Title
Resolution to Approve a Construction Contract with Cascade Drilling, Limited Partnership for Sentinel Monitoring Well Installation (RFP 22-36) ($332,695.00)
Memorandum
This memorandum and resolution requests approval of a construction contract with Cascade Drilling for the Sentinel Monitoring Well Installation ($332,695.00).
A 1,4-dioxane plume is present in the groundwater in the City of Ann Arbor. The scope of this project is to install two sentinel monitoring wells between the 1,4-dioxane plume and the City’s drinking water supply at Barton Pond, to allow time to respond in the event 1,4-dioxane is detected. One well will be installed near the Miller/Maple Road intersection identified during previous modeling work. The second well will be evaluated to determine the best location given the recent detections identified in Scio Township. The wells will be targeted for City owned property or within City right-of-way. This project is programmed in the City’s Capital Improvements Plan UT-WS-22-19.
