Comparing Rapid And Culture Indicator Bacteria Methods.

5/6/2013 -- At 3 inland lake beaches in Ohio concentrations of indicator bacteria by culture were compared to concentrations by a rapid analytical method, quantitative polymerase chain reaction (qPCR). All of the qPCR results exceeded the new U.S. EPA beach action values (BAVs) for Enterococcus spp. by qPCR, whereas only 23.7% of culture results for E. coli and 79% of culture results for enterococci exceeded the current standard for E. coli or BAV for enterococci. The authors conclude that replacing current E. coli standards with BAVs for enterococci by culture or qPCR may result in more advisories being posted at inland recreational lakes. Results of the study were published in an article in the journal Lake and Reservoir Management.

Measuring The Flow: The Importance And Uses Of Streamflow Information.

3/29/2013 -- Everyone in society benefits from reliable streamflow information used for flood warnings, drinking-water management, bridge design, recreation, and much more. USGS works in partnership with more than 850 Federal, State, Tribal, and local agencies and collects streamflow data at more than 8,000 streamgages nationwide. Learn more in this two part USGS Science Top Story: Measuring the Flow, part 1: The Importance of Streamgages and Measuring the Flow, part 2: Uses of Streamflow Information. The USGS remains dedicated to providing its stakeholders and the public with continuous, well-documented, well- archived, unbiased, reliable, and consistent streamflow information.
