Test Reactor Area (TRA-08), a groundwater monitoring well located approximately 1.5 miles south of the Advanced Test Reactor (ATR) Complex was drilled and constructed in 1990. The well is currently used as a groundwater monitoring compliance point for the ATR Complex Cold Waste Pond Industrial Wastewater Reuse Permit (IWRP). It is also used for Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) groundwater monitoring by CH2M-WG, Idaho (CWI). Over the life of the well, corrosion of the carbon steel casing has resulted in an accumulation of rust flakes in the bottom of the well thus adversely affecting the efficiency of the well. In addition, the water level in the well has dropped from a depth of approximately 477 feet below ground surface at the time the well was installed, to a depth of approximately 492 feet in 2009. The combination of the rust buildup on the bottom of the well and the falling water table has rendered the well essentially useless as a groundwater sampling location.
