
for these wells.
Figure 1 shows the well location for the wells included on Table 1. Wells designated as definite are indicated with a different symbol than the rest of the
wells. The well numbers shown on Figure 1 are given in Table 1. Figure 1 illustrates that in areas where many wells are available, like Hoodsport and Union, the list includes more wells than needed, to provide plenty of options in
case access is a problem. Similarly, in Ayock, Hamma Hamma, and west of
Forest Beach. More wells than needed are provided in Table 1 in case the well
is not accessible or permission from the well owner is not provided. Therefore,
there are more wells with a priority of 1 than would be included in a Tier 1
program. The final list should include at least one well in each of these areas
for Tier 1. The final list could also include a well that is not currently on Figure 1 if it is deemed important by the Planning Unit.
Table 1 summarizes hydrogeologic information, the reason for the well’s inclusion, the status of verbal approval from the owner, and contact information.
In some cases, we have not yet successfully contacted well owners and we
therefore recommend a site visit to obtain approval. Site visits should be conducted for each well that is selected for monitoring to confirm adequate access.
Well owners must sign a formal statement of agreement to monitor; Appendix
A contains sample agreements.
7.2
Parameters of Investigation
Field parameters—pH, specific conductivity, temperature, and dissolved oxygen (DO)—will be measured at wells sampled for water quality. Collected
samples will be sent to the analytical laboratory for analysis of pH, TDS, nitrate, chloride, and dissolved oxygen. Annually, the samples will also be analyzed for calcium, magnesium, potassium, sodium, sulfate, and total alkalinity.
11
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
If the pump has been shut down for more than a few hours, the pumping rate
will be estimated and the pumping duration prior to sampling will be recorded.
For consistency and comparability, all wells will be sampled within a 2-week
period during each quarterly sampling event.
7.3
Other Available Data
The Skokomish Tribe currently monitors groundwater beneath the Skokomish
Reservation from about nine shallow monitoring wells. In addition, supply
wells are monitored regularly for water quality. Although these wells will not
be part of the monitoring program, the Tribe will provide historical and future
monitoring data to the Planning Unit. These data should be included in the data
management aspect of the monitoring program so that data from the Skokomish River valley are included. Similar analytical methods should be used to
ensure comparability.
Mason County currently monitors two wells that are near to Webb Hill. Mason
County will continue to monitor these wells and provide the data to the project
manager of the monitoring program to be included in the data management
procedures. Mason County will conduct the quality assurance and quality control review of the data before providing the data to the project manager.

Sampling & Measurement Procedures
8.1
Measuring Water Levels
Step 1: Prepare
Before going out in the field, turn on the sounder and use the battery test to make sure it is working properly. Always carry spare
batteries for the sounder.
Step 2: Measure
Measure the water level. If possible, use the same sounder that
has been used for previous measurements. Turn the sounder on.
•
If the well has a sounder access tube, hold
the sounder tape between your thumb and
index finger and lower it into the tube until
the probe tip completes the circuit by
touching the water surface. You may need
12
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
to raise and lower the tape to find the surface. Read the measurement at the
top of the tube on the sounder tape.
•
If the well does not have a sounder access tube, lower the probe into the
well until it touches the water surface and completes the electrical circuit.
Be sure to lower it slowly and carefully to prevent the sounder from swinging and getting caught on something such as the riser pipe. Measure the
depth to water while holding the measuring tape at the top of the well casing or some other stationary location.
Take several measurements a few minutes apart to ensure that the water level
in the well is stable. Compare the measurement to the previous one to verify
that it makes sense. If not, measure again.
Step 3: Record
Record the date and time on the field data sheet for the well. Only record
measurements when water level stability is indicated. Record the final measurement as the depth to water.
Mark the spot on the casing (or other object) where you measured the water
level (for example, a particular location on the top of casing). Describe this location on the field data sheet and use your mark each time you measure that
well.
Step 4: Clean and decontaminate the sounder
The sounder will be cleaned as it is removed from the well, before being
wound onto the reel. The sounder tape will be wiped with a clean cloth using
either isopropyl alcohol or a weak bleach solution. To make a 0.5% solution
using standard household bleach (3.5%) use 1 part chlorine to 6 parts water.
The probe tip will be sprayed with the bleach solution before and after each
use. If at any time, after removing a sounder probe from a well, the probe
showns evidence of iron bacteria in the form of brown slime, with wire tape
and probe tip should be washed in soap to reomove the visible slime and then
rinsed or wiped down with alcohol or bleach solution.
