INTRODUCTION

This Quality Assurance Program Plan (QAPP) is a project-specific document developed for the Wastewater Treatment Facility (WWTF) at Eielson Air Force Base (AFB), Alaska. In specific terms, this QAPP presents the policies, organization, functions, and quality assurance/quality control (QA/QC) requirements designed to ensure that the data used in project decision making are scientifically valid and defensible, and establishes the protocols and documentation requirements necessary to ensure that data are collected, reviewed, and analyzed in a consistent manner. In conjunction with the permit conditions presented in Appendix A and the laboratory Quality Management Plan presented in Appendix B, the QAPP will guide the technical and quality aspects of the field and laboratory activities conducted for the monitoring program and ensure that quality and consistency are maintained.

This QAPP is required reading for the personnel participating in the project. The project personnel will comply with the procedures as written and approved in the QAPP to maintain the comparability and representativeness of the data collected in support of this project.

The QAPP is a dynamic document and will be revised or updated to reflect any changes in organization and procedures.

A5. Problem Definition/Background

This QAPP ensures that the data collected and analyzed under this permit are valid and verifiable. If implemented correctly, this QAPP provides the level of precision, accuracy, and representativeness that yields data to help ensure that State of Alaska Water Quality Standards (WQS) are met and that water quality uses (public health and public resource protection) are protected.

The Eielson AFB WTF discharges drinking water filter backwash and bypass well water into Garrison Slough. Upstream sampling is performed to establish background concentrations of Total Iron and Arsenic. Effluent sampling is performed at the outlet weir of the constructed settling pond, where the water enters Garrison Slough, and Mixing Zone sampling is performed 500 feet from the weir at the Central Avenue culvert.

A6. Project/Task Description

The following section describes the monitoring to be performed at the Eielson AFB WTF in compliance with the permit conditions.

Upstream Monitoring Effluent limitations for Total Iron and Arsenic are determined by upstream background concentrations collected near the utilidor crossing of Garrison Slough. Sampling at the upstream and discharge locations is performed at the same time and same date

Effluent Monitoring Effluent monitoring consists of sample collection at the settling pond outfall and consists of dissolved oxygen, total iron, arsenic, pH, total suspended solids, total dissolved solids and total residual chlorine.

mailto:dec-wqreporting@alaska.gov

Mixing Zone Monitoring

Mixing zone monitoring consists of sample collection from Garrison Slough at a point 500 feet from the discharge weir at a culvert beneath Central Avenue. Mixing zone sampling includes total residual chlorine, pH, and dissolved oxygen. The upstream concentration of dissolved oxygen is used as the background concentration taken from the upstream sampling location.

A7. Data Quality Objectives and Criteria for Measurement of Data

Project Data Quality Objectives The data quality objective of this QAPP is to ensure that the data collected and analyzed are scientifically verifiable and valid, and can be used to determine compliance with the requirements of the permit.

Criteria for Measurement of Data Criteria for measurements of data are the performance criteria: the precision, accuracy, representativeness, comparability, and completeness (PARCC) parameter evaluations of the tests. These criteria must be met to ensure that the data are verifiable and that project data quality objectives are met.

The objectives for PARCC parameters are summarized in this section. The results will be recorded in field and laboratory logbooks. Additional sampling and analyses will be performed if results fall outside the specified ranges and when data quality objectives are not met. Proposed changes in data quality objectives will be submitted to ADEC for approval before implementation.

Note: The ADEC Water QA Officer keeps copies of the laboratory’s Quality Management Plan (QMP) on file. The QMP describes the laboratory measurement criteria. Therefore, QA/QC measures described in a contracted laboratory QMP are not repeated in this document.

Accuracy Accuracy is a measure of confidence that describes how close a measurement is to its “true” value.

Field accuracy is ensured by field instrument calibration according to the manufacturers’ instructions and by using standards and chemicals that are current (prior to expiration date), and by following proper sampling, sample handling and field analysis protocols.

Laboratory accuracy is normally determined by the percent recovery of the target analyte in spiked samples and also by the recoveries of the surrogates in the field and QC samples.

Accuracy is calculated as follows:

%R = Analyzed value x 100 true value

Where %R = percent recovery

Laboratory accuracy ranges are based upon control charts of historical data and are specified in the contracted laboratory QMP (kept on file at ADEC) and depend on the parameter being measured. The QA Officer will ensure that the analytical laboratory maintains accuracy by review of the laboratory’s in-house %R control limits and the results of QC samples analyzed with project samples.

The analytical laboratory will also maintain records of performance evaluation results on file and these results will be made available for review by ADEC upon request.

Precision Precision is the degree of agreement among repeated measurements of the same characteristic, or parameter, and gives information about the consistency of methods. Precision can be considered a product of the repetitiveness of monitoring.

