COMPARISON OF ESCHERICHIA COLI, TOTAL COLIFORM, AND FECAL COLIFORM POPULATIONS AS INDICATORS OF WASTEWATER TREATMENT EFFICIENCY
Elmund, G. K., M. J. Allen, AND E W. Rice*. COMPARISON OF ESCHERICHIA COLI, TOTAL COLIFORM, AND FECAL COLIFORM POPULATIONS AS INDICATORS OF WASTEWATER TREATMENT EFFICIENCY. WATER ENVIRONMENT RESEARCH. WEF, Alexandria, VA, 71(3):332-339, (1999).
Escherichia coli, total coliform, and fecal coliform data were collected from two wastewater treatment facilities, a subsurface constructed wetlands, and the receiving stream. Results are presented from individual wastewater treatment process streams, final effluent and river sites up- and downstream of the treatment facilities. The QuantiTray technique with Colilert media was a precise method for quantifying E. coli and total coliform populations in these waters. Results may facilitate the development of E. coli-based effluent and stream standards to protect the public health.