8.2
Collecting Water Samples
Step 1: Purge
If the pump has been off for a while and you (or the owner) just turned it on for
sampling, pump the well until at least three borehole volumes have been
purged.
13
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
To verify that the well has effectively been purged, monitor pH, temperature,
and conductivity. When these parameters stabilize (successive measurements
change by less than 10 percent), you can assume that formation water has entered the well. Measure the three parameters at 5-minute intervals, or less, and
document times and values on the field data collection sheet, which should reside in the field notebook with previous sheets for the well.
See Section 8.3, “Measuring Water Quality ,” for details about equipment and
procedures. See Section 8.5, “Recordkeeping,” for information on calculating
borehole volumes. Section 9.1 “Quality Control, Field” provides guidelines
for obtaining bottles form the analytical lab.
Step 2: Sample
Collect the sample only after the field parameters stabilize—even if three borehole volumes have already been purged. Document the time of sampling.
•
Collect samples from a spigot as close to the wellhead as possible.
•
Avoid sampling from a garden hose or from a point after the water has
moved into a holding tank.
•
Place samples directly into bottles provided by the analytical laboratory
and cap them immediately.
•
Take care to prevent overflow in bottles that contain a preservative.
•
When holding the sample bottle, keep your hands away from the opening
to prevent contamination. Do not touch the open edge of the sample bottle
with the spigot or anything else.
Step 3: Label
Label the samples clearly with the well name, date, time, and your name or initials.
Step 4: Preserve
Keep samples in a cooler with ice at 4 degrees centigrade or less from the time
of collection until delivery to the lab.

Measuring Water Quality Parameters in the Field
8.3.1
Specific Conductivity, pH, and Temperature
Specific conductivity, pH, and temperature should be measured using a field
instrument purchased specifically for this project. We recommend the portable
and waterproof Hanna HI 98129, which is reliable, easy to use, and relatively
inexpensive. The instrument should be calibrated according to the manufac-
14
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
turer’s instructions at the beginning of each day. Clean the probe after each
measurement by spraying it with distilled water, which you can buy at grocery
stores. Be sure to purchase distilled water—not purified water, which contains
dissolved constituents.
8.3.2
Dissolved Oxygen
Use CHEMets®—self-filling ampoules for visual colorimetric analysis—to
measure DO. These easy-to-use kits (and refills) are available online at
www.chemetrics.com/visprods/Oxygen.htm. Be sure to purchase separate kits
to cover the ranges from 0–1 ppm and 1–12 ppm. One set of refills should always be available in the field.
To use the CHEMets, immerse the ampoule in the sample and snap the tip. The
correct volume is drawn in by vacuum, leaving a small, inert gas bubble. To
mix the sample and reagent, tilt the ampoule so the bubble travels from end to
end. In 2 minutes or less, compare the resulting color to the standards that
come with the kit to quantify the result. Test first using the 1–12 ppm kit. If
concentrations are less than 1 ppm, test again using the 0–1 ppm kit.
8.4
Continuous Monitoring
Water levels and/or conductivity can be monitored continuously using a downhole sensor and a datalogger. Electrical conductivity is of particular interest
because it can be used as an indicator of seawater intrusion. Work by USGS
indicates that conductivity can range widely within a single well over a relatively short period and that values can vary with the tide. Occasional single
measurements provide limited information about seawater intrusion. Therefore,
it is important to observe trends over a relatively long period. Continuous
monitoring for at least 1 month will indicate the general range in conductivity.
To optimize resources, a single transducer can be moved to different wells at
different times during the study. The monitoring results, however, may reveal
one or more wells that would be good candidates for a dedicated transducer;
likewise, they may also show that “sharing” a transducer is the best approach.
It is may be useful to monitor a single well for one quarter and then switch to a
different well for the next quarter. In this way, one conductivity sensor and
datalogger could be used to monitor several wells.
Step 1: Record a baseline measurement.
Before installing a sensor and datalogger, measure the water level with a
sounder. Record the time and water level on the field data sheet. This measurement will be used to calibrate the digital data.
15
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
Step 2: Install the equipment and set the measurement interval.
