Abstract The study presents the possibility of using geostatistical methods for monitoring groundwater quality. Poland is one of the largest copper producers in the world. However, the extraction and production of copper requires constant care for the natural environment. Reservoir Żelazny Most which is situated in South – Western Poland was designed to store flotation tailings out of nearby copper mines. It is one of the biggest industrial dumps in the world. The reservoir stores huge amounts of tailings and industrial water. Water migrating from dump to groundwater could be a potential source of contamination with chlorides, sulphates, heavy metals, and other hazardous substances used in ore separation process in the copper mining industry, like detergent and phenols. Monitoring system around Żelazny Most dump, which was designed to track harmful substances concentrations in groundwater, contains measuring wells and piezometers. They are used to collect groundwater samples for chemical analyses. The idea of the study was to integrate information provided by chemical analyses and geoelectrical measurements by cokriging method, utilizing correlation between electrical resistance of the soil solution and total dissolved solids concentration in groundwater. This enabled to obtain spatial distribution of total dissolved solids concentrations in groundwater at the part of eastern foreground of Żelazny Most dump.

In order to research the groundwater quality of the Taikang Formation in Tertiary in west of Daqing Oilfield, resistivity logging data of 140 wells in the study area were analyzed to forecast the groundwater total dissolved solids (TDS) distribution of the plane. When the resistivity logging value (Rt) of the Taikang Formation in Tertiary is above 45Ω.m and its corresponding value of Formation water TDS is below 1000 mg/L, the quality of groundwater accords with life standards for drinking. The south area of Hongweixing well area and the east of Xishuiyuan well area, including Ranghulu, Qianjincun, Dulitun and Nanshuiyuan well area are favorable for high quality groundwater. The research provides the evidences to evaluate the groundwater quality in west Daqing Oilfield and determine specific well location, improving the efficiency of exploring the underground drinking water.

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.

In this present study, the geology, relief, spatial variation and challenges of groundwater quality has been carried out, using Kriging Model. The methodology employed was drawn from primary and secondary data sources. Detailed chemical analyses for some of the parameters of the groundwater were done on a total of twenty-one (21) samples of both hand-dug wells and borehole waters collected during the full field investigation. In the laboratory analysis, the AAS and XRF machines were used to analyze eight (8) samples, namely: Temperature, pH, Total Dissolved Solids (TDS), EC, Total Hardness, Lead, Iron, and manganese. The results of the chemical analyses which were akin to groundwater geochemical characterization based on the ranges of parameters shows that the value of pH in the study area ranges from (6.53 to 7.30), The Total Dissolved Solids ranges between (0.00 to 24.00), the EC has concentrations between (0.06 to 22.00) which was also around the permissible units of both SON and WHO. Total Hardness of the samples of the area run from lowest concentrations of (60 to 3915) which does not exceed the SON permissible unit, but exceed the recommended limit of WHO. The corresponding limited ranges of iron and manganese ranges from (0.53 to 15.24 and 0.4 to 3.35),the concentrations of Lead from lowest to highest were (0.74 to 2.31), both of which defy the recommended limits of WHO (0.05) and that of SON (0.01). Based on this, it was concluded that some of the groundwater sources assessed are safe for human consumption. If the practice of consuming groundwater without treatment continues, it may lead to health hazard.. ANOVA-F (One Way) was adopted in testing the hypothesis (Calculated F=6.63 while Critical F=2.16). The study recommended that appropriate measures should be taken to bring the higher concentrated parameters to desired levels.

Abstract The present work evaluated the groundwater quality index (GWQI) depending on some physicochemical analyses of thirteen groundwater samples in the Zubair district in Basra Province, Iraq. The collected groundwater samples were subjected to an extensive physicochemical analysis to evaluate the characteristics of water for drinking purpose according to Iraqi standard. For calculating the (GWQI), twelve water quality parameters were considered; turbidity, pH, chloride, total dissolved solids, total hardness (TH), electrical conductivity (EC), sodium, sulphate, phosphate, calcium, nitrate, and magnesium. The analysis of the results reveals that all the samples surpassed the portability of drinking water limits. High values of the (GWQI) in the obtained groundwater samples could possibly be caused by the higher values of electrical conductivity, total hardness, chloride, total dissolved solids and sodium within the groundwater. The calculated GWQI values ranged from 73.36 to 595.92. The pollution index (PI) was calculated for the study area with values ranged from 2.97 to 8.26. Correlation coefficients amongst the chosen water parameters exhibited some strong relationships. Finally, the analysis shows that the groundwater in this particular area needs to be treated before its consumption, and in addition, it usually needs to avoid the hazard of contamination. Principal component analysis (PCA) and cluster analysis (CA) indicate that the acquiring-data from groundwater samples are explained 90.5 % of the variance in the data with a four-component system that explains a large portion of the total variance of collected data.

