Abstract
A test kit and method particularly for the quantitative determination of total coliform bacteria and E. coli particularly in large volume test samples, such as water, wherein the media includes an agent which changes color and a gelling agent which reacts or provides in situ with the test sample a semi-solid broth or media for incubation, thereby restricting the mobility of the growth bacteria and permitting a quantitative count of the separate, colored bacteria colonies.
