A battery recycling plant in southeast Los Angeles County is one step nearer to turning into a Superfund web site after the U.S. Environmental Safety Company decided it accommodates sufficient hazardous waste to qualify and California officers welcomed federal help.
For almost a century, the previous Exide Applied sciences plant in Vernon melted down lead-acid automotive batteries, leaving as many as 10,000 properties coated in brain-damaging lead mud, in keeping with state environmental regulators.
Because the facility declared chapter, California has devoted $750 million and overseen the cleanup of greater than 5,000 lead-contaminated properties surrounding the Exide web site. However, during the last two years, a coalition of federal and state lawmakers, together with U.S. Sens. Alex Padilla and the late Dianne Feinstein, have referred to as for a Superfund designation in hopes that it’d herald federal funding that would assist expedite the cleanup or probably broaden its scope.
An EPA report revealed final week concluded that the Exide web site and surrounding communities meet the factors to be a Superfund web site — not for lead, however as a result of presence of one other poisonous chemical.
The Exide facility additionally launched trichloroethylene (TCE) — a identified human carcinogen — into the soil, in keeping with the EPA report. For many years, the extremely cell chemical has migrated deeper into the groundwater desk and into native aquifers tapped for ingesting water.
The Exide facility stands getting ready to Superfund standing as Yana Garcia, secretary of the California Environmental Safety Company, despatched a letter to the federal EPA expressing assist for a Superfund declaration on behalf of Gov. Gavin Newsom’s administration.
Exide is one in every of a number of industrial amenities which have contributed to intensive groundwater contamination in southeast L.A. County, which has ranges of TCE above federally established well being limits at a number of ingesting water wells. Though Exide’s groundwater monitoring had proven elevated TCE ranges for the reason that Nineteen Eighties, there had been no motion to take away or include the chemical plume till just lately.
“Whereas California has been cleansing up the world for a few years, impacts from the operations proceed to negatively have an effect on public well being,” Garcia stated within the letter. “Itemizing the previous Exide facility and surrounding areas would deliver important federal sources and experience to assist tackle poisonous ranges of lead the place Californians work, stay, and play.”
Exide saved TCE in a big open vat and used the chemical as a cooling agent to form molten metallic into bars. Traditionally, TCE was launched close to the southern portion of Exide’s Vernon advanced. It has seeped into the Exposition aquifer and is believed to be migrating southwest.
Environmental advocates concern that the contamination will seep deeper and have an effect on interconnected aquifers.
A minimum of 52 groundwater wells serving 300,000 individuals are inside 4 miles of the Exide web site. A number of groundwater wells have TCE ranges greater than federal ingesting water high quality limits. The very best readings have been discovered at a effectively, close to Converse and Gage avenues in unincorporated Florence-Firestone, the place water contained 140 micrograms of TCE per liter — 28 occasions greater than federal ingesting water restrict.
This has compelled water suppliers, together with Golden State Water Co., to dilute contaminated groundwater with floor water or set up costly water remedy techniques to take away TCE.
“Our clients don’t need to assume twice concerning the high quality of ingesting water coming from their faucets,” stated Daybreak White, a water high quality supervisor with Golden State Water Co. “Whereas the EPA report was not shared with Golden State Water, it is not uncommon for TCE or different contaminants to be present in water sources all through California. When they’re detected, water is handled to fulfill federal and state water ingesting requirements earlier than being delivered to clients.”
In shallow groundwater, TCE can reemerge as a vapor. The EPA report discovered vapors on the Exide grounds, though the constructing hasn’t been occupied since 2014. Two close by websites can also be liable for their very own TCE plumes.
Though water contamination was the idea for the EPA’s Superfund qualification, environmental advocates say they nonetheless need federal cash to go towards eradicating lead contamination. Testing by USC has proven excessive ranges of lead contamination past the 1.7-mile Exide cleanup zone that the state is engaged on.
“It’s clear there are main points with groundwater that have to be addressed,” stated Jane Williams, govt director of California Communities In opposition to Toxics. “However the soil contamination clearly extends outdoors the preliminary evaluation space, and somebody must go look there. We can’t abandon these folks.”

Padilla stated in a press release that he has requested the EPA to maneuver ahead with the Superfund designation and a “lengthy overdue cleanup.”
“The completion of the inspection report is a step in the precise route in attaining justice for the Southeast L.A. communities which have suffered the devastating penalties of Exide Applied sciences illegally dumping lead and different hazardous contaminants into the bottom and water provide,” he stated.
An organizer with East Yard Communities for Environmental Justice, mark! Lopez, stated the EPA ought to fund the cleanup of rail yards, which haven’t been cleaned and could also be closely contaminated with lead.
“The huge rail yards are the place the federal authorities needs to be coming in as a result of that’s the place we’re going to seek out the very best ranges of lead,” Lopez stated, noting their proximity to the Exide plant and to properties. “Each time the wind blows, it’s recontaminating our communities. They usually have explicit authority round rail that the state doesn’t.”
