Study of soil and groundwater contamination

By means of borehole drilling, sampling and analysis

Drilling of boreholes and soil/water sampling and analysis is typically performed in order to:
 

  • Identify (or specify) geological and hydrogeological conditions on site (soil and subsoil composition, water bearing and waterproof deposits, groundwater level and flow direction, interaction between groundwater and surface water, etc.)
  • Determine nature and distribution of soil and groundwater contamination


Evaluation of site environmental sensitivity regarding groundwater and nearby surface water bodies (stream, creek, lake, etc) should be taken into account while considering the need of water sampling or water quality monitoring.
Moreover, the number, location and distance between soil borings will depend on:

  • Location of possible groundwater contamination sources (identified during Phase I Site Assessment)
  • Potential soil and groundwater contamination level (based on results obtained during Phase I Site Assessment)
  • Potential impacts from adjacent areas (based on results obtained during Phase I Site Assessment)
  • Previous soil gas analysis and/or geophysical measurement results
  • Site size
  • Local relief
  • Supposed or known water flow direction
