These bacteria were originally believed to indicate the presence of fecal contamination, however total coliforms have been found to be widely distributed in nature and not always associated with the gastrointestinal tract of warm blooded animals. Rapid analytical methods, such as quantitative polymerase chain reaction (qPCR) and immunomagnetic separation/adenosine triphosphate (ATP) analysis, are being tested but are not yet ready for widespread use.Another solution is the use of, The Lake Erie beaches in Pennsylvania are a valuable recreational resource for Erie County.

The USGS Pennsylvania Water Science Center is working with Erie County Department of Health, Pennsylvania Department of Conservation and Natural Resources at Presque Isle State Park, and Regional Science Consortium at the Tom Ridge Environmental Center to expand the use of operational nowcast systems (based on predictive models) to Presque Isle State Park beaches. Current bacteria conditions are estimated using a predictive regression model that utilizes weather and environmental data to predict whether or not E. coli levels will exceed an established threshold and a beach closing or water-quality advisory needs to be issued.

A more rapid method that some managers of recreational waters have adopted is the use of water-quality and environmental variables as surrogates for fecal-indicator bacteria that include, for example, precipitation, wind speed and direction, streamflow, wave height and turbidity to predict when concentrations of fecal-indicator bacteria will exceed recreational standards. The Texas Department of State Health Services also found that some species of fish in Lake Livingston had elevated levels of dioxins and polychlorinated biphenyls (PCBs) that would pose a risk to human health if people were to consume those fishes. The population of planet Earth is growing rapidly and every year the number of inhabitants increases by 1.1 percent or by 75 million per year. account_circle They use mathematical models and techniques to provide near-real-time estimates of fecal-indicator bacteria (FIB) and cyanotoxin concentrations.
