Housing Age Profile

When a city's housing median build year is 1986, as in Thompsonville, the implication for water quality research is straightforward: municipal-level data captures what leaves the treatment plant, but household plumbing from before 1986 determines what actually arrives at the tap. In cities where older housing predominates, that gap between system-level and household-level data is widest.

Pre-1970 (Lead Pipes Risk)
Pre-1970 (26%) 1970–1986 (28%) Post-1986 (46%)

Over half of homes in Thompsonville 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 Thompsonville Homeowners

The household financial picture for Thompsonville homeowners is proportionally favorable - addressing documented issues claims a small slice of equity, and the cost-to-value ratio puts this area well within the manageable tier.

Median Home Value
$99,500
Est. Remediation
$900
Remediation as % of home value 0.9%

Remediation costs in Thompsonville are relatively low compared to home values. The $300–$1,600 estimated range is a small fraction of median property value. Home values are 46% below the Illinois average.

Lead Exposure Risk for Children in Thompsonville

54%
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.

Even where utility-side monitoring meets Lead and Copper Rule requirements, the 54% pre-rule share in Thompsonville keeps interior-plumbing variation as a household-level question that aggregate data cannot resolve.
