Coliform Bacterial Contamination in Tanyard Creek
Fecal-Coliform Bacterial Concentrations
In
Tanyard Creek
by
John A. Allen
Introduction
On March 3rd our lab assignment was to walk to Tanyard Creek, located near the Tate Center parking lot, on the campus of the University of Georgia. We took measured many water quality parameters at or near base flow; conductivity, dissolved oxygen, phosphate, nitrate and silica, pH, alkalinity and turbidity. Samples were taken at both low and high flow conditions to measure the total …
