Science-based” standards are an integral part of modern regulatory systems. Studies on “public understanding of science” mostly focus on high technology areas in advanced economies. In contrast, the present study analyses the public understanding of regulation in the context of standard-setting for bottled water quality in India. Using primary data, the econometric models of this paper show tha...

Chemical and microbial characteristics of the samples were examined and determined. Finally, the ca...
The number of states that have adopted numeric nutrient water-quality standards has increased to 23, up from ten in 1998. One state with both stream and reservoir phosphorus (P) numeric water-quality standards is Oklahoma. There were two primary objectives of this research: (1) determine if Oklahoma was meeting the stream and reservoir numeric water-quality standards in the Illinois River and E...
