Top Contaminants in Gillette Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Gillette
With 45% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.

Housing Age Profile
For a household in Gillette, a certified lab test of tap water answers what the median build year of 1992 cannot.
Most homes in Gillette were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Gillette Homeowners
The remediation-to-value ratio for Gillette sits at the bottom of the scale.
Estimated remediation costs in Gillette can be compared with local home values. The $150–$600 estimated range can be set against the median property value; actual costs vary by home. Home values are 14% below the Wyoming average.
Lead Exposure Risk for Children in Gillette
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical NFIP Claim Context in Gillette
Historical NFIP data for Gillette contains 20 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $2,565. Among ZIP codes with claim records, 50% 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 $300 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 Gillette
- Test your water at home. City-level data shows averages - your tap may differ. Check the certification, price and turnaround time of any water test kit or lab service.
- Install a certified water filter. For Lead and Copper Rule Revisions, listed in the water-quality records for Gillette: 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 45% of homes built before 1986, lead solder is a real possibility.
