Housing Age Profile

When a city's housing median build year is 1965, as in Harmony, 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 Harmony were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Harmony

While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Harmony is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.

Median Home Value
$134,700
Est. Remediation
$400
Remediation as % of home value 0.3%

Remediation costs in Harmony are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 25% below the Indiana average.

Harmony: Lead Risk & Vulnerable Populations

71%
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 71% 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 Harmony address.
