Key Contaminants Detected in Colmar
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Colmar's Housing Stock?
With 51% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Lead can reach tap water from service lines, solder and brass fittings inside a building, which is why housing age draws attention in Colmar, where the median build year is 1986.
Over half of homes in Colmar were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Colmar: Remediation Cost in Perspective
Low tier for Colmar: remediation estimated at up to 1% of what homes are worth.
Estimated remediation costs in Colmar 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 136% above the Pennsylvania average.
Protecting Children from Lead in Colmar
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 Colmar
Historical NFIP data for Colmar contains 46 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $91,865. 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 Colmar
- 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 Groundwater Rule, listed in the water-quality records for Colmar: 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 51% 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.
