Seasonal Monitoring using Harmonic Analysis of Water Quality in Lower Yamuna Basin
Journal Title: Universal Journal of Environmental Research and Technology - Year 2014, Vol 4, Issue 1
Abstract
Regular monitoring of water quality helps in identification of nature and extent of pollution and its control. It also helps in prioritisation of pollution control activities, formulation of standards, assessment of adequacy and effectiveness of various pollution control programs. The existing network of water quality monitoring at selected stations in the lower Yamuna basin with periodic variations analysed using harmonic analysis is presented in this paper. Measurement of water quality at selected sites in a basin has to be done in an equally rational manner that puts more emphasis on anthropogenic inputs nowadays. The status of water quality is assessed both inside as well as outside the basin at outlet points of tributaries on main Yamuna river especially from the point of confluence of Chambal till its confluence with Ganga. In order to obtain overall status of water quality, composite index of water quality has been derived using MS-EXCEL based on data from Central Pollution Control Board. It was found that pH and temperature; biological oxygen demand (BOD) and chemical oxygen demand (COD); and faecal and total coliforms (TC and FC) - are important component of water quality monitoring in the region.