Precision is expressed in terms of the relative percent difference (RPD) between two measurements (A and B), and is computed as follows:

RPD = A – B x 100

(A + B)/2

Field precision is measured by collecting and analyzing field duplicate samples.

Laboratory precision is ensured by measuring matrix spike/matrix spike duplicate (MS/MSD) samples and by the analysis of laboratory duplicate samples. The laboratory usually performs the analysis of one set of MS/MSD and duplicate samples per matrix measured. The control limit RPD is usually <20% but can vary widely depending on the analytical method. Control charts are a graphical representation showing the limits of acceptable data. The QA Officer will ensure that the analytical laboratory maintains precision by review of the laboratory’s in-house RPD control limits and the results of QC samples analyzed with project samples.

Analysts produce charts to document accuracy and precision in their testing. These charts are kept in the laboratory for data validation purposes. The Laboratory Project Manager will provide accuracy and precision records to ADEC upon request.

Representativeness Representativeness is the extent to which measurements actually represent the true environmental condition. The representativeness of the data collected was considered in the permit development process.

Comparability Comparability is the degree to which data can be compared directly to similar studies. Using standardized sampling and analytical methods and units of reporting with comparable sensitivity ensures comparability. USEPA-approved methods as listed in 40 Code of Federal Regulations (CFR) Part 136.3 will be used for standard measurements.

Completeness The completeness is the comparison between the amount of usable data collected versus the amount of data called for in the permit or certification. The completeness will be determined by comparing sampling and analyses with the requirements in the permit.

A8. Training and Certifications

The field sampling team as well as the analytical laboratory personnel will be trained in sampling methods, sample handling, chain-of-custody documentation, sample transport, and field and/or laboratory measurements. The Project Manager and/or the QA Officer are responsible for the training of staff that performs sampling, sample handling, and analyses activities. Records will be kept on file of these training activities and may be reviewed by ADEC.

A9. Documents and Records

Field logbooks, notebooks and/or data sheets will be filled out using waterproof and indelible ink and should not be erased. Changes must be made by crossing out errors and adding correct information. Logbooks should be bound with numbered pages.

Laboratory data results are recorded on laboratory data sheets, bench sheets and/or in laboratory logbooks for each sampling event. These records as well as control charts, logbook records of equipment maintenance records, calibration and quality control checks, such as preparation and use of standard solutions, inventory of supplies and consumables, check in of equipment, equipment parts, and chemicals are kept on file at the laboratory.

Procedural or equipment problems are recorded along with data results. Deviations from this QAPP are noted. Additional sampling and analyses will be performed when results fall outside the specified range and when DQOs are not met. Data results returned to ADEC will include information on field and/or laboratory QA/QC problems and corrective actions.

Chain-of-custody (COC) records will be kept with the sample transport, and will accompany the data results back to ADEC.

Training records and data review records will be kept on file in the field sampling team’s office as well as at the analytical laboratory and will be made available on request by ADEC.

The project records and documents are kept at least five years at the field sampling team’s office and the analytical laboratory and are available to USEPA and ADEC for inspection at any time.

B. Data Generation and Acquisition

B1. Sampling Process Design

Discharge Monitoring Monitoring will be performed in accordance with the Monitoring Permit. The testing to be performed according to the requirements of the Permit include: effluent flow, dissolved oxygen, total iron, arsenic, pH, total suspended solids, total dissolved solids, and total residual chlorine.

In April 2018, Perfluorinated Compound (PFC) testing for PFOS and PFOA was added to the WTF QAPP. As of April 2018, ADEC wastewater discharge monitoring requirements and discharge limits for PFCs are not included in permit requirements, however, they are included in this section for reference. The PFOS and PFOA limits are established in 18 AAC 75 .340 Table C (ADEC 2017) and are included below with footnotes.

Hazardous Substance Groundwater Human Health Cleanup Level2 (micrograms/liter)

Perfluorooctane Sulfonate (PFOS)9 0.40 Perfluorooctanoic Acid (PFOA)9 0.40

2. The “Human Health” exposure pathway is the cumulative exposure pathway through dermal contact, ingestion, and inhalation of volatile compounds from hazardous substances in the water.

9. Toxicity values for PFOS and PFOA were sourced from EPA’s Health Effects Support Document for Perfluorooctane Sulfonate (PFOS) (EPA 922-R-16-002), dated May 2016, and Health Effects Support Document for Perfluorooctanoic Acid (PFOA) (EPA 822-R-16-003), dated May 2016.

The suite of analysis for each source is dependent upon the probable pollutant for each source.

The methods for these analyses are presented in Table 2.

Upstream Monitoring Monitoring will be performed in accordance with the Discharge Permit. Methods will be according to 40 CFR 136.3 or equivalent (See Table 2).

