With 92% 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

While newer cities carry lower aggregate plumbing risk from lead-era construction, Thompson sits firmly in the older category. The median build year of 1957 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 Thompson 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 Thompson Homeowners

Across the Thompson housing market, the estimated remediation share lands in a middle tier - not a minor footnote, but not a prohibitive burden either; the cost-to-value ratio reflects a moderate equity commitment, one that sits above routine maintenance territory and warrants a dedicated line in the household budget.

Median Home Value
$94,400
Est. Remediation
$1,200
Remediation as % of home value 1.3%

Remediation costs are moderate relative to home values in Thompson. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 43% below the Iowa average.

Lead Exposure Risk for Children in Thompson

92%
Homes Built Before 1986

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 92% of Thompson 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.
