Key Contaminants Detected in South Lebanon
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is South Lebanon's Housing Stock?
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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
With a median build year of 1990, South Lebanon's housing stock reflects a city built across multiple eras. A substantial share of homes predate 1986 — the year lead solder in plumbing was federally banned — meaning the risk from plumbing materials is unevenly distributed across the city's neighborhoods and property types.
Most homes in South Lebanon were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

South Lebanon: Remediation Cost in Perspective
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in South Lebanon is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in South Lebanon are relatively low compared to home values. The $2,000–$4,100 estimated range is a small fraction of median property value. Home values are 70% above the Ohio average.
Protecting Children from Lead in South Lebanon
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 47% of the South Lebanon 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.

Climate-Related Water Risk for South Lebanon
Over the multi-decade window covered by the National Flood Insurance Program, South Lebanon has accumulated 41 claims — a total that suggests more than isolated flood exposure. With 100% of ZIP codes in designated flood zones, the water-quality implications of flooding move from hypothetical to periodically relevant: treatment intake can be compromised, wells can be infiltrated, and distribution backflow can occur.
South Lebanon has a moderate flood history with 41 FEMA claims averaging $12,614 per payout. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. Flood damage can add significantly to the estimated <strong>$3,000</strong> remediation cost per household.
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.
