Top Contaminants in Jamison Water
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Housing & Infrastructure in Jamison
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Construction dates in Jamison center on a median of 1997, and the Census figures behind it describe when homes were built, not what materials they contain.
Most homes in Jamison were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.
Source: U.S. Census Bureau ACS B25034.
Cost Context: What Remediation Means for Jamison Homeowners
The remediation-to-value ratio for Jamison sits at the bottom of the scale.
Estimated remediation costs in Jamison can be compared with local home values. The $400–$800 estimated range can be set against the median property value; actual costs vary by home. Home values are 184% above the Pennsylvania average.
Lead Exposure Risk for Children in Jamison
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.
While lead results averaged over Jamison ZIP codes come in under 10 micrograms per liter, that figure combines many 90th-percentile values and cannot describe one building, including the 29% of housing that predates 1986.
Sources: EPA Lead and Copper Rule, U.S. Census Bureau ACS, CDC childhood lead poisoning prevention guidelines.
Historical NFIP Claim Context in Jamison
Historical NFIP data for Jamison contains 7 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $21,662. 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 $600 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 Jamison
- 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 Haloacetic Acids (HAA5), listed in the water-quality records for Jamison: 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. Homes built before 1986 may have lead solder in pipes. A licensed plumber can assess your risk.
- 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.
