How To Use EZ Coliform Cult Bacteria Water Test Kit
Simply fill the sterile bottle with your water sample, cap, and leave in an unobtrusive, room temperature location.
To test for Coliform:
Media will turn clear yellow if coliform is not present (negative), or blue-green if coliform present (positive)
To test for E.Coli:
Shine UV light (approximately 365mm) from the bottom of the sample (avoid looking directly at the light).
No fluorescence = negative for E.Coli
Blue fluorescence = positive for E.Coli
Presence of E.coli can also be confirmed using Kovacs Indole Reagent (which has to be refrigerated, one of many other names is "Kovac's Aldehyde reagent"). The UV Light and Kovacs Indole Reagent are not inclided with this test.
WaterWorks EZ Coliform Cult (X-GAL / MUG ) water test has replaced older WaterWorks Bacteria Check Test kit. WaterWorks bacteria check test kit (see picture on the right) is no longer available.
A comparison study performed by an outside laboratory in April, 2008 concluded the ITS EZtm Coliform Cult was “equally effective as the Readycult® system in the simultaneous detection of Total Coliform and Escherichia-coli at the concentration of 10 CFU/100mls.”
WaterWorks EZ Coliform Cult Bacteria Test Kit is EPA Compliant.
