About
The Coal Authority awarded a contract to Soil Engineering Geoservices Limited for the drilling of mine water monitoring boreholes at the Thornley and Deaf Hill sites.
The purpose was to assess rising mine water and its potential impact on the surrounding environment, following a 2020 review that highlighted the risk of elevated mine water levels to overlying drinking water aquifers.
The contract involved constructing a borehole to intersect flooded underground workings and enable monitoring of mine water levels representative of the area.
The contract value was £661,980.4.
