“…In the present study, groundwater monitoring has been taken up for effective assessment through understanding of hydrogeology, geology and waterchemistry of the watershed. The collected basic data is used for the preparation of the groundwater flow and mass transport model for quantitative assessment of impact of anthropical influence on contaminant migration in the watershed [BOUGHERIRA et al 2014].…”

The potentiometer area in the Annaba basin, covering an area of 264 km2, has declined considerably since 1995. The analysis of the chronological hydrographs (1991–2009) of the piezometric observations shows that this decline is related to about twenty years (20 years) drought that began in 1991. To synthesize hydrological data and study regional changes in aquifer interactions caused by changes in discharge, and determine the contamination of aquifers by salty intrusion in coastal areas, and making forecasts by the year 2023, a multi-layered transient model as well as a solute transport model has been developed. The groundwater flow was modelled using the finite difference method with a horizontal dimension of 500 × 500 m for the cells. The model consists of two layers, the first corresponding to the alluvial phreatic aquifer and the second to the deep confined aquifer, and is calibrated against the steady state groundwater heads recorded before 1996. Model verification was done by history matching over the period 1991–2009. Under steady-state conditions, the correspondence between simulated and observed water levels is generally good (average difference of 0.4 m). For the deep aquifer, the simulated time-series hydrographs closely match the recorded hydrographs for most of the observation wells. For the alluvial aquifer, the recorded hydrographs cover only a short time period, but they are reproduced. The model indicates that groundwater pumping induced a decrease in natural discharge, a downward leakage in most of the basin and a continual water-level decline. The model has also been applied to the analysis of recharge impact. Simulating the behaviour of the system over the period 1991–2009 without pumping indicated small changes in hydraulic head. These results show that the groundwater reservoir has a low recharge, but excellent hydraulic properties. A solute-transport model was used to study aquifer contamination from salty intrusion in coastal sectors; it was extended to the year 2023 by simulating an optimistic hypothesis that maintains present pumping until 2023. The model indicates that the head decrease of the alluvial phreatic and deep confined aquifers will be 4 m and 5 m respectively. The solute concentration in the deep confined aquifer will increase from 1 gꞏdm−3 (prior 2009) to 5 gꞏdm−3 in 2023.

“…(Kundzewicz et al, 2007). The potability of surface water has greatly been affected and contaminated by the untreated domestic and industrial disposals (Bougherira et al, 2014). Indiscriminate disposal of domestic and industrial solid waste and liquid effluents can directly enter into the run-off water and causes surface water pollution which than broadly affect the aquatic and surrounding natural ecosystems.…”

In this research work, the author has studied the quality parameters and the effect of industrial pollutantson the quality of surface water of Agyara Dam, Alwar (Rajasthan). Agyara Dam is a surface water reservoirsituated near the Agyara village of Ramgarh tehsil (Alwar) and it is surrounded by number of industrialunits including Matsya Industrial Area (MIA). The water of Agyara Dam has greatly been affected andpolluted by the industrial solid waste and liquid effluents. The surface water specimens were bottledthroughout the period of October-December, 2021 and analyzed by the numerous quality parametersfollowing the standard operating procedures (SOPs). The mean of the quality parameters has showed theconsiderable variations and indicated that the surface water of Agyara Dam has been polluted due to theindustrial activities near it. The water of Agyara Dam was found to be unsafe for human drinking anddomestic purposes as most of the quality parameters do not imitate with the standards of Bureau of IndianStandards (BIS).

The current work was aimed to characterize and defining appropriate treatment processes for various types of raw wastewaters. The fresh wastewater samples were collected from slaughterhouse (SWW), tannery (TWW), municipal (MWW), municipal landfill leachate (MLL), and dairy (DWW). The collected samples were analyzed for temperature, pH, electrical conductivity, turbidity, total alkalinity, total hardness, biological and chemical oxygen demands, suspended and dissolved solids etc. Commonly, MLL contained low biodegradability ratio; while SWW, MWW, and DWW had high biodegradability ratio of greater than 0.5. TWW regarded as strong alkaline because pH values were greater than 10. Physical, chemical and biological treatment processes were explained and suitable treatment methods were complemented with the wastewater type. It can be concluded that generally physical-chemical techniques were fit with old landfill leachate and tannery wastewaters; whilst biological treatment methods with adsorption were adequate for SWW, MWW, and DWW and the effluents match the quality of irrigation water quality.
