Spatio-temporal investigation of E-coli contamination of tributary creeks: from Tallaseehatchee to the Coosa.

SPATIO-TEMPORAL INVESTIGATION OF E-COLI CONTAMINATION OF TRIBUTARY CREEKS: FROM TALLASEEHATCHEE TO THE COOSA. KAILA BROWN PHYSICAL AND EARTH SCIENCE. JACKSONVILLE STATE UNIV. JACKSONVILLE, AL 36265. LARRY J. MORGAN, JACKSONVILLE, STATE UNIVERSITY, JACKSONVILLE, AL 36265

In an attempt to determine the level and potential origins of bacteriological contamination in the local tributaries of Tallaseehatchee Creek in Jacksonville Alabama a one-year preliminary study was conducted. Two of the three tributaries are identified as public use or park areas. The third is a drainage area passing under Hwy 204 east of Gadsden Rd. The project was specifically designed to determine the levels and potential origins of Escherichia coli, also known as E. coli bacteria in these three creeks. All three are tributaries to Tallaseehatchee Creek which serves points west of Jacksonville eventually dumping into the Coosa River. Using the Alabama Water Watch (AWW) bacteriological monitoring standards and monitors certified by AWW, samples were taken monthly for each of the monitor sites and processed according to rigid standards. E. coli colonies were counted from test samples collected from the tributaries. This study found varying elevated levels of E. coli bacteria in the water bodies. Descriptive statistics have shown what appear to be temporal and spatial patterns of E coli distribution in this environment. While none of the sites have shown presence of E coli at levels high enough to create an alarm the values detected in some cases were high enough to raise concerns. Statistical analyses of the three sites have indicated statistically significant seasonal levels when compared to all monthly levels. Ground truthing and high-resolution Landsat ETM+ imagery along with evaluations of the agricultural calendar will be used to evaluate land-use land-cover (LULC) in the drainages areas of the test sites.
