These provisions are to be read and interpreted in conjunction with the provisions of the contract specified above.

I. Project Description:

This project serves to provide technical support of activities at the California Gulch Superfund Site. The activities will include support services for monitoring and assessing groundwater conditions across CalGulch.

Placer gold was discovered in the California Gulch area in 1860. Subsequent discovery of silver bearing lead carbonate ore initiated over 100 years of heavy industrial mining, mineral processing and smelting. Acidic, metal laden water from the historically mined area flows through the shallow groundwater and down

California Gulch approximately six miles to its confluence with the Arkansas River.

The California Gulch was placed on the National Priorities List (Superfund) in 1983. The California Gulch

Superfund Site (“CalGulch”) encompasses about 18 square miles in and around Leadville, in Lake County, Colorado, at an elevation of about 10,000 feet. The United States Environmental Protection Agency (EPA) is the lead agency for CalGulch and the Colorado Department of Public Health and Environment (CDPHE) is the cooperating agency. Colorado Mountain College’s Natural Resource Management Program provides field and logistical services to both the EPA and CDPHE.

CalGulch was divided into 12 Operable Units. Additional work of this project is to provide recommendations for the improvement of the monitoring program and for Operable Units to maintain effectiveness. The majority of the Record of Decision mandated activities have been completed at CalGulch. The Record of

Decision is a publicly accessible document.
