How Old Is Williamstown's Housing Stock?
With 94% 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
Housing age is one of the most reliable proxies for plumbing-era lead risk, because two federal milestones - the widespread use of lead pipes before 1970 and the continued use of lead solder until 1986 - define the highest-risk tiers of the residential housing stock. With a median build year of 1901, Williamstown falls squarely within the older range - meaning a large fraction of the housing was built under the plumbing standards of those earlier eras. The distribution above captures where that risk concentrates, and why older neighborhoods warrant particular attention from residents concerned about tap water quality.
Over half of homes in Williamstown were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Williamstown: Remediation Cost in Perspective
Middle of the range - Williamstown homeowners face a remediation share that calls for real financial attention without reaching crisis territory.
Remediation costs are moderate relative to home values in Williamstown. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 47% below the Pennsylvania average.
Protecting Children from Lead in Williamstown
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Williamstown have approached or crossed the regulatory action level on multiple occasions. Combined with 94% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.
