Assessing the Groundwater Quality in the Liwa Area, the United Arab Emirates

Abstract

Last period groundwater quality raises big concerns all over the world since it is a limited source of drinkable water and for agricultural and industrial use. While the suitability of the groundwater of Liwa aquifer (Abu Dhabi Emirate) for agricultural use has been previously partially studied, not all the water parameters have been taken into account. Therefore, in this paper, we propose the study of 42 concentrations series of 19 groundwater parameters. We test the hypothesis that the water parameters series recorded at different locations are similar and group the samples in clusters. The main parameters that determine the differences between the clusters are determined by Principal Component Analysis (PCA). Finally, we use a quality index for assessing the water suitability for drinking. The conclusions emphasize the necessity of using more than one technique to evaluate water quality for different purposes and to cross-validate the results.

Assessment of Metals Concentrations in Soils of Abu Dhabi Emirate Using Pollution Indices and Multivariate Statistics

“…Literature survey reveals different multivariate GIS approaches for determining the heavy metal contamination in agricultural soil [8,[43][44][45][46][47][48][49][50] in many parts of the world, but only a few articles are focusing on the analysis of the metals concentrations in soils [38], sediments [51][52][53] and water [54][55][56][57], in the United Arab Emirates. Apart from the mentioned articles [38,[51][52][53][54][55][56][57], only one study [58] presents the soil characteristics in the Eastern Arabian Desert Region using as investigation tools the ICP-OES with GIS Mapping.…”

Geospatial Assessment of Groundwater Quality with the Distinctive Portrayal of Heavy Metals in the United Arab Emirates

“…This infringement of this precious resource can be attributed to its nearest obtainability with partial efforts and spatial obstinacy. Aquifers at specific demand locations are being drained, and this state may lead to deprivation of this indispensable resource unless allayed [2]. The hydraulic conductivity and permeability of the rocks depend on the rocks' porosity [3].…”

Assessing Water Quality by Statistical Methods

“…In this context, the Special Issue with the title "Assessing Water Quality by Statistical Methods" addressed topics related to groundwater vulnerability [1][2][3][4], estimating water quality parameters in natural and artificial lakes and gulfs [5][6][7], investigating the causes of Rivers pollution [8][9][10], and proposing new tools for estimating the regional extent [11] and mitigating the effects of high precipitations on the water quality [12].…”

“…In the same idea of evaluating the groundwater quality, in another part of the worldthe United Arab Emirates-the article [3] proposes a combined approach involving a multivariate statistical analysis and water quality indices' use. The study relies on a database containing 42 concentration series of 19 water parameters collected in the Liwa area.…”

“…Finally, a quality index for assessing the water suitability for drinking was computed in two scenarios. The authors emphasized the necessity of using more than one technique to evaluate water quality for different purposes and to cross-validate the results [3].…”
