Abstract

Deteriorating water quality is becoming a major problem nationwide making it unlikely to meet the demand for fresh water for its growing population unless drastic measures are adopted. The river considered in this study is the Arkavathi an important mountain river in Karnataka originating at Nandi Hills of Chikkaballapur District. The river is used by the Bangalore Water Supply and Sewerage Board to provide 135 million litres of drinking water per day to the city of Bengaluru, or about 20% of all the city's water, it aims to determine the polluting sources responsible for the poor water quality of the Arkavathi River and to suggest a scientific water remediation plan to rectify the same. Due to rapid urban-industrialization and domestic needs of the people which are responsible for polluting Arkavathi river by direct disposal of untreated effluents into the Arkavathi river. In this study, the water samples are collected from 8 selected sampling stations of Arkavathi River during the study period of post monsoon month in February 2020 for physio-chemical analysis and the Water quality index developed for the water samples. According to the NSF, surface water quality of overall Arkavathi River, was mainly assessed as bad quality since the value was between 35 to 45. This research analyzed the current situation of Arkavathi river pollution, and summarized the researches on river pollution control and remediation. The remediation aims to better the quality of river by enabling it to be used for domestic and agricultural purposes. After comparing and analyzing different techniques and clarifying the concepts of remediation technology, based on the advances of river remediation, and its approaches to alleviate the river pollution problem that plagues the Arkavathi River.
