Key Contaminants Detected in Walnut Grove
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Walnut Grove's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Walnut Grove's residential inventory spans multiple construction eras, with the median build year of 1997 landing in a zone where pre- and post-1986 homes are both well represented. That split matters because homes built before 1986 may contain lead-soldered copper joints — a plumbing practice banned that year — while those built before 1970 face the additional possibility of lead pipes in the service line. Whether a specific household sits on the older or newer end of this distribution is the primary variable shaping its individual exposure risk.
Most homes in Walnut Grove were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Climate-Related Water Risk for Walnut Grove
