2 Jun 2017 Abstract: The present study focused on the groundwater contamination due to fly ash disposal of coal-fired thermal power plant into a non liner ash pond. Six vil- lages were selected as study site around ash pond of Parichha thermal power plant,. Jhansi. Groundwater samples were collected on seasonal 1 Dec 2014 Underground coal gasification (UCG) generates potential groundwater pollution because it changes local hydrogeological parameters. power of water increases, and density and viscosity of water decreases.

In areas where population density is high and human use of the land is intensive, ground water is espe- cially vulnerable. Virtually any activity whereby chemicals or wastes may be released to the envi- ronment, either intentionally or accidentally, has. below, each of these pathways and the pollutants associated with them is described. Coal Mining. Coal mining harms land, surface waters, groundwater . Pollution. Air emissions from power plants are subject to require- ments of the Clean Air Act (CAA). Coal contains many trace elements that are released during coal based thermal power plants. The present fly ash generation rate is about 131.09 x 106 tonnes per annum and utilization rate is 73.13 x 106 tonnes per annum . The unmanaged disposal of such huge quantity of fly ash is major problem, probably the leaching of pollutants into surface and ground water. Groundwater Air. Operating power plants that burn coal, oil, or natural gas emit air pollutants into the atmosphere requiring the plant be fitted with pollution control equipment to reduce emissions. Many of these power plant air pollutants have been identified and are regulated by federal and state environmental regulatory agencies.
