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 use ofE. colias an indicator of recreational water quality has been largely effective in determining when fecal contamination is present; however, there are drawbacks with using it as the only indicator. Below are other science projects associated with this project. As opposed, Grapevine Pond is 9 feet underneath standard. Children under 13 years of age must have a parent/guardian's consent before providing These models use turbidity and other data to compute the estimated E. coli levels at the USGS station locations. CLEAN, DRAIN AND DRY your boat, trailer, livewells/bait buckets, and other gear before traveling to another water body. The U.S. Geological Survey is collaborating with State and local partners to develop models that provide real-time estimates of Escherichia coli (E. coli) (for pathogens) and (or) microcystin (for freshwater cyanotoxins) levels at Great Lakes beaches and drinking-water intakes. Contact rsyoung@usgs.gov Medlock Bridge: 02335000 Paces Ferry: 02336000 Predictive models have been used at beaches to improve the timeliness and accuracy of recreational water-quality assessments over the most common current approach to water-quality monitoring, which relies on culturing fecal-indicator bacteria such as Escherichia coli (E.
