Lead and Copper Monitoring

Fontana Water Company has been monitoring lead and copper concentrations at customer taps throughout its distribution system to comply with the Lead and Copper Rule (“LCR”) since the late 1990s.  The LCR is a federal regulation enforced by the California State Water Resources Control Board, Division of Drinking Water which requires water providers collect lead and copper samples from customer taps every three years.  If lead concentrations exceed an action level of 15 parts per billion or copper concentrations exceed an action level of 1.3 parts per million in more than 10% of customer taps sampled, the system must undertake a number of additional actions to control corrosion.

Fontana Water Company has not exceeded the 10% action level in any of its lead and copper monitoring events since the promulgation of the LCR.  The last lead and copper monitoring event completed by Fontana Water Company was in September 2018.  Laboratory results show that 100% of the samples were below the lead and copper action levels.  The next monitoring event will commence in calendar year 2021.

Fontana Water Company utilizes groundwater, local surface water from Lytle Creek, and imported water from the State Water Project as its sources and are generally noncorrosive and high quality.  Fontana Water Company uses only the highest quality materials and components to construct and maintain the water system, which meets strict federal and state regulations.  Fontana Water Company continues to work tirelessly to provide its customers with high quality drinking water that is safe and aesthetically pleasing.
