Pico Water District Has Levels of Perfluorooctanoic Acid (PFOA) Above the Response Level
Our water system recently confirmed the detection of PFOA above the public-health-based Response Level
(RL). Although this is not an emergency, as our customers, you have a right to know what you should do, what
happened, and what we are doing to correct this situation.
We routinely monitor for the presence of drinking water contaminants. Water sample results received on
July 31, 2024, showed PFOA levels of 11.5 nanograms per liter (parts per trillion). This is above the State
Water Board-established response level of 10 nanograms per liter (ng/L) based on results of annual
average monitoring.
What should the customer do?
- You do not need to use an alternative water
supply (e.g., bottled water). - This is not an emergency. If it had been, you
would have been notified immediately. - This is not considered a high-concentration
exposure and therefore is not associated with
immediate health concerns. - Some people who drink water containing
PFOA over many years may experience
liver effects and may be at greater risk of
developing cancer. - If you have other health issues concerning the
consumption of this water, you may wish to
consult your doctor.
What happened? What is being done?
Board requiring the District to collect quarterly samples of four Per- and Polyfluoroalkyl Substances (PFAS)
with established notification levels and Response Levels. Historical results confirm that out of four PFAS, the
Perfluorooctanoic sulfonic acid (PFOA) was detected from the District’s wells above its established RL of 10 ng/L.
In anticipation that monitoring for PFAS could lead to levels detected which are above the RL, the District has
already begun work to construct three new treatment plants to address treatment (removal) of these chemicals
from the District’s wells. The District has purchased the new treatment systems and has approved an agreement
with a general contractor. Pending approval of an operating permit by State Water Resource Control Board
Department of Drinking Water, we anticipate having all three treatment sites installed and operational by
October 2024.