Discharge Monitoring Monitoring will be performed in accordance with the Disposal Permit. Methods will be

B2. Sampling Methods

Samples and measurements taken as required by permit must be representative of the volume and nature of the monitored discharge.

When a sample is taken at a discharge line, a volume of water equal to at least ten times the volume of the sample discharge line will first be discharged into a bucket or similar container, to clear the line of standing water and possible contamination. If there is no discharge line faucet, the sampler may take the sample from the final effluent chamber, taking all safety and contamination-prevention precautions.

Samples will be identified as “composite” or “grab” on COC records and in field logbooks and field data sheets.

Grab Samples Bottles will normally be filled to the shoulder of the bottle, leaving a small space for expansion and mixing.

WWTF QAPP June 2011

Composite Samples Composite samples must consist of at least four equal volume grab samples, two of which must be taken during periods of peak flow (7-9 a.m. and 6-8 p.m.). Samples will be composited directly into the sample bottles. Between composite aliquots, bottles will be kept at a temperature of less than 6 degrees Celsius (oC).

The time of the initial portion of the composite, composite intervals, and the final compositing time will be noted on the field data sheets and/or in logbooks. Sample time listed on the COC record and sample bottle will be the time of the final sample composite portion.

Cleaning The sampling equipment and sample containers will be cleaned according to the equipment specifications or the analytical laboratory.

Glassware and plasticware cleaned at the analytical laboratory will implement the following procedure unless otherwise noted.

• Wash glassware and plasticware with phosphate-free detergent and rinse with tap water.

• Rinse with 10% hydrochloric acid (HCl).

• Rinse four times with deionized water.

B3. Sample Handling and Custody

Sample handling, preservation, and holding times will follow those approved by the USEPA in 40 CFR 136.3, as described in Standard Methods for the Examination of Water and Wastewater, 20th Edition, 1999, or most recent edition. Sample container, minimum sample volume, preservation, and maximum storage requirements for each parameter are listed in Table 1 below.

When samples are transferred to an outside contracted analytical laboratory, COC records will be completed. When samples are transferred between personnel, such transfer will be indicated on the form with signature, date, and time of transfer. The COC record will remain with the samples, sealed inside the cooler, until receipt by the contracted laboratory. Samples and sample containers will be maintained in a secure environment from the time the bottles leave the facility until the time the samples are received at the contracted laboratory. The contracted laboratory will maintain custody of bottles and samples using their normal custody procedures, as described in the QMP.

2. Sample preservation should be performed immediately upon collection. For composite chemical samples, each aliquot should be preserved at the time of collection. When use of an automated sampler makes it impossible to preserve each aliquot, then chemical samples may be preserved by maintaining at <6ºC until composite sample splitting is completed.

3. Sample should be analyzed as soon as possible after collection. The times listed are maximum times that samples may be held before analysis and still be considered valid. The term “analyze immediately” usually means within 15 minutes or less of sample collection.

4. Should only be used in presence of residual chlorine.

5. Perfluorinated compounds must be collected in strict conformance with laboratory guidance to avoid contamination with fluorinated materials such as Teflon, Tyvek, Gore-Tex, and blue gel ice.

B5. Quality Control

Field duplicate samples will be collected for analysis at a minimum frequency of ten percent.

Variation of duplicate values for each parameter must not exceed the range of precision and accuracy discussed in Section A.7, “Data Quality Objectives and Criteria for Measurement of Data,” and Table 2 above. Problems found with data collected are noted on the data sheets and in laboratory logbooks. The Project QA Officer or designee initials any changes to data.

The performance evaluation results are kept on file at the analytical laboratory and will be available for review by ADEC upon request.

B6. Instrument/Equipment Testing, Inspection and Maintenance

Before each sampling and analysis event, instruments and equipment to be used for field monitoring will be inspected prior to use. Testing instruments and equipment will be clean and in good working order before use in monitoring.

The routine maintenance for meters for measuring parameters designated as field tests will be conducted according to schedules and procedures described in manuals provided by the manufacturer and a maintenance log will be kept for each instrument.

A supply of replacement equipment and reagents is kept in the laboratory. This supply includes extras of commonly lost or broken equipment and enough reagents to perform scheduled analysis procedures for at least three months. Reagent stocks are rotated out every four to six months or according the manufacturer’s recommendation.

This information will be recorded on data sheets and in laboratory logbooks and will be available to ADEC for review upon request.

B7. Instrument/Equipment Calibration and Frequency

Field and laboratory instruments and equipment will be calibrated according to the manufacturers’ instructions. Records of calibration dates will be kept on calibration log sheets and will be available for review by ADEC upon request.

B8. Inspection/Acceptance of Supplies and Consumables

Chemicals will be checked for expiration date, sufficient quantity, and discoloration.

