Protecting Water Quality in the Santa Clarita Valley

SCV Water’s top priority is providing safe, reliable water that meets or surpasses all state and federal drinking water health and safety standards. We are keeping our water supply safe by addressing public and environmental effects of hazardous substances in our local groundwater aquifers.

California Department of Toxic Substances Control

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, was enacted by Congress on December 11, 1980. This law created a tax on the chemical and petroleum industries and provided broad Federal authority to respond directly to releases or threatened releases of hazardous substances that may endanger public health or the environment. 

What is EE/CA?

Engineering evaluation/Cost Analysis (EE/CA) is prepared for removal actions. An EE/CA uses environmental information such as sampling, monitoring, and survey data that provides details on the nature and extent of contamination and describes removal action alternatives to address the contamination. An EE/CA evaluates the effectiveness, implementability, and cost of each alternative identified and recommends a preferred alternative.
