In Hatfield, the mean across ZIP codes of what water systems reported as their 90th-percentile lead results sits above 0.015 mg/L, and 64% of homes were built before 1986. A test of the tap a child drinks from shows the level in that home.
1 ZIP code (100% of the city's ZIP records) is served by a water system whose 90th-percentile lead result exceeds the EPA action level of 0.015 mg/L.

Historical Flood-Claim Evidence for Hatfield

Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The $4,440 remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.

What You Can Do in Hatfield
- Test your water at home. City-level data shows averages - your tap may differ. Consider testing your home's tap water for lead, since household plumbing can affect its level.
- Install a certified water filter. For Groundwater Rule, listed in the water-quality records for Hatfield: if it is a rule or reporting requirement rather than a contaminant, ask your utility what the record involved; for bacteria, follow any boil-water notice from your utility; for a specific chemical contaminant, check whether a filter is certified to reduce it. Not every contaminant has a consumer filter certification.
- Check your home's plumbing. With 64% of homes built before 1986, lead solder is a real possibility.
- Review your water system's CCR. If you use a community water system, request its annual Consumer Confidence Report for system-level test results or find it online.
