Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Clarkston's Housing Stock?
With 49% 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 solder was allowed in new plumbing until the 1986 federal restrictions, which is why older homes in Clarkston deserve a closer look; the median build year is 1993.
Most homes in Clarkston 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.
Clarkston: Remediation Cost in Perspective
Estimated remediation for Clarkston is a small fraction of median property value - one percent or less - though the ratio does not describe any single household.
Estimated remediation costs in Clarkston can be compared with local home values. The $550–$1,400 estimated range can be set against the median property value; actual costs vary by home. Home values are 106% above the Michigan average.
Protecting Children from Lead in Clarkston
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 Clarkston
Historical NFIP data for Clarkston contains 8 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $3,223. 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 $900 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.
