Bank filtration (BF) has emerged as an economical and sustainable water pre-treatment technology for drinking water supply. In this method, subsurface water of a water body moves into the well by seepage. BF wells adjacent to a river or lake pump the stored groundwater abstracted from the surface through aquifers. Chemical and biological contaminants such as turbidity, microbes, dissolved chemicals and natural organics are removed by the channel of aquifers present in the area. The whole process follows a series of physical, chemical and biological processes with some redox reactions. This study highlights the role of BF method in regulating water quality and quantity improvement. Besides, attempts have been made to discuss the mechanism, significance and the development of BF technology in the hilly state of Uttarakhand. Water quality status of Srinagar and Satpuli river BF sites of Uttarakhand are also described and compared with the Bureau of Indian Standards guidelines.Keywords

Energy use in the rice–wheat crop production system is a major contributor to global greenhouse gas (GHG) emissions. Understanding input-wise energy flows in the production system is vital to optimize input–output and estimating GHG emissions and global warming potential. Doon Valley, India, has energy-intensive agriculture practices and a survey-based assessment was undertaken in this area covering 63 farms. According to the present study, rice and wheat production requires 63,825 and 50,799 MJ ha–1 of total energy input respectively. The main contributors were electricity, fertilizers and diesel for both crops; however, irrigation water was also a significant contributor in the case of rice. The yield per unit of energy use was relatively low which warrants better crop management practices to reduce the environmental footprint of the rice–wheat cropping system.Full Text
