Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile

Supply's residential inventory spans multiple construction eras, with the median build year of 1997 landing in a zone where pre- and post-1986 homes are both well represented. That split matters because homes built before 1986 may contain lead-soldered copper joints - a plumbing practice banned that year - while those built before 1970 face the additional possibility of lead pipes in the service line. Whether a specific household sits on the older or newer end of this distribution is the primary variable shaping its individual exposure risk.

Most homes in Supply were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Supply

Setting Supply remediation figures against its property market, the resulting ratio sits comfortably in the low tier - a classification that reflects the kind of household financial position where most homeowners can identify documented issues, schedule the work, and absorb the cost without it registering as a significant budget disruption.

Median Home Value
$229,800
Est. Remediation
$1,800
Remediation as % of home value 0.8%

Remediation costs in Supply are relatively low compared to home values. The $1,200–$2,600 estimated range is a small fraction of median property value. Home values are 3% below the North Carolina average.

Supply: Lead Risk & Vulnerable Populations

35%
Homes Built Before 1986

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.

Wherever 35% of local housing was built before solder rules changed - as is the case in Supply - a faucet-level sample closes the gap that aggregate utility data cannot.

Supply: NFIP Claim Records and Water-Quality Context

Total FEMA Flood Claims

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

Historical NFIP data for Supply contains 2,408 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $10,961. 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>$1,800</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.
