How Old Is Carlton's Housing Stock?
With 48% 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
When trying to understand water quality at the household level, the year a home was built often matters more than any city-wide water report. That's because the 1986 federal ban on lead solder in plumbing, and the earlier phase-out of lead pipes before 1970, created sharp discontinuities in residential plumbing risk by construction era. Carlton's median build year of 1983 puts the city in the transition zone: a substantial share of the housing stock postdates the solder ban, but a comparable fraction predates it - with the oldest homes carrying both the solder risk and the pipe risk simultaneously. Whether any individual household sits on the safer or riskier side of these thresholds is the key question, and it's one the city-wide median alone can't answer.
Most homes in Carlton were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Carlton: Remediation Cost in Perspective
Equity impact data for Carlton lands in the favorable tier - remediation claims a small slice of what properties here are worth.
Remediation costs in Carlton are relatively low compared to home values. The $2,000–$4,000 estimated range is a small fraction of median property value. Home values are 9% above the Washington average.
Protecting Children from Lead in Carlton
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.
Older interior plumbing shapes the local picture: 48% of Carlton homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.

Historical Flood-Claim Evidence for Carlton
Historical NFIP data for Carlton contains 1 flood insurance claim. Among ZIP codes with claim records, 0% 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>$3,000</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.
