Housing Age Profile
Over the decades, Carville accumulated housing from multiple construction periods. The median build year of 1996 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 Carville's housing stock predates 1970, so some homes may have older plumbing materials. Residents in older homes should consider water testing.

Carville: Lead Risk & Vulnerable Populations
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.
