Hydrogeological exploration

        Hydrogeological exploration implies the application of modern methods and equipment for exploration of underground aquifers in which groundwater of privileged directions is accumulated. It also implies the exploration of the speed and direction of groundwater movement, determining the optimal capacity of wells and springs.

• design, drilling and equipping of exploration boreholes and wells with diameter of 76 to 1050 m, for the purpose of water supplying, water bottling, spas, swimming pools, irrigation of mines, drainage, landslides rehabilitation, etc.
• Geophysical exploration of terrain (refractive seismic, shallow reflection seismic, geomagnetic and geo-electrical probing, LUND)
• Preparation of the studies on reserves and quality of mineral raw materials and ground waters, designs of detail geological and hydrogeological explorations, revisions, etc., until the final concession to the bearing or source is obtained
• design, drilling and equipping of new wells for the needs of cities, settlements, enterprises, spas, and water bottling factories, with diameter of 150 to 1050 mm with the depth up to 1500 m.
• Drilling of well by rotary drilling method with water and specific flushing methods, compressed air - stroke-pneumatic method, so called "DTH - down the hole system"
• Testing of boreholes and wells by pumping
• Monitoring of ground waters (regime monitoring)
• Mathematical modelling of underground flow, applying the newest software
• Computer procession of data of monitoring and wells testing
• Execution and rehabilitation of water disinfection systems (chlorination, ozonisation, UV-treatment)
• Preparation of the program for sanitary protection of sources, wells, and other objects
• Determination of direction and velocity of ground water flow, using "tracer" or Grapho-analytical method for analysing of test pumping data
• Forecast of migration of polluters in aquifers
• Application of remediation method for ground waters and Geo-environment
• Determination of optimal capacity of wells and selection of the pumping equipment
• Determination of resistance at filter construction of the well, due to obturation ("aging")
• Cleaning and regeneration of "older" wells, which capacity is reduced to only 30 % of the capacity that the well had when first constructed
• Recording of interior of the well by underwater camera
• Measuring of water inflow through different segments of the well’s filter
• Hydro-Chemical analysis (determination of over 30 Physical-Chemical parameters) of water samples in the field
• laboratory Physical-Chemical analysis of water
• laboratory analysis of tracer concentration in ground water
• laboratory analysis of permeability coefficient (filtration) at the samples of soil and rocks in permeameter
• design and execution of new and reconstruction of specific water supply objects, etc.
