Analyses of water quality using different physico-chemical parameters: A study of Saryu river

Abstract

Saryu river is considered the holy river in Ayodhya, Uttar Pradesh, India. But, due to human anthropogenic activities, water quality is deteriorating. The present study aimed to analyse physicochemical parameters with seasonal variations, and bacterial population to monitor river water quality using standard methods. Most of the physicochemical parameters (mainly pH, DO, BOD and TDS) were found with in permissible limits recommended by regulatory authorities. Other parametrs like chemical oxygen demand (COD) and total suspended solids (TSS) values were slightly excess of the permissible standards. Microbial analyses were carried out, that showed the presence of bacterial and fungal populations. Bacterial count was higher in rainy season followed by summer and winter seasons. The findings of this study can be useful to monitor the water quality in different seasons, for drinking and irrigation purposes.
