HYDROGEOLOGY



GROUNDWATER INVESTIGATION


GEMS giving services in ground water work such as locating points where the availability of ground water in relation to depth, Quality & quantity etc., with help of suitable scientific instruments.The electrical resistivity method is best employed to estimate the thickness of overburden soil layer and also the thickness of weathered/fractured zones with reasonable accuracy and their relative water yielding capacities. Our expert staff of approved Geologists,Hydrogeologistsconducts ground water, surface water, water quality and water resource investigations to support all phases.GEMS has explored for and developed thousands of groundwater supplies for:

  • Municipal (towns, villages and hamlets)
  • Industries
  • Agricultural
  • Mining areas
  • Factories

GROUNDWATER CONTROL AND DEWATERING


In recent years the development of extractive industry, planning constraints on lateral extensions for quarries / Mines have put increased pressure for deepening of existing sites below the water table. In these industries, the energy costs of dewatering have become significant operational factors, whilst environmental constraints are often critical to the feasibility of these schemes.We have senior staff with very extensive experience of handling all aspects of this type of project.We assessed and managed difficult groundwater conditions to shape a design solution that would withstand ongoing water loads and minimise risk and disruption during activities. Our approach in all of these projects is to work closely with our clients to determine the most appropriate level of assessment required for each site. This ensures that we can achieve a cost effective solution in all cases.



AQUIFER STORAGE AND RECOVERY


GEMS has provides Aquifer Storage and Recovery as an alternative to surface reservoirs and as a creative solution to more efficient management of water resources. It includes water storage and recovery in both alluvial and confined aquifers. However, the terms “Contained Subsurface Reservoirs” and “Porosity Storage Reservoirs” are specifically used for storage in alluvial aquifers. Wells are used to inject the water into the aquifer and pump the water out of the aquifer. The loss of water in surface reservoirs to evaporation and seepage, which is not recoverable, is no longer being viewed as “the price of business,” but as a major setback. Getting more water for less money, and with less impact to the environment, is a reasonable course of action. Here is a short list of potential benefits of aquifer storage reservoirs:

  • Increased water yields by eliminating evaporative losses
  • Improved water quality& reduced impacts from drought
