Likely Pipe Material

Housing Age Profile

Lead solder was standard in copper plumbing until federally banned in 1986; lead pipes were common in service lines pre-1970. Douglas's median build year of 1984 reflects a housing stock where these older materials are a pervasive feature - not a rare legacy - of the residential plumbing landscape.

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

Douglas: Lead Risk & Vulnerable Populations

50%
Homes Built Before 1986
0.0024
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.

After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted - but 50% of the Douglas inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

Douglas: NFIP Claim Records and Water-Quality Context

3
Total FEMA Flood Claims
$2,837
Avg Reported Sum With Payment Data
0%
A/V Share of Claim-Record ZIPs

Historical NFIP data for Douglas contains 3 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $2,837. 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>$2,400</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.
