US environmental regulators add more data to a proposed toxic waste site listing

The US environmental regulators are adding more information to their proposal to list the Exide Technologies-Vernon site in California on the National Priorities List. This new data concerns how groundwater is connected and where contaminants came from.

Listing a site on the National Priorities List means it becomes a Superfund site, making it eligible for federal cleanup funds. This additional data helps the regulators make a final decision on whether to add the site. If listed, the site will undergo a comprehensive cleanup paid for by the responsible parties or federal funds.
