Groundwater quality with respect to nitrate, major inorganic constituents, stable isotopes, and tritium was assessed in the agricultural Tangshan region in the Hai He River Basin of the People’s Republic of China and compared with three regions in the U.S.: the Delmarva Peninsula of Delaware, Maryland, and Virginia; the San Joaquin Valley of California; and the Sacramento Valley of California. The China and U.S. regions are similar in size and land use, but have different climatic conditions and patterns of water use for irrigation. The Tangshan region has been in agricultural production for a much longer time, probably several centuries, than the three U.S. regions; however, the widespread use of synthetic fertilizers and other soil amendments probably started at a similar time in all four regions. In all four regions, median nitrate concentrations were generally below the U.S. drinking water standard of 10 mg/l of nitrate as nitrogen. However, higher concentrations and a greater range were evident for the Tangshan region. In the water samples collected from a shallow aquifer in the Tangshan region (over 25% of all samples), nitrate concentrations exceeded the Chinese standard of 20 mg/l, whereas few comparative samples (2.6%) collected in the U.S. exceeded 20 mg/l. In Tangshan, relatively low nitrate, which is indicative of uncontaminated background concentrations, was measured in older water of deeper wells. Recently recharged water was detected in wells drilled as deep as 150 m. Nitrate concentrations above background levels were also measured in water samples from these wells. In addition to nitrate, the agricultural area of the Tangshan region has been affected by elevated total dissolved solids and iron, the latter attributed to widespread application of animal wastes and sewage deposited on the land surface, which lead to oxygen depletion in the subsurface environment and dissolution of iron. The elevated total dissolved solids of the Tangshan study area could not be attributed to any one process.

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.

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.

A study was conducted to evaluate the hydrochemical processes controlling the water quality variations and to determine the water type of groundwater in Rajshahi City, Bangladesh, for drinking purposes. A total of 120 shallow and deep tubewell water samples were collected in pre- and post-monsoon seasons during the year 2008–2009 and analyzed for various physico-chemical parameters. The results of the analyses show that water samples were slightly alkaline to neutral pH. The average concentrations of Pb in all samples for the post-monsoon season were above the WHO's guideline for drinking water. For both seasons, arsenic levels exceeded the drinking water standard in 25% of groundwater samples and lead (Pb) levels exceeded in about 60% samples which contained elevated levels (>0.01 mg/L). The major cationic and anionic orders of dominance were unusual, being Ca2+ > Mg2+ > Na+ > K2 > Fe3+ > Pb2+ > Zn2+ > Cu2+ > As (total) > Cd2+ and HCO3− > Cl−> SO42− > NO3−, respectively. The study reveals that the water type of the groundwater was calcium bicarbonate (Ca-HCO3). Thus overall results suggest that groundwater quality of the study area was not suitable for drinking purposes without treatment especially for Pb and As.

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.

Abstract There are mainly two types of solids in the oil field waters; Suspended Solids (SS) and Total Dissolved Solids (TDS). While it is easy to remove SS from water, removal of TDS requires the application of advance filtration techniques such as reverse osmosis or ultra-filtration. Because these techniques cannot handle high volumes of the oilfield waters with high TDS content, produced waters originated from hydraulic fracturing activities cannot be treated by using these advance technologies. Thus, in this study we concentrated on the pretreatment of these waters. We investigated the feasibility of the Coagulation, Flocculation, and Sedimentation (CFS) process as pretreatment method to reduce mainly SS in Produced Water (PW) samples. We collected samples from 14 different wells in the Permian Basin. First, we characterized the water samples in terms of pH, SS, TDS, Zeta potential (ZP), Turbidity, Organic matter presence and different Ion concentration. We tested varying doses of several organic and inorganic chemicals, and on treated water samples we measured pH, TDS, SS, Turbidity, ZP and Ions. Then, we compared obtained results with the initial PW characterizations to determine the best performing chemicals and their optimal dosage (OD) to remove contaminants effectively. The cation and anion analyses on the initial water samples showed that TDS is mainly caused by the dissolved sodium and chlorine ions. ZP results indicated that SS are mainly negatively charged particles with absolute values around 20 mV on average. Among the tested coagulants, the best SS reduction was achieved through the addition of ferric sulfate, which helped to reduce the SS around 86%. To further lessen SS, we tested several organic flocculants in which the reduction was improved slightly more. We concluded while high TDS in the Permian basin does not implement a substantial risk for the reduction of fracture conductivity, SS is posing a high risk. Our study showed, depending on components of the initial PW, reuse of the pretreated water for fracturing may minimize fracture conductivity damage.
