Key Contaminants Detected in Mansfield
Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
How Old Is Mansfield's Housing Stock?
With 81% 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
While newer cities carry lower aggregate plumbing risk from lead-era construction, Mansfield sits firmly in the older category. The median build year of 1953 indicates that more than half the housing stock was built before 1986, when lead solder was still legally used in residential copper plumbing — and a substantial portion likely predates 1970, when lead pipes were still commonly installed for service lines. These two thresholds together define the elevated plumbing risk environment that older housing cities carry, independent of what the municipal water supply delivers to the meter.
Over half of homes in Mansfield were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Mansfield: Remediation Cost in Perspective
Property values and remediation costs in Mansfield combine to produce a high equity share — the financial burden here is significant.
At 2.5% of home value, remediation costs in Mansfield represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $2,100–$5,213. Home values here are 29% below the Ohio average.
Protecting Children from Lead in Mansfield
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.
Although utility-side compliance with federal Lead and Copper requirements remains the system reference, that compliance does not extend down into interior plumbing. With 81% of Mansfield stock built before the solder ban and aggregate readings at or beyond the action mark, a household-level sample becomes the practical way to close that information gap.

Climate-Related Water Risk for Mansfield
Mansfield's flood exposure sits in the moderate range: 81 NFIP claims on record and 75% of ZIP codes within FEMA-designated flood zones. Residents with private wells or older infrastructure have reasonable grounds to factor flood timing into their water quality awareness.
Mansfield has a moderate flood history with 81 FEMA claims averaging $33,562 per payout. 75% 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>$3,250</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.
