“…Absorption and liberation of the heat accumulated on the panels disturb the thermal profile and can harm the flora and fauna of the location. Water cooling consumes considerable water taken from nearby reservoirs or from underground [41]. Usually, the treatment of water becomes necessary in order to protect panels from chemical effects such as corrosion and deposits.…”

Photovoltaic panel performance in terms of its efficiency and durability is severely affected by operating temperature when the temperature is much higher than the nominal operating cell temperature in hot climates. Different cooling methods have been reported over several decades, but photovoltaic panel manufacturers or users are yet to adopt a popular method of panel cooling. This is the main concern of the present work. Potential cooling solutions differ in terms of their criteria for performance evaluation, which are efficiency enhancement, costs, reliability, environmental aspects and ergonomics. Hence, there is a need to identify the optimum cooling method. Eight different cooling methods were identified, and the analysis was made with the multi-criteria analysis tool on the different possible attributes. Two different climate zones with different weight schemes are considered for the evaluation process, and the best to the worst cooling solutions have been identified. Five different scenarios depending on the importance given to each evaluation criterion are analyzed. The best cooling method to the worst cooling method has been arranged under each scenario. When the efficiency of operation was given maximum weight, aluminum fin cooling proved to be the best panel cooling method. When the emission reduction criterion was given maximum weight, thermosiphon cooling was the best cooling option. A comparison of the results indicates that thermosiphon works out to be the best option. The second-best method was found to be forced convection cooling when equal weights were applied and thermosiphon cooling when a 40% weight on efficiency enhancement criteria was applied, which is a more practical weight distribution. Phase change cooling and forced convection cooling had the poorest performance among the different cooling methods for all the weighing scenarios.

“…Water is an important part of everyday life in the animal and human. More than 70% of the earth's surface is water, yet we can use only 1% of water due to the salinity (97% of the total water) of nature (Jha et al, 2007;Das et al, 2019).According to the National Oceanic and Atmospheric Administration (NOAA), about 30% of liquid freshwater sources are ground water that accumulates in sub-surface geological formations of Earth's crust (Fitts, 2002;Arulbalaji et al, 2019).As groundwater is an important natural resource for domestic, agricultural and industrial use, its demand is increasing day by day due to population growth, urbanization, improved irrigation systems and industrial expansion etc (Jha et al, 2007;Manap et al, 2012;Celik, 2019;Andualem and Demeke, 2019;Javaid et al, 2020).Therefore, groundwater is a primary problem in monsoonal countries like India due to hasty depletion of water (Maity and Mandal, 2019; Kumar et al, 2020).Groundwater extraction has also become an essential element of water management and planning, especially in rural areas (Das and Pardeshi, 2018;Mallick et al, 2019).…”

“…The potential of groundwater anywhere is the result of reciprocity principles between hydrology, geology, biological factors, etc (Das, 2019).The natural recharge, accumulation, potentiality and ow of groundwater in an area is driven by a variety of geo-environmental factors such as lithology/geology, geomorphology, lineament features or density, soil, slope, drainage, rainfall, land use/land cover (LULC) (Al-Adamat et al, 2003;Kumaret al, 2016;Shekhar et al, 2017;Sa Costa, 2019;Javaid et al, 2020).The natural recharge of groundwater is in uenced by the interrelationship between these factors.…”

In the present era, due to immense demand and excessive exploitation, ground water is thriving depletion and stress. Sustainable groundwater management and development is essential for the green revolution and industrialization through scientific and modern quantitative techniques. The integrated geographical information system (GIS) based analytical hierarchy process (AHP) of multi-criteria decision analysis (MCDA) technique is adopted to establish the importance of ground water influencing factors. In the present study eight groundwater influencing parameters viz. geology/lithology, geomorphology, lineament density, drainage density, slope, soil permeability, land use/land cover and rainfall have been used to assess ground water potential zone (GWPZ).An appropriate weight was assigned for each factor/parameter based on 9 point scale of Saaty and the weights were normalized by AHP and eigenvector method with standard value (0.000000085) of continuity ratio (CR). The Noamundi area of Jharkhand has been selected as a projected area for the study. In accordance with MCDA's GIS based AHP model, five GWPZs have been categorized in the projected area comprising very good (2.07%), good (15.15%), moderate (41.18%), poor (39.37%) and very poor (2.24%) GWPZ. Finally, the results have been validated with randomly scattered existing groundwater table and yield data (open dug well, Bore well, rig well and tube well).

“…However, it is threatened by over-exploitation and pollution (Carrard et al, 2019). Groundwater quality is influenced by geogenic and anthropogenic processes (Javaid et al, 2020). It is naturally found in association with geologic minerals containing dissolved salts (Chacha et al, 2018).…”

Groundwater from shallow hand-dug wells at an abandoned gold mine tailings dam was characterised for selected physicochemical parameters during dry and wet seasons of 2018 and 2019. Health risk exposure of the local population (adults and children) through ingestion and dermal exposure was assessed. Groundwater quality parameters were lower than international drinking water quality guidelines (p < 0.05). The parameters were significantly influenced by season of the year (As, Cl−, SO42−), nature (As, Cd, Cl−, Fe, NO3−, SO42−), depth (Cd, Cl−, Fe, Ni, SO42−) and direction of the well (Cu, Cl−, Fe, NO3−, Pb, SO42−) (p < 0.05) relative to the tailings dam. Groundwater did not pose non-carcinogenic risk due to studied trace elements. However, arsenic had the potential to cause medium to high cancer risk to the local population. We propose re-vegetation of the tailings dam, diversion of surface tailings drainage to a containment pond and the provision of continuous piped water supplies.
