AbstractHaving safe drinking water and basic sanitation is a human need and right for every man, woman and child. Still millions of people are exposed to unsafe levels of chemical contaminants in their drinking water, which have been associated with serious health implications. WHO in 1948 come up with an objective of promoting ’the attainment by all peoples of the highest possible level of health.’ In milieu, water from natural sources such as River, Well, Bore-well, purified by means of electric equipment Reverse Osmosis (RO) and Ultra-violet techniques, provided by Municipal Corporation (MC), and Packaged Drinking Water (PDW) were comparatively and quantitatively evaluated from Kamptee region (21.333°N, 79.2°E).
All parameters were evaluated as per BIS 10500, pH of water samples were found to be within limit (6.5 to 8.5). Odour was agreeable except well and river which smells chlorinous and fishy respectively. Turbidity limit (10 NTU) was crossed by river, well and bore-well samples. Hardness was within the acceptable limit (200 mg/L) while undesirable substances such as calcium, chloride, nitrogen, copper, magnesium were within the specified limit 75 mg/L, 250 mg/L, 45 mg/L, 0.05 mg/L, 30 mg/L respectively whereas sulphate content obersered higher in river, well and bore-well samples. Mercury was under limit (0.001 mg/L). Microbiological study revealed that all water samples were safe except water from natural sources. Comparative and quantitative evaluation of water samples from different sources showed that RO, UV, MC, PDW water samples are the best sources for water consumption. Considering health, water with depleted minerals obtained from RO not fit for drinking, so such depletion of minerals was fulfilled by mixing municipal corporation (MC) water in ratio of 80:20 (RO: MC) showed best source for drinking irrespective to taste, odour, turbidity, mineral contents and microbial contamination.
