“…Wilcox (1955) diagram (Fig. 6) is widely used and is especially implemented to classify groundwater quality for irrigation (Ebraheem et al, 2012;Banoeng-Yakubo et al, 2009;Ganyaglo et al, 2011;Swarna Latha and Nageswara Rao, 2012;Mtoni et al, 2013). The calculated SAR values range from 0.86 to 7.55 in groundwater in the study area and almost all samples fall into excellent class (Table 3).…”

The overexploitation of groundwater and groundwater salinization cause quantitative and qualitative degradation of the water resources. The objectives of this research are to identify and investigate the extent of seawater intrusion and nitrate pollution into the coastal plain of Marathon in Eastern Attica, Greece. In the frame of this, 25 groundwater samples were collected in October 2014 from the study area and analyzed regarding the main parameters that indicated salinization of the aquifers. Specifically, water chemical analyses were carried out and statistical analyses regarding spatial distribution were performed. The results demonstrated increased values of the parameters which can be associated with seawater intrusion. Considering and evaluating the results from the chemical analyses it is obvious that seawater intrusion takes place in the area. Furthermore, the average concentration of NO3was 44.16mg L -1 and this can be attributed to overexploitation of coastal aquifer for agricultural activities. ΠερίληψηΗ υπεράντληση των υπογείων υδάτων και η υφαλμύριση οδηγεί σε ποσοτική και ποιοτική υποβάθμιση των αποθεμάτων νερού. Οι στόχοι αυτής της μελέτης είναι να εντοπιστεί και να διερευνηθεί το φαινόμενο της υφαλμύρισης και νιτρορύπανσης στην παράκτια πεδιάδα του Μαραθώνα στην Ανατολική Αττική. Για το σκοπό αυτό, 25 δείγματα υπόγειων υδάτων συλλέχθηκαν κατά την περίοδο του Οκτωβρίου 2014 από την περιοχή μελέτης και αναλύθηκαν ορισμένες παράμετροι που σχετίζονται με την υφαλμύριση των υδροφορέων. Συγκεκριμένα, διεξήχθησαν χημικές αναλύσεις υδάτων, στατιστική επεξεργασία και χάρτες χωρικής κατανομής. Τα αποτελέσματα έδειξαν αυξημένες τιμές των παραμέτρων που μπορούν να αποδοθούν στη διείσδυση θαλασσινού νερού. Από την ανάλυση και κατανόηση των χαρακτηριστικών της ποιότητας των υπόγειων υδάτων του Μαραθώνα, είναι σαφές ότι η περιοχή βρίσκεται υπό καθεστώς θαλάσσιας διείσδυσης. Επιπλέον, η μέση συγκέντρωση NO3 ήταν 44.16 mgL -1 και αυτό μπορεί να αποδοθεί στην υπερεκμετάλλευση των παράκτιων υδροφορέων για γεωργικές δραστηριότητες.

“…The process is cost effective process, with non-hazardous end products (Ahmed et al, 2004). According to Gupta et al, (2000) and Duffus et al, (2002), the major groups of microorganisms that have been implicated in heavy metal remediation are bacteria (such as Anthrobacter, Bacillus sp, Citrobacter, Cupriavidus metallidurans, 37 Cyanobacteria, Enterbacter cloacae, Alcaligenes, Sphinganonas, Rhdococcus, Mycobacterium and Arthrobacter) and fungi (such as Aspergillus tereus, Penicillium chrysogeum, Candida and Rhodotorula mucilaginosa). Beside bacteria and fungi, certain protozoa, such as Euplotes mutabilis and algae, such as Oscillatoria sp, Chlorella vulgaris and Chlamydomonas sp have been reported to possess metal reducing capabilities (Ramasamy et al, 2006).…”

