BGNDRF PFAS ANALYSIS

STATEMENT OF WORK

BRACKISH GROUNDWATER NATIONAL DESALINATION RESEARCH FACILITY

PFAS ANALYSIS

1. GENERAL INFORMATION

There are three objectives for the water analysis described in this Statement of Work. The first objective is to give the clients of the Brackish Groundwater National Desalination Research Facility (BGNDRF) thorough information concerning well water for the purposes of designing and configuring pilot scale water treatment technologies and measuring technology performance.

The second objective is to meet reporting requirements under the New Mexico Environment Department (NMED) discharge permit, DP-1472 for concentrate in the BGNDRF evaporation ponds. NMED monitors potential groundwater contaminates discharged at this facility.

The third objective is to allow BGNDRF to monitor the performance of its per-and polyfluoroalkyl substances (PFAS) removal equipment and research systems.

1.1 SCOPE OF WORK. The Contractor shall provide all personnel, equipment, tools, materials, supervision and other items and services necessary to perform analysis of water and concentrate as described in this statement of work. Samples of water will come from a variety of sources including four brackish water wells, desalination concentrate, and evaporation ponds. There may be occasional solids testing as well. The Contractor shall perform to the standards in this contract. Samples will be sent intermittently and will generally include 1-10 samples and 1-3 field blanks. Sample frequency will range from weekly to monthly and are dependent upon BGNDRF operations. The minimum set of PFAS analyses are listed in Exhibit 1, however, if more compounds can be provided at a reasonable cost, it could be acceptable.

1.2 CONTRACTOR AND LABORATORY STANDARDS

1.2.1 Contractor’s employees performing analysis must have current and valid certifications in the analysis methods required under this contract. Proof of these certifications shall be submitted to the Contracting Officer prior to starting work under this contract.

1.2.2 Laboratory shall be accredited in accordance with the most recent National Environmental Laboratory Accreditation Conference (NELAC) standards for water analysis and certified by the state in which it is located. The laboratory must be in good standing with both, and not be under review or investigation. The Contractor must be participating in the EPA Quality Assurance Program. The Contractor will submit proof of laboratory certification and applicable quality assurance (QA) sample results prior to starting work under this contract.

1.2.3 Laboratory shall provide method detection limits and reporting limits for the requested PFAS compounds, as well as others that may be part of a larger data set.

2. GOVERNMENT–FURNISHED PROPERTY AND SERVICES

2.1 The Government will obtain samples of the water from its wells, evaporation ponds, and treatment equipment using containers and procedures provided by the Contractor.

2.1.1 Procedures will include minimum well run times prior to sampling water from each well.

2.2 The Government will ship the water samples to the Contractor using the chain of custody protocol and forms provided by the Contractor.

2.3 The Government will provide existing Excel spreadsheets of well water and evaporation pond concentrate test data for the Contractor to insert the newly acquired data described in this Statement of Work.

3. CONTRACTOR-FURNISHED ITEMS AND SERVICES

3.1 The Contractor shall provide clean sample containers (e.g., free of debris and residue, acid-washed, etc.), PFAS-free water for field blanks (as requested), and coolers, and arrange delivery of these containers via courier. Sample containers will contain applicable preservatives. If preservatives are needed, the preference is to have the preservative in separate sealed containers rather than being placed inside the sample containers (leaks have occurred in the past). Contractor shall also provide chain of custody forms and any other necessary processing documents. The Contractor must deliver the containers and necessary documents to the Brackish Groundwater National Desalination Research Facility at 500 La Velle Road, Alamogordo, NM 88310 within 14 calendar days after receipt of the Notice to Proceed, unless other arrangements are made.

The Contractor will provide the BGNDRF Facility Manager with instructions regarding how to sample, pack and ship the samples to the Contractor and any time limits that must be observed between the time of sampling and reception by the Contractor. Instructions will include chain of custody procedures.

4. DELIVERABLES

4.1 REPORTS

4.1.1 Well water, evaporation pond, and equipment monitoring test results will be reported together in one report.

4.1.1.1 Contractor shall provide an electronic report after each test cycle. Each report will be comprised of a written narrative of detection highlights, observations, and analyses. Graphs including comparisons to historical data shall be included. Sample reports from previous vendors can be provided upon request.

The narrative will be accompanied by a spreadsheet containing test data from 2022 through the present cycle of testing. The laboratory results shall be included along with a Level 2 or better report. Summarize any QC flags and describe any issues related to problems with analyses.

4.1.2.2 The written narrative will generally be no more than one or two pages in length. It will be Microsoft Word compatible.

4.1.2.3 Contractor shall provide an updated electronic Microsoft Excel spreadsheet of water test data after each complete cycle of testing. The spreadsheet data for each test cycle shall be added to existing data from prior years of testing. The data will be inserted chronologically, for ease of side-by-side comparisons of data. The spreadsheet shall include a key for QC flags and maintain formatting for QC, omitted analyses, and other items as provided in original spreadsheet.

5. SCHEDULE

5.1 The period of performance is for 12 months (September 1, 2022, to August 31, 2023).

5.2 NMED Report Samples

5.2.1. If samples are sent for analysis for NMED reports, analyses must be completed in time for BGNDRF to complete its report. NMED requires a semi-annual report from BGNDRF in accordance with discharge permit DP-1472. In order to meet NMED reporting requirements, the Contractor’s final report from testing of evaporation pond and irrigation concentrate must be completed by the following dates each year: December 31st and July 1st of each year.

5.3 Most sampling events will occur intermittently throughout the year and with advance notice as required by the analytical laboratory.

5.4 We request a standard turnaround time (TAT) of no more than 15 business days, with a preference towards 10 business days.

5.5 Contractor for each test cycle shall coordinate with the BGNDRF Facility Manager regarding the sampling date and shipping date for shipping samples to the Contractor’s laboratory. The Contractor shall provide the Government sampling containers, sampling protocols, shipping containers, and chain of custody forms within 5 days of scheduled sampling date. Contractor will arrange and pay for shipping.

Contractor will begin analysis of samples within 3 days after receipt of such samples. Upon receipt of samples, the Contractor shall complete analysis and submit required deliverables within 20 calendar days.

Exhibit 1: Minimum Suite of Water Tests

Note: The most current method for performing the following tests will be used. There are thousands of PFAS compounds, and it is recognized that each lab may have its own suite of PFAS chemicals for a given price. Below are the minimum requested PFAS compounds. As of 2022, BGNDRF has used EPA 537MOD, however other methods with similar or better detection limits may be acceptable so long as they are accepted by the EPA, DOD, or other similar bodies.
