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 City of Irving’s water between Jul 2023 and Apr 2024. These are EPA lab results, separate from the district’s report. Anything not listed was not detected.
- PFOA4.9 pptFound in 4 of 12 samples · highest resultAbove the federal limit that takes effect in 2029 (4 ppt)
- PFOS4 pptFound in 1 of 12 samples · highest resultBelow the federal limit that takes effect in 2029 (4 ppt)
- PFHxS3 pptFound in 1 of 12 samples · highest resultNo federal limit in force for this one
- PFBS5.6 pptFound in 12 of 12 samples · highest resultNo federal limit in force for this one
- Lithium9.99 ppbFound in 5 of 12 samples · highest resultBelow EPA’s health reference level of 10 ppb

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.