Equipment, meters, kits and supplies will be checked upon receipt by the QA Officer or designee to ensure that they are within technical specifications before use. Each reagent will be dated with the expiration date. Documentation including reagent expiration dates will be completed and kept on file in the laboratory. This form will be updated each time new or replacement equipment or reagents are received, and will be available to ADEC for review upon request.

B9. Non-Direct Measurements - Not Applicable

B10. Data Management

The data will be entered onto field data sheets and into laboratory logbooks and bench sheets.

The QA Officer or his designee will enter data into the DMR form after each monitoring event.

The following is a list of data information records that are kept available at the analytical laboratory for ADEC review upon request:

• Training records

• Field equipment and chemicals maintenance, cleaning and calibration records

• Field logbooks and/or field data sheets

• COC records

• Laboratory equipment and reagents maintenance, cleaning, and calibration records

• Laboratory bench sheets, control charts, and SOPs

• Records of QA/QC problems and corrective actions (field and/or laboratory)

• Laboratory data QC records

• Records of data review sheets

• Duplicate, split sample, performance evaluation records and other QA/QC control records (field and laboratory)

• Assessment records

• Data review, verification and validation records

Whenever possible data results will be entered electronically and transferred electronically to avoid transcription errors.

C. Assessment and Oversight

C1. Assessments and Response Actions

The QA Officer or designee will ensure that the field and laboratory forms are complete when checked for any errors. Approximately ten percent of the data sheets or logbook entries will be checked against the DMR entries. If errors are found, the QA Officer or designee will verify correct entry by comparing another ten percent of the sheets.

Should the sampling staff, laboratory personnel, QA Officer, or designee find errors in sampling or analysis, the QA Officer will notify the Project Manager and the party responsible for the error or deficiency, and will recommend methods of correcting the deficiency. The responsible party will then take action to correct the problem and will report corrections to the QA Officer and Project Manager. See above for how this information is recorded and reported.

The QA Officer or designee will monitor the field duplicate sampling and analysis activities and will review these results. The QA Officer will keep these assessment records available for review by ADEC.

Additionally, the facility and the analytical laboratory may be inspected and/or audited regularly by ADEC or USEPA.

C2. Reports to Management

The monitoring results are summarized on the DMR included in the permit and are submitted to ADEC after each event (an example DMR form is found in the appendices to the permit).

Assessment reports will be submitted by the Project QA Officer to the Project Manager as needed. Identified improvements to QA/QC will be implemented as necessary. Records of changes will be available for ADEC review. ADEC will be notified if changes/improvements require an amended QAPP.

D. Data Validation and Usability

D1. Data Review, Validation & Verification Requirements

The QA Officer will perform quality checks of data packages to detect correctable problems.

Problems noted will be immediately brought to the attention of the Project Manager. Items to be checked include data sheets, logbooks, data entry, DMRs, calibration logs, and COC records.

Questions to be considered during these quality checks include:

• Were correct methods used?

• Were holding times met?

• Were accuracy and precision within data quality objectives?

• Were reporting limits correct?

• Were lab qualifiers provided and explanations and corrective actions taken if there were anomalies in the data?

• Was the data package as a whole for each sampling event complete?

D2. Validation and Verification Methods

The QA Officer will check the accuracy and precision of data to ensure that data quality objectives are being met.

Data sheets and/or logbooks must be completely filled out and signed at the time of sampling and analysis. The QA Officer or designee will review data sheets and/or logbooks for accuracy, precision, missing or illegible information, errors in calculation, and values outside the expected range. Any questionable data will be brought to the attention of the field and/or laboratory personnel for resolution. The QA Officer will initial any changes made to the data, and any action taken as a result of the data review will be specifically recorded on the data sheet.

If data quality indicators do not meet specifications (see Section A7., “Data Quality Objectives and Criteria for Measurement of Data” and Table 2), the cause of the failure will be evaluated. If the cause is equipment failure, calibration and maintenance procedures will be reassessed and improved. If the problem is procedural error, the QA Officer will review methods used. If accuracy and precision goals are frequently not being met, QC procedures will be reviewed and, subject to ADEC approval, may be revised.

The QA Officer or his designee will review equipment maintenance logs, sample custody forms and equipment/supply inventory and inspection forms on a regular basis.

The verification of data accuracy will be made by the QA Officer during regular QC checks, replicate analysis, and split sampling checks. The QA Officer will make calculations and determinations for precision and completeness. The results of accuracy, precision, and completeness calculations will be kept on file at the laboratory.

D3. Reconciliation with User Requirements

The Project Manager and QA Officer will review the permit monitoring requirements on an annual basis. Problems with quality sampling and analysis will be discussed with ADEC to ensure that permit requirements and QAPP data quality objectives are met. Modifications to monitoring required by permit will require modifications to the approved QAPP.
