Description:
An onsite evaluation was made of the capabilities of the U.S. Geological Survey Laboratory at Denver, Colorado. Particular emphasis was placed on determining their ability to meet the monitoring requirements connected with their contractual efforts with the U.S. Environmental Protection Agency. This monitoring is a major part of the Environmental Protection Agency's quality assurance program in support of energy-related activities in the western United States. Overall, water analyses for parameters related to the broad areas of chemistry, organics and pesticides, and radiochemistry are being conducted by approved sampling/preservation techniques and laboratory methods. Results on unknown performance samples and cross-check samples were well within acceptable ranges, thus documenting their ability to generate valid data. Specific recommendations for areas of improvement are given.
