PROBLEM DEFINITION/BACKGROUND The Kuskokwim River is the longest free flowing river in the United States. Originating in the Alaska Range, the river drains into the Bering Sea at the Yukon-Kuskokwim delta. Kuskokwim is a loose transliteration of a Yup'ik language word meaning “big slow moving thing.” The Kuskokwim drainage contains 38 communities, and can be defined in three regions; lower, middle, and upper. The middle Kuskokwim Region extends northwest from the hub community of Aniak, and contains Athabascan, Yup'ik and Euro-American residents. The Native Village of Georgetown can be found in the middle Kuskokwim region, amid the Kilbuck-Kuskokwim Mountains, where the Kuskokwim converges with the George River. Georgetown is located between the villages of Crooked Creek and Red Devil (Figure



1). The nearest highway system is 260 miles east; Georgetown is only accessible via plane, river boat during summer months, and snow machine during the winter. Mining has surrounded the village of Georgetown since its origination in 1909, and continues to be prominent in the area to this day (Figure 1). The environmental impacts of both previous and potential mining operations are the main area of focus and study for the members of Georgetown. The health of the Kuskokwim River and its tributaries is essential to fish, wildlife, and human populations in the region.



Figure 1: Location of Mining Sites near Georgetown

Gold was found along the George River in 1909, bringing in nearly 300 prospectors and thus establishing the village of Georgetown. Both the river and the settlement were named for the first three traders at the site: George Fredericks, George Morgan, and George Hoffman. In 1911, a fire swept through the settlement and destroyed most of the buildings. As mining declined, Georgetown members were forced to leave the area due to lack of employment opportunities. Nearly 80% of members still live in the area, with 34 known members living in Bethel and another 36 in other nearby Kuskokwim River villages. It wasn't until the passage of ANCSA and the opportunity to take ownership of

Abandoned Red Devil Mercury Mine

Proposed Donlin Gold Mine



ancestral lands, that former Georgetown residents and their descendants had an opportunity to move back home. Red Devil Mine, an abandoned cinnabar mine and mercury production facility, is located approximately 14 miles upstream from Georgetown (Figure 1). Mining operation occurred from 1933 until 1971, with a yield of approximately 35,000 2.5 - quart flasks of mercury (BLM). Operators conducted extensive underground and surface mining, disposing of the tailings and processing waste on site. The BLM began addressing hazardous materials and physical safety hazards at the abandoned mine in 1987. The primary metals of concern at the mine site include mercury, arsenic, antimony, and lead. A Remedial Investigation/Feasibility Study of Red Devil began in 2008, led by the BLM, in cooperation with the EPA under CERCLA. During the Remedial Investigation, it was verified that metals left behind from the processing are leaching from the tailings and entering ground and surface waters, meaning potentially long term environmental impacts to the area. The overall purpose of this investigation is to characterize the site, determine what potential risks the mine site may have on human health and the environment, and what can be done to mitigate those risks. “Early Action” was completed for the removal of tailings near Red Devil Creek during the summer of 2014. The “Early Action” included adjusting the path of and installing a retaining wall for the creek located adjacent to the tailings piles and establishing a sediment trap further downstream to help mitigate tailings migration in the creek in the hopes that this will reduce contaminant entry into the Kuskokwim River. As of the publication date of this report, this study and investigation is still underway and further action is being considered. Donlin Gold, LLC is currently in the permitting process for the construction of a proposed open-pit gold mine, to be located just 20 miles from Georgetown (Figure 1). Donlin Gold mine expects to process 59,000 short tons of ore per day after the 3 year EIS process (initiated in 2012) is completed. The final EIS has been released and a record of decision is expected in 2018 for current wetland permits submitted to US Army Corps of Engineers. The life of the mine operation is expected to be 27+ years. Estimates have put the mine’s gold potential production at an estimated 1.3 million ounces of gold per year, which would make it one of the world's largest gold-producing mines. Potential environmental impacts and human health concerns associated with the Donlin Gold mine exist. They include but are not limited to: the risk of mercury contamination, acid mine drainage, release of cyanide from the cyanide vat leaching process, and release of heavy metals such as arsenic, lead, antimony, and cadmium. Intermittent water quality sampling and analysis began in Georgetown in 2003. Due to impending development in the area, including the construction of the Donlin Gold open pit mine, the need for the development of baseline water quality for Georgetown was realized. The primary goal of water quality monitoring was to document existing conditions in Georgetown, prior to development in the area, so that should changes occur, both the source and its impact on water quality could be easier to identify.



