What's in Del Valle's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Del Valle Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
A post-1986 majority in Del Valle's housing inventory — median build year 2007 — generally signals lower aggregate plumbing-era lead risk.
Most homes in Del Valle were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

How Remediation Costs Compare in Del Valle
Property value and cost data for Del Valle produce a moderate remediation-share classification — a level where advance financial planning has real practical value and the commitment is realistic for most homeowners who approach it deliberately.
Remediation costs are moderate relative to home values in Del Valle. The estimated $1,750–$3,900 range is manageable for most homeowners but still worth budgeting for. Home values are 9% above the Texas average.
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: Flood History & Water Damage Risk
The National Flood Insurance Program captures decades of claims at the local level, building a record of cumulative community flood exposure. For Del Valle, that record documents 71 claims and 100% of ZIP codes inside FEMA-designated flood zones. What makes those numbers relevant to water quality is the set of mechanisms flooding activates: heavy precipitation that floods treatment intake zones can introduce contaminants upstream of normal filtration; well casings in low-lying areas can be infiltrated by floodwaters carrying bacteria, sediment, and chemical residue; and distribution system pressure changes during flooding can create backflow conditions. These effects become more probable as flood frequency and magnitude increase — and the NFIP record indicates both are meaningful factors locally.
Del Valle has a moderate flood history with 71 FEMA claims averaging $24,767 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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. Flood damage can add significantly to the estimated <strong>$2,700</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
