Likely Pipe Material

With 58% 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.

Housing Age Profile

Decades of residential development in Union took place before the two main regulatory milestones that reduced plumbing-era lead risk: the phase-out of lead pipes before 1970, and the federal ban on lead solder in 1986. With a median build year of 1989, the housing stock here is anchored in that earlier period. The distinction between pre-1970 and 1970-to-1986 construction matters: the oldest homes may have lead pipes in the service line and lead solder in the copper joints, while the 1970-to-1986 tier still carries the solder risk even after lead pipes became less common. Together, these two risk layers affect a majority of the residential properties in the city - a fact the aggregate water quality data doesn't directly reveal.

Over half of homes in Union were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Union

When estimated remediation is placed alongside median property values in Union, the resulting ratio is low - a finding consistent with a household financial perspective where documented issues can be addressed without a meaningful impact on overall equity position, making this market one of the more favorable contexts for remediation planning.

Median Home Value
$290,300
Est. Remediation
$1,600
Remediation as % of home value 0.5%

Remediation costs in Union are relatively low compared to home values. The $800–$2,600 estimated range is a small fraction of median property value. Home values are 58% above the Illinois average.

Union: Lead Risk & Vulnerable Populations

Homes Built Before 1986
0.0018
mg/L Avg Lead (Limit: 0.015)

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.

Households with kids in the home - for whom CDC guidance places particular weight on minimizing exposure - face a specific local picture in Union. 58% of homes here come from the pre-rule era, and aggregate utility samples either approach or cross 0.015 mg/L. A baseline draw-test kit and certified lead-removal filtration are available via retailer networks for households confirming conditions at a specific tap.

Union: NFIP Claim Records and Water-Quality Context

23
Total FEMA Flood Claims

Avg Reported Sum With Payment Data
100%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Union contains 23 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $9,592. 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>$1,600</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.
