How Old Is Thurman's Housing Stock?
With 45% 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
For a city with a median build year of 1981, Thurman carries a housing profile that straddles the 1986 federal ban on lead solder in plumbing. Neither predominantly new nor predominantly old, the stock presents a moderate aggregate risk environment — with individual risk varying sharply depending on when and where a specific home was built.
Most homes in Thurman were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Thurman: Remediation Cost in Perspective
Property values and remediation costs in Thurman combine to produce a high equity share — the financial burden here is significant.
At 2.1% of home value, remediation costs in Thurman represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,600–$4,100. Home values here are 29% below the Ohio average.
Protecting Children from Lead in Thurman
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 45% of Thurman 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 Thurman
Flood history in Thurman spans 2 NFIP claims and 100% flood zone coverage — enough to place it in moderate-exposure territory where flood events are genuinely recurring rather than statistical outliers. That distinction matters for water quality assessment because the connection between flooding and water safety is not uniform across communities. In low-exposure areas, flooding rarely generates the conditions needed to compromise treatment or distribution infrastructure. In high-exposure areas, it can do so repeatedly. Moderate-exposure communities sit in between: flood events occur with enough frequency to make periodic infrastructure stress a reasonable concern, particularly for private well owners and residents in lower-elevation FEMA-designated zones.
Thurman has a moderate flood history with 2 FEMA claims averaging $34,590 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>$2,800</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.
