The groundwater is a substantial source of fresh water and has been used for various anthropogenic uses. The aim of this work is to investigate groundwater quality and type in kubaysa and AL-Waffa areas, Anbar, Iraq using multivariate statistics approach. The groundwater was sampled from ten wells for each region during the period from October 2018 to March 2019. The levels of T, TUR, pH, EC, TDS, DO, COD, TH, Na+, K+, Ca2+, Mg2+, NH4+, Cl-, F-, SO42-,, NO3-, HCO3-, S-2 and SiO2, were measured. The majority of the physicochemical parameters exceed the permissible guidelines. Pearson’s Correlation technique, multivariate statistical tools such as cluster analysis and principle component analysis were applied to determine the groundwater type. For Al –Waffa area, the EC had a positive strong correlation with TDS, Na+, Cl-. The TDS had positive strong correlations with NO3-. TH and Ca2+ possess a very good positive correlation between each other and positive strong correlations with SO42-. Sodium has positive strong correlations with k+ and Cl-. For the kubaysa area, the EC has positive strong correlations with TDS, Na+, K+ and Cl-. The TDS have positive strong correlations with TH, Ca2+, Na+, K+, Cl-, and SO42-. The piper diagram indicates that the groundwater types in AL-Waffa and kubaysa regions are Ca2+, Mg2+, SO42- and Ca2+, Mg2+,Cl-, SO42 respectively. The results showed unsuitable water for drinking purposes and need to be treated. The main finding of the current study is a suggestion to use the multivariate statistics technique in determining the groundwater classification type as an alternative method for the piper diagram.

Ecossistemas lênticos de pequeno porte respondem rapidamente às condições ambientais, influenciando a comunidade planctônica devido às flutuações bióticas e abióticas do corpo d’água. Este estudo teve como objetivo analisar os parâmetros físico-químicos e a identificação da comunidade planctônica (fitoplâncton, zooplâncton e bacterioplâncton) presentes no reservatório, correlacionando esses organismos em um ambiente oligotrófico. As análises foram realizadas mensalmente no período de julho/2014 a junho/2016. A análise de todos os parâmetros físico-químicos e biológicos foi realizados de acordo com metodologia oficial. Empregou-se ferramentas estatísticas multivariadas (ACP) e teste de Pearson para avaliar a correlação entre as variáveis abióticas e a biomassa total de cada grupo planctônico. Nesta pesquisa encontrou-se uma relação positiva entre as biomassas totais da comunidade zooplânctonica e fitoplânctonica, entretanto componentes do bacterioplancton, não foi significativo. Estes resultados indicaram que a predação e/ou competição não são relações ecológicas significativas entre as espécies zooplanctônicas e fitoplanctônicas presentes neste ecossistema oligotrófico, existindo assim uma relação favorável entre os grupos estudados. Desta forma, o desenvolvimento desses organismos foi influenciado pelas mesmas variáveis abióticas (manganês, dureza e temperatura), atuando de forma direta no estabelecimento de suas biomassas. A B S T R A C TSmall lentic ecosystems respond rapidly to environmental conditions, influencing the planktonic community due to the biotic and abiotic fluctuations of the water body. This study aimed to analyze the physicochemical parameters and identification of the planktonic community (phytoplankton, zooplankton, and bacterioplankton) present in the reservoir, correlating these organisms in an oligotrophic environment. The analyses were performed monthly from July/2014 to June/2016. The analysis of all physicochemical and biological parameters was carried out according to the conventional methodology. Multivariate statistical tools (PCA) and Pearson's test were used to evaluate the correlation between the abiotic variables and the total biomass of each planktonic group. In this research was found a positive relation between the total biomasses of the zooplanktonic community and phytoplanktonic. However, components of bacterioplankton were not significant. These results indicate that predation and competition are not significant ecological relationships between zooplanktonic and phytoplanktonic species present in this oligotrophic ecosystem, and there is a favorable relationship between the studied groups. In this way, the development of these organisms was influenced by the same abiotic variables (manganese, hardness, and temperature), acting directly in the establishment of their biomasses.Keywords: plankton, reservoir, abiotic factors.

A groundwater quality assessment has been carried out in northeast part of Anbar governorate in western Iraq. We analyzed hydrochemical parameters such as pH, electrical conductivity, total dissolved solids presence of ions to describe groundwater quality. The study area has the only confined aquifer within the geological formation extended in area. Values of groundwater hydrochemical parameters were ranged from (7) to (7.9) for ph, (1599) to (6800) µmhos/cm for electrical conductivity (EC) and (1048) to (4446) mg/l for total dissolved solids (TDS). The origins and types of groundwater in the area were of marine origin and MgCl2 water type while only (6) samples were of continental origin and Na2SO4 water type. Groundwater utilization indicated that it can't be used for drinking purposes, while few groundwater wells can be used for agricultural and (33) groundwater samples can be used for animal purposes. However, the nature of the soil in the area and the depth of the groundwater qualified water for agricultural uses in significant and wide ranges.

Supply Problem

<p><strong>Abstract</strong>: Presently the water-supply problem in the Asmara area has reached to a critical level. Using a GIS-based method this study identifies the spatial variability of the groundwater quality in the Asmara Area which could be an alternative source. The results show that, the Total Dissolved Solids (TDS), Total Hardness (TH), Chloride (Cl<sup>-</sup>), Nitrates (NO<sub>3</sub><sup>-</sup>), Calcium (Ca), Magnesium (Mg), Sulphate (SO<sub>4</sub>) and pH are 791.71, 569.12, 124.41, 64.46, 155.60, 46.64, 159.26 and 7.72 mg/L, respectively. Moreover, the zone map of the developed groundwater quality shows that the potable water without treatment covers about 35%, and the potable water in the absence of better alternate sources covers about 58% of the total area. The remaining, 7.04% of the total, falls under non-potable groundwater quality. The verification of the spatialanalysis demonstrates that the framework is the first one in Eritrea and could be used as a potential prediction for the assessment of the spatial groundwater quality in the countries with further verification results. Hence, the delineation of groundwater quality zones and establishment of a GIS-based database will easily help the decision makersto monitor and plan the utilization of the groundwater resources in the study area.</p><p><strong>Keywords: </strong>Groundwater quality; physicochemical parameters; GIS spatial analysis; framework</p>
