## Description

The Coal Authority invites you to tender for the drilling of a mine water monitoring borehole\(s\) to assess rising mine water on the surrounding environment at sites at Thornley and Deaf Hill\. A review of the mine water block by the Coal Authority in 2020 highlighted the potential for elevated mine water levels at Thornely & Deaf Hill sites\. Elevated mine water levels could pose a risk to the drinking water aquifers that overlie the mine workings\. Therefore, the Coal Authority intend to construct a borehole to intersect flooded underground workings\. The borehole is to allow monitoring of mine water levels that are thought to be representative of the area\.
