Housing Age Profile
Heavily weighted toward older construction, Coleman's housing stock carries a median build year of 1973. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Coleman were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Lead Exposure Risk for Children in Coleman
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.
Routinely in Coleman, where 63% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
