Big Cedar Creek in Putnam County has been listed as a 303d impaired stream due to excessive fecal coliform levels. The Big Cedar Creek Watershed above the highway 129 bridge is primarily a wildlife management area with minimal livestock or human impact. Since many 303d listed streams have questionable or limited data, further field sampling is required to verify existing data or generate data to make further assessments of water quality in the impaired portion of the stream. The objective of this study was to monitor fecal coliform levels in Big Cedar Creek to determine if streams are in compliance with EPA standards. The uppermost sampling station in the National Forest contained a geometric mean for fecal coliform in excess of the 200 MPN/100 ml water quality criteria during March and June sampling periods. The sites at highway 129 bridge were above the geometric mean of 200 MPN standard during the June and September samplings. The fecal coliform geometric mean for all sites is below the guidelines of 500 MPN/100 ml in free flowing freshwater streams. Only one observation was above 4,000 MPN/100 ml (Site 7, October 10, 2002). This study provides a background estimate of fecal coliform levels in clean water streams of the lower Piedmont for future TMDL development. In addition, all P values were <0.06 mg/L, and conductivity ranged from 80 to 120 FS/cm.
