Utility results describe the whole system, measured where water enters the pipes, not your tap. Your home’s plumbing can add lead or copper. 1 number we weren’t sure about is held back until a person checks.
EPA testing for PFAS and lithium
EPA’s own nationwide testing (UCMR 5) found these in Glassboro Water Department’s water between Nov 2024 and Aug 2025. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.
- PFOA9.4 pptFound in 4 of 12 samples · highest resultAbove the federal limit that takes effect in 2029 (4 ppt)
- PFOS6.6 pptFound in 4 of 12 samples · highest resultAbove the federal limit that takes effect in 2029 (4 ppt)
- PFHxS3.4 pptFound in 1 of 12 samples · highest resultNo federal limit in force for this one
- PFBS3.3 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.
