Housing Age Profile
Because the majority of Mcconnelsville's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1975 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Mcconnelsville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

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 63% pre-rule share in Mcconnelsville keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
