“…Enrichment Pb indicating that the sediments were polluted [29] and allegedly originated consequently may cause significant ecological effect on the sediment surface (Desert et al, 2017). Enrichment lead (Pb) on sediment indicates the anthropogenic influence due to deposition and absorption by dredging on tailing process and disposal gas and oil on heavy equipment bauxite mining [30]. The enrichment of Zn appear to be present in the bottom level in amounts, which is explained by the high adsorption capacity of ground because Zn had correlation mainly in smaller grain size [31].…”

Bauxite production and exploration give negative impact environmental modification and increasing concern pollution of heavy metals. One of an alternative to reduce the negative impact of bauxite post-mining production is by re-utilizing the abandoned bauxite land and necessary exploratory study to obtain the current environmental conditions primarily related to heavy metals in bauxite mining area. Soil and water quality samples from 5 (five) sites based on post-mining activities were used to determine concentration heavy metals of As, Cd, Pb, Zn, Cr, Cu from different soil level. They were also collected for grain size analysis including those of sand and mud percentages along with the mean, and sorting analysis. The mean grain size post-mining bauxite ranged between very fine sand to medium sand and had heterogeneous texture. The coarse grain size percentage increased towards the bottom of the soil. Total heavy metal contents for post-mining bauxite soils are 0,081 ppm, 0,245 to 0,471 ppm and 0,007 ppm for As, Pb and Cd respectively. Heavy metals for Cd, uniformly at every depth from soil level. On the other hand, Pb showed significance pattern, it was indicated every depth from soil level, the concentration of Pb was different.

“…Contamination might be due to natural causes, for example arsenic (As) or nitrate (NO3 -)-containing rocks (Menció et al, 2016;Tabelin et al, 2018) or more frequently by anthropic activities. Hence, a large variety of contaminants can be found in groundwater: aromatic compounds and chlorinated hydrocarbons (Logeshwaran et al, 2018), inorganic metallic compounds (Galitskaya et al, 2017;Luu et al, 2009), and nutrients (Chen et al, 2016). Recently, pharmaceutically active compounds (PhACs) and contaminants of emerging concern (CECs) have also been identified in groundwater as solutes (Lopez et al, 2015).…”

Groundwater contamination is an ever-growing environmental issue, that has attracted much and undiminished attention for the past half century. Groundwater contamination originates from anthropogenic (e.g. hydrocarbons), natural compounds (e.g. nitrate and arsenic), or both; to tackle these contaminants different technologies have been tested during the years. Recently, bioelectrochemical systems (BESs) have emerged as a potential treatment for groundwater contamination, with in situ applications reported, that showed promising results. Nitrate and hydrocarbons (toluene, phenanthrene, benzene, BTEX and light PAHs) have been successfully removed, due to the interaction of microbial metabolism with poised electrodes, other than physical migration due to the electric field generated in BES. The selection of proper BESs relies on several factors and problems such as complexity of the groundwater, scale-up and energy requirements that need to be taken into account. Modelling efforts could help predict case scenarios and choose an ideal design and approach to solve these issues. In this review, we critically analyze in situ BES applications for groundwater remediation, focusing in particular on the different setups proposed, and we identify and discuss the existing research gaps in the field.

“…There are several techniques are available to manage groundwater resources but among them groundwater modeling is the best choice and the model is a simplified version of the real system (Adane, 2014). Several regional groundwater modeling studies have been accomplished in different part of world (Moeck et al, 2017;Gebreyohannes et al, 2017;Asoka et al, 2017;Galitskaya et al, 2017;Kambale et al, 2017;Abdullah and Morteza, 2017;Durand et al, 2017;Carretero et al, 2013;Moon et al, 2010;Abu-el-Shar and Hatamleh, 2007). They used different models for groundwater management and emphasized that the model techniques could be helpful for management of the groundwater resources (Kori et al, 2013).…”

The application of groundwater resources in Punjab, Pakistan to meet the crop water requirements is increasing rapidly due to constrained surface water supplies. However, the abundant abstraction of groundwater has created serious negative concerns in terms of lowering water table. Thus the sustainability of regional groundwater resources depends upon its proficient management through groundwater modeling technique. Therefore, a research was accomplished to quantify the groundwater pumping and to identify the groundwater depletion areas using MODFLOW model. Three pumping scenarios were developed up to year 2030: such as Scenario-I (Maintaining the current pumping rate for the study period); Scenario-II (Increase in pumping rate according to the historical trend); and Scenario-III (Adjusted canal water supplies and groundwater patterns). The results of Scenario-I indicated that the groundwater level would decline up to 14m for the study period. Scenario-II results showed maximum decline of groundwater level, which would be 18m up to year 2030. The adjusted canal and groundwater supplies among upper and middle part of the study area in Scenario-III, which will recover the groundwater by 2-3m in the middle part of the study area, gave a good management strategy. So, in lower and middle part of study area, groundwater should be artificially recharged and more canal should be supplied water to avoid depletion.
