When testing water using color changing reagents, save money with the Whirl-Pak Coli-Test sample bag. It is made of a special film that is compatible with enzyme-based methods that result in a chromogen and/or fluorogen release when total coliform and E. coli are present, and is listed in the 2005 EPA Drinking Water Manual for Laboratory Certification.
