Results from the 2025 report
Each number is copied from the district’s report and links to the page it’s printed on. Where the report lists several plants, wells or purchased water, the highest is shown.

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 Purdue Univ. Water Works’s water between Feb 2023 and Aug 2023. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.
- PFHxS6.8 pptFound in 2 of 12 samples · highest resultNo federal limit in force for this one
- PFBS17.4 pptFound in 2 of 12 samples · highest resultNo federal limit in force for this one

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.

What removes it: Reverse osmosis.
Radium and uranium
