EPA testing for PFAS and lithium
EPA’s own nationwide testing (UCMR 5) found these in Citrus Heights Water District’s water between Jan 2024 and Apr 2025. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.

What you can do
Nothing here is an emergency notice: if the district has a violation, it must tell customers directly. If you’d like to lower these at your tap, these are the treatments that remove them, and the catalog shows the models certified for each. Ranking is by certified removal; commissions never change the order.
