Hydrogeochemical analyses were conducted on groundwater sampled from the Saloum aquifer, in southern Senegal. The objective was to identify the chemical processes that control hydrochemistry and to assess the quality of groundwater for determining its suitability for drinking and agricultural purposes. Water samples were collected from 79 wells during the dry season in May 2012, and were subjected to analysis for chemical characteristics (major ions), pH, electrical conductivity (EC) and total dissolved solid (TDS). The dominant hydrochemical facies observed for the groundwater samples are NaCl and CaHCO3. Gibbs plot depicts predominance of rock water interaction and evaporation processes controlling the water chemistry. Percentage of Na+, Residual Sodium Carbonate (RSC), Total Hardness (TH) and Sodium Adsorption Ratio (SAR) values were calculated. The results were compared with the standard guideline values recommended by the World Health Organization and agricultural water standards. The TDS in groundwater is less than 1200 mg/L and SAR values are less than 10. RSC values overall are less than 1.25 meq/L. Results show that the groundwater in the area has generally a low hardness and is fresh (95%) to brackish. The majority of groundwater samples are appropriate for domestic uses. The indexes for water irrigation compared with standard limits revealed that most of the Saloum groundwater samples fall in the suitable range for irrigation.

The present study depicts the hydrochemical processes controlling the variance in the hydrochemical facies for sixteen samples obtained from Habbaniya Lake. The water samples were analyzed for the major ions (cations and anions) data in mg/l, total dissolved solids in mg/l, pH unitless, electrical conductivity in μS/cm, and temperature in °C. Piper trilinear (three-line) diagram indicates the overall of samples belongs to class 1 (Ca2+, Mg2+, Cl-, SO42-), category I (SO42- - Cl- and Ca2+ - Mg2+), and permanent total hardness (calcium chloride type). The contribution of cations in the Habbaniya lake was almost the same percentage (no dominant cation), while the SO42- is the dominant ion of the surface water in the Habbaniya lake. The analytical values showed that overall the samples were freshwater and low enrichment salts within the permissible limits of the World Health Organization standards. Irrigation parameters and water quality index were calculated for samples to assess water for agricultural and drinking uses for the inhabitants of the study area. The basic exchange is the exchange of Na+ and K+ ions in water with Mg2+ and Ca2+ ions in materials which is exposed to weathering.

AbstractThe study examines the water quality of Shahdadkot, Qubo Saeed Khan and Sijawal Junejo talukas of Qambar Shahdadkot District, less affected by industrial contamination. A total of 38 groundwater samples were collected and analysed for 28 parameters. The results indicated that 57.89% samples were not suitable for drinking purpose with total dissolved solids above than maximum permissible limit of World Health Organization (WHO) (1000 mg/L). The pH, total phosphate, orthophosphate and nitrite were within WHO limits. The concentration of essential metals more than half samples, fluoride in 60.52% and heavy metals 0–50% were contaminated higher than permissible limits of WHO. The statistical analysis of water quality parameters was also carried out to evaluate coefficient of determination among the parameters, cluster analysis and principal component analysis. Water quality determined for irrigation based on Kelly index (KI), sodium percentage (Na%), chloride–sulphate ratio, sodium adsorption ratio, permeability index (PI), chloroalkaline indices 1 (CAI-1), residual sodium carbonate and chloride bicarbonate ratio indicated that samples (55 to 100%) could be used for irrigation purposes. The consumption of water with high concentration of salts and fluoride above the permissible limits may be a cause of a number of diseases in the area.

The occurrence and distribution of arsenic and 23 other trace elements have been investigated in groundwater from Comandante Fernández Department in the Central region of Chaco Province, Northern Argentine. The arsenic concentrations samples ranged between 0.7 to 1990 µg L−1; 91% (n=45) exceeds the 10 µg L−1 World Health Organization (WHO) provisional standard limits for drinking water. Fluorine was detected in 31% of groundwater samples. Furthermore, there was found a significant correlation between As and F (r2=0.50), indicating an association in the prevalence of both elements. In addition, about 78%, 31%, 16%, 13%, and 4.5% of groundwater samples had, respectively, B, Fe, Al, Mn, and Sb exceeding Código Alimentario Argentino (CAA) guideline values. In contrast of the previously values descript, the corresponding to Cr, Be, Ni, Pb, Ag, Se, and Zn were found below the quantification limit. The presence of As and trace elements in groundwater represents an important issue because it can cause a public health problem.

