The distribution of fecal coliforms was investigated and determined in Izmir Bay from 1996 to 2005. Izmir Bay severely was polluted from industrial and domestic discharges during decades. In early 2000, a wastewater treatment plant began to treat domestic and industrial wastes. This plant treats the wastes about 80% capacity after 2001. The sampling periods cover before and after treatment plant. Assessment method for determining the number of fecal coliform has evolved membrane filtrations. Maximum surface fecal coliform concentration was 4.9 x 10(5) cfu 100 ml (-aEuro parts per thousand 1) in 1996-2000 period. Following the opening treatment system, fecal coliform density decreased 2.1 x 10(4) cfu 100 ml (-aEuro parts per thousand 1) during 2001-2005. A continuous improvement can be sustained in the water quality if direct inflow of untreated wastewater is prevented.
