Key Contaminants Detected in Macomb
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Macomb's Housing Stock?
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
Housing age is a rough starting point, not an answer. Macomb has a median build year of 2000, but any single home may be older or newer than that figure, may have had plumbing replaced, or may still have original fixtures. Lead can also come from a service line or older brass fittings, so a water test or a check of the utility's service line inventory says more about one address than the citywide build year does.
Most homes in Macomb were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Protecting Children from Lead in Macomb
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.
Pre-1986 construction accounts for about 18% of Macomb homes; older plumbing in any of them can still add lead at the tap.

Historical Flood-Claim Evidence for Macomb
Historical NFIP data for Macomb contains 45 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $19,718. 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.
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.
