Housing Age Profile
Heavily weighted toward older construction, Ewen's housing stock carries a median build year of 1960. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Ewen were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Protecting Children from Lead in Ewen
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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 73% pre-rule share in Ewen keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
