How do I find out if my Green Oaks home has a lead water line?

The village posts its IEPA lead service line material inventory spreadsheet (address-by-address) on the Engineering page of greenoaks.org. Per the CCR, residents can obtain a copy of the service line inventory and lead tap sampling data by emailing Jason DesBiens at jdesbiens@gha-engineers.com. The village's IEPA public notice tells residents: "Learn what your service line material is. Contact us at leadtesting@greenoaks.org or a licensed plumber," and points to EPA's Protect Your Tap guide (www.epa.gov/pyt).

Does GS Construction replace lead service lines?

Service-line replacement itself is licensed plumbing and excavation work — on GS projects it runs through our Illinois-licensed plumbing and excavation partners, and we handle what comes after: restoring the yard, landscaping edges, and any interior finishes the work touched. If a remodel uncovers a lead line, we flag it and point you at the municipal program before anyone spends your money.

Lead water pipe replacement in Green Oaks

not published — no lead service line replacement program or cost-sharing policy appears anywhere on greenoaks.org or in the 2025 CCR. Notably, the village's posted IEPA Lead Service Line Inventory (479 service lines) records ZERO lead lines and zero galvanized-requiring-replacement lines: all utility-side lines are copper (476) or cast/ductile iron (3); 431 lines classified Non-Lead, ~47 with customer-side material still blank/unverified. With no lead lines identified, there is nothing published to replace.

Green Oaks's program at a glance

Who supplies the water

Village of Green Oaks operates its own small community water system (Public Water System ID IL0970040) as purchased surface water — the 2025 CCR states "Waukegan is the Source of Green Oaks Water" (Lake Michigan water bought wholesale from the City of Waukegan; single metered connection at O'Plaine Rd and Dan Patch Ln). The system is small (~479 service lines in the inventory) and much of the village is on private wells/septic — connection to village water is only required if a well fails. Day-to-day water operations are handled by the village's engineering firm, Gewalt Hamilton Associates (water operator Jason DesBiens, 847-821-6207).

Worth knowing

Compliance history is the main story: the 2025 CCR's violations table shows Green Oaks failed to develop and submit its initial service line inventory to Illinois EPA by the October 16, 2024 deadline (LSL INVENTORY-INITIAL and LSL REPORTING-INITIAL violations), failed the known/potential-LSL consumer notification certification (07/02/2025), and had a linked public-notice violation (08/22/2025–01/12/2026). The village mailed an IEPA public notice to customers on January 12, 2026 stating: "the Village of Green Oaks is preparing a lead service line inventory and plans to submit the inventory to the IEPA in Winter, 2026. Customers will be notified should they be impacted by an identified lead service line via mail." The CCR adds the inventory work has "less than 20 homes remaining." The now-posted inventory (filename dated 2026-04-20) shows 479 lines, 0 lead, 0 GRR — a fairly new system (homes mostly 1980s-2000s per install years), so lead lines are unlikely. Lead 90th percentile was 5 ug/L (Aug 2023 sampling), well under the 15 ug/L action level. Residents on private wells are outside this system entirely. Corrosion control: 60/40 poly/ortho phosphate blend treated at Waukegan's source.

The Illinois picture

Illinois' Lead Service Line Replacement and Notification Act requires every community water supply to inventory its service lines and replace lead ones on a state-mandated schedule. Two practical consequences for homeowners: your municipality can tell you what your line is made of, and full replacement — not partial — is the standard when work happens. Many suburbs coordinate replacements with water-main projects, which is often when the cost-sharing is most generous.

Where we come in

Remodels are where lead lines get discovered — kitchen and bath projects expose the plumbing, and permit inspections check service-line material against the municipal inventory. When that happens on a GS project in Green Oaks, we flag it early, point you at the program above before anyone spends your money, run the replacement through our Illinois-licensed plumbing and excavation partners, and restore everything the dig touched.

GS Construction & Remodeling is a licensed general contractor, not a municipal agency. Program details above summarize official municipal sources and change over time — confirm current terms with Green Oaks before making decisions based on them.

Why do lead lines come up during remodels?: Kitchen and bathroom remodels expose the plumbing where it enters the home, and permit inspections increasingly check service-line material against the municipal inventory Illinois law requires. Finding out mid-project is normal — knowing your village's program before demo day is better.