Five saline lakes near Marchagee. with salinities ranging from 10-71‰, were sampled every two months between March and September 1979. The lakes contained faunal assemblages of 6-13 invertebrate species; only two species were common to all lakes. Fish (Pseudogobius olorum) were found in one salt lake. Austrochiltonia subtenuis was recorded at a salinity of 71‰ twice the salinity it was previously thought to tolerate. Pseudogobius olorum was collected at a salinity of 55‰ and is the second species of fish to be collected from highly saline Australian lakes. Mytilocypris mytiloides was collected at a total dissolved solids concentration of 45‰ a much higher level of salinity than it tolerates in eastern Australia. Necterosoma pensillatus was found at a salinity of 10.5‰ the lowest yet recorded for the species.

The rise in the cost of production of beer due to increasing demand for freshwater and high cost of treating wastewater, motivate research interests in resource management in beer production. This study determines and reduces the concentration of the contaminants in the wastewater samples collected from a brewery in Nigeria, to reduce freshwater demand and to save the cost of operation through wastewater reuse using pinch technology. The wastewater samples were analysed for the concentration of Chemical Oxygen Demand using standard procedures. The Total Dissolved Solids were measured using pH-EC-TDS metre. Water Cascade Analysis was used to evaluate the minimum freshwater demand and wastewater generated to design the maximum wastewater recovery network for minimum freshwater demand in the process. The results showed that for 41.54 t/hr of both the freshwater and wastewater used in the brewery operations, the Chemical Oxygen Demand concentration ranged between 0 – 74,775 ppm and the Total Dissolved Solids concentration ranged from 0 – 2,008 ppm. However, with the application of Water Cascade Analysis, the freshwater and wastewater flow rates reduced to 19.88 t/hr based on Chemical Oxygen Demand concentration and 21.54 t/hr based on Total Dissolved Solids concentration. The freshwater saving per annum based on the concentrations of Chemical Oxygen Demand and Total Dissolved Solids were ₦346,560,000:00 ($962,666.67) and ₦319,840,000:00 ($888,444.44), respectively. The study concluded that the application of Pinch Technology to brewery operation is viable because of its capacity to reduce freshwater demand and wastewater generation.

Drinking Purpose

Water is prime requirement for living beings to live on the planet earth. In the modern developmental activities, agricultural practices, industrial purposes and need of drinking water for increasing population resources of fresh water are depleting fast and creating crisis of water availability per capita. Haryana is an agricultural dominant state with requirement of water whole year for irrigation purpose. Besides agriculture demand water is also used in industrial purpose as well as increasing drinking water requirement for increasing population in the state. In the present study groundwater quality in Pehowa block which covers 548 sq. km. area in Kurukshetra district of Haryana state, India have been studied for drinking purpose. Nine groundwater samples were collected from different parts of the block in double capped plastic bottles. Groundwater samples were analyzed using field water testing kit prepared by Tamil nadu Water Supply and Drainage Board, Chennai for twelve chemical parameters-pH, alkalinity, hardness, chloride, total dissolved solids, fluoride, iron, nitrite, nitrate, ammonia, phosphate and residual chlorine. Results of chemical analysis of groundwater samples shows that range of pH 7- 8, alkalinity 230-420 mg/l, hardness 100-280 mg/l, chloride 30-100 mg/l, total dissolved solids (TDS) 432-924 mg/l, fluoride 0.5 - 1.5 mg/l, iron nil in all groundwater samples, ammonia nil - 2 mg/l, nitrite 0.2- 0.5 mg/l, nitrate 45-75 mg/l, phosphate nil in all groundwater samples, and residual chlorine nil to 0.5 mg/l. The study shows that groundwater is non-potable at Bherian (nitrate 75 mg/l), Gumthala (nitrate 75 mg/l, ammonia 2 mg/l), Thana (nitrate 75 mg/l), Ramgarh (nitrate 75 mg/l), Mohanpur (nitrate 75 mg/l), Sarsa (nitrate 75mg/l), Tikri (ammonia 1 mg/l, residual chlorine 0.5 mg/l). Groundwater is potable in one groundwater sample taken at Bodha with respect of all the twelve chemical parameters of drinking water. The study is highly useful for monitoring groundwater quality for drinking purpose in the study area.

This paper presents the results of a geophysical investigation of groundwater quality in parts of Akwa Ibom State, Southern Nigeria. A total of 11 vertical electrical soundings (VES) was carried out in the study area using the Schlumberger electrode configuration. The results of the interpretation show that the area comprises 4 geoelectric layers. The third layer constitutes the major economic hydrogeological unit in the area and has resistivity of between 50.3 Ωm and 2088.9 Ωm and thickness of between 36.8 m and 149.0m respectively. The groundwater quality was assessed through estimates of the electrical conductivity and total dissolved solids in water. The conductivity ranges from 74.5 to 604.4µS/cm with an average value of 244.0µS/cm while the TDS values range from 47.7 to 386.8 ppm with an average value of 156.1 ppm. Based on these values, which are within the permissible limits, the water is considered to be fresh and suitable for drinking and other domestic/agricultural usages. The results show excellent correlation between the estimated TDS and the Dar-zarrouk parameters (longitudinal conductance and transverse resistance) on one hand and the aquifer bulk resistivity on the hand which demonstrate the ease of deriving TDS from surface resistivity data.