A6. PROJECT/TASK DESCRIPTION The Georgetown Tribal Council is the federally recognized tribe for the Native Village of Georgetown, and is dedicated to protecting our waters and the life they sustain. The objectives of the Georgetown Water Quality Monitoring Program are to: • inventory baseline water quality in the waters of the Kuskokwim and George Rivers; • detect and report significant changes and track water quality trends; • increase public awareness on the importance of water quality; and • work with other communities on the Kuskokwim to maintain a region wide database of water quality information. To promote these objectives, Georgetown has selected water quality parameters that will enhance understanding of overall environmental health and allow us to track possible changes due to environmental development and mining in the area (see Methods Section of the 2014 and 2016 GTC Water Quality Reports for a discussion of the importance of each testing parameter).

Refinements in methods or additional testing parameters may be incorporated in this project in the future if it is determined that such changes would enhance efforts to achieve project goals and assuming additional funding is available. Any such changes will be submitted for EPA and ADEC approval. Depending on the data use intent, data may be used by government agencies, landowners, and other resources managers to enhance understanding of basic water quality status and to identify water quality trends. At the time of this QAPP revision, the Georgetown Tribal Council plans to test surface water samples and groundwater samples for the following parameters on site: Dissolved oxygen, temperature, conductivity, salinity, pH, and total dissolve solids (TDS). In addition, samples will be obtained and sent to Test America for the analysis of the following: Semi-volatile organic compounds (SVOCs), volatile organic compounds (VOCs), Hardness, Total Arsenic, Dissolved Arsenic, Cadmium, Lead, Nickel, Antimony, and Mercury.

As applicable, the EC will record narrative environmental data at each sampling event, and will photograph each site. These visual and other observations complement the quantitative physical and chemical data collected at each established monitoring site. Data collected is entered into the Kuskokwim River Water Quality database, housed at the Georgetown Tribal Council office. Test results can then be compared to state and federal water quality standards as applicable. The Georgetown Tribal Council will work with other interested parties to maintain the Kuskokwim River water quality database and web mapper. This data will be made available on the GTC’s website and a data analysis and summary report will be published annually. Georgetown Tribal Council’s water quality monitoring program is an on-going project designed to continue as long as funding allows. Table 1 shows an Annual Schedule of Tasks to be conducted during the life of the project.

A7. QUALITY OBJECTIVES AND CRITERIA FOR MEASUREMENT DATA Data Quality Objectives (DQOs) are the quantitative and qualitative terms used by EPA to describe how good the data needs to be in order to meet the project's objectives. DQOs for measurement data, also commonly referred to as data quality indicators, are precision, accuracy, representativeness, completeness, comparability, and measurement range (sensitivity). The overall QA objective for analytical data is to ensure that data of known, acceptable, and legally defensible quality are generated. To achieve this goal, data must be reviewed for 1) precision, 2) accuracy or bias, 3) representativeness, 4) comparability, and 5) completeness. The summary of DQO requirements for this project listing the suite of parameters for analysis, analytical methods, frequency of collection and analysis of QA/QC samples, precision, accuracy, and completeness requirements, sample container and preservative requirements, and holding times are shown in Table 2 – Data Quality Objectives Summary Table, attached at the end of this section. Precision and Accuracy Precision is the degree of agreement among repeated measurements of the same characteristic, or parameter, and gives information about the consistency of methods. Accuracy is a measure of confidence that describes how close a measurement is to its “true” value. Replicate measurements will be performed during each testing event, monitoring and training sessions and during annual performance evaluation and re-certification. Replicate analysis acceptability criteria and applicability for each environmental measurement are described in the method's SOP. Field analytical precision will be evaluated by the relative percent differences (RPD) between field duplicate samples and/or replicate readings using the following formula: (R1 - R2) RPD = x 100 ((R1 + R2)/2)

Where: R1 = the larger of the two replicate values R2 = the smaller of the two replicate values

