Perchlorate

One of the primary goals of the Santa Clara Valley Water District is to protect local groundwater resources. In 2003, an investigation performed under the direction of state water officials detected the chemical perchlorate in water wells in Morgan Hill, San Martin, and Gilroy. The Central Coast Regional Water Quality Control Board has regulatory oversight over the cleanup of the groundwater plume, which extends approximately ten miles. The district continues to work with the Regional Board and the local community to ensure the contamination is adequately addressed.

The Central Coast Regional Water Quality Control Board website contains the most current information on the Olin case, including monitoring reports, cleanup progress reports, and correspondence.
