EPA testing for PFAS and lithium
EPA’s own nationwide testing (UCMR 5) found these in Spring Hill Water Dept’s water between Jan 2023 and Oct 2023. 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.
PFAS ("forever chemicals")
Found: PFOA (EPA testing)
What removes it: Reverse osmosis.