This work assessed the presence of heavy metals in water contaminated with petroleum products in Keffi Local Government Area. Two water sampling station were selected based on the stratified method of sampling of Antau River. Station A is located along Federal Government College Keffi popularly known as Antau Bridge where Agricultural and mechanical activities, with sales of petroleum product take place. Station B was located at Dadin Kowa known as Gada Manu where human activities such as bathing and washing takes place which served as control. The distance between stations is 1km. The procedural plan of this study was monthly sampling of water from both Stations. Materials such as funnel, sampling container, distilled water, conical flask, filter paper, 50ml polypropylene centrifuge tube, cooler were used. Heavy metal concentration was determined using X – ray Fluorescent Spectroscopy (XRF) at the Center for Energy Research and Training (CERT), Ahmadu Bello University Zaria. The water parameters of the four samples were determined using the Extech instrument. The result on Physico – chemical parameters revealed the values obtained from contaminated water samples to be pH (7.31), Dissolved Oxygen (1.14), Electrical Conductivity (8.22), Total Dissolved Solid (4.13), Temperature (27.45) and Salinity (0.091) while the controlled Station at point B were pH (7.43), DO (7.35), EC (3.14), TDS (1.54), Temperature (26.75), Salinity (0.o94) respectively. From the result obtained, the heavy metal contaminated samples had the following values: Mg (29.31±), Al (218.69±), Si (230.12±), S (1153.65±), Cl (54.25±), Ca (106.56±), Ti (23.66±), Cr (3.15±), Fe (15.92±), Cd (7.54±). For the control sample at point B, the following values were obtained: Mg (27.49±), Al (223.71±), Si (243.21±), S (94.84±), Cl (23.52±), Ca (28.44±), Ti (32.99±), Fe (16.63±), Cd (7.67±) respectively. The P-value was 0.8105 (p>0.05) for the water quality parameters while for the concentration of heavy metal P-value was 0.2054 (p>0.05). This implies that there was no significant difference between the concentrations of elements. However, the concentration values of heavy metals in the contaminated water at Station A and control water samples at Station B were higher than the World Health Organization values (Standard) for drinking water

“…groundwater is resorted to as it is an important resource for drinking, domestic use, and irrigation of crops and livestock, so managing this resource is critical to meet the increasing water demand. Natural factors)such as rock type, groundwater velocity, geochemical processes, soluble salts, the quality of water recharged into aquifers, and human-induced factors, such as agricultural operations and industrialization, influence the physical and chemical properties of groundwater [2]. The study of water's hydrochemical properties can aid in determining the mechanics and type of chemical interactions that occur between water and water-bearing rocks, allowing for better and easier protection and the use of water for drinking and irrigation.…”

Groundwater is necessary to ensure the safety of Mandali's water supply. Groundwater samples were collected from various parts of the city for this study. Two aquifers have been identified: the first is a free bed made up of Quaternary deposits. The second is the primary bed that conveys water, belonging to the Bai Hassan Formation. Nineteen groundwater samples were collected from wells and examined for physicochemical parameters in the current study during October 2021. Samples were analyzed for main cations Ca2+, Mg2+, Na+, and K+; anions HCO3- , SO42- , Cl- and NO3-, pH, Electrical Conductivity, and Total Dissolved Solids. Results indicated that the Samples water is neutral to slightly alkaline. The TDS classifications show that the groundwater samples are classified as fresh to slightly fresh water. All water samples are severely mineralized, except sample W17 which is highly mineralized due to the water feeding from the deep aquifer of Bai Hassan formation. Dominant cation is Na+ followed by Ca2+, Mg2+ then K+, whereas dominant anion SO42 ̶ followed by Cl¯ then HCO3¯. The water type of 8 samples 42% is NaCl type, seven samples 37% is MgSO4 type, three samples 16% is Na2SO4 type, and 1 sample 5% is CaSO4. The diversity in water is because the sediments of the Quaternary age derived from neighboring formations such as Fatha and other formations. According to Piper's diagram, Groundwater samples are mostly earth alkaline water with an increased amount of alkali, high sulfate and chloride. The groundwater in the study area has a wide range of WQI ranging from excellent (W17) while classified as good water (W1, W3, W4, W5, W6, W7, W8, W9, W11, W12, W13, W14, W16, W18, W19) and classified as Poor water (W2, W10, W15) because of the high values of WQI values computed.
