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

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
Nitrate levels in Hoskote taluk, Bangalore rural district, Karnataka,
Hoskote Taluk is one of the eight Taluks of
Bangalore Rural District in Karnataka with a current
approximate population of 3, 03, 428; the total water
demand comes out at around 49.5 MLD @ 135 LPCD, (WHO
Standard).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

In view of this, it is of paramount importance to look for and to evaluate the Nitrate levels 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).
Nitrate disease caused by excess intake of Nitrate. Results
show that there is a definite contamination of ground
water in the study area with respect to Nitrate and a clear
correlation between the ill health faced by the public and
ground water contamination is notice

Agronomic and environmental implications of enhanced s-triazine degradation
Novel catabolic pathways enabling rapid detoxification of s-triazine herbicides have been elucidated and detected at a growing number of locations. The genes responsible for s-triazine mineralization, i.e. atzABCDEF and trzNDF, occur in at least four bacterial phyla and are implicated in the development of enhanced degradation in agricultural soils from all continents except Antarctica. Enhanced degradation occurs in at least nine crops and six crop rotation systems that rely on s-triazine herbicides for weed control, and, with the exception of acidic soil conditions and s-triazine application frequency, adaptation of the microbial population is independent of soil physiochemical properties and cultural management practices. From an agronomic perspective, residual weed control could be reduced tenfold in s-triazine-adapted relative to non-adapted soils. From an environmental standpoint, the off-site loss of total s-triazine residues could be overestimated 13-fold in adapted soils if altered persistence estimates and metabolic pathways are not reflected in fate and transport models. Empirical models requiring soil pH and s-triazine use history as input parameters predict atrazine persistence more accurately than historical estimates, thereby allowing practitioners to adjust weed control strategies and model input values when warranted
