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
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 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
