“…Thus, a safe limit of 50 mg L -1 NO 3 in drinking water has been established by the World Health Organization (WHO 2011). Typically, in arid countries such as Saudi Arabia, where there are limited water resources, high concentrations of NO 3 ([180 mg L -1 ) emanating from nitrogen fertilizers and sewage seepage have restricted groundwater use for drinking purposes (Loni et al 2014;Metwaly et al 2014). Furthermore, high NO 3 content ([200 mg L -1 ) in industrial wastewater (Aly et al 2014) poses a treatment challenge.…”

Biochar has emerged as a universal sorbent for the removal of contaminants from water and soil. However, its efficiency is lower than that of commercially available sorbents. Engineering biochar by chemical modification may improve its sorption efficiency. In this study, conocarpus green waste was chemically modified with magnesium and iron oxides and then subjected to thermal pyrolysis to produce biochar. These chemically modified biochars were tested for NO3 removal efficiency from aqueous solutions in batch sorption isothermal and kinetic experiments. The results revealed that MgO-biochar outperformed other biochars with a maximum NO3 sorption capacity of 45.36 mmol kg(-1) predicted by the Langmuir sorption model. The kinetics data were well described by the Type 1 pseudo-second-order model, indicating chemisorption as the dominating mechanism of NO3 sorption onto biochars. Greater efficiency of MgO-biochar was related to its high specific surface area (391.8 m(2) g(-1)) and formation of strong ionic complexes with NO3. At an initial pH of 2, more than 89 % NO3 removal efficiency was observed for all of the biochars. We conclude that chemical modification can alter the surface chemistry of biochar, thereby leading to enhanced sorption capacity compared with simple biochar.

“…The removal of Na from the groundwater system may be attributed to the reverse ion exchange processes (Rajmohan & Elango, 2004). But Loni et al (2014) is of the opinion that Na + ions should show relative abundance over Cl − ion in the presence of silicate weathering, which is not the case in the present case in certain groundwater samples. The positive CAI values (viz., mean CAI-1 = 0.34 and mean CAI-2 = 0.29) in 88.24% of the groundwater samples indicated that the concentration of calcium and magnesium in the study area is due to rock weathering, wherein there is an exchange of Na and K from the water with Mg and Ca of the rocks in the study area (Figure 8).…”

Groundwater samples from thirty four bore wells used for drinking and irrigation in parts of Hoskote and Malur taluks, Karnataka State (India), were collected and geochemically analysed during December 2014. The hydrochemical characteristics was dominated by Ca(58.82%) and Ca 2+ -Mg 2+ -HCO3 -(38.24%), with alkaline earth (Ca+Mg) exceeding alkalies (Na+K) and strong acidic anions dominating weak acidic anions. Weathering of rock-forming minerals regulated chemistry of the groundwater in the study area as indicated by Gibbs plot. The groundwater chemistry in the study area is influenced by silicate dissolution of host rock with contribution from weathering of carbonate rocks while positive CAI values indicated exchange of Na and K from the water with Mg and Ca of the rocks in the study area. The Ca 2+/ Mg 2+ molar ratio plot further supported the fact that dissolution of calcite with effect of silicate minerals contributes calcium and magnesium to 97.06% of the groundwater. SAR, percent sodium, WQI and permeability index values demonstrated the suitability of a majority of the samples for irrigation.

“…Post-Qusaiba aquifers, such as the Qasr aquifer of the Jauf Formation, are described in Al-Aswad & Al-Bassam (1997), Al-Bassam et al (2000), Al-Mahmoud (2015), and elsewhere. The Triassic Jilh aquifer system, recently used as a water source for slickwater hydraulic fracturing projects in the Northern Exploration Area, is one of the secondary, minor groundwater systems of Saudi Arabia consisting sandstone and shale (Loni et al 2014) with increasing limestone content and carbonate facies toward the northeast (Carrigan 1994). Saudi Aramco is recently evaluating alternative water sources (i.e.…”

Provenance studies of produced water are essential to trace flow dynamics and reservoir compartmentalization in petroleum systems and to quantify fluid recovery rates from unconventional fracturing. Produced water from a hydraulically fractured well in the Qusaiba Hot Shale in the Northern Exploration Area, Saudi Arabia, was daily monitored and analyzed for water chemistry, and environmental (δ2H, δ13C, δ18OH2O, δ18OSO4, δ34SSO4, δ37Cl, 87Sr/86Sr) and cosmogenic isotopes (3H, 14C, 36Cl), to differentiate from reference fluids of supply water, fracturing fluids, and formation water from adjacent Paleozoic units. Initially, recovered water is composed of fracturing fluids and subsequently replaced by a homogeneous cut of pristine formation water. Formation water is composed of dominant meteoric water (approximately 84 vol%) and minor fossil evaporated seawater. The young 14C‐apparent age between 6000 and 6700 years BP and depleted δ18O/δ2H values for the meteoric component confirm the infiltration of surface water into the Qusaiba Hot Shale interval or adjacent units during the Early Holocene Pluvial Period under cooler and wetter climatic conditions than present, which suggest the presence of a very recent, dynamic hydraulic flow system. 36Cl/Cl ratios between 102 × 10−15 and 31 × 10−15 are ambiguous and can be attributed to atmospheric recharge close to the coast, mixing of 36Cl‐enriched Quaternary meteoric recharge with 36Cl‐depleted fossil seawater, and/or hypogene production by U‐Th‐enriched host rock. Produced waters from Qusaiba Hot Shale are within the compositional range of Na‐Cl‐type formation water from Paleozoic reservoir units in northern Saudi Arabia with salinities from 30 000 to 130 000 mg l−1. As a novel technological approach for exploration wells in Northern Saudi Arabia, multi‐isotopic methods were successfully implemented to quantify flowback volumes from hydraulic fracturing, and to fingerprint pristine formation water or pore water in Paleozoic systems on their provenance, residence time, migration pathways, and secondary alteration processes.
