Housing & Infrastructure in Clinton
With 72% 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
The character of Clinton's housing stock is one of deep historical layering — a median build year of 1966 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Clinton 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 Clinton Homeowners
Within the Clinton property market, documented remediation claims a moderate slice of typical equity — real but budgetable.
Remediation costs are moderate relative to home values in Clinton. The estimated $1,750–$3,900 range is manageable for most homeowners but still worth budgeting for. Home values are 1% below the Wisconsin average.
Lead Exposure Risk for Children in Clinton
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.
In recent monitoring under the Lead and Copper Rule, citywide samples for Clinton have approached or crossed the regulatory action level on multiple occasions. Combined with 72% of stock dating from the pre-rule era, the picture supports baseline single-tap reads as a standard household-level step.

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.