Field accuracy will be routinely checked according to the instrument and analytical method accuracy requirements (see Table 2 - Summary of Data Quality Objectives) of each parameter. Commercial laboratory Accuracy and Precision: QC samples for accuracy and precision in a laboratory setting may include the analysis of the following: duplicate samples, laboratory control check and laboratory control check duplicate samples (LCS/LCSD) and/or matrix spike and matrix spike duplicate (MS/MSD) sample analyses and addition of surrogate spikes. LCS and LCSD analyses are blank samples (from the lab) injected (spiked) with a known concentration of target compounds processed on the same date and same way and analyzed with the routine samples. LCS/LCSDs are usually performed in cases where insufficient amount of routine samples are available for the MS/MSD QC analyses. MS/MSD analyses are routine samples injected with a known concentration of target compounds processed on the same date



and same way and analyzed with the routine samples. Surrogate spike is a compound that is not one of the target compounds but belongs to same chemical category and has the same characteristics and behaves similarly as the target compounds. Accuracy are determined by calculating the recoveries (%R) of the target compounds spiked into the LCS/LCSD and/or MS/MSD samples or the surrogate spiked into the sample. Laboratory Accuracy is calculated as follows:

% R = SQ – NS x 100 Spike where: %R = percent recovery SQ = the concentration of the spiked compound measured in the routine or blank sample NS = concentration of the target compound native to the unspiked routine or blank sample Spike = the concentration of the target compound spiked in the routine or blank sample

Laboratory precision is calculated as follows: (R1 - R2) RPD = x 100 ((R1 + R2)/2)

where: RPD= Relative Percent Difference and R1 and R2 are the initial and duplicate measurement values, respectively

In case of MS/MSD and/or LCSD/LCSD

R1 = % Recovery of the target compound in the initial analysis (from MS or LCS) R2 = % Recovery of the target compound in duplicate analysis (from MSD or LCSD)

Data Representativeness Representativeness is the extent to which measurements actually represent the true environmental condition. It is the degree to which data from the project accurately represent a particular characteristic of the watershed that is being tested. Representativeness of samples is ensured by adherence to standard field sampling, measurement and laboratory protocols. The design of the sampling scheme and number of samples for this project provide representativeness of the part of the watershed being monitored. As a whole, representativeness of the samples collected for this project will be determined during data assessment and data interpretation phase. Data Comparability Comparability is the degree to which data can be compared directly to similar studies. Using standardized sampling protocols, the same or comparable analytical methods and units of reporting with comparable sensitivity helps ensure comparability. The Georgetown Tribal



Council has selected testing methods that are EPA-approved and/or currently being employed by other water quality monitoring programs throughout the country. As the program expands, site selection will favor locations where previous water quality monitoring has taken place. Efforts will be made to duplicate the effort of past studies where possible. Data Completeness Completeness is the comparison between the amounts of usable data collected versus the amount of data called for in the sampling plan. Completeness is the percentage of valid results obtained compared to the total number of samples taken for a parameter. The target completeness goal for this project shall be 90% or better. %Completeness is calculated using the following formula:

% Completeness (per parameter) = # of valid results x 100 Total # of samples taken The parameters measured, analytical methods used, method sensitivity, QC samples, holding times, preservative, and containers needed for this project are listed in Table 2 – Summary of Data Quality Objectives. Table 2 will be used as the criteria for evaluating and determining the quality, bias and usability of the data generated for the project conducted. This will be performed during the data validation process.

A8. SPECIAL TRAINING NEEDS/CERTIFICATION To be able to participate in the Georgetown Water Quality Monitoring Project, participants are required to participate in a training program that meets the USEPA’s Office of Grant and Debarment requirement for field competency. A9. DOCUMENTS AND RECORDS All data gathered during this project is recorded on site at the time sampling occurs using a write-in-the-rain field notebook. Appendix B contains the datasheet for this project. Personnel are instructed to fill out the information for the datasheet legibly and completely. Data is entered using an indelible marker. If a mistake is made, one line is drawn through the characters in question and the new characters are entered to the immediate right of the lined-out entries. The date and monitor’s initials are entered immediately after the new characters. Personnel are also instructed to use the comment section of the data sheet to report any problems or abnormalities with sampling procedures or equipment. All records and documents are kept at the Georgetown Tribal Council’s office and are available for inspection at any time. Monitoring equipment and supplies are inspected by the Tribe upon receipt and again during QC sessions. Equipment inspection form and corresponding SOPs for each method SOP are kept up-to-date for each equipment or measurement kit. B. DATA GENERATION AND ACQUISITION B1. SAMPLING PROCESS DESIGN (EXPERIMENTAL DESIGN) Sample Site Selection In order to meet the objectives outlined in Section 6, the GTC identified four sampling locations at which to collect baseline water quality data (Figure 2, Table 3). The GTC Environmental department and Monaska Consulting determined site selection. These sites were chosen based on the following criteria:

