Shadowed environmental consultants today. A cable percussive rig was used to drill boreholes on an old quarry site. Environmental samples from the ground were taken at each strata to test for possible contamination and to assess the strength of the rock. The different strata were logged and samples were taken to test for volatile organic compounds, inorganic substances and contaminates in leachate. Further samples were also taken to test for moisture content, particle size distribution and plasticity. A previous well was also checked for levels of methane, carbon dioxide and oxygen.
On the hottest day recorded in July, we also experienced a little storm and lightning! Lightning and standing next to next to rig, not a great combination. I now have a greater appreciation of how hard it may be to dig these boreholes and different types of strata you may come across. Never knew you could have that many types of mudstone. Did you know that, you needed to be qualified to drill and be part of the British Drilling Association?
