Abstract
The present work is devoted to evaluate the hydrochemistry of the groundwater in Quesna district, and study the extent of pollution through the determination of different types of chemical pollutants in groundwater samples which were collected from the shallow and deep wells, surface water samples were collected from the industrial effluents and from El khadrawaya drain
To fulfill the objective of this research the following activities were done:
- Review of Groundwater contamination concepts and previous relevant studies.
- Collection and analysis of the physical settings and hydrogeological conditions of the study area including its location, topography, land use, stratigraphy, Meteorological aspects, surface water system, groundwater aquifer system.
- Collection of groundwater and sewage water samples and its chemical analysis, comparison to standards and a description of the groundwater quality and sewage water quality in the study area.
- Chemical speciation of the groundwater using geochemical computer model “Visual MINTEQ”.
The study includes evaluation of water for using in different purposes as drinking and irrigation. Carrying out the chemical analyses for collected water samples these analyses included:
- Determination of the major ions Na+, Ca2+, Mg2+, K+ and trace constituents Ni, Cu, Cr, Mn , Zn and Fe .
- Determination of the anions Cl-, SO42- and NO3-.
- Determination of the organic constituent in the collected samples by determining Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD).
Piper diagram was used for classification of groundwater. All the groundwater samples are characterized by secondary alkalinity, Alkaline earth (Ca2+ + Mg2+) exceeds alkalis (Na++K+). Week acids (CO32- + HCO3-) greatly exceed strong acids (Cl- +SO42-).
All groundwater samples characterized by lower TDS which are reflected in low EC also.
All the groundwater samples show hardness less than 500mg/l, which is suitable for drinking water according to WHO(2006). About 23.2% of samples are moderately hard water, 38.4% of samples are hard and 38.4% are very hard. The high degree of hardness in the study area may be attributed to the disposal of untreated/improperly treated sewage and industrial wastes, so almost water are unsuitable for laundry uses.
Shallow and deep groundwater are polluted with metals “mainly Iron, Chromium and Nickel” because the infiltration from sewage system.
Shallow groundwater are more polluted than deep groundwater, this is because shallow groundwater is much vulnerable to pollution than groundwater.