• Their importance to the community. Georgetown members plan to use both the groundwater wells and the freshwater sources in the area for human consumption of water and/or fish. The George River and Kuskokwim River have been historically and are currently used for access to fish, a vital subsistence resource.

• The sites were chosen based on the layout of the Kuskokwim and the George Rivers and their proximity to the Native Village of Georgetown. They are representative of the true natural environmental condition of the area surrounding Georgetown.

• Consideration was also given to logistical access and safety. Sites were selected that are safe and reasonably accessible.

In 2005, Monitoring well 1 (MW-1) was installed to supply the Community Building with groundwater and Monitoring well 2 (MW-2) was installed to meet general water requirements. An outline of methods to install these wells is available in the 2006 EPA approved QAPP. Currently, the only purpose for MW-1 and MW-2 is for annual water quality testing and future use. The official establishment of baseline water quality testing and analysis at these sites, as it continues to this day, began in 2008. Historical baseline data for all four sites can be found in Appendix A. Sampling Parameters & Collection Frequency As described in Section 6, testing parameters are selected based on their usefulness in inventorying water quality and protecting the general “health” of the water sources in question. Consideration was also given to data collected in previous years and to the costs related to testing each parameter as related to available funding. The parameters to be tested are listed in Table 4.

Due to the location of Georgetown, sampling events are scheduled to occur twice during the year; once after the river breaks up in late spring/early summer and once prior to freeze up in late summer/early fall. Historically, data collection has occurred primarily in the months of June/July and August/September. Site Safety Plans The following safety precautions discussed below do not constitute a safety plan, and approval of this QAPP doesn’t constitute a safety plan approval. Sampling sites are selected, in part, because they are safely accessible. Personnel are instructed to use safe access routes and will be warned of site-specific hazards. At least two people are always present during sampling events. Personnel will use appropriate safety equipment during sampling and analysis. This will include: goggles or protective eye wear, rubber gloves, and life vests while in the boat. Personnel are advised to wear rubber boots and dress appropriately and be prepared for variable weather conditions. B2. SAMPLING METHODS Grab samples will be collected from the freshwater sites (KR-1 and GR-1) at the surface of the water. Groundwater samples will be obtained at MW-1 and MW-2 with the use of a 12V peristaltic pump. Sampling protocols for this project will be conducted as outlined in the Georgetown Tribal Council Water Quality Sampling Manual, which can be found in Appendix D. Samples for the analysis of dissolved Arsenic will be filtered at the laboratory. B3. SAMPLE HANDLING AND CUSTODY The project’s training certified field personnel will conduct all of the field parameter testing for this project. Split samples or samples identified for additional fixed-laboratory analyses will be collected by the Tribe and sent to laboratory within the analytical holding times. Contract laboratories shall meet the EPA’s Forum on Environmental Measurement’s policy for competency and shall be certified and/or accredited for the analyses the laboratory is contracted to analyze. The laboratory’s QA Manual and certification of accreditation can be found in Appendix C of this QAPP. Samples that require laboratory testing will be handled following this chain of custody procedure:

• Samples will be labeled (see Appendix D for GTC Water Quality Sampling Manual) and logged in a monitor datasheet upon collection. When working with commercial laboratories, sample bottles and labels may be provided.

• Once samples have been collected they remain with field personnel for sample processing and logged in for temporary storage, until they can be delivered to the lab.

• Samples will be the responsibility of the field crew and stay with the project personnel or designated representative at all times until shipment to the lab.

• Samples are stored, preserved and analyzed as outlined by the method's SOP. • Project personnel are responsible for coordinating sample transport to a laboratory for



analysis.

