Key Contaminants Detected in Stewartstown
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Stewartstown's Housing Stock?
With 42% 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
When a home in Stewartstown was built matters for lead because federal rules adopted in 1986 limited how much lead new plumbing could contain; the local median build year is 1998. A median sits in the middle of a range, so some homes are older and some newer, and past repairs may have changed the pipes in either group. A plumber can identify the materials inside a home, and a lab test measures what reaches the tap.
Most homes in Stewartstown were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Stewartstown: Remediation Cost in Perspective
The remediation-to-value ratio for Stewartstown sits at the bottom of the scale.
Estimated remediation costs in Stewartstown can be compared with local home values. The $450–$1,400 estimated range can be set against the median property value; actual costs vary by home. Home values are 44% above the Pennsylvania average.
Protecting Children from Lead in Stewartstown
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 Flood-Claim Evidence for Stewartstown
Historical NFIP data for Stewartstown contains 5 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $9,013. Among ZIP codes with claim records, 0% 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 $800 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 Stewartstown
- 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 Nitrite, listed in the water-quality records for Stewartstown: 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 42% 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.
