How Old Is Webster'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
Tap water lead levels are shaped by two factors: what the utility delivers, and what the household plumbing adds to it. Older homes contribute disproportionately to that second variable because lead solder was standard in copper plumbing before 1986, and lead pipes were common before 1970. In Webster, where the median build year is 1983, a substantial share of the housing stock falls into these older categories. The bar chart above breaks out the pre-1970, 1970-to-1986, and post-1986 segments — the key ages for understanding where plumbing-era risk concentrates across the city.
Most homes in Webster were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Webster: Remediation Cost in Perspective
For most Webster homeowners, estimated remediation represents a moderate equity share — manageable with planning.
Remediation costs are moderate relative to home values in Webster. The estimated $1,600–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 0% above the Texas average.
Protecting Children from Lead in Webster
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 48% of the Webster inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Climate-Related Water Risk for Webster
The NFIP record for Webster is not ambiguous: 902 claims filed and 100% of ZIP codes in FEMA-designated flood territory add up to a substantial flood exposure profile. For a water quality assessment, that profile matters because flooding doesn't just damage property — it can temporarily compromise the systems that deliver safe drinking water, from overwhelmed treatment plants to infiltrated private wells to backflow events in distribution infrastructure.
Webster has a significant flood history with 902 FEMA flood insurance claims on record, averaging $31,554 per claim. With 100% of ZIP codes in FEMA-designated flood zones, flood risk is a major concern for homeowners and water quality.
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>$2,400</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.