• Laboratory personnel will record the date and time the sample arrives at the lab. • Laboratory results and other contract deliverables are submitted the Tribes within 30 days of

sample receipt at the lab. • All results from the laboratory are reported in the annual report. • The certified clean and appropriate sample container, preservative, sample container label,

cooler and chain of custody shall be provided by the laboratory to the Tribe. B4. ANALYTICAL METHODS Table 2 summarizes the analytical methods that will be used for each analyte. These methods were chosen after consideration of time and funding limitations, project goals and objectives, and methods available. Table 5 lists the target compounds with corresponding reporting limits and MDLs from Test America for VOCs, SVOCs, total and dissolved Arsenic, lead, antimony, nickel, and mercury, along with the analytical methods used. Test America laboratory manager, Dennis Bean (as of March 2018), can be contacted at Test America for any questions regarding SOPs. His contact information can be found in section 1.1 of Appendix C.

B5. QUALITY CONTROL REQUIREMENTS The following quality assurance and quality control measures are taken to assure the quality of the data collected:

• QC For Field Measurements: Replicate measurements shall be performed in the field every 10 sample measurements. Precision of the replicate analyses shall be within the acceptable criteria set forth by the instrument or the method SOP. Only replicate measurements that meet the precision criteria will be entered in the project database. Should a problem arise due to unacceptable precision results, no other measurements for the parameter will be conducted until the cause of the problem is identified and resolved. Problems encountered will be documented in Corrective Action Form (Attachment 2). Deviations from the QAPP shall be documented in the Sample Alteration Form (Attachment 1).

• Calculation of precision, accuracy, and completeness are outlined in Section A-7.

• Depending on the frequency of the sample collection and measurement activities, split

samples may be collected and analyzed by a laboratory. Split confirmatory samples may also be sent to the commercial laboratory in case questionable/anomalous high results were obtained in the field. The contracted laboratory must meet EPA’s Competency Policy (See section B3 and Appendix A).



• QC For Chemical Analysis: The commercial laboratory performing the split or confirmatory analyses shall have the following QC analyses included in their data package deliverables: Results for method blank, sample and QC sample surrogate recoveries, and a laboratory control/duplicate sample and/or matrix spike/duplicate sample analyses.

• Three levels of data verification will be employed, i.e., during sample collection, data

documentation and data entry, and generation processes. Data that did not meet the DQO of the project are appropriately flagged in the database during the data validation process. Qualifiers from the laboratory will be noted in the database, along with any data that did not meet sampling DQO for the project.

• All calculations are performed automatically after entering the data in the database, thus,

removing or minimizing the occurrence of errors.

• Data shall be evaluated for consistency and reliability and may necessitate re-sampling and sample analysis via commercial laboratory.

• Internal and external QA assessments shall be performed to assess the progress and

effectiveness of the project annually.

• The Georgetown Tribal Council Baseline Water Monitoring Project periodically receives comments and technical advice from the Environmental Committee, serving as the TAC.

• Additional QC activities may be conducted as dictated by the analytical methods of SOPs

used in the collection of environmental measurements. B6. INSTRUMENT/EQUIPMENT TESTING, INSPECTION, AND MAINTENANCE The training kit, manufacture’s manual, and the environmental measurement SOPs describe the proper handling and maintenance of equipment. Proper equipment handling and maintenance is also emphasized during all training and QC sessions. Initial inspection, testing, and assurance that all sample collection and measurement kits meet the technical specifications as specified by the method and/or SOP are the responsibilities of TTT Environmental, the company which provides sampling equipment, if rented, and are performed by the tribe upon receipt of the equipment/instrumentation and prior to distribution for use. Initial inspection, testing, and assurance for all equipment currently owned by Georgetown Tribal Council will be completed prior and after use in the field.



The following are the responsibilities of the Tribes with regards to instrument/equipment maintenance:

(1) Before each sampling event, the monitoring personnel shall inspect and test all equipment and reagents and ensure that they are clean and in good working condition.

(2) If any equipment or chemical reagent is found to be defective in any way, the Tribe shall contact the manufacturer and arrange for immediate replacement or repair.

