Key Contaminants Detected in Coloma
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Coloma's Housing Stock?
With 73% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Coloma's median build year of 1961 reflects a housing stock where these older materials are a pervasive feature - not a rare legacy - of the residential plumbing landscape.
Over half of homes in Coloma were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Coloma: Remediation Cost in Perspective
At current valuations, Coloma sits in the low remediation-share tier - the equity impact of fixing documented issues is proportionally minor.
Remediation costs in Coloma are relatively low compared to home values. The $800–$1,800 estimated range is a small fraction of median property value. Home values are 4% below the Michigan average.
Protecting Children from Lead in Coloma
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 73% pre-rule share in Coloma keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.

Historical Flood-Claim Evidence for Coloma
Historical NFIP data for Coloma contains 41 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, 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 <strong>$1,200</strong> 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.
