Corona DWP: Safe, Reliable Drinking Water

Post Date:01/23/2020 11:30 AM

With concerns about the presence in some water supplies of a family of chemicals known as PFAS, the Corona Department of Water and Power (DWP) continues to ensure Corona has a safe and reliable drinking water supply.  

Two types of PFAS – Perfluorooctanoic acid (PFOA) and Perfluorooctane sulfonate (PFOS) – are the most commonly used, studied and regulated PFAS in the U.S. PFAS are a diverse family of manmade chemicals resistant to heat, water, and oil that have been used for decades in hundreds of industrial applications and consumer products such as carpeting, apparels, upholstery, food paper wrappings, fire-fighting foams and metal plating. PFAS have been found both in the environment and in blood samples of the general U.S. population.

The Department of Water and Power (DWP) is one of several local agencies that received a Monitoring Order in March 2019 from the California State Water Resources Control Board (SWRCB) Division of Drinking Water (DDW), requiring quarterly testing for per- and poly-fluoroalkyl substances (PFAS) in our drinking water wells. 

DWP’s water is safe to consume and meets all federal, state, and local regulations.

DWP has a diverse water supply, and a robust treatment and blending plan to ensure the water delivered to our customers is safe and reliable. Staff continue to treat and test to continually ensure safe drinking water.
