“…TDS represents the dissolved salts in groundwater and is usually used to determine the suitability of groundwater for drinking purpose (Rajesh et al 2015). TDS in the study area ranges from 248.00 to 2142.00 mg/L with an average of 685.64 mg/L, which indicates that some samples are brackish water that is unsuitable for drinking.…”

“…The Western Development Program (WDP), initiated in 2000 by the central government of China, introduces a number of industries to this area, bringing along serious contamination to groundwater while creating wealth and prosperity to local residents. To change this situation, Chinese government has recently released a series of national plans, guidelines, and laws to combat groundwater pollution: for example, the National Plan of Groundwater Pollution Prevention for the years 2011-2020 (Ministry of Due to the increasing importance of water-quality assessment in water resources management, a number of scholars have performed this important work in various regions by a variety of methods (e.g., Al-Rawabdeh et al 2014;Golekar et al 2013;Rajesh et al 2015;Vetrimurugan et al 2013;Vetrimurugan and Elango 2014). Recently, Rao et al (2013) applied electrical resistivity tomography (ERT) methods in the delineation of groundwater contamination and potential zones in India.…”

Intensive human activities have caused contamination to groundwater quality which consequently affects human health. In this study, an evaluation of groundwater quality was carried out for better understanding of the status of groundwater contamination and potential risks to local residents in an alluvial plain (China) where agricultural and industrial activities are intensive. Comprehensive water quality index was used for drinking water-quality assessment and sodium adsorption ratio, Na%, and residual sodium carbonate were applied for irrigation water-quality assessment. The human health risks caused by intake of the contaminated groundwater through the oral and dermal pathways were also assessed. The assessment results reveal that most of the water samples are generally suitable for irrigation purpose, but over 60 % of them are not fit for drinking, and the total hardness, NO 3 -, NO 2 -, TDS, SO 4 2-, and F -are the main contaminants affecting its suitability for drinking purpose. Residents in the study area are at high health risk, and NO 3 -originating mainly from industrial and agricultural pollution is the greatest contributory cause of the health risks. Furthermore, children in this area are at higher health risk than adults, and oral ingestion is the dominate exposure pathway of health risk. Therefore, urgent and efficient measures must be taken to combat groundwater pollution and reduce health risk in the area.

Engaging students in the experimental design of “green” technology is a challenge in Chemical Engineering undergraduate programs. This concept paper demonstrates an educational methodology to investigate accelerated mineral carbonation, which is a promising technology related to mitigation of climate change by sequestering carbon dioxide (CO2) from industrial sources as stable solid carbonates. An experimental investigation is conceived, whereby students test the effect of two process parameters (CO2 pressure and mixing rate) on the extent of carbonation reaction. The carbonation reaction has been performed using a mineral called wollastonite (CaSiO3). The experimental study and laboratory report cover principles of reaction kinetics and mass transfer, while illustrating the steps to develop and investigate a green process technology. The results from the experimental investigation, which is carried out by multiple teams of students, are then pooled and used to guide a subsequent design project. Students would conceive a flowsheet, size equipment, and estimate the energy demand and net CO2 sequestration efficiency of a full-scale implementation of the mineral carbonation technology. This educational investigation aims to help undergraduate students to acquire deeper experiential learning and greater awareness of future green technologies by applying fundamental engineering principles into an engaging experimental and design exercise.

“…Bearing this in mind, proper identification of soil characteristics is also vital as it influences the quality of surface and groundwater, especially in arid and semiarid regions (Engelman and Leroy 1993;Lal and Stewart 1994). Several investigators have applied the combination of electrical resistivity method with water chemistry to decipher the aquifer parameters and quality of water (Mondal et al 2013;Rajesh et al 2015;Batayneh and Al-Taani 2016; and references therein). Few researchers have attempted to evaluate the groundwater potential zones, its contamination and fertility prospects of soils using PSA and metal contents in soils (Inakwu et al 2003;Skordas and Kelepertsis 2005;Deshmukh and Aher 2014;Machender et al 2014).…”

, using electrical resistivity technique. The study was also aimed at alleviating the drinking water scarcity in these regions. A total of 118 vertical electrical sounding sites were occupied using Schlumberger electrode configuration and the data analysis revealed two to five layered curve types. The modelled layer resistivity and layer thickness at every station were used to calculate the Dar-Zarrouk parameters (i.e., longitudinal conductance S and transverse resistance T). The S values showed that 67% of the area had a poor aquifer protection, whereas 16% had moderate protective capacity and 13% had weak aquifer protective capacity rating. Only 4% of the study area depicted a good protective capacity rating. This indicates that the study area has a rather poor aquifer protective capacity rating, and thereby more prone to infiltrating contaminants. The regions with good-to-moderate protective capacity are envisaged to be potential groundwater zones. The large variation in electrical anisotropy λ ranging from 1 to 2.8 in the study area suggests the anisotropic disposition of the aquifers in basaltic region. The intersection points of several lineaments in the study area are probable to be the most favourable zone for groundwater recharge. This is corroborated by the lineament density of the area, wherein high lineament density reflects high probability of groundwater infiltration. Moreover, the rainfall distribution suggests that the central and eastern parts of the study area receive maximum precipitation, which also coincides with the zones of high lineament density. Particle size analysis was determined from 92 soil samples in the study area and correlated with the longitudinal conductance in order to identify the sub-surface conditions and the aquifer vulnerability. Significant positive correlation was observed between the longitudinal conductance and percentage of clay fraction in the study area. These results could be relied upon for making preliminary estimates of protection from pollution for a sustainable groundwater development and management in future.