B7. INSTRUMENT/EQUIPMENT CALIBRATION AND FREQUENCY All field instruments and equipment shall be calibrated before use following the calibration procedures described in each method SOP and the manufacturer’s manual. Meters will be calibrated each day prior to use. All commercial laboratory instrumentation and equipment used in the analysis for this project shall be calibrated prior to sample analysis in accordance with the technical specifications and procedures specified in the analytical method used. B8. INSPECTION/ACCEPTANCE OF SUPPLIES AND CONSUMABLES Equipment and/or supplies ordered from TTT Environmental are inspected upon arrival by project personnel. Instruments or supplies that do not meet standards are returned for replacement. GTC equipment is inspected and calibrated prior to each sampling event in accordance with technical specifications. If any equipment fails the inspection or calibration, the manufacturer is contacted and a replacement will be procured. The laboratory, Test America, provides QC grade certified clean sample containers including the preservatives for the VOCs, SVOCs, hardness, and dissolved and total metals analyses. B9. NON-DIRECT MEASUREMENTS Required longitude and latitude information for monitoring sites is derived by using USGS topographic maps at 1:63,360 and confirmed using GPS coordinates taken at the site by the project personnel. Sites may be plotted and spatially checked using a Geographic Information System (GIS) computer-mapping program (e.g., ArcView or ArcGIS). This information is used to identify monitoring sites and assign site numbers for entry into the monitoring data system.

Historical water quality data on the sites will be collected and summarized. This data will be used in the site selection process. Additional water quality, fish and wildlife habitat, physical river characteristics, weather conditions, and other data pertaining to the watershed will be gathered and utilized in writing the annual report. Historical data will be analyzed to assess direct comparability and may be qualified or excluded from trend analyses in annual reports. Only data of known and documented quality will be used in this project. Water quality data will be evaluated by comparison to state and federal water quality standards as applicable.



B10. DATA MANAGEMENT Monitoring personnel shall collect and report data in a notebook using information for data sheets (Appendix B) provided for this project. All observational data, water quality data, and field measurements are recorded at the time of sampling and analysis. All personnel sign and date the datasheets. The data sheets are kept and maintained in an organized file in the Georgetown Tribal Council office. Field datasheets and other sample documentation shall be initially reviewed by the Environmental Coordinator or sample collector and peer reviewed by the Tribal Administrator prior to data entry to the project database. Another review for transcription errors, precision, completeness, anomalous data, and other general problems shall be conducted after data entry to the database. The project personnel shall ensure that data generated are accurately entered into the Microsoft 2007 Access or Excel database which is compatible with the schema format required for the EPA’s Water Quality Exchange (WQX). Once in the WQX database, the data will be available for sharing through the Internet at the Alaska's Cooperatively Implemented Information Management System (CIIMMS) website. Data are reviewed regularly by the project personnel, and will be presented to the Georgetown Tribal Council in an annual report (see Section C2). C. ASSESSMENT AND OVERSIGHT C1. ASSESSMENTS AND RESPONSE ACTIONS C1.1 Project Level Assessments (Internal Project Assessments)

• Depending on the frequency of the sample collection and measurement activities, split samples shall be collected and analyzed by a laboratory. Split confirmatory samples shall also be sent to the laboratory in case questionable/anomalous high results were obtained in the field.

• Three levels of data verification shall be employed, i.e., during sample collection, data

documentation and data entry, and generation processes. Data that did not meet the DQO of the project are appropriately flagged or qualified in the database during the data validation process.

• The Environmental Committee will review this QAPP and the overall project design annually

and may suggest procedural refinements or additional testing procedures. This may include new parameters to be measured or changes to procedures currently in use. Any such changes will be subject to EPA approval. The project is open to EPA management or technical system audits at their discretion.

• An internal QA assessment and applicable technical system review (TSR) shall be conducted

by the project, chemical, habitat, and biological QA officers for the project to assess the progress and effectiveness of the project annually.



C1.2 Program Level Assessments (External Project Assessments)

• A TSR of the project shall be conducted by EPA, State, or contactor to assess the progress and effectiveness of the project annually, or as requested by the program.

• Depending on funding and availability, additional performance evaluation sample may be

submitted blind to the project personnel for field measurement analysis at least once per year. A performance evaluation sample may be submitted blind to the contract laboratory to test proficiency.

