This study was initiated to determine the usefulness of Coli ID agar in
recovering chlorine-stressed E. coli and other coliform organisms from drinking
water and to compare the results with Tergitol-TTC agar stipulated by European
Guideline 98/83 as a reference method. Moreover, the Colilert-18 /Quanti-Tray
medium was used. To that end, the study analyzed marginally chlorinated water
samples by means of the most probable number method using Colilert-
18 /Quanti-Tray, and the membrane
filtration technique using Coli ID and TTC-Tergitol agar, according to ISO 9308-
1:2000 method for coliforms and E. coli. Variance analysis of the data obtained
showed statistically significant differences in the coliform counts "confirmed" on
Coli ID compared with this of reference method used. The coliform counts on
Coli ID from marginally chlorinated water samples were significantly greater
