TAILIEUCHUNG - Water Pollution: Impact of Pollutants and New Promising Techniques in Purification Process

Of late, the coastal ecosystems are highly degraded due to high population and industrial growth (Glasby & Roonwal, 1995; UNEP, 1997). Due to various pollutions including pesticide poisoning (Sen Gupta et al., 1990), over exploitation of water resources by power plant industries and the municipal uses and encroachment for urban developments force the fishing community to the brink of disappearance. When those natural resources are imperilled, so too are the livelihoods of the many people who live and work there. The environmental abuse and the negligence of the governing body make the matter worse (Sreenivasan & Franklin, 1975) | Kamla-Raj 2012 J Hum Ecol 37 2 103-109 2012 Water Pollution Impact of Pollutants and New Promising Techniques in Purification Process Ramandeep Singh Gambhir1 Vinod Kapoor2 Ashutosh Nirola3 Raman Sohi4 and Vikram Bansal4 Department of Public Health Dentistry 2 Department of Oral and Maxillofacial Surgery Gian Sagar Dental College and Hospital Rajpura India 3Department of Periodontology Laxmi Bai Dental College and Research Centre Patiala India 4Department of Public Health Dentistry .

Pure Water ABSTRACT Water is a critical resource in the lives of people who both benefit from its use and who are harmed by its misuse and unpredictability flooding droughts salinity acidity and degraded quality . Water is a finite and vulnerable resource. Consequently consumption of polluted water puts lives and livelihoods at risk because water has no substitute. There are many ways in which water intended for human consumption can get polluted. These include wastes from industries like mining and construction food processing radioactive wastes from power generating industries domestic and agricultural wastes and by various microbiological agents. Nowadays water is being purified by various methods but research is being conducted to look for more reliable and cheaper methods that can purify water at an affordable cost. Various techniques have been developed like utilizing rechargeable polymer beads seeds of Moringa Oleifera tree aerobic granular sludge technology resin based treatment and two-pronged water treatment techno logy. INTRODUCTION Water is that chemical substance which is essential for every living organism to survive on this planet. Water is needed by every cell of the organism s body to perform normal function. Water covers 71 of the Earth s surface mostly in oceans and other large water bodies with of water below ground in aquifers and .