The Impact

In order to assess the quality of surface water of Boudaroua Lake, located in the Moroccan Pre-rif.The water quality parameters was used to evaluate the potential presence of toxicity of this ecosystem. To this end, samples and hydrochemical analyzes were carried out for five permanent stations around the Lake, during the study period (July 2019, October 2019, January 2020). The study was based on 11 parameters, namely, turbidity (TUR), dissolved oxygen (O2), total hardness (DT), calcium (Ca2+),magnesium(Mg2+), sodium (Na+),potassium (K+), ammonium (NH+4), chloride(Cl−), sulfate( SO2−4), nitrate (NO-3)were considered. The results obtained of these physicochemical parameters have been compared with the Moroccan standard (MS) for surface water and with the World Health Organization (WHO). The results indicated that the values of the physicochemical parameters varies significantly seasonally due to precipitation rate variation. In addition the impact of Agricultural pollution resulting from the excessive use of fertilizers that enter the lake through waterways, such as ammonium NH+4, and dissolved oxygen (O2) its value reaching respectively 1.09 mg/L ,12 mg/L remains above standards (MS) and (WHO) which could harm the ecosystem of the lake.

Water is a basic need of life, and more so, potable water is critical for healthy living. Shallow boreholes are now popular as the main source of drinking water in the Yenagoa metropolis due to the contamination of surface water and rainwater caused by poor management of wastes and crude oil facilities in the area. However, there are concerns about variations in the quality of groundwater across communities in the Yenagoa metropolis. Thus, this study assesses the spatial variations of physicochemical parameters of groundwater samples from 50 boreholes in the area, and results compared with recommended standards prescribed by the World Health Organization (WHO). Parameters analyzed were pH, electrical conductivity (EC), salinity, total dissolved solids (TDS), nitrate, chloride, sulfate, total alkalinity (TA), total hardness (TH), calcium, magnesium, sodium, potassium, and iron. Global Information System (GIS) technology was adopted to present the groundwater quality in respect to each physicochemical parameter, in thematic maps. The maps showed that groundwater was slightly acidic in most communities in Central and Northern Yenagoa like Ekeki, Swali, Akaba, and Okolobiri. In communities like Ogbogoro, Ekeki, Azikoro and Yenegwe the EC was higher than the standard permissible value according to the WHO. A very high concentration of iron was observed across all communities except a few like Nedogo, Okolobiri, Tombia, Gbarantoru, Ayama, Famgbe, and Ikibiri having iron-free groundwater. Concentrations of TDS, calcium, magnesium, nitrates, sulfates, potassium, and sodium were within permissible limits across all communities. Communities like Ayama-Ijaw, Obololi, Ikibiri, Ikudu, Bomodi, Tombia, and Akaibiri had good groundwater while Ekeki, Famgbe, Yenaka, and Kpansia boast of excellent groundwater quality, and other areas had either poor or unsuitable groundwater for consumption. Treatment is recommended for parameters with higher concentrations than the standard value stipulated by the WHO.

The ongoing degradation of the water quality of central Maharashtra’s basaltic aquifer is of great concern for different authorities and agencies involved in the water sector in the Maharashtra, India. The Kham river, which is one of the major tributaries of the Godavari river, receives all domestic and industrial waste water from the Aurangabad city. The river, with no natural flow in the dry season, is extensively used for irrigation. In order to evaluate the quality of river and groundwater in the study area, eight river water and forty groundwater samples along right and left bank of the Kham river were collected and analyzed for various parameters. Physical and chemical parameters of the river and groundwater such as pH, TDS, EC, SO4, NO3 and heavy metals like Pb, Cr, Cd, Zn, and Cu were determined. The results show that the river and groundwater of the area is generally unfit for domestic uses. Most of the physico-chemical parameters and heavy metals in the river and groundwater samples have higher value than the World Health Organization (WHO, 2006) and Bureau of Indian Standards (BIS, 2003) guidelines.
