Housing & Infrastructure in Harrison
With 48% 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
With a median build year of 1982, Harrison'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 Harrison were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Harrison Homeowners
Property equity in Harrison sits at a moderate ratio to estimated remediation costs — a classification that reframes the household financial perspective from routine maintenance to deliberate budgeting, where most homeowners have a realistic path to addressing documented water and safety issues if they map the financial commitment against available resources before committing to scope.
Remediation costs are moderate relative to home values in Harrison. The estimated $2,000–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 28% above the Ohio average.
Lead Exposure Risk for Children in Harrison
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 48% 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 Harrison address.

Flood & Climate Risk in Harrison
The National Flood Insurance Program captures decades of claims at the local level, building a record of cumulative community flood exposure. For Harrison, that record documents 64 claims and 100% of ZIP codes inside FEMA-designated flood zones. What makes those numbers relevant to water quality is the set of mechanisms flooding activates: heavy precipitation that floods treatment intake zones can introduce contaminants upstream of normal filtration; well casings in low-lying areas can be infiltrated by floodwaters carrying bacteria, sediment, and chemical residue; and distribution system pressure changes during flooding can create backflow conditions. These effects become more probable as flood frequency and magnitude increase — and the NFIP record indicates both are meaningful factors locally.
Harrison has a moderate flood history with 64 FEMA claims averaging $8,465 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.
