Montrose Chemical - Public Health Activities

Since the late 1980s, the California Department of Health Services (CDHS)--now the California Department of Public Health (CDPH)--has conducted health investigations of the Montrose Chemical Corporation Site and surrounding neighborhoods.

The site

The Montrose Chemical Corporation (Montrose) site is a former DDT manufacturing and formulation facility located in the City of Los Angeles. From facility operations that occurred from 1947 to 1982, DDT and other chemicals have migrated off-site via surface water runoff into drainage ditches and canals, and have been discharged to the sanitary sewer system, resulting in contamination of the Palos Verdes Shelf sediment and fish.  This chemical contamination has been the subject of a fish advisory and education for people who eat fish from the area. The DDT also went off-site via aerial deposition and as fill in the local neighborhood. DDT and other chemicals are also in the groundwater.

The Site Assessment Section (SAS) of CDPH has been involved with the community and agencies concerned about the Montrose Chemical Corporation and the Del Amo Superfund Site. SAS staff members have conducted a public health assessment, several health consultations, and exposure investigations, produced several fact sheets and conducted several community outreach education activities, and assisted the staff of the University of California at Irvine to provide individuals with environmental/clinical assessments. The U.S. Environmental Protection Agency is the lead agency overseeing the Montrose Chemical Corporation site.
