Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Lead risk in Sun Prairie appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.
