About PFAS contamination in Hastings
## Summary Hastings's municipal water supply has earned a D grade, meaning residents are being served water with PFAS contamination that exceeds federal health limits. Two compounds surpass EPA thresholds: PFOA was detected at 11.8 parts per trillion — nearly three times the federal limit of 4 parts per trillion — and PFOS came in at 4.55 parts per trillion, just above its 4 parts per trillion limit. The contamination has been traced to 3M manufacturing facilities in the region.
## What the data shows Testing identified multiple PFAS compounds in Hastings's water. Of the compounds with established federal limits, both PFOA (11.8 ppt) and PFOS (4.55 ppt) exceed the EPA's 4 ppt maximum. PFHxS was detected at 3.25 ppt, below its 10 ppt federal limit. Notably, PFBA was measured at 155.94 ppt — a strikingly high concentration — though the EPA has not yet set a federal limit for that compound. Several other compounds were detected but concentrations were not reported in available data.
## What residents should know Given the D grade and confirmed exceedances, residents may want to consider additional filtration at home; certified NSF/ANSI 58 reverse osmosis filters and NSF/ANSI 53 activated carbon filters are both recognized for reducing PFAS levels in drinking water. Hastings residents should also be aware that settlement funds from 3M related to Washington County contamination may be available to help address remediation costs — contact your water utility or local officials for details on eligibility. For the most current testing results and any remediation updates, contact the Hastings public water utility directly.
About this summary: Narrative text on this page was drafted by an AI model (claude-sonnet-4-6) from EPA UCMR 5 data and reviewed before publication. The numeric data above is reported by water utilities directly to the EPA. If you spot an error, email data@checkyourwater.org.
What Hastings residents can do
Hastings's water exceeds federal PFAS limits. We recommend residents take action:
- Install a reverse osmosis (RO) or activated-carbon water filter certified to NSF/ANSI Standard 53 or 58 for PFAS reduction. RO systems remove the widest range of PFAS compounds.
- Do NOT boil your water to remove PFAS — boiling concentrates them.
- Request your most recent Consumer Confidence Report from your utility and ask when PFAS treatment will be installed.
- Contact your local elected officials and water utility board to demand a remediation timeline.
- Get independent water testing through services like Tap Score (mytapscore.com) if you want to verify your in-home levels.
- Talk to your healthcare provider about PFAS exposure — especially if you are pregnant, nursing, or have young children.
