 EVMWD is Committed to Providing Customers with High-quality Water that Meets or Exceeds all State and Federal Standards for PFAS

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other potentially harmful chemicals. EVMWD is proactively conducting well testing to ensure water meets the Department of Drinking Water’s interim notification levels for PFAS.


What Are PFAS?

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals, including PFOA, PFOS and GenX, which is a chemical replacement for PFOA. For more than 70 years, PFAS have been manufactured and used in variety of industries worldwide. 
According to the Environmental Protection Agency (EPA), exposure to certain PFAS can lead to adverse health effects in humans. 

Where Are PFAS Found?

PFAS are man-made contaminants that are found in thousands of products that are used daily, including our shampoo, clothing, cleaning products, food wrappers, non-stick cookware, firefighting foam and carpet.  

Most people worldwide have measurable amounts of PFAS in their blood and are typically exposed to PFAS through eating food grown in contaminated water/soil or consuming food from packaging that contains PFAS; breathing air with dust particles from contaminated soil, upholstery, clothing; inhaling fabric sprays containing PFAS; or drinking contaminated water.

How Did PFAS Get Into Our Water?
Like many communities throughout the nation, tiny amounts of PFAS are found in our water supply. Water districts, like EVMWD, don’t put these chemicals into water, but over time they have entered our waterways through manufacturing, landfills and wastewater effluent. 

What is EVMWD Doing to Treat and Remove PFAS?
Our customers are our top priority, and EVMWD is closely monitoring PFAS in our water supply. Our water is thoroughly treated and tested thousands of times per year to ensure it meets some of the highest water quality standards in the world. If PFAs are discovered at a reportable level, EVMWD will take immediate and appropriate actions to ensure water meets state and federal regulations.  We also make sure to notify our customers along with the appropriate state and federal officials.
