Housing & Infrastructure in Enning
With 47% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile
Enning's residential inventory spans multiple construction eras, with the median build year of 1999 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.
A significant portion of Enning's housing stock predates 1970, when lead pipes were commonly used. Residents in older homes should consider water testing.

Lead Exposure Risk for Children in Enning
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.
Wherever 47% of local housing was built before solder rules changed — as is the case in Enning — a faucet-level sample closes the gap that aggregate utility data cannot.
