Housing Age Profile
Roughly balanced between older and newer construction, Groveland shows a median build year of 1998 — a mid-range figure that places meaningful amounts of the residential inventory on both sides of the 1986 federal plumbing-solder ban.
Most homes in Groveland were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Groveland: Remediation Cost in Perspective
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Groveland 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.
Remediation costs in Groveland are relatively low compared to home values. The $1,200–$2,300 estimated range is a small fraction of median property value. Home values are 21% above the Illinois average.
Protecting Children from Lead in Groveland
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.
47% — that captures the slice of Groveland housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.
