The present study designed for quantitative estimation of some essential trace elements from natural sources like well, bore well and river from different regions of Nagpur district like Kamptee (21.2275ºN, 79.1901ºE), Kanhan (21.2297ºN, 79.2381ºE), Parsheoni (21.3757ºN, 79.1520ºE) and Nagpur (21.1412ºN, 79.1260ºE). In this study Bureau of Indian Standard (BIS) guidelines and parameters were followed for determination of essential trace elements which includes calcium, zinc, copper, chloride and nitrate using UV/VIS spectroscopy, titrimetry and other evaluation methods which include microbial testing were used. Concentration of essential trace elements like calcium, zinc, chloride, copper and nitrate were found high in water samples of well than bore well in all four regions. Microbial testing showed that none of the water samples of all four regions are safe or fit for drinking unless otherwise purification systems are not used. Further water samples from Nagpur and Kamptee regions showed significant low concentration of all elements. It has been concluded from the study that water from well and river is rich in essential elements but within the range compared to bore well may because of geographical condition and depth of bore-well to fetch water. Further population residing especially in Kamptee and Nagpur regions requires parallel consumption of supplementary products apart from food, dairy products, and water to fulfil the adequate intake of essential trace elements.
