Cal Water’s Leadership on PFAS
There have been quite a few recent news reports about per- and polyfluoroalkyl substances (broadly referred to as PFAS) and how they affect water quality. With all of the attention, we wanted to provide additional background information about PFAS and, more importantly, what we at Cal Water are doing to help protect our customers’ health and safety.
What is PFAS?
PFAS are manmade compounds that have been used to make carpets, clothing, fabrics for furniture, paper packaging for food, and other materials (e.g., cookware) that are resistant to water, grease, or stains. They are also used for firefighting at airfields, which is one way they found their way into the groundwater in some areas.
Cal Water’s Commitment to Protecting Health & Safety
Protecting our customers’ health and safety is our absolute highest priority. Through our rigorous water quality assurance program, we work to ensure that the drinking water we deliver to our customers complies with all state and federal water quality standards.
Monitoring & Testing for PFAS
Cal Water has been monitoring and testing for a number of PFAS, and has tested our active water sources in the state. Years ago, we already shared our test results with regulators at the state and federal level to help them gain a better understanding of the how PFAS has impacted water supplies.
In a small percentage of cases, we needed to take additional steps to help protect our customers. From removing water supply sources from service to constructing new water treatment facilities, we have worked diligently to ensure the safety of the drinking water we provide to our customers. We will continue implementing a rigorous testing and monitoring regimen, and taking action where needed to protect the health and safety of our customers.
Holding Polluters Responsible
Safeguarding our customers also means protecting them against having to pay to clean up pollution. To this end, Cal Water has filed a lawsuit against a group of companies that manufactured and sold firefighting foam products that released PFAS into the environment, to have the responsible parties—not our customers—bear the costs of making sure the water is safe to drink.
Pursuing a Comprehensive Solution
A comprehensive solution is needed to effectively address the public health concerns regarding PFAS. That is why Cal Water is strongly supporting transparent and decisive action by both the state and federal governments. For example, we have:
- Encouraged the U.S. Environmental Protection Agency to establish a national primary drinking water regulation for PFOS and PFOA, two of the more common members of the PFAS family.
- Voiced our strong support for California Senate Bills 1044 and 1817, which will help protect the State’s drinking water supplies against contamination by prohibiting the sale and use of certain products that contain PFAS.
- Urged the California Legislature to pass State Senators Portantino and Gonzalez’s Senate Bill 1056, which will help residents better understand the full extent of PFAS contamination by requiring the certification of accurate methods to test for PFAS based on the best available science.
- Strongly supported California State Senator Ben Allen and Assembly Member Richard Bloom’s Bill 2247 to establish a publicly accessible database that houses the sources of PFAS entering water supplies.
Together, these steps will not only address a growing public health concern over PFAS, but also help reassure communities about the safety of their drinking water.
Conclusion
We want our customers to know as much as possible about their local water supply and our continuous efforts to ensure safe drinking water. Water quality reports for all our districts are available to the public and can be accessed online.
