drinking water quality can be deteriorated by microbial and toxic chemicals during transport, storage and handling before using by the consumer. this study was conducted to evaluate the microbial and physicochemical quality of drinking water from bottled water coolers.a total of 64 water samples, over a 5-month period in 2012-2013, were collected from free standing bottled water coolers and wat...

The main points of interest of this paper are several uranium mines in Western Saxony which have been flooded or are in a flooded state.

Abstract This paper reviews the early history (first 20 years) of passive treatment mine water, from its beginnings, when it was viewed as a possible way to treat small flows circumneutral and mildly acidic coal drainage, use for much larger more contaminated water metal mines. The original concepts have since been modified used successfully wide range quality quantities, far than we would beli...

theoretical review of ‘mining pit lakes’ indicates that like natural lakes such lakes display a huge diversity. they are typically in a non-equilibrium state with respect to their surroundings. hence, at the decommissioning phase of mining operation a detailed technical study are required on different aspects of such created water bodies considering its morphometry, geology, hydrology, water qu...
