“…A similar impact of the bedrock composition to the water quality has been also described by Gamvroula et al (2013). It is commonly known that the ionic composition of water is the result of several factors during water-rock interaction (Hamzaoui-Azaza et al 2011).…”

“…In fact, modifications of the geochemical characteristics of saline waters can be due to water-rock interaction involving base exchange reactions with clay minerals, adsorption onto clay minerals and carbonate dissolution-precipitation (Thilagavathi et al 2012;Gamvroula et al 2013). In particular, the main factors controlling water mineralization seem to be the mineral dissolution of highly soluble salts and, of less importance, the ion exchanges.…”

Hydrochemical assessment of water quality for irrigation: a case study of the Medjerda River in Tunisia

2015

In order to characterize, classify and evaluate the suitability of Medjerda River water for irrigation, a hydrochemical assessment was conducted. It accounts for 80 % of the total Tunisian surface water. In this paper, hydrographical methods and PHREEQC geochemical program were used to characterize water quality of Medjerda River, whereas its suitability for irrigation was determined in accordance with its electrical conductivity (EC), sodium adsorption ratio (SAR) and sodium concentrations. It was established that the water samples were undersaturated with calcite, dolomite, aragonite, anhydrite, gypsum and halite except in one water sample which is supersaturated with carbonate minerals. The quality assessment of Medjerda River for irrigation purposes showed that some points belonged to the excellent-to-good and good-to-permissible irrigation water categories, while the remaining ones were classified as doubtful to unsuitable for irrigation making the river water use limited to plants with high salt tolerance. Moreover, based on FAO guidelines, almost all water samples may cause immediate salinity to gradual increasing problem but no soil infiltration problems except for two sampling points. However, immediate development or possible increasing of severe toxicity problems may be caused by the continuous use of this water for irrigation due to troublesome concentrations of chloride and sodium.

“…GIS and remote sensing have been used extensively by multiple researchers to assess the water quality all over the world, e.g. Aydi et al [3] and Ketata-Rokbani et al [18] in Tunisia, Shomar et al [19] in Palestine, Gamvroula et al [20] and Stamatis et al [21] in Greece, Kumar et al [22] in India, Baawain and Al-Futaisi [23] in Oman. The advancement of GIS and spatial analysis helps to integrate the laboratory analysis data with the geographic data and to model the spatial distributions of water quality parameters, most robustly and accurately.…”

Water quality assessment has always been a dominant part of environmental quality management. The present study involved the suitability assessment and mapping of groundwater quality for agricultural activities and drinking purposes in Rawalpindi and Islamabad area. A total of 22 samples were collected from borewells and open wells, and these water samples were further analysed for physical and chemical characteristics on the basis of which different indices were developed. Water quality index was calculated for overall water quality quantification from the perspective of human consumption. The results showed that a greater proportion exhibited poor quality for drinking due to overexploitation of groundwater resource, agricultural impact and direct release of contaminants. Further, evaluation of groundwater for its suitability for irrigation showed that majority of the groundwater was suitable for irrigation purposes.

The present study was carried out to assess the water quality of three lakes of Hyderabad, Telangana State, India viz., Hussain Sagar, Fox Sagar and Kattamysamma Lake by using water quality index (WQI). For this study systematic sampling has been carried out by collecting sixteen samples from each lake. The results were compared with water quality guidelines for drinking purpose (BIS 2012). The mean values of most water quality parameters were significantly higher than the accept limits in all three lakes. Ten important water variables were chosen to calculate Water Quality Index (WQI). All the three lakes fall under unsuitable for drinking purpose (>100) according to WQI scale.
