California reached a second settlement with more than 70 parties to recover additional funding to contain a closed hazardous waste landfill threatening to release hazardous substances into the environment. The Vine Hill Complex, located in California’s Contra Costa County, operated as a hazardous waste treatment, storage and disposal facility until 1989, accepting offsite waste including petroleum industry byproducts, metals, electronic equipment, pharmaceuticals and paints, according to California Attorney General Rob Bonta in a complaint filed against the parties Thursday. … Despite its closure, Bonta says the Vine Hill Complex has released and threatens to release hazardous substances into the environment, including toxic substances detected in groundwater such as arsenic, lead, nickel, benzene and chloroform.
