Housing Age Profile

For residents trying to assess tap water risk in Holy Cross, the median build year of 1961 is the starting context. It signals that a majority of homes were constructed before 1986 - the year federal rules prohibited lead solder in new plumbing - and that a significant share likely predates 1970, when lead pipes were still a common choice for residential service connections. Neither risk tier is rare in this housing inventory.

Holy Cross: Remediation Cost in Perspective

Median Home Value
$281,600
Est. Remediation
$3,000
Remediation as % of home value 1.1%

Remediation costs are moderate relative to home values in Holy Cross. The estimated $2,000–$4,000 range is manageable for most homeowners but still worth budgeting for. Home values are 71% above the Iowa average.

Protecting Children from Lead in Holy Cross

Homes Built Before 1986
0.0039
mg/L Avg Lead (Limit: 0.015)

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.

Before the federal solder ban, lead solder was a routine plumbing material, and 67% of the Holy Cross inventory was built in that earlier era - a share large enough to move household-level reads onto the standard list.
