Description Washington State Department of Ecology scientists collect three sediment cores every year to study how chemicals have built up in the environment over time. We choose three new lakes every year in different parts of the state, targeting water bodies based on the chemicals we are measuring. Age-date data and chemical concentrations from sediment profiles can help us understand how chemical levels change over time. For 2024, we are focusing on polychlorinated biphenyls (PCBs). These synthetic industrial and commercial compounds persist in the environment, bioaccumulate, and can cause adverse health effects.

This summer, we are collecting sediment cores from:

• Bead Lake (Pend Oreille County)
• Lake Goodwin (Snohomish County)
• Lake Sawyer (King County)

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.
