A Study on Assessment of Pollution of Tunga River and Adjoining Ground Water
Abstract
A Study on Assessment of Pollution of Tunga River and Adjoining Ground Water Tunga River has been one of Karnataka’s most prominent and important river in Shimoga District. Unfortunately, there are a lot of polluted stretches of River Tunga. On the banks of the Tunga River, various urban centers draw fresh water for various activities. The objective of the monitoring studies undertaken for water body is to assess with time the variation in water quality.
Water in nature is the essential fluid from which all life begins. All living things also need water to maintain their lives. It is very useful in domesticity, such as for washing and cleaning. It is the common solvent for paper and water, textile and electroplating in industry.
In addition, electricity generation also requires water. It has numerous uses. It can be easily polluted, though. Pollutants deteriorate the quality of the water and make it unfit for its intended uses. The pollution of rivers and streams with chemical contaminants has become one of the most critical environmental issues of the century.
Water is one of the most common and precious resources on earth without life on earth. Pollution is a serious problem as nearly 70 percent of India’s surface water resources and a growing number of its groundwater reserves have been contaminated.
The quality of water is described by its physical, chemical and microbiological characteristics. As a result, regular monitoring of river water quality not only prevents disease outbreaks and controls water from further deterioration, but also provides a scope for assessing current investments in pollution prevention and control.
Conclusion
The present study concluded that study area river water was moderately polluted with respect to analyzed parameters. While pH, total hardness, chloride and fluoride were found within the permissible limit, the higher BOD and COD values attributed to river water in the present study were not suitable for drinking. It needs to be aware of local villagers in order to protect the precious river and its surroundings
