Housing Age Profile

When a city's housing median build year is 1955, as in Diagonal, 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 Diagonal 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 Diagonal Homeowners

How does remediation fit within the broader financial picture for Diagonal homeowners? The equity share is moderate - large enough that treating it as a real planning consideration makes sense, and manageable enough that most homeowners have a clear path to addressing documented water and safety issues when they approach the commitment with deliberate advance budgeting rather than as an unplanned expense.

Median Home Value
$104,300
Est. Remediation
$1,200
Remediation as % of home value 1.1%

Remediation costs are moderate relative to home values in Diagonal. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 37% below the Iowa average.

Lead Exposure Risk for Children in Diagonal

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.

After the federal action removing lead-bearing solder from new plumbing took effect, building practice shifted - but 69% of the Diagonal inventory predates that line. With aggregate samples near or beyond 0.015 mg/L, an in-home check moves out of the optional column into the standard list.
