Housing Age Profile
When a city's housing median build year is 1984, as in Hewitt, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.
Over half of homes in Hewitt 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 Hewitt
In Hewitt, property wealth outpaces what documented remediation typically demands - the equity burden lands well within the low tier.

Hewitt: 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.
Even where utility-side monitoring meets Lead and Copper Rule requirements, the 51% pre-rule share in Hewitt keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
