HydroGeophysical and Environmental Science Consultants (HESC) is operating since 1996 and has provided services in the fields of hydrogeology, drilling of water wells, geotechnical investigations, soil environmental engineering, IEE/EIA, water supply and sanitation, soil and subsurface investigation, geophysical investigation, vegetation ecology, and wild life. The powerful tools of HESC field of speciality include the Drilling of water wells, Numerical Groundwater Flow and Contaminant Transport Modeling and Hydrogeophysical studies, Air Plume Modeling Simulation related to Industrial Pollution through smoking vents / Accidental Fire Hazard. Processing ModFlow (PMWIN5), a state of the art tool in the modeling industry is used to simulate and predict different scenarios of development plume due to leakage from petroleum storage tank, evaporation pond, landfill sites, shallow and deep injection wells. A new design, management and remedial action plan is then chalked out in the light of existing ambiguities. FLUENT (Version IV, resided in Sun Workstation), a worldwide used tool to develop a 3-dimension Air Plume Modeling of the gases emission of industrial vents.
