How Old Is Roundhill's Housing Stock?
With 45% 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.

Housing Age Profile
Over the decades, Roundhill accumulated housing from multiple construction periods. The median build year of 1998 can be read against 1986, when lead solder in plumbing became federally prohibited - a regulatory line, not a safety line, and individual homes on either side of it can have different plumbing.
A significant portion of Roundhill's housing stock predates 1970, so some homes may have older plumbing materials. Residents in older homes should consider water testing.

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.
