Water Quality


With the help of sophisticated, high-tech equipment, treatment partnerships, and a highly-trained professional team, JCSD ensures that our customers receive a regular supply of safe and high-quality drinking water.  Before any water reaches your home or business, it goes through a complex treatment process and undergoes regular testing to ensure that it meets or exceeds all state and federal drinking water quality regulations. 

JCSD publishes an Annual Water Quality Report (also known as Consumer Confidence Report or CCR) that contains the results of the water quality testing that took place during the year and is available the following year on or before July 1.

If you would like a copy of the CCR mailed to you or if you have any questions about the information in the CCR, please call JCSD’s Water Quality Department at (951) 685-7434 extension 104.

Information on PFAS

All untreated water contains varying levels of natural and man-made contaminants.  

From time to time, we may hear about contaminants in water that are affecting local, national and worldwide water quality, including recent stories on perfluoroalkyl and polyfluoroalkyl chemicals – also known as PFAS.  But what are these  chemicals and how did they get into our water? 

What are PFAS?

PFAS are prevalent in thousands of products we use every day, including non-stick cookware, firefighting foams, dental floss and stain resistant household coatings on carpets and upholstery.  It’s also found in our water; however, water agencies don’t put these chemicals into our water, but over time they have entered our waterways through manufacturing, landfills and wastewater discharge.

What’s Next?

The United States Environmental Protection Agency (USEPA) will set a maximum contaminant level by 2024.  The State of California is in the process of revising the Public Health Goal which will be published at an undetermined future date.  In addition, like many water agencies, we are studying long-term treatment options for this contaminant.

What does This Mean?

JCSD tap water meets or exceeds all USEPA and California regulations.  We take our commitment to provide safe drinking water with the utmost seriousness.  We are monitoring all upcoming regulations, as we always do, and will inform our residents of any developments.
