ABSTRACT
Water pollution is a major global problem. It has been suggested that it is the leading worldwide cause of deaths and diseases and that it accounts for the deaths of more than 13,700 people daily in Kanpur U.P India. Nitrate and Nitrite pollution is one of the groundwater's most identified contaminants, an indicator of serious pollution as they are associated with septic waste and agricultural endeavors, leading to numerous health problems for human beings and animals. Fast urban growth, without proper arrangements for waste management, led to serious problems of contamination of groundwater in many urban centers of India. The present study indicates how uncollected and mismanaged waste contaminates the groundwater. A detailed survey of nitrate levels in groundwater was carried out in Kanpur to assess the magnitude of the problem in different areas. Nitrate, which may cause methemoglobinemia or "blue baby" disease, is found much above the drinking water limits prescribed by WHO and the Bureau of Indian Standards. 46% of the samples showed values higher than the prescribed limit of 45 mg/l as per BIS: 10500-2004. Since groundwater is the source of drinking in many parts of the city as the municipal water supply is inadequate due to the growing demand for drinking water, the dependence on groundwater is inevitable. Thus, exposure of the population to high nitrate cannot be ruled out. In this paper different areas of the Kanpur, the region were studied. The main objectives are to find out the health impact of consuming high nitrate groundwater in different parts, especially in an industrial area.
