This study considers water use by Canadian manufacturing firms. The estimation of water demands is based on a detailed crosssectional survey of establishment-level observations on water prices, quantities, and expenditures. Industrial water use is modeled as having four components: intake, treatment prior to use, recirculation, and discharge. Average values for the estimated own-price elasticit...

Water is a valued natural resource for the existence of all living organisms. Indian rivers are polluted due to the discharge of untreated sewage and industrial effluents. Management of the quality of this precious resource is, therefore, of special importance. In this study river water samples were collected and analysed for physicochemical and bacteriological evaluation of pollution of Kausha...
