Assessment of Water Quality of Mahanadi and It's Tributary Katha Jodi River, Cuttack District, Odisha

Abstract

For all living things, water is one of the most important sources. Despite being a renewable resource, clean water scarcity is a major problem in many regions of the world. We require water for a variety of things, including food production, personal hygiene, electrical generation, fire control, and most importantly, survival. Nine sampling stations were chosen at various locations along the Mahanadi and its tributary, the Katha Jodi River, in the Cuttack area (S1-S9). To collect a tiny amount of water from the water source for water analysis and to look at the physico-chemical components that are present in the water, sampling is done. Our study sites' dissolved oxygen concentrations range from 3.9 to 5.8 mg/lit, and the water samples from all of the sites are only mildly alkaline. All study sites have alkalinities below 150 mg/lit, ranging from 129 mg/lit to 162 mg/lit. All of the study sites' water conductivities are within the typical range of river water, or 200 to 1000 mhos/cm. All of the study locations, with the exception of our study sites 1 and 2, have high nitrate levels of greater than 100 mg/lit. Our study sites had phosphate concentrations between 0.8 and 2.0 mg/lit, and a river shouldn't have more phosphates than 0.1 mg/L. Over these limits, phosphorus can be quite hazardous.
