Project Update – Ledge Investigations

Ledge investigations within the potential wastewater system service area are tentatively scheduled for the week of June 19th. 

Why is this happening? 
This work is being conducted to determine the depth of bedrock in specific areas.
​
How do ledge investigations work? 
This work involves using a mini drill rig called a Geoprobe, which is mounted on a rubber tracked ATV unit. The Geoprobe will push a two-inch diameter probe into the ground until it reaches “refusal,” or the point where the probe hits a material that it cannot go through - bedrock.

​Where will this work happen?
The bedrock probes will be advanced within the right of way along roads where the collection system is proposed to run. 

Will any work be done on private property? 
If site specific information outside of the right of way is required, Stone Environmental Inc. will contact the individual property owners in advance to request permission to use the geoprobe on their properties. 

Is there any noise, traffic, or earth disturbance?
The bedrock probes create minimal earth disturbance but do create noise. For this reason, ledge probes are scheduled for later in June to avoid creating noise during school times, and to prevent creating delays around Westford School drop-off and pick-up times.
