Water Works Bacteria Water Test detects presence of Coliform and E.Coli Bacteria in water. Ideal for service technicians and home owners, test uses a standard presence / absence growth media to give results in only 24-48 hours with no incubation required.
Designed to measure the US EPA standard of 1 colony per 100mL of water, EZ Coliform Bacteria Water Test is the safe, affordable way to identify contaminated drinking water and determine the need for bacteria treatment.
We also have a 12-test kit available.
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 is 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 included with this test.

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.”
This Test Kit is EPA Compliant. Follows the APHA, Standard Methods, 20th Edition, 9221 D, screen test for total coliform in potable water.