C1.3. Response and Corrective Actions Problems encountered during sample collection and data generation shall be documented and handled accordingly and as soon as possible in a Corrective Action Form (see Attachment 1 & Attachment 2). No measurements will be generated by an instrument or piece of equipment that did not meet the technical specifications of the manufacturer or the method SOP. Problems that may have a big impact on data quality shall be properly documented and resulting data will be flagged accordingly. Any failure to meet data quality objectives will be evaluated. If the cause is found to be equipment failure, calibration and maintenance procedures will be reassessed and improved. If the problem is found to be personnel error, personnel will work with the Project QA Officer to resolve the problem. If accuracy and precision goals are frequently not being met, QC sessions will be scheduled more often. If failure to meet program specifications is found to be unrelated to equipment, methods, or personnel error, the QAPP may be revised. Revisions and subsequent modifications and amendments to this QAPP shall be submitted to the EPA Region 10 Quality Assurance Manager for review and approval. C2. REPORTS TO MANAGEMENT Annual reports will be produced for each year and will describe activities during each calendar year. These reports will consist of data results, interpretation of data, information on project status, project highlights, accomplishments, and results of audits and internal assessments. The EC is responsible for the preparation of the Annual Reports. The project personnel shall be responsible for the Annual report production and distribution. Annual reports will be forwarded to ADEC (optional), the regional office of EPA and all other parties listed in Section A3 of this document as well as the Environmental Committee. Summaries of all reports highlighting the assessment results, project status, and achievements will be distributed to the Georgetown Tribal Council.



D. DATA VALIDATION AND USABILITY D1. DATA REVIEW, VALIDATION, AND VERIFICATION REQUIREMENTS All data collected by project personnel is subject to review by the Chemical and Habitat QA Officer, Biological QA Officer, Project QA Officer, Project Manager, Field/Sampling Leader, and the Laboratory Manager/Leader to determine if the data meet QAPP objectives. Decisions to reject or qualify data are made by the Project QA Officer. D2. VALIDATION AND VERIFICATION METHODS D2.1 Data Verification For Field Measurements: Data sheets and/or chain-of custody forms must be filled out completely and signed by the samplers at the time of sampling and analysis. There will be at least three levels of data verification for this project, (1) field data sheet and data generation documentation review by the sample collector, (2) peer review by a project staff other than the sample collector and (3) cursory and transcription error data review and evaluation by the project EC or TA. During this process, datasheets for calibration and measurements and chain-of-custody records shall be checked and evaluated for precision, accuracy, missing or illegible information, errors in transcription and calculation, and values outside of the expected range. When review is completed and any concern addressed, each datasheet is signed and dated by the Environmental Coordinator. If data quality questions cannot be adequately resolved, data will not be entered into the data system and the EC will arrange for corrective measures (i.e. re-training, equipment re-calibration, etc.). Any changes made to data are documented, initialed and dated, and any action taken as a result of the data review is specifically recorded on the datasheet below with the reviewers’ signatures and dates of signatures. D2.2 Data Validation The laboratory conducts three levels of data verification – first from the analyst, then the analyst’s supervisor, and finally, the laboratory QA Manager prior to the release of the data. Data that did not meet the DQO of the project are appropriately flagged or qualified in the database during the data validation process. On a bi-annual basis, the EC prints the data and proofs it against the original data sheets. Errors in data entry are corrected and inconsistencies are flagged for further review. Data shall be presented annually using graph and report formats to document baseline water quality, identify trends, and detect deficiencies in data collection or program design. Annual reports will include discussion of any data quality problems and will be distributed to all data users (see Section C). Members of the Technical Advisory Committee will be asked to review these reports and offer suggestions for improving the Georgetown Tribal Council Baseline Water Monitoring Project.



D3. RECONCILIATION WITH USER REQUIREMENTS Data generated by this project shall be evaluated and assessed in accordance with the DQO requirements listed in Table 3 and the technical specifications and QC acceptance criteria set forth by the analytical methods and SOPs used for each environmental measurement. All data generated shall be reported in the database. Data that were slightly outside the DQO goals of the project shall be appropriately flagged or qualified in the database with a short narrative defining the qualifier and its effect to the quality of the data.

APPENDIX C – FEM POLICY COMPETENCY RECORDS



Due to the large volume of Test America Inc’s QA Manual, only the Statement of Qualification is housed in this Appendix. Additional documentation can be provided upon request, and is stored in the GTC filing system. Georgetown Tribal Council corresponds with the laboratory in Anchorage, but many of our analyses are sent to Seattle for completion. For this reason, certifications and statements of qualification are provided for both laboratory locations.
