Water Quality Analysis Of Ground Water Sources In Nalbari District, Assam

Abstract

The Nalbari District is situated in between 26^oN and 27^o N latitude and 91^o E and 97^oE longitude. The north and west side of the district is bounded by Baksa and Barpeta district Barpeta respectively. The southern and eastern side of the district is bounded by Kamrup district.  Nalbari district with a geographical area of 1009 sq. km., a thick populated district of Assam. The district area forms a part of great Brahmaputra valley. In 2011 census Nalbari had population of 771639 of which male & female were 396006 and 375633 respectively. There was change of 11.99 percent in the population compared to population as per 2001. The District's population expansion has rendered the water supply plans run by the Municipal Board and PHE Department insufficient.  As a result, the majority of the District's population is forced to use groundwater sources including hand tube wells, tara hand pumps, singur hand pumps, and others.  For these water sources, a number of water quality parameters have been measured using standard techniques, including water temperature, pH, arsenic, iron, total hardness, DO, fluoride, BOD, total coliform, and TDS. These properties have been discovered to vary with time and location, and the differences have been explained.  To determine the level of contamination in these water bodies, statistical techniques have been used to compare the results with the water quality criteria.  In the Nalbari District, ten sampling stations in all were considered for the pre-monsoon, monsoon, and post-monsoon seasons.
