Abstract : The Northwest Boundary Containment/Treatment System Operational Assessment described herein has been prepared to document and evaluate the performance related to the boundary system operations. This report covers the system operating period of FY89. Ground-water contamination problems have existed in the area of the Northwest boundary of Rocky Mountain Arsenal (RMA) since the mid 1950's, when investigations were conducted by the Army Corps of Engineers. In 1975, a ground-water surveillance program for RMA was established. This regional surveillance task included the monitoring of wells in the arsenal boundary areas. Since that time, several problem definition studies and design investigations have been conducted by RMA and the Corps of Engineers. Subsequently, a ground-water surveillance program was initiated in 1978 specifically for the Northwest boundary. As a result of the ground-water investigations in 1980, several contaminants including DIMP, DBCP, chloride, endrin and dieldrin were detected in a narrow plume of ground water leaving RMA to the north and northwest. Additional studies by RMA and the Corps of Engineers lead to the design and construction of the Northwest Boundary Containment/Treatment System (NWBS) that was completed in October 1984 (Figure 1). This was the third boundary ground-water contamination control system constructed and operated at RMA.
