Housing Age Profile
If you live in one of the pre-1986 homes in Rolla, a certified lab test for lead is the direct way to learn what your tap delivers; the median build year of 1945 is only context.
Over half of homes in Rolla were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Rolla: 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.
