Housing Age Profile
A median build year of 1993 in Eastport is characteristic of a mixed-era city where plumbing risk depends heavily on the specific property.

Lead Exposure Risk for Children in Eastport
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: 31% of Eastport 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.
