Utility results describe the whole system, measured where water enters the pipes, not your tap. Your home’s plumbing can add lead or copper.

EPA testing for PFAS and lithium

EPA’s own nationwide testing (UCMR 5) found these in University of Kansas’s water between Oct 2024 and Jul 2025. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.

Lithium18.4 ppbFound in 3 of 4 samples · highest resultAbove EPA’s health reference level of 10 ppb (a guide, not a legal limit)

Source: EPA UCMR 5 occurrence data. The highest single result is shown; one high sample doesn’t mean every glass is that high.

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.
