چکیده انگلیسی
A total of 3086 samples, both marine (2916) and freshwater creeks/outfall samples (170) were collected and analyzed for enterococci during October 2002-April 2005, from 52 designated beaches in Oregon. A total of 3.2% (99/3086) of the samples at 21 beaches exceeded 158 most probable number (MPN)/100 milliliters (mL). The average enterococci levels of these 99 exceedances was 559Â MPN/100Â mL, with a maximum of 4352Â MPN/100Â mL (Otter Rock and Ona) and a minimum of 160Â MPN/100Â mL (Sunset Bay State Park, Bastendorff, and Mill). For marine water, 77/2916 (2.6%) exceeded 158Â MPN/100Â mL. For freshwater, 22/170 (12.9%) exceeded 158Â MPN/100Â mL, with a maximum of 587Â MPN/100Â mL at Sunset Bay. Sixty percent of the marine and 9% of freshwater exceedances occurred during the winter. Seventy-two percent (55/77) of the marine exceedances occurred after rainfall events (0.01-60.0Â mm). At Harris and Mill Beaches, cumulative rainfall was highly correlated with bacterial densities, RÂ =Â 0.7. Rainfall, at both beaches, explained about one-half the variation in log10 bacteria density (R2Â =Â 0.5). Additional monitoring is warranted to further characterize bacterial contamination in Oregon waters.
