Description Ecology’s Toxics, Compliance, and Ground Water Investigations Section collected samples from four domestic water supply wells located in the area surrounding the former Toftdahl Drum Site on April 23, 1991. This sampling was part of the routine ground water monitoring conducted at the site since 1987. Low concentrations of lead, 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.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
