Housing Age Profile
For residents trying to assess tap water risk in Charlestown, the median build year of 1972 is the starting context. It signals that a majority of homes were constructed before 1986 - the year federal rules prohibited lead solder in new plumbing - and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.
Over half of homes in Charlestown 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 Charlestown
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.
Despite Lead and Copper Rule oversight at the utility tier, citywide samples in Charlestown have moved beyond 0.015 mg/L - and 70% of local stock predates the ban on solder containing lead. The high-pre-1986 share combined with above-action samples leaves an in-home test and certified filtration via retailer networks as the household-tier tools, available for families with kids or pregnant residents. Periodic retesting after plumbing work or extended stagnation captures changes the initial draw cannot.
<strong>1 ZIP code</strong> (100% of the city) exceeds the EPA lead action level of 0.015 mg/L.
