Heal the Bay | 6,046 followers on LinkedIn. We’ve protected the Santa Monica Bay in Los Angeles County, California since 1985. | Our Mission: Heal the Bay is an environmental nonprofit making LA’s coastal waters and watersheds, including Santa Monica Bay, safe, healthy and clean. About Us: In 1985, a group of concerned citizens assembled to force the Hyperion Treatment Plant near El Segundo to maintain proper sewage treatment. Spurred by concern for public safety, the health of the Santa Monica Bay, and a belief that proper sewage treatment would be overlooked without an organization to keep tabs on the progress, this group of local residents joined forces and Heal the Bay was born.
