Summary

PFAS above the 2024 federal limits. Systems have until 2029 to meet the PFAS limits.

Is it an emergency? No: PFAS limits are about years of exposure, not a glass of water, and nothing in EPA's data calls for you to stop drinking the water today. If your utility ever issues a boil-water or do-not-drink notice, follow it.

PFAS
Above limitPFOS above the federal limit in EPA's 2023–2025 testing (PFOS 7.3 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
Lithium
Above screening levelHighest result 30.9 ppb. EPA uses 10 ppb to decide what to study further. It is not a health limit, and there is no federal limit for lithium. About 1 in 4 systems tested were above it.
Lead
Below action level1.98 ppb (parts per billion) at the 90th percentile: 9 in 10 homes sampled were at or below it. Action level 15 ppb, falling to 10 ppb in Nov 2027. Monitoring period ending Dec 2025. Your home's pipes can make yours higher.

What you can do
  • Pregnant, or mixing baby formula with tap water? Babies drink more water for their size, so PFAS exposure matters more for them. Consider bottled water or a filter certified for PFAS for formula, and ask your doctor. Health effects.
  • To lower your PFAS exposure now, a home filter certified for PFAS reduction works (reverse osmosis, or activated carbon certified to NSF/ANSI 53 or 58). Filters for these results.
  • Built before 1986, or not sure what your service line is made of? Check your service line and test your tap. Utility data can't show your pipes.
  • Tested your own tap? Compare your result with these numbers. Moving? Compare this system with another.
  • Read City of Grand Island's annual water quality report (Consumer Confidence Report). It lists every regulated contaminant tested and is usually on the utility's website or mailed with your bill, and you can also request it at (308) 385-5444. EPA: how to find it.

PFAS (“forever chemicals”)

EPA UCMR 5: 8 entry points tested Apr 2023 to Jan 2024. "Average" is the highest entry-point average (non-detects counted as zero), the way EPA compares UCMR 5 results to the limits. ppt = parts per trillion. These results do not determine compliance.

Why "rounds to the limit"? the PFHxS average (12.3 ppt) and the Hazard Index (1.23) are slightly above the number on paper, but EPA compares results after rounding to the limit's precision (4.4 ppt rounds to 4), so they meet the limit as EPA applies it. Close enough to the limit to be worth watching.

For context: the PFOS average is higher than at 94% of the Nebraska systems EPA tested.

29 PFAS tested, 4 detected at least once. "Not detected" means below EPA's reporting limit (about 2 to 20 ppt depending on the chemical), not proven zero. PFAS not listed were not detected. The limits for PFHxS, PFNA, GenX and the Hazard Index were proposed for rescission in May 2026. That proposal is not final. Systems have until 2029 to meet the limits.

Lithium

Detected in 16 of 16 samples. Highest result 30.9 ppb. EPA's non-enforceable screening level is 10 ppb. Above screening level The screening level is how EPA decides what to study further, not a health limit. There is no federal limit for lithium and no filter is certified to remove it. About lithium.

Lead and copper

Copper 90th percentile: 3.67 ppm (Dec 2001), action level 1,300 ppb.

Lead comes from pipes and fixtures, not the source water, so it varies home to home. The 90th percentile means 9 in 10 sampled homes were at or below it. More on lead.

Health-based violations mean a contaminant exceeded a limit or a required treatment step was missed. Monitoring and reporting violations mean required tests or reports were late or missing, so the water's quality during that time is unknown. The total includes every violation in EPA's records, most of them paperwork.

For the official word, read the utility's annual Consumer Confidence Report.

Yes. EPA's 2023–2025 testing of City of Grand Island found 4 PFAS at least once. The highest entry-point averages were above the federal limit for PFOS: PFOS 7.3 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).

What is the lead level in Grand Island water?

The most recent 90th-percentile lead result for City of Grand Island is 1.98 ppb, for the period ending Dec 2025. The federal action level is 15 ppb, falling to 10 ppb in November 2027. The 90th percentile means 9 in 10 homes sampled were at or below this number. Individual homes can be higher.
