Real-Time Assessments of Water Quality--a Nowcast for 'Escherichia Coli' and Cyanobacterial Toxins [open pdf - 971KB]
From the Document: "Threats to our recreational and drinking waters include disease-causing (pathogenic) organisms and cyanotoxins. 'Escherichia coli (E. coli)' is a type of bacteria that inhabits the gastrointestinal tract of warmblooded animals, is direct evidence of fecal contamination, and is one type of bacteria used to indicate when pathogens may be present in water. Other threats to our waters include the toxins produced by some species of cyanobacteria (cyanotoxins) that can cause acute and (or) chronic illnesses. [...] Tools for real-time assessments of water quality are needed to predict when and where threats to our water resources occur. To address this need, the U.S. Geological Survey (USGS) is collaborating with State and local partners to develop models that provide real-time estimates of 'E. coli' and (or) microcystin levels at inland and Great Lakes beaches and drinking-water intakes."
