Housing & Infrastructure in Cardington
With 49% 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
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1982 places Cardington in the middle zone between those thresholds — with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
Most homes in Cardington were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Cardington Homeowners
For most Cardington homeowners, estimated remediation represents a moderate equity share — manageable with planning.
Remediation costs are moderate relative to home values in Cardington. The estimated $2,000–$4,100 range is manageable for most homeowners but still worth budgeting for. Home values are 8% below the Ohio average.
Lead Exposure Risk for Children in Cardington
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.
Before the federal solder ban, lead solder was a routine plumbing material, and 49% of the Cardington inventory was built in that earlier era — a share large enough to move household-level reads onto the standard list.

Flood & Climate Risk in Cardington
Flood exposure in Cardington is meaningful by NFIP measures — 1 claim on record and 100% of ZIP codes carrying FEMA flood zone designations. That level of activity makes flood history a relevant factor when evaluating local water quality over time.
Cardington has a moderate flood history with 1 FEMA claims averaging $7,998 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.
