How Old Is Harmans's Housing Stock?
With 46% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Plumbing materials follow installation dates, not medians. Harmans records a median build year of 2018, and a meaningful share of its homes date from before the 1986 federal lead restrictions.
A significant portion of Harmans's housing stock predates 1970, so some homes may have older plumbing materials. Residents in older homes should consider water testing.

Protecting Children from Lead in Harmans
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
