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

Del Valle: Lead Risk & Vulnerable Populations
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.
Reading Del Valle's aggregate samples next to its housing-age figures yields a quiet baseline. Lead rests under the federal action benchmark in citywide monitoring, and only 23% of homes were built before the federal ban on solder containing lead. Households with kids - the population for whom CDC guidance places particular weight on minimizing exposure - can confirm in-home conditions with a draw-test kit, with a certified lead-removal filter available through certified retail channels if results warrant it.

Del Valle: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Del Valle contains 71 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $33,675. 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>$2,700</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.
