Environmental pollution has become a world wide concern. One of the main sources of such pollution is sewage wastewater and sludge. Their utilization without proper treatment can pollute the ecosystem (plant, soil, surface and ground water). Sewage wastewater and sludge contains several pollutants such as: pathogens, toxic organic compounds, heavy metals, high level of BOD & COD, seed weed. The...

Analyses of areal variations in the subsidence and rebound occurring over stressed aquifer systems, in conjunction with measurements of the hydraulic head fluctuations causing these displacements, can yield valuable information about the compressibility and storage properties of the aquifer system. Historically, stress-strain relationships have been derived from paired extensometer/piezometer i...

The water balance calculation and water quality are very important matters in the groundwater management. The water balance includes two parameters: input and output parameters. The input parameter is consisted from surface recharge (precipitation, irrigation return water, surfaces runoff recharge) and underground inflow (flow from adjacent aquifers). The underground inflow is an important fact...

A potential threat of pollution hydrolithosphere with petroleum and its products due to accidental technological leaks on a certain industrial object has been analyzed. The author's method mathematical modelling is described that allows perform an adequate dynamic lens in aquifer. Execution the resulting model forecast behavior conditions real geological hydro-geological cross-section.

Aquifer information carried by aquifer test data may be affected by the presence of a finite thickness skin around the wellbore. The mathematical treatment for an aquifer accounting for the skin zone can be characterized by five parameters, that is, the outer radius of the skin zone and the transmissivity and storativity for each of the skin and aquifer zones. Sensitivity analysis was performed...

Population growth, increasing urbanization and industrialization, mismanagement, climate change are accountable for the rising depletion pollution of groundwater worldwide. Consequently, water security, food environmental security in jeopardy, leading to a severe concern sustainable supply on Earth. The contamination groundwater, complex hidden resource, is difficult detect treat. Therefore, it...
