Housing Age Profile

When a city's housing median build year is 1951, as in Castana, 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.

Over half of homes in Castana were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Castana: Remediation Cost in Perspective

Property equity in Castana sits at a moderate ratio to estimated remediation costs - a classification that reframes the household financial perspective from routine maintenance to deliberate budgeting, where most homeowners have a realistic path to addressing documented water and safety issues if they map the financial commitment against available resources before committing to scope.

Median Home Value
$107,900
Est. Remediation
$1,200
Remediation as % of home value 1.1%

Remediation costs are moderate relative to home values in Castana. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 34% below the Iowa average.

Protecting Children from Lead in Castana

69%
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.

When older housing represents 69% of the local inventory or aggregate readings approach the federal action level, an in-home check becomes the standard way to translate citywide averages into the specific reality of an individual Castana address.