Install the datalogger and sensor according to manufacturers’ instructions. Include a copy of the calibration data sheet in the field notebook. After installation, set the reading frequency to every minute. Collect data for a few minutes
and then download the data to verify that the datalogger is recording and
downloading properly. Once you establish that the equipment is functioning
properly, set the data measurement interval to 30 minutes to record 48 measurements per day.
8.5
Recordkeeping
Maintain a field notebook, either bound or loose leaf, for the monitoring program. The notebook should feature a separate section divider labeled for each
well. Each divider should contain a field data collection sheet for water level
and water quality monitoring. Example field data collection sheets are included
in Appendix B.
The water level sheet should document the name of field technician, monitoring well, date, and time; water level measurements will be recorded for each
well so they can be compared.
The water quality sheet should document the flow rate, purge time, and date /
time of sampling for each sampling event. It should also include the well
depth, diameter, and borehole volume calculations. The well depth and diameter are typically available on the well log, which should be incorporated into
the field notebook.
8.5.1
Calculating Purge Volumes
Use the following equation to calculate three borehole volumes of water:
Purge time = (3 x borehole volume) / flow rate
Borehole volume = 3.1416(inner diameter of well) x (well depth – water depth)
8.5.2
Initiating the Chain of Custody
Fill out chain of custody (COC) forms and keep a copy in the notebook. The
COC forms must accompany the samples to the lab. Take care to ensure that
you are the only person to handle the samples until they are delivered to the
lab. Both you and the lab personnel will sign the form at the time of delivery.

Quality Control
9.1
Procedures
9.1.1
Field
The pH/conductivity meter should be calibrated each day using fresh standards. Calibration results should be recorded in the field notebook.
9.1.2
Laboratory
The selected laboratory will be accredited by DOE. The quality control procedures in this plan rely heavily on this lab’s quality assurance program (See
Section 6, “Data Quality Objectives”). Table 5 summarizes these procedures
and the frequency at which the lab must conduct them. In general, standards
are checked daily and other quality control measures such as method blanks,
analytical duplicates, matrix spikes, and matrix spike duplicates are performed
once per batch. A batch of samples comprises no more than a set number of
samples—most commonly, ten.
The lab includes the results of its quality control procedures with each quarterly report of analytical results for the samples submitted. This report should
be reviewed by a designated individual to verify that they meet the MQOs for
the monitoring program.
Samples collected for specific analyses may require a minimum volume, or the
bottle may require special treatment. To minimize errors related to insufficient
sample size or preservation, the lab should provide the bottles. The field sampler will contact the lab and request a bottle order for the number of wells being sampled and for any field duplicates that are to be collected. The lab will
provide the correct bottles, along with any required preservatives for the requested analytes. Table 6 summarizes the sample bottles, preservation, and
holding times for the analytes being considered for this project. Table 4 shows
the analytical methods and reporting limits that should be used for the program. These analytical methods are approved by DOE. Methods different from
those shown on Table 4 should be approved by the quality assurance officer at
DOE.
9.1.3
Ion-Balance Error
Ion-balance errors will be calculated for each sample with major ion analyses.
The calculation should be automated using software features in Access or Excel, whichever is used for data management, using the following formula:
Percent ion balance error = [(cations – anions)/(cations + anions)]x100
17
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
Cations and anions are expressed in concentration units of milliequivalents per
liter.
9.1.4
Compare Field and Laboratory Results for TDS and DO
Field and lab measurements of TDS and DO will be compared using the following equation:
Percent error for field parameter = [(Field-Lab)/Lab]x100
If the difference is less than 5 percent of the laboratory results, then the frequency of laboratory measurements may be considered to reduce long-term lab
costs.
The DO is measured in the field as an inexpensive, semi-quantitative method
to identify low, moderate, or high concentration of dissolved oxygen. Since
low DO in marine waters of Hood Canal is a concern, approximate concentration for DO in groundwater in the WRIA 16 Planning Area is useful to better
understand the role of groundwater with regards to the low DO in Hood Canal.
Field measurements for DO will be compared to laboratory results to identify
if the field method is reliable for long-term use in this study in lieu of more expensive laboratory analysis.
9.2
Corrective Action
If the results for the laboratory quality control procedures are outside the quality control criteria, the lab’s project manager should be contacted and the results should be reviewed to identify the source of the problem. The lab must
follow prescribed procedures to resolve the problems. Such procedures may
include retrieving missing information, recalibrating the measurement system,
and/or reanalyzing the sample if the holding time has not been exceeded and if
the volume is sufficient.
