Landfill leachate a new threat to water quality: a case study from the Temperate Himalayas

Abstract

Land lls are regarded most cost effective and accomplishable operation for managing waste in numerous parts of the world. Inspite of many merits, it gives rise to remarkable menace to different domains of the environment owing to the existence of noxious inanimate and animate components in the leachate and imperfectly evolved solid refuse handling techniques. Water is indispensable for bolstering existence, growth, and the environment and is one of the fundamental indicator of scal expansion and communal opulence of a country. Percolation of noxious substances from unscienti c dumpsites is among the main environmental consequences of these land lls in majority of the progressing countries like India. Leachate serves as a prominent point source of contamination in many environmental media like soil, ground water and surface water around the world. So the prime issues humans are experiencing are associated with water quality. Thus the investigation was accomplished to investigate the impact of leachate from Achan land ll on surface water quality in Temperate Himalayas. Monitoring was done during all the four seasons viz, spring, summer, autumn and winter. Leachate out ow site was found to have highest mean value of pH (8.4), EC (4.50), total Nitrogen (3.55),
