Why is remediation needed at the RFS?

Industrial activities that occurred prior to UC ownership led to the majority of contamination found at the RFS. The three main pollutant sources were:

  1. The California Cap Company (the former site owner), which manufactured mercury fulminate for blasting caps from the 1870s to 1940s on what is now the RFS property.
  2. Stauffer Chemical Company, acquired by Zeneca Inc., which operated on property adjacent to the RFS from 1919-1962. Stauffer Chemical manufactured sulfuric acid, pesticides and other chemicals. This neighboring property is now owned by Cherokee-Simeon Ventures, LLC, also known as "CSV."
  3. An unknown source of polychlorinated biphenyls (PCBs)
