The Southern Historic Stormwater Pathway—also called ‘‘Operable Unit 6’’ (OU6) or the “Southern Pathway”—is part of the Montrose Superfund cleanup site in Los Angeles County, Calif. From the 1940s to 1960s stormwater with the chemical DDT and other chemicals from the Montrose facility traveled through ditches and swampy areas to the Dominguez Channel. In the 1960s, this pathway was covered with dirt, which prevented people from contacting it.

Today, the land above where the pathway was covered includes part of the former “ECI Property” on Torrance Blvd. and an area with 34 homes west of S. Vermont Ave.

On March 12, 2021, the U.S. government sent a settlement between EPA and the Montrose Chemical Corp to federal court for approval. If approved, Montrose, under EPA oversight, will study the land above the pathway to see if there are any human or ecological risks.

EPA will share updates and information on this website as work on this pathway continues
