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.