If the ion balance error is greater than 10 percent and the results for the quality
control procedures meet the MQOs, consider adding other ions in the analysis
to account for the observed error. Note any pattern in the error and note
whether the error exceeds than 10 percent in more than one sample. If all the
errors are of the same charge (positive or negative), it is likely that a significant
ion has not been included in the analysis. If the errors are of different charges,
they are more likely analytical.

Data Management Procedures
This section addresses both field water level measurements and field and laboratory water quality data. All data will be maintained electronically; therefore,
field data must be converted to a digital format from the notebooks.
Water quality data should be maintained in a Microsoft Access database. Field
headers should be consistent with DOE’s EIMS database. Data entered using
these field names can then be easily uploaded into the DOE EIMS. Similarly,
data from the EIM could be easily incorporated into the project database. The
location data needs to be entered only once for each well. The results data
needs to be entered each time data is collected. These two tables are crossreference using the field (User_Location_ID).
Tables 7a and 7b summarize the headers that should be used for the location
and results data, respectively. To be consistent with the EIM requirements, all
the wells should have a DOE well tag identifier. Because some wells that we
recommend for monitoring (Table 1) are not included in the DOE database,
they do not currently have a well tag ID; DOE will need to provide a well tag
ID for these wells that are included in the program. In addition to using the
field headers provided in Tables 7a and 7b, it is important to use the information provided in these tables to fill these fields in correctly.
If data is uploaded to the EIMS, field results for dissolved oxygen and pH
should not be included since the analytical methods are different than recommended and would thus not provide adequate comparability.
11
Audits & Reports
The data will be made available electronically to anyone within the Planning
Unit who requests it, either as Excel workbooks or as an Access database. Hydrographs and water-quality trend plots will be produced annually.
12
Data Verification & Validation
Data verification involves examining the data for errors, omissions, and compliance with quality control (QC) acceptance criteria. The analytical laboratory
is responsible for performing the following functions:
•
Reviewing and reporting QC checks on instrument performance such as
initial and continuing calibrations.
19
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
•
Reviewing and reporting case narratives. This includes comparison of QC
results with method acceptance criteria such as precision data, surrogate
and spike recoveries, laboratory control sample analysis, and procedural
blanks.
•
Explaining flags or qualifiers assigned to sample results.
•
Reviewing and assessing the lab’s performance in meeting the conditions
and requirements set forth in this sampling plan.
•
Reporting the above information to the project manager or lead.
After measurement results have been recorded, the results are verified by the
office lead to ensure that:
•
Data are consistent, correct, and complete, with no errors or omissions.
•
Results of QC samples accompany the sample results.
•
Established criteria for QC results were met.
•
Data qualifiers are properly assigned where necessary.
•
Data specified in the Sampling Process Design were obtained.
•
Methods and protocols specified in the Quality Assurance Project Plan
were followed.
The analytical laboratory is responsible for verifying all analytical results. Reports of results and case summaries provide adequate documentation of the
verification process. Laboratory analytical data will be reviewed and verified
by comparison with acceptance criteria according to the laboratory’s established data review protocol. Appropriate qualifiers will be used to label results
that do not meet quality assurance requirements. An explanation for data qualifiers is provided.
The analytical laboratory will include in its report a comparison of the results
of quality control tests (described in Section 10) to the MQOs established in
Section 6. The laboratory data is considered valid if:
•
These tests meet the MQOs.
•
Ion-balance error is less than 10 percent. Under this condition, it can also
be assumed that all significant ions have been analyzed.
Comparing the field data to the laboratory data:
•
If after 1 year, the field measurements for TDS and dissolved oxygen are
within than 5 percent of the lab measurements, then the field measurements
could be considered valid and the lab measurements can be discontinued to
save costs.
20
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
Field results will also be verified by field staff before leaving the site after
measurements are made. As described in Section 8.5 Recordkeeping, detailed
field notes will be taken to meet the requirements for documentation of field
measurements. The field lead is responsible for checking that field data entries
are complete and error free. The field lead should check for consistency within
an expected range of values, verify measurements, ensure measurements are
made within the acceptable instrumentation error limits, and record anomalous
observations.
