Water Quality Analyses and Phytoplankton Enumeration at LRAFB 2022

The purpose of this SOW is to assess water quality and phytoplankton species diversity and density in two
recreational lakes at Little Rock AFB. Monitoring the ecological conditions in these waterbodies is
important to ensure their continued quality not only for wildlife habitat, but also for recreational fisheries.
Data from the laboratory analyses described below will be used to inform decisions made by the base
natural resource management program to manage the lakes.

1. General:

1.1 This statement of work (SOW) is being submitted by the Arkansas Ecological Services Field Office,
110 South Amity Rd STE 300, Conway, AR 72032 to support annual water quality sampling
occurring at Little Rock Air Force Base (AFB), Jacksonville, AR 72099. The purpose of this SOW
is to acquire laboratory analyses of water samples for a variety of measures detailed in section

1.2 This SOW provides the details of work to be performed in support of Little Rock AFB and the Air
Force Civil Engineer Center (AFCEC). The Air Force is engaging the FWS cooperative agreements
as a Sikes Act CA, to enable a cost-effective, time-efficient, and flexible means of achieving Air Force
Integrated Natural Resources Management Plan (INRMP) goals and objectives. The Sikes Act allows
the DOD to obtain natural resources management assistance employing Interagency and Cooperative
Agreements; orders with other federal agencies; 18-month obligation periods; and without most
acquisition regulations.

1.3 The selected laboratory should have experience in analyzing water samples for common nutrients and
pesticides as well as the ability to identify and enumerate phytoplankton species present in the samples.
The laboratory is expected to adhere to approved EPA methods and American Society for Test and
Material standards. Additionally, the lab is responsible for providing all sample bottles and shipping
materials and any necessary preservatives, quality assurance protocols, and shipping materials and
costs, if applicable.

2. Place of Performance and Period of Performance

2.1 Water samples will be collected at Little Rock AFB, 1500 Vandenberg Blvd, Jacksonville, AR 72099.

2.2 Water samples will be collected and delivered to the laboratory once per month in April, May, June,
July, August, September, and October 2022. The exact dates depend on the availability of FWS field
biologists and weather conditions.

2.3 Normal duty hours Monday thru Friday 8:00 a.m. - 4:30 p.m. In the event of emergencies, Contractor

shall provide contact information.

2.4 Non-duty hours include weeknights, weekends, and Government holidays (New Year’s Day, Martin
Luther King JR. s’s Birthday, Memorial Day, Independence Day, Labor Day, Columbus Day,
Veteran’s Day, Thanksgiving Day, Christmas Day).

3. Scope:

3.1 Local FWS biologists will collect water samples once monthly at two waterbodies at Little Rock AFB
(site names: BBL, LBL) between April and October 2022. A Van Dorn sampler will be used to collect

water samples from about half-way through the epilimnion of each waterbody. One sample will be
collected from each waterbody, totaling 2 samples collected per month and 14 overall. Following each
collection date, the samples shall be shipped overnight on ice to a laboratory outside local commuting
distance if appropriate quality assurance measures are in place. Using a local laboratory will allow the
field biologists to deliver the samples in person, eliminating shipping concerns that may delay samples
from arriving within specified times to adhere to quality assurance measures. Ideally, one laboratory
will be able to conduct both water quality analyses and phytoplankton enumeration to reduce shipping
costs and associated carbon footprint.

Upon receipt of the samples, the selected laboratory shall analyze each of the 2 samples collected per
month from each site with 14 overall samples for: dissolved nitrite (NO2-), dissolved nitrate (NO3-),
dissolved orthophosphate (PO4), total nitrogen (N), total phosphorus (P), total ammonia nitrogen
(TAN), and chlorophyll α concentrations. Additionally, samples shall be analyzed for common
pesticide concentrations, including organochlorines, PAHs, PCBs, and phytoplankton but only one
sample will be collected from each waterbody, totaling 2 samples collected per June, August, and
October with 6 samples overall. Additionally, phytoplankton in each water sample shall be identified
(to species when possible) and counted using appropriate methodologies.

4. Deliverables and/or Delivery Schedule:

4.1 For water quality analyses, deliverable will be a written report from the laboratory listing the
concentrations of each analyte measured in each sample. For phytoplankton enumerations,
deliverable will be a written report from the laboratory identifying the phytoplankton species and
quantifying their biovolumes in each sample. Reports are due within 30 days after each sample date
(i.e., one report will be expected monthly from May – November 2022).

4.2 Reports will be electronic documents (e.g., Microsoft Word or Excel document, PDF, etc.) delivered

via email to .

5. Evaluation and Acceptance

5.1 The Contractor shall adhere to approved EPA methods and American Society for Test and Material
standards for analyses and provide information regarding methods used, if requested. The Contractor
shall comply with the work schedule detailed in 4.1. If unable to meet a required deadline, the
Contractor shall contact the Technical Coordinator to identify a solution. Final Government
acceptance and payment shall be held until the final report is received and approved by the Technical
