Sonora Infrastructure Age
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.

Housing Age Profile
Homes on the same street in Sonora can differ: one may keep original pre-1986 plumbing while another has been replumbed, so the 2009 median is only a starting point.
A significant portion of Sonora's housing stock predates 1970, so some homes may have older plumbing materials. Residents in older homes should consider water testing.

Sonora: 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.
