What's in Williamson's Water?
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Williamson Infrastructure Age
With 73% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
What does a median build year of 1979 mean for water safety in Williamson? It means the majority of the city's residential plumbing was installed before 1986, when lead solder was federally banned, and a large share may predate 1970, when lead pipes were commonly used — making plumbing age a central variable in household-level lead risk across much of the city.
Over half of homes in Williamson were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Williamson
Remediation costs in Williamson represent a substantial share of typical property values — the equity impact here is significant, and careful financial planning is essential rather than optional for most homeowners.
At 2.7% of home value, remediation costs in Williamson represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,500–$4,000. Home values here are 33% below the West Virginia average.
Williamson: 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.
Practically, the structural drivers in Williamson — 73% pre-rule stock and citywide monitoring at or beyond the regulatory benchmark — make an in-home draw the practical way to translate aggregate averages into the specific conditions at one address.

Williamson: Flood History & Water Damage Risk
Across the multi-decade NFIP program, Williamson has logged 722 filed flood claims — a tally that corresponds with 100% of local ZIP codes carrying FEMA flood zone designations. For water quality, the implications extend beyond property damage: when flooding reaches the magnitude this area's record implies, water supply systems face compounding stress. Treatment plants handling contaminated floodwater intake face sharply elevated contaminant loads. Private wells in low-lying FEMA zones are vulnerable to surface infiltration during each major event. Distribution networks can experience pressure-inversion backflow, drawing untreated water back into the supply. These are not remote possibilities at this exposure level.
Williamson has a significant flood history with 722 FEMA flood insurance claims on record, averaging $21,638 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.
