Description Ground water samples were collected from four domestic water supply wells located near the former Toftdahl Drum Site on April 6, 1993. This sampling was part of the routine ground water monitoring conducted at the site since 1987. Low concentrations of copper and zinc were detected in the domestic wells. These concentrations were all well below state and federal drinking water standards and state ground water quality standards. Observed concentrations are consistent with previous sampling results; copper and zinc are the only analytes that are regularly detected in the private wells. These occurrences are probably related to well construction and plumbing materials.
