Status of Ground water Quality, Hoskote Taluk, Bangalore Rural District, Karnataka, India. International Research

The quality of groundwater in nature is determined by quantum and nature of recharge, chemical composition of the soil cover and its thickness, mineralogical make up of the aquifer, residence time of the water which is governed by the transmissivity of the formation. The two important characteristics of the crystalline terrain, which covers practically the entire Taluk, are the heterogeneity and preferred flow paths. They have a dominant role to play in determining the quality of the ground water with the result; large variations are noticed in short distances. Thus it is not uncommon to get varied quality of water even in a small village. This fact is to be borne in mind while locating sources of water supply for various uses

Ground water Quality Report at M.V.J.Medical College, Dandupalya, Hoskote Taluk

Water and health are inter-twined in many ways and it is important to address the increasing need for adequate and safe water to protect both the people and the planet. Water is one of the earth’s most precious and threatened resources and health is each one of our most precious resource. Hence we need to protect and enhance them both. In the recent years, groundwater in the study area forms the mainstay of drinking water supply for meeting the community needs. But the threat of groundwater contamination is looming large over the study area. Contamination of groundwater source could occur due to pollution from industrial, agricultural and community living. Also, geology of the region has an important bearing on certain dissolved constituents in the groundwater supply, in particular like fluorides. In view of this, it is of paramount importance to look for and to evaluate the physico-chemical and bacteriological parameters in the drinking water of the area and assess their status of potability in the light of the criteria laid by Bureau of Indian Standards (B.I.S)

Trends of observation on wells, Remedial measures and feasibility studies of Hoskote taluk, Bangalore rural district, Karnataka, India

Hosakote is a Taluk in Bangalore Rural District. It’s headquartered at Hosakote town, 25 km away from Bangalore City.Currently, Hosakote depends on ground water (bore wells) as the main source of water supply. Due to depletion of rainfall year by year,overexploitation a n d less recharges, the yield from the borewells are diminishing considerably. In summer season, the water table goes much below thus creating scarcity of water. Hence, the ground water source is not dependable and there is an inevitable need to develop a project for alternate source of water supply. And as such this p a p e r presents the water problems in the Taluk, the reasons for the problems and remedies to correct the problems. The scope of this paper includes: i. Profiling of Hosakote Taluk and understanding their water requirements and demands. ii. Identifying environmental and social impacts of the suggested remedies and to suggest mitigation measures to overcome these impacts. A preliminary feasibility report entitled, Integrated Water Supply project for Hoskote Town (2012), prepared by Infrastructure Development Department (IDD), Government of Karnataka, presents the water supply system and scenario of the Taluk. The primary objective of the project is to explore feasibility to cater to existing & future water demand of Hosakote City by providing treated water from Doddakere Lake while supplementing the source of incoming water to the lake with water from Bellandur Lake after tertiary treatment. Bellandur Lake receives water primarily from Koramangala- Challaghatta Sewage Treatment Plant (STP) which treats the sewerage to tertiary level. A report entitled Ground Water Information Booklet, Bangalore Rural District; prepared by Central Ground Water Board, Ministry of Water Resources, Government of India, reports that most of Karnataka State’s ground water is in critical condition. It addresses the need to stop exploration of ground water and presents ways to improve the water resources of the Taluk
