Adams Run Infrastructure Age
With 42% 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
Plumbing risk in residential housing tracks directly to construction era: pre-1986 homes may have lead-soldered copper joints; pre-1970 homes may have lead pipes outright. Adams Run's median build year of 1997 places the city in a moderate risk zone where neither era dominates the housing inventory. Understanding which side of the 1986 threshold a specific property falls on — and whether it predates 1970 — is the most actionable starting point for a homeowner trying to assess their own tap water exposure.
Most homes in Adams Run were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Adams Run: Lead Risk & Vulnerable Populations
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.
After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted — but 42% of the Adams Run inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.

Adams Run: Flood History & Water Damage Risk

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies.

Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
