Load of Industrial & Domestic Waste in the Ground Water

Groundwater contamination is a global problem that has a significant impact on human health and ecological services. Studies reported in this special issue focus on contaminants in groundwater of geogenic and anthropogenic origin distributed over a wide geographic range, with contributions from researchers studying groundwater contamination in India, China, Pakistan, Turkey, Ethiopia, and Nigeria. Thus, this special issue reports on the latest research conducted in the eastern hemisphere on the sources and scale of groundwater contamination and the consequences for human health and the environment, as well as technologies for removing selected contaminants from groundwater. In order to evaluate the effects of seeping septic effluents on the quality of groundwater in a watershed, a number of contaminants such as nitrate, phosphorus, chloride, lead, copper, iron, chromium and manganese, were studied. To determine the extent of contamination, a network of observation wells was established in the drainage area of the septic systems. Groundwater samples from the observation wells were collected in the spring, summer and fall. The samples were extracted for the determination of various contaminants by standard methods. Landfills are the most widely used method for municipal solid waste (MSW) disposal method in Kanpur. However, these facilities have caused serious groundwater contamination due to the leakage of leachate. Dumpsite is a widespread land meant or designed for deposition of waste and unwanted materials from household, institutions, industries or the environment and is generally open or covered with soil layer with or without liner at the bottom. Dump/landfill is a major source of contamination of groundwater. This study is therefore designed to review studies on the impact of groundwater contamination due to dumpsites using geophysical and physiochemical methods
