CHICO LOCATION
Storm water refers to the rainwater that drains off a municipal or industrial site during a rainstorm into various types of receiving waters, such as lakes, rivers, or irrigation ditches. In California, the Water Quality Control Board has jurisdiction over storm water regulation and enforcement. Information is being collected to determine the type and extent of contamination from storm water runoff, with the intent to establish units to mitigate potential environmental contamination.
