Mashantucket Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
A median build year of 1996 in Mashantucket is characteristic of a mixed-era city where plumbing risk depends heavily on the specific property. Homes built before 1986 may have lead-soldered copper joints; those from before 1970 face the added possibility of lead service lines. The percentages above capture how much of the residential stock falls into each risk era.
Most homes in Mashantucket were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Mashantucket: 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.
Older interior plumbing shapes the local picture: 33% of Mashantucket homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.
