Housing Age Profile
Lead solder was allowed in new plumbing until the 1986 federal restrictions, which is why older homes in Roseville deserve a closer look; the median build year is 1990.
Most homes in Roseville were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Lead Exposure Risk for Children in Roseville
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.
