Results from the 2024 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. 3 numbers we weren’t sure about are held back until a person checks.

EPA testing for PFAS and lithium

EPA’s own nationwide testing (UCMR 5) found these in Park Ridge Water Dept’s water between Mar 2023 and Sep 2023. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.

PFOA17.2 pptFound in 12 of 26 samples · highest resultHighest sample is above the 14 ppt New Jersey limit. Compliance is judged on averages, not one sample.
PFOS14.1 pptFound in 8 of 26 samples · highest resultHighest sample is above the 13 ppt New Jersey limit. Compliance is judged on averages, not one sample.
PFHxS13.8 pptFound in 2 of 26 samples · highest resultNo federal limit in force for this one
PFNA8.1 pptFound in 1 of 26 samples · highest resultNo federal limit in force for this one
PFBS5.1 pptFound in 5 of 26 samples · highest resultNo federal limit in force for this one
Lithium21.1 ppbFound in 7 of 26 samples · highest resultAbove EPA’s health reference level of 10 ppb (a guide, not a legal limit)

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.
