Housing Age Profile

When a home in Union was built matters for lead because federal rules adopted in 1986 limited how much lead new plumbing could contain; the local median build year is 1997. A median sits in the middle of a range, so some homes are older and some newer, and past repairs may have changed the pipes in either group. A plumber can identify the materials inside a home, and a lab test measures what reaches the tap.

Pre-1970 (Lead Pipes Risk)
Pre-1970 (24%) 1970–1986 (16%) Post-1986 (60%)

Most homes in Union were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

mg/L average of reported water-system 90th-percentile lead results (the 0.015 action level applies to each system's result, not to this average)

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.

Union: NFIP Claim Records and Water-Quality Context

103
Total FEMA Flood Claims
$43,808
Avg Reported Sum With Payment Data
100%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Union contains 103 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $43,808. 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 $300 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.
