Likely Pipe Material

With 57% 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.

Source: U.S. Census Bureau American Community Survey (ACS).

Housing Age Profile

Because the majority of Columbus's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1980 reflects a city where lead-era plumbing materials are common rather than exceptional.

Pre-1970 (21%) 1970–1986 (36%) Post-1986 (43%)

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

Columbus: Lead Risk & Vulnerable Populations

57%
Homes Built Before 1986
0.0035
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.

Routinely in Columbus, where 57% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.

Columbus: NFIP Claim Records and Water-Quality Context

402
Total FEMA Flood Claims
$37,667
Avg Reported Sum With Payment Data
100%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Columbus contains 402 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $37,667. 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>$3,467</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.
