Wood River Valley Aquifer System - Water-Quality Assessment

A component of groundwater availability is whether the water quality is suitable for a particular use. Elected officials, water managers, and the general public have raised concerns about whether water quality has been affected in developed and agricultural areas by wastewater disposal, fertilizer application, and animal waste.

Coeur d'Alene Lake Water Quality

The mining district in the South Fork Coeur d’Alene River valley was among the Nation’s largest producers of silver, lead, zinc, and other metals from the 1880s to the 1980s. These activities have produced large quantities of waste material that contain environmentally hazardous contaminants such as cadmium, lead, and zinc. Much of this material has been discharged directly to or washed into...
