Trane Technologies — Well Abandonment Program

Project Overview

IET performed a well abandonment program at 400 Friendship Road in Sylvania, Georgia for Arcadis US Inc on behalf of Trane Technologies (formerly Ingersoll Rand). The work was completed April 13–15, 2026 under Work Order IET-040626-Sylvania (Arcadis Project No. 30319919.00004).

The program involved proper abandonment of both 2-inch and 4-inch monitoring wells in accordance with Georgia environmental regulations, including grouting, removal of surface completions, and surface restoration. IET mobilized skid steer equipment for surface patching operations.

All investigation-derived waste (IDW) was drummed and managed on-site. The project was completed on schedule in 3 field days.

Technical Approach & Well Abandonment Methodology

Monitoring well abandonment is a regulated procedure that permanently decommissions wells no longer needed for environmental monitoring — eliminating them as potential conduits for groundwater contamination, safety hazards, or regulatory liabilities. Proper abandonment requires removing any surface completions (protective casings, concrete pads, traffic-rated vaults), over-drilling or reaming the existing well casing to expose the full borehole annulus, removing the casing and screen, and filling the entire borehole from bottom to surface with an approved grouting material.

For the Trane Technologies site in Sylvania, Georgia, IET performed abandonment of both 2-inch and 4-inch diameter monitoring wells. The different well diameters reflect different construction standards and monitoring purposes — 2-inch wells are standard for shallow groundwater monitoring, while 4-inch wells are typically used for deeper installations or where pumping tests require larger pump access. The abandonment of both well types on the same site required appropriate drilling equipment for each diameter, with over-drilling or reaming as needed to ensure complete grout placement around the full borehole circumference.

The 12 surface completions removed and patched on this project indicate a multi-well monitoring network being decommissioned — likely as part of a regulatory site closure or transition to post-closure monitoring. Each surface completion (concrete pad, protective steel casing, or traffic-rated vault) was removed, the well was properly grouted, and the surface was patched to match surrounding grade. This complete surface restoration is essential for sites being returned to active use or property redevelopment, where abandoned well completions could create tripping hazards or interfere with surface operations.

Site Context & Regulatory Framework

Sylvania, Georgia is located in Screven County within the Coastal Plain physiographic province of southeastern Georgia. The shallow geology consists of Quaternary and Tertiary-age unconsolidated sediments — predominantly sand, clay, and limestone units of the Floridan Aquifer System. The Floridan Aquifer is one of the most productive groundwater systems in the world and is a critical drinking water source for southeastern Georgia, making proper well abandonment essential to prevent aquifer cross-contamination.

Well abandonment in Georgia is regulated by the Georgia Environmental Protection Division (GA EPD) under the Water Well Standards Act and related rules. Monitoring well abandonment at industrial sites like the Trane Technologies (Ingersoll Rand) facility requires coordination with the environmental consultant (Arcadis US) and compliance with site-specific closure plans approved by GA EPD. The project was managed by Arcadis PM Andrew Davis with IET's PIC/Area Manager David Gomes, and IET Sales Rep Randy Phillips — reflecting the multi-party coordination typical of corporate facility environmental closure projects where the property owner, environmental consultant, and drilling contractor each have specific regulatory and contractual responsibilities.