13
Data Usability Assessment
Data usability assessment follows verification. To analyze data for its usability,
the project lead will consider precision, bias, completeness, comparability, and
documentation of adherence to protocols. This involves a detailed examination
of the data package using professional judgment to determine whether the
method quality objectives (MQOs) have been met. The project manager examines the complete data package to determine compliance with procedures outlined in this Plan. The project manager is also responsible for the data usability
assessment by ensuring that the MQOs for precision, bias, and sensitivity are
met.
Part of this process is an evaluation of precision. Precision will be assessed by
calculating relative percent difference (RPDs) for field and laboratory duplicates. Laboratory duplicates will yield estimates of precision performance at
the laboratory only. Field duplicates will indicate overall variability (environmental + sampling + laboratory). Acceptable precision performance is outlined
in the MQOs (Table 3).
Completeness will be assessed by examining:
•
number of samples collected compared to the sampling plan;
•
number of samples shipped and received at the laboratory in good condition;
•
the laboratory’s ability to produce usable results for each sample; and
•
sample results accepted by the project manager.
Data will also be examined for extremes (i.e., against historical records and
against the distributions of these project data). Extreme values will require
logical explanations. Identified sources of bias will be described. After the assessment described above, usability will be identified:
21
Ambient Groundwater Monitoring Program and
Data Quality Management Plan for the WRIA 16 Planning Area
•
If the MQOs are met and the RPDs are acceptable, documentation is thorough, the sample data will be identified as useable.
•
If the ion balance error is acceptable, yet the MQOs and RPDs are unmet,
the data will still be considered useable.
•
All data submitted to DOH and included in its database will be considered
useable.
•
Data collected by the Skokomish Tribe will be considered useable if it
meets tribal data quality objectives. All efforts should be made to encourage the analytical methods used by the Tribe are the same as those used as
part of this program.

Appendix A: Example Written Agreements
to Monitor Individual Wells
WELL ACCESS AGREEMENT
Purpose:
This Access Agreement is entered into between a representative of Mason and Jefferson
counties, (hereafter referred to as the “representative”) and the well owner, (hereafter referred to as “the Owner”), for the purpose of obtaining access to, and groundwater level
measurements in, water wells operated by the Owner. This agreement describes the nature
of measurements to be collected by the representative and, by signature of the Owner, provides permission to the representative for temporary access to the Owner’s well(s). This Access Agreement also serves to indemnify the representative for all damages that may occur
to the Owner’s well(s) during the measurement of water levels by the representative.
Introduction:
As part of ongoing watershed planning efforts, Mason and Jefferson Counties have contracted a representative to measure groundwater levels in wells within selected areas of Water Resource Inventory Area (“WRIA”) 16, which includes parts of Mason and Jefferson
Counties. These measurements will be used to develop water-table maps for the area. Wells
of interest include those used for drinking water supplies (private-residential and publiccommunity), irrigation, industrial supplies, dewatering, testing, and environmental monitoring. Mason and Jefferson Counties, and the WRIA 16 Planning Unit encourage all water
well owners and operators to assist the field staff in locating and accessing these wells.
Data Collection:
The representative will measure groundwater levels using an electric water-level sounder
manufactured specifically for the water-well industry. All “downhole” components of
sounder will be cleaned before and after use in each well. These components, which consist
of a 1/4-inch-diameter probe attached to plastic-coated electrical wire, transmit signals to an
indicator switch at the land surface. The sounder will be lowered into the well until it contacts the water surface and depth to water is recorded. After collecting the water level data,
the sounder will be removed from the well. The Owner’s well cap will be reinstalled at the
Page 1
WELL ACCESS AGREEMENT
completion of the representative’s water level survey. The representative’s work will be performed in accordance with standard accepted hydrogeologic practices.
The representative may also collect a water sample to analyze it for fundamental water quality parameters. If a sample is collected, the water sample will be collected from the nearest
faucet or spigot. The sample bottle containers will not contact the faucet or the spigot. The
representative will need to make sure that the well has pumped at lest three borehole volumes before collecting a sample. The representative will calculate the pumping time required
to do this based on the water level information and well information and the pumping rate.
The representative will estimate the pumping rate using a stopwatch and a container of
known volume.
Agreement:
The Owner agrees to provide the representative access to water wells for the purpose stated
above. Although the chance of damage to the Owner’s well is extremely small, the Owner
agrees to indemnify the representative for all damages to the Owner’s property that may occur while obtaining water level measurements. The representative will coordinate with the
Owner in collecting all water level information at a time that is suitable to the Owner. The
undersigned agree to the terms stated in this Access Agreement.
