June 6, 2008 - Lake Coeur d'Alene Safe for Swimming

Hayden Idaho -- Based on water quality tests by the Idaho Department of Environmental Quality (DEQ), the Panhandle Health District (PHD) has determined that Lake Coeur d'Alene is safe for swimming after recent flooding.

"We've consulted with DEQ and determined that there's not a health risk to swimmers," said Dick Martindale, PHD's Environmental Health program manager.

DEQ tested water quality twice at locations near Sanders Beach, Coeur d'Alene City Beach and the center of the lake. Concentrations of lead and cadmium were below the level of concern for drinking water, therefore primary contact activities such as swimming should not be a concern. Levels of E.coli, naturally occurring bacteria, were below the level of concern for swimming. DEQ also compiled test data from six regulated public water systems that draw water from Lake Coeur d'Alene and determined that their treated water is safe for drinking.

DEQ and PHD advise people on non-regulated water systems and individuals/families that draw water from the lake for private use always to properly filter and disinfect the water before using it. Water treatment specialists and water service providers in the community can provide the public with detailed instructions.

Consistent results from the testing indicate no additional flood-related water quality monitoring is necessary. "With amounts below the level of concern, we don't see a need to continue sampling," said Tom Herron, DEQ's Regional Water Quality program manager.

A fish consumption advisory the Idaho Dept. of Health and Welfare issued in 2002 remains unchanged. Consumption limits were set after samples showed levels of lead, mercury and arsenic that could affect health.
