Description

Since 1991, Casco Bay Estuary Partnership (CBEP) has sponsored a monitoring program to track the concentrations of certain pollutants in sediments throughout Casco Bay to answer the following questions:

  • What are the concentrations of chemicals in Casco Bay sediments?
  • Are chemical concentrations in sediment high enough to harm marine life?
  • How have chemical concentrations in sediment in the Bay changed over time?

This fact sheet presents and interprets the results from sediment monitoring conducted from 1991 through 2011, the most recent year for which data are available. The sediment data show that concentrations for legacy pollutants tend to be declining throughout the Bay.
