Housing Age Profile
While newer cities carry lower aggregate plumbing risk from lead-era construction, Charter Oak sits firmly in the older category. The median build year of 1901 indicates that more than half the housing stock was built before 1986, when lead solder was still legally used in residential copper plumbing - and a substantial portion likely predates 1970, when lead pipes were still commonly installed for service lines. These two thresholds together define the elevated plumbing risk environment that older housing cities carry, independent of what the municipal water supply delivers to the meter.
Over half of homes in Charter Oak were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Charter Oak: 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.
Wherever 95% of local housing was built before solder rules changed - as is the case in Charter Oak - a faucet-level sample closes the gap that aggregate utility data cannot.
