SITE BACKGROUND

The 8,000-acre New Idria Mercury Mine site is located in and near the abandoned town of Idria, California. The mine operated from 1854 to the early 1970s. Mining activities contaminated surface water, groundwater, sediments and wetlands with metals, including mercury. Site studies of the contamination are ongoing.
