Drinking water Technology, Eawag, developed a method by which hazard maps could be produced for geogenic toxic substances in groundwater. This provides an efficient way of determining which wells should be tested. Parameters for drinking water quality typically fall within three categories: Physical and chemical parameters include heavy metals, trace organic compounds, total suspended solids (TSS), and turbidity. Microbiological parameters include Coliform bacteria, "E. coli", and specific pathogenic species of bacteria (such as cholera-causing "Vibrio cholerae"), viruses, and protozoan parasites. Chemical parameters tend to pose more of a chronic health risk through buildup of heavy metals although some components like nitrates/nitrites and
Yeşilçay Drinking Water Plant remarkable engineering projects realized in the first 50 years of the chamber. Yeşilçay Drinking Water Plant Yeşilçay Drinking Water Plant is a plant used to supply drinking water to İstanbul, Turkey. The total population of İstanbul is 13 483 052 (as of 2011) which makes İstanbul one of the most populous cities of the world. The rate of annual increase is about 3.45% and the water demand is increasing asymptotically. So one of the most important problems of the municipality is to meet the demand. Yeşilçay is a river at about east of Anatolian quarters of İstanbul. The headwaters are
