With 74% 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

Two dates define the high-risk tiers of residential plumbing from a lead standpoint: 1970, before which lead pipes were commonly installed for service connections, and 1986, before which lead solder was standard in copper plumbing. A median build year of 1954 places Williamson's housing distribution well within that older risk zone. The bar chart above breaks down how much of the stock falls into each era — and the pre-1986 share alone represents more than half the residential inventory, making plumbing-era risk a defining characteristic of the local water safety picture.

Pre-1970 (Lead Pipes Risk)
Pre-1970 (53%) 1970–1986 (21%) Post-1986 (26%)

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

The household financial perspective in Williamson reflects a moderate cost-to-value ratio — an equity share that is not trivially small but remains within the range where most homeowners can address documented water and safety issues by treating the expense as a real line item in property planning rather than a discretionary one.

Median Home Value
$173,500
Est. Remediation
$2,200
Remediation as % of home value 1.3%

Remediation costs are moderate relative to home values in Williamson. The estimated $1,200–$3,300 range is manageable for most homeowners but still worth budgeting for. Home values are 52% below the New York average.

Williamson: Lead Risk & Vulnerable Populations

74%
Homes Built Before 1986
0.0012
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.

Locally, 74% of Williamson homes carry interior plumbing from the era when lead solder was still permitted in new builds, and citywide monitoring approaches or crosses the EPA action benchmark. Households can find a draw-test kit and certified filtration through verified retailers.

Williamson: Flood History & Water Damage Risk

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>$2,200</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.
