JS Drilling

Environmental, Geotechnical and Geothermal Contractors
JS Drilling Ltd was established in Thomastown, County Kilkenny in 2004.  The proprietor Jim Stephenson has over 25 years drilling experience in the UK & Ireland.  We provide nationwide geotechnical and environmental drilling services to Local Authorities, national and multinational environmental consultants, industry, mining and engineering companies.
 
The company has earned a reputation for quality drilling services and is renowned for its expertise in the environmental sector where we have significant experience in the investigation of contaminated land and groundwater quality.  In addition we have specialised experience in geotechnical and geothermal services.
 

Environmental Drilling

One of our specialist areas of expertise is the environmental sector where we have significant experience in the investigation of contaminated land and groundwater quality using undisturbed soil sampling techniques and full containment methods of drilling, including:

 

  • Installation of groundwater and gas monitoring wells at petrol stations landfills, brown-field sites, industrial sites (chemical, pharmaceutical food, manufacturing)

  • Monitoring wells for nitrates assessment on farms and research sites

  • Installation of pumping wells on landfill

  • Inclinometers, piezometers and monitoring wells at tailings ponds for the mining industry

  • Contaminated land site surveys

  • Test holes for the injection of oxygen releasing compounds on highly contaminated sites

  • Grouting & decommissioning of old mine shafts and workings

Geothermal Installations

Geothermal energy is heat from the ground, generally once under the frost layer the ground remains at a consistent range of between 8 – 13° C  in temperature.

 

Geothermal energy is not only very efficient offering up to a 400% overall energy saving but it is also one of the most environmentally friendly heating systems as there are zero emissions.

 

Monitoring Wells

JS Remediation was established from the importance of groundwater to public and private water supplies.  We have developed specialised skills and equipment for the assessment and rehabilitation of groundwater wells.  We have the only camera of its type in the Ireland, with a maximum depth of 300m, the camera can tilt and rotate giving high quality footage to enable us to identify potential issues allowing promotion of most suitable options for well rehabilitation or maintenance.  We have significant experience in the development of soil & groundwater remediation strategies.   Our services include:

 

  • Monitoring and rehabilitation of contaminated water and ground

  • Environmental assessments

  • Borehole monitoring programmes

  • Borehole camera surveys

  • Water well rehabilitation including relining, jetting & chemical treatment

  • Monitoring well rehabilitation with jetting & vacuuming equipment

  • PID & interface probes

  • Soil and groundwater remediation systems

  • Pump tests, and analysis

  • Chemical oxidation

  • Pump and treat systems

  • Diver logger monitoring

  • Oil/water separator with variable treatment

  • the use of  bioremediation in-situ and ex-situ· options

  • Free product recovery systems

 

Decommissioning

 

All decommissioning operations are carried out in accordance with industry best practice as outlined in UK Environment Agency guidance “Good Practice for Decommissioning Redundant Boreholes and Wells” Oct 2012.  In each case the design of the well and the underlying geology are taken into consideration and the decommissioning of the well is adjusted accordingly.
