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 limitPFOA, PFOS above the federal limit in EPA's 2023–2025 testing (PFOA 21.1 ppt vs a limit of 4 ppt, PFOS 4.55 ppt vs a limit of 4 ppt, where ppt = parts per trillion).
Lead
Below action level3 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 2024. Your home's pipes can make yours higher.
Violations
Resolved2 health-based violations since 2016, most recently Oct 2021. 2 required an urgent public notice within 24 hours (the kind behind boil-water notices), most recently Oct 2021. What to do if you get a notice.
What you can do

PFAS (“forever chemicals”)

EPA UCMR 5: 5 entry points tested Nov 2024 to Oct 2025. "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.

For context: the PFOA average is higher than at 99% of the Minnesota systems EPA tested and the PFOS average is higher than at 95% of the Minnesota systems EPA tested.

29 PFAS tested, 7 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

Not detected in 10 samples (reporting limit 9 ppb). About lithium.

Lead and copper

Latest 90th percentile: 3 ppb lead (Jan 2022 – Dec 2024). Below action level

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.

Questions

Is Hastings Water System water safe to drink?

Hastings Water System had 2 health-based violations since 2016, all since resolved. EPA testing found PFAS above the 2024 federal limits, which systems must meet by 2029. Federal data can't tell you about your own pipes: lead comes from service lines and plumbing, so test your tap if your home was built before 1986. For the official word, read the utility's annual Consumer Confidence Report.

Does Hastings Water System water have PFAS?

Yes. EPA's 2023–2025 testing of Hastings Water System found 7 PFAS at least once. The highest entry-point averages were above the federal limit for PFOA and PFOS: PFOA 21.1 ppt, PFOS 4.55 ppt (limit 4 ppt for PFOA and PFOS, 10 ppt for the others).

What is the lead level in Hastings Water System water?

The most recent 90th-percentile lead result for Hastings Water System is 3 ppb, for the period ending Dec 2024. 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.
