Technical Report · Fri Sep 25 00:00:00 EDT 1987

OSTI ID:6830096

The Twin Cities Army Ammunition Plant (TCAAP) is located north of the Twin Cities of Minneapolis/St. Paul, Minnesota and comprises the northern edge of the New Brighton/Arden Hills/St. Anthony (NBAHSA) Superfund NPL site. The U.S. Army estimates aproximately 26 pounds per day of VOC contaminants are migrating off TCAAP into the ground water at the southwest boundary of TCAAP. This contamination is migrating in both the Hillside Sand Aquifer and the deeper Prairie du Chien/Jordan Aquifer (both are aquifers that supply water to the cities of New Brighton and St. Anthony). The primary contaminants of concern affecting the ground water include: PCBs, benzene, toluene, TCE, VOCs, arsenic, chromium, lead, and metals. The selected remedial action for this site includes: operation of a six-well system to extract ground water migrating from the southwest corner of TCAAP and treatment with air stripping.
