Executive Summary The Groundwater Monitoring Improvements Plan identifies active research and support facilities that

have the potential to impact groundwater quality, and establish a basis for an expanded groundwater monitoring program. The evaluation process focused on facilities which have inventories of hazardous or radioactive materials which could create groundwater contamination problems if there were leaks in piping systems or tanks, or whose operations create the potential for groundwater contamination by the direct activation of soils. Areas Requiring Improved Groundwater Monitoring Programs The Groundwater Monitoring Improvements Plan provides: 1) an overview of the operational history of each facility requiring improvements in its groundwater monitoring program; 2) the identification of potential contaminant source areas (i.e., underground storage tanks, beam stop areas, etc.); 3) a review of the historical and current groundwater monitoring program and available groundwater data; 4) recommendations for necessary groundwater monitoring upgrades or improvements at each facility; and, 5) a prioritized schedule for the installation of new wells. The facilities that require improvements to their groundwater monitoring programs include: th
