FY1999 Great Lakes Projects

Rapid E. Coli Tests

Rapid E. Coli Tests: Suitability for Swimming Beach Areas (DW14947948-01-0: $71,500)

Recipient: U.S. Geological Survey

Project Period: 10/1/99 to 5/1/02

Project Officer: David Rockwell (312-353-1373)

This research will focus on the capability of flow cytometry to determine E. coli concentration more rapidly than currently used protocols. For this purpose, a beach will be tested during the swimming season. Water samples will be simultaneously tested using cytometry and traditional filtering approach. Results from the two protocols will be compared statistically using regression analysis and paired test.
