“…Connate water, seawater, and salt domes have high level of sodium. 33 The presence of sodium ions in irrigation water or soil can impair soil permeability to water. This is an additional effect of sodium that has direct impact on some plants which may be toxic for them.…”

Background: Qanat is a valuable source of groundwater, the maintenance of which requires quantitative and qualitative monitoring. Since the qanat water is currently used in some parts of Iran for drinking and agricultural purposes, its quality management is of great importance. This study aimed to evaluate the water quality of the qanat in the eastern areas of Tehran. Methods: Water sampling was performed in eight qanats in the east of Tehran in triplicate (mother well and one of the access shafts and outlet) during the summer of 2020. The measured parameters were pH, total dissolved solids (TDS), electrical conductivity (EC), CO3 2-, HCO3 - , Na2+, Ca2+, Mg2+, K+, Cl- , NO3 , SO4 2-, total hardness (TH) and total alkalinity (TA). The quality was assessed according to the standards introduced by the World Health Organization (WHO) and Food and Agriculture Organization. Groundwater quality index (GWQI) was used to classify the samples. Results: The lowest (56.05) and the highest (2058.58) GWQI scores corresponded to qanats 5 (Elimon) and 8 (Aminabad) with good and very poor quality, respectively. There was a decrease in the water quality of qanats 8 (Aminabad), 7 (Sulaymaniyah), 6 (Mehdiabad) and 2 (Majidieh), respectively. Conclusion: The quality of the qanats were in the range of good to very poor. The reasons for difference in water quality could be due to the direction of anthropological pollutants and geological structures. To control the water quality of the qanats in the east of Tehran, the quality monitoring network is recommended to be designed for various pollutants and optimized for long term.

“…Recharge, as one of the factors controlling the situation and fluctuation of groundwater, is an important parameter that needs to be assessed more fully. Recharge, occurring in small and large scales, spatially and temporally, is influenced by several factors, such as meteorology, soil characteristics, geology, surface cover, slope, and depth of the groundwater level [3][4][5]. Groundwater recharge estimation from precipitation is an integral part of hydrology and hydrogeology [6].…”

Estimation and forecast of groundwater recharge and capacities of aquifers are essential issues in water resource investigation. In the current research, groundwater recharge and the recharge coefficient were determined through a case study using empirical methods applicable to the tropical zones. The related climatological data between January 1983 and December 2014 were collected from Ogun-Oshun River Basin Development Authority (OORBDA), Ogun State, Nigeria. Using empirical formulae. The results showed that groundwater recharge was 194.7 mm per year, evapotranspiration was 1296.2 mm per year, and the recharge coefficient was 20.2% for the study area. The result also showed that about 11% of rainfall infiltrated the aquifer, 73% was lost to evapotranspiration, and 16% ended up as run-off. Correlation between climatic parameters and groundwater recharge showed the highest correlation between recharge and rainfall. Temperature, humidity, solar radiation and evapotranspiraton were obtained at the 0.01 significance level; the results of linear regressions proved that precipitation has a significant effect (with R 2 = 0.983) on estimated recharge.

Kocurek, Dianna S. (Tischler/Kocurek); Woodside, Gayle (IBM Corp.). The treatment of a particular hazardous waste often involves the integration of a number of unit processes to develop a comprehensive treatment system. This article gives a brief overview of the most common unit processes used for the treatment of hazardous wastes and discusses, as appropriate, how these unit processes are typically combined. Unit processes in this article are divided into three general categories: physical–chemical, biological, and thermal processes. Soil and ground water treatment technologies are presented as a fourth section and include only those technologies that are unique to these media or that are innovative or emerging technologies used most frequently with these media. Physical–chemical processes include air stripping, carbon adsorption, chemical oxidation, dissolved air flotation, distillation, evaporation, ion exchange, membrane filtration, neutralization, oil–water separation, oxidation and reduction, precipitation, sedimentation–clarification, solvent extraction, stabilization–solidification, steam stripping, supercritical fluid extraction, supercritical water oxidation, and wet air oxidation. Biological treatment focuses on the biodegradability of different compounds and the most widely used technology for organic wastewaters, activated sludge. Thermal processes include catalytic oxidation, fluidized beds, liquid injection, multiple hearth furnaces, rotary kilns, and thermal desorption. Soil and ground water treatment technologies include bioremediation ( in situ and ex situ ), electrokinetics, in situ air stripping, pump and treat, soil flushing, soil leaching, soil vapor extraction, soil washing, and vitrification.
