If you ask the earlier Baby Boomer generation about DDT (dichlorodiphenyltrichloroethane), they might recall images of this chemical being sprayed in their neighborhoods right where they were playing. DDT was first considered a wonder chemical by many for its use against disease-carrying insects and agricultural pests, prompting a Nobel Prize for its discovery. DDT was widely used as a pesticide beginning in the 1940s, until concerned biologists led by Rachel Carson, documented its harmful effects on birds, other wildlife, and possibly human health. Another trait of DDT is that once released, it stays in the environment for a very long time. The U.S. Environmental Protection Agency (EPA) finally banned its use in 1972. However, releases of this chemical were widespread by the time it was banned.
The story in southern California, however, is a little different. A DDT manufacturing company called the Montrose Chemical Corporation, located in Torrance, Calif., had a permit to release their DDT waste through an outfall pipe that led to the ocean nearby. Other factories in the area were manufacturing PCBs, another harmful chemical, and releasing their waste through the same outfall pipe at White Point.
Millions of pounds* later, local and federal governments determined that the release of these chemicals was a violation of the Comprehensive Environmental Response Compensation Liability Act (CERCLA), which is also known as Superfund. After 10 years of litigation and data collection, a settlement agreement was reached, and funds were made available to clean up the contamination site at the bottom of the ocean along Palos Verdes Shelf and to restore resources harmed from the pollution within the Southern California Bight.
One year after a settlement was reached, in 2001, the Montrose Settlements Restoration Program (MSRP) was formed to oversee restoration of resources harmed by DDT and PCBs including Bald Eagles, Peregrine Falcons, seabirds, fishing, and fish habitat. This year marks the 10 year anniversary for the restoration program, and there is plenty to celebrate. At www.montroserestoration.noaa.gov, you can find the program’s restoration accomplishments, photos, wildlife webcams, and the latest updates from the program’s trustee council. Relive some highlights of successful restoration milestones of the program over the last decade, and see what projects MSRP is proposing in the Draft Phase 2 Restoration Plan released for public comment this month.
A larger symbol of the hope for recovery here manifests itself in the film Return Flight: Restoring the Bald Eagle to the Channel Islands, directed by the Filmmakers Collaborative SF. This film captures the spirit of biologists, partners, volunteers, and concerned citizens working to secure a biological legacy for the Bald Eagle in southern California despite the chemical legacy of DDT.
