Central Coast Long-term Environmental Assessment Network

CCLEAN is a long-term monitoring program that is designed to help municipal agencies and resource managers to protect the quality of nearshore marine waters in the Monterey Bay area. Begun in 2001, CCLEAN is determining the sources, amounts and effects of contaminants reaching nearshore waters. If the kinds and amounts of contaminants we measure are impairing nearshore waters, the information provided by CCLEAN will enable resource managers to implement corrective actions.
