Abstract
The Kanhan River originates from the high lands of Chindawara District and flows in south east direction for about 160 kms before it enters the state of Maharashtra near Raiwari village in Saoner Taluka of Nagpur District. Nagpur city is presently getting water for from two major sources namely Kanhan River (Head work located near village Juni Kamptee) &Pench Dam (through Right Bank Canal with Lifting Point at Mahadula at 48.5 Km of canal). Samples were collected from seven major locations along the stretch of river. The samples were subjected to physicochemical analysis and performed during summer, rainy and winter seasons. The physicochemical parameters of the water samples includes pH, temperature, turbidity, conductivity (EC), suspended solids (SS), total dissolved solids (TDS), total solids (TS), dissolved oxygen (DO) and biological oxygen demand (BOD). The water quality index (WQI) is used to evaluate the quality of the river water for drinking in rainy, winter and summer season.The study was carried out to examine the change in the quality of the river water due to addition of human waste discharge, industrial waste discharge into river body and the seasonal variation in the physicochemical properties of the river.
Highlights
Water is the prime requirement for the existence of life and it has been man’s endeavor for the time immemorial to utilize the available resources
The water temperature showed an upward trend from winter season to summer season followed by a downward trend from rainy season onwards
The waste water from the residing area resulting from the domestic use is discharged into the water body
Summary
Water is the prime requirement for the existence of life and it has been man’s endeavor for the time immemorial to utilize the available resources. Water is a ubiquitous chemical substance that is composed of hydrogen and oxygen and is vital for all known forms of life. Water refers only to its liquid from or state, but the substance has a solid state, ice, and a gaseous state, water vapor or stream. Watercovers 71 % of the earth’s surface. On earth, it is found mostly in oceans and other large water bodies, with 1.6 % of water below ground in aquifers and 0.001 % in the air as vapor, clouds (formed of solid and liquid water particles suspended in air), and precipitation. A very small amount of the earth’s water is contained within biological bodies and manufactured products
