Grand Teton National Park

I. Background

The Wyoming Department of Environmental Quality (WY DEQ) requires annual groundwater sampling of monitor wells in Grand Teton National Park (GRTE) and the John D. Rockefeller Memorial Parkway (JODR). This includes a Spring sample with analysis and a Fall sample and analysis. The purpose of the monitoring is to assess selected chemical and physical parameters of the groundwater surrounding wastewater treatment facilities in accordance with permit requirements.

II. Scope

The contractor shall perform groundwater monitoring in GRTE and JODR for the purpose of meeting the WY DEQ requirements. Sampling is required in the Spring and the Fall depending on the specific requirements for each well.

The contractor shall assure that all testing parameters are tested and recorded for each well according to the standards specified.

Contractor shall complete the State of Wyoming Class V (5E4) Package Plant Treatment (Ground Monitoring) Department of Environmental Quality Reporting Form for Class Injection Wells (otherwise known as GEMS (Graduated Environmental Management System) Reports). If the GEM Database is offline (as it has been since 2021), submit documents to WY DEQ using the WDEQ Water Quality Division Document Uploads Form.

The contractor shall provide their proposed methodology, quality control/assurance plan, and past experience with similar work with their quote. Also provide unit costs for sampling and/or analysis for additional wells.

This is a lump sum contract. As such, the contractor’s travel expenses and all other expenses associated with this project will not be reimbursed. An RV site may be made available for the contractor.

a. Task 1 – Annual Groundwater Sampling:

Removal of a minimum of three (3) casing volumes of water from the well should be completed prior to collecting a groundwater sample.

Minimum Purge Volume = 3 * ((Total Well Depth in feet – Depth to Water in feet) * Well Capacity)

Where Well Capacity (gallons per foot) is based on well diameter:

2 inch well = 0.163 6 inch well = 1.47 4 inch well = 0.653 8 inch well = 2.61

b. Task 2 – Colter Bay Landfill Groundwater Monitoring: See Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures | US EPA

7. Sampling methodology: A submerged pump is used for sampling most of the time, but a manual bailer is needed in the following cases: where there was less than 18-inches of water in wells, where wells are only accessible by walking in equipment, or where the water level was greater than 100 feet below surface. Contractor shall be prepared for necessitating both methods. The minimum well casing size is 2”.

8. Water levels fluctuate based on the year and time of year. See attached reports for what to expect for potential water levels.

9. Energy Laboratories is the park’s preferred laboratory, but an approved equal can be used.

10. The most recent reports for Task 1 – Annual Groundwater Monitoring and Task 2 – Colter Bay Landfill Groundwater Monitoring are included as Attachments 6 and 7, respectively.

11. All wells are accessible by vehicle or by short walk from vehicle. See Attachment 4.
