Description Sediment cores were collected from Lake Washington, Lacamas Lake, and Offutt Lake as part of a long-term study evaluating contaminant trends across the state. Contaminant analyses for the 2008 sampling period included mercury, lead, and polycyclic aromatic hydrocarbons (PAHs).

Overlying contaminant trends for each core varied by lake and analyte. Lake Washington has received higher contaminant loads than Lacamas Lake or Offutt Lake. However, concentrations of mercury and lead at all three lakes were found within expected concentrations based on previous Washington State sediment core studies.
