Monitoring Well Construction and Groundwater Quality Analysis at the U.S. Army Reserve Center Complex and Training Area, 84th Division, Milwaukee, Wisconsin.

摘要

The purpose of this field investigation was to determine geologic and hydrogeologic characteristics at the U.S. Army Reserve Center Complex and Training Center (U.S.A.R.C.) in Milwaukee, Wisconsin and to assess current ground water quality at this site. These objectives were accomplished by (1) reviewing existing monitoring data; (2) installing additional ground water monitoring wells; (3) collecting bimonthly water elevation data; and (4) performing two monthly ground water sampling events. This report presents information pertaining to ground water quality and documentation of well construction methods and ground water sampling protocols employed. Hydrogeologic and water chemistry data has been compiled to determine ground water contamination. Previous studies have shown that ground water has been impacted by chloride, arsenic, cadmium, iron, and volatile organic compounds. Enforcement standards have been exceeded for sulfate, dissolved iron, and volatile organic compounds. Groundwater elevation data obtained during this study has indicated that generally ground water flow within the shallow unconfined water table system is directed towards the south and southwest.
