Study on Physico-Chemical and Microbial Parameters of Water Supply from Hisar city, Haryana

摘要

The present research work deals with the study of some of the important physico-chemical and microbial parameters of 24 samples collected from water supply of Hisar city, for a period of four months june-september (2015) at weekly intervals. This study showed the result of four water works namely as Mahavir Colony Water Works, Kaimiri Road Water Works No. 2, Satroad water works and PTU Water Works and twenty wards of Hisar city. Twenty-four samples are subjected to physico- chemical analysis like pH, temperature, total hardness, conductivity, total alkalinity, turbidity and free residual chlorine. The most probable number (MPN) test was done to detect the total coliform and fecal coliform in water samples. The Hisar is major city of Haryana and the main source for water supply are Balsamend branch, Hisar major and Rana distributor canal interconnected to four water works. These water works supplied in twenty wards under Public Health Engineering Department, Haryana. The parameters ph, temperature, conductivity, total hardness, total alkalinity & chloride content were found within the BIS standard limits. The turbidity was found highest in the Mahavir colony water works and ward number (1) 3.3 and 11 NTU respectively. The free residual chlorine were deducted in three water works and ward number (17). The total coliform and fecal coliform were deducted only in PTU water works 300 and 50 MPN/100ml respectively. The total coliform and fecal coliform were deducted highest in ward number (3) 1600 MPN/100ml respectively.
