Housing & Infrastructure in Edison
With 77% 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
Heavily weighted toward older construction, Edison's housing stock carries a median build year of 1965. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Edison were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Edison Homeowners
Across the Edison housing market, the estimated remediation share sits at an elevated level — the cost-to-value ratio here is high enough that addressing documented water and safety issues becomes a material equity decision rather than routine maintenance, and most homeowners benefit from treating it as a structured financial planning exercise.
At 2.3% of home value, remediation costs in Edison represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $2,000–$4,100. Home values here are 27% below the Ohio average.
Lead Exposure Risk for Children in Edison
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.
When older housing represents 77% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Edison address.

Flood & Climate Risk in Edison
Within the NFIP's national dataset, Edison falls in moderate-exposure territory — 1 documented incident spanning multiple decades, with 100% of local ZIP codes sitting inside FEMA flood boundaries. That combination warrants inclusion in any thorough local water quality review.
Edison has a moderate flood history with 1 FEMA claims averaging $1,977 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.
