Assessment and Mapping of Groundwater Quality for Irrigation and Drinking in a Semi-Arid Area in Algeria

Abstract

Water resources are a major concern in dry or semi-dry countries. They are crucial to the development of human, economic and social activities [Ragab et al., 2002b;Williams., 1999;Misra., 2014;Wang et al. 2017]. Algeria has adopted a new policy to protect and safeguard water resources [Negm et al., 2020;Qadir et al., 2007], as population and urbanization increases, industrial units and farm land have resulted in the degradation of groundwater and surface water quality, combined with a very significant decline in the groundwater resources, the only water reserves for the supply of populations.It is critical to understand the groundwater quality because it is a key mark of its suitability for human consumption, agriculture, and/or industry. In recent years, there has been a worldwide increasing concern for water quality. Several studies [Khan et al., 2020; Rao et al., 2012;Babiker et al., 2007] were conducted to assess the quality of groundwater.Groundwater chemistry has been used as an instrument for evaluating the quality of water for human use and irrigation.

The Zonality of Underground Water Supply Sources for Pastures in the West Kazakhstan Region

“…The depth of the surveyed 297 wells varies between 1.8-26 m and the depth of 46 boreholes varies from 12 to 80 m. The flow rates of wells (0.02-1.8 dm 3 /s) and boreholes (0.4-2.6 dm 3 /s) in the permeable modern Aeolian horizon are mainly sufficient for the organization of watering points. The mineralization of water in the permeable modern Aeolian horizon is more often low with fresh (0.11-0.9 g/ dm 3 ) and brackish (1.1-9.36 g/dm 3 ), water generally promising for the water supply of various livestock types. In the permeable modern Aeolian horizon, drilling of shaft wells can be recommended for water supply.…”

“…For groundwater in the territory of Kosovo, the groundwater level was monitored and a hydrogeological computer model designed to determine the source protection zones was created [Osmanaj et al, 2021]. Data on the assessment and mapping of groundwater quality for water supply and drinking in the semi-arid region of Algeria show the characteristics of water quality indices based on hydrochemical analysis data [Azlaoui et al, 2021]. There is a publication on the problems of groundwater zoning by various indicators [Davybida et al, 2018].…”

Contribution to Geospatial Classification by Using Quality Indices for Irrigation Water in Arid Zones, Case of Ouargla Region, South East Algeria

“…This evaluation is based on an overall qualitative quantification of the individual classification of each of the wells according to all the indices considered in this study [30]. For this purpose, we designate by the (+) sign the permissible irrigation water together with good and excellent qualities and by the (-) sign for poor and bad quality waters.…”

Evaluating Groundwater Potability and Health Risks from Nitrates in the Semi-Arid Region of Algeria

“…Ain Ouassera, located in the steppe region of central-northern Algeria, heavily depends on its underground aquifers for a variety of needs, including industrial, agricultural, and residential purposes. The Lower Cretaceous aquifer stands out for its significant hydraulic potential and accessibility (ANRH, 2014; Azlaoui et al, 2021), playing a crucial role in the region's water supply. However, the increasing water demand, coupled with challenges posed by climate change, has led to a decrease in aquifer piezometric levels and a significant deterioration in water quality, notably due to excessive mineralization and notable nitrate pollution.…”
