Groundwater quality is widely compromised by anthropogenic impact. This becomes evident by the presence of numerous anthropogenic organic and inorganic contaminants in groundwater. Contaminants are of widespread origin. They enter the groundwater associated to different processes such as sewer failure, agricultural activities or contaminated industrial sites. Understanding the input mechanism, transport, attenuation and degradation processes in short and long term is crucial for sustainable groundwater development. Although unwanted, contaminants even in smallest quantities might provide...
