E. coli Water Quality Test Kits

Aquagenx CBT E. coli water quality test kits meet World Health Organization Guidelines for Drinking Water. They are ideal for on-site water quality testing in low resource, rural and disaster/emergency settings.

The CBT Kit’s simplicity and convenience remove barriers to bacteriological water quality monitoring where testing was previously too difficult, impractical and costly. Our test generates quantified (MPN), color-change test results for E. coli without the need for labs, electricity or expensive, cumbersome equipment. The CBT enables ambient temperature incubation at 25 degrees Celsius and above, works at variable temperatures and does not require constant temperature control in an incubator.

mWater Mobile App Supports Aquagenx CBT



Aquagenx CBT Kits for E. coli are supported by the free mWater Mobile App that lets users with smartphones and tablets calculate and share CBT test results in real time, create and map water quality surveys using the CBT, plus lots more.

“Being able to perform our own reliable quantitative testing saved our organization time and money. We will continue to use the CBT because we routinely test water sources for the presence of E. coli, and we now prefer to have a clear, quantitative understanding of the magnitude of fecal contamination.”

Ted Barlow

Operation Blessing International

“The CBT builds trust for our beneficiaries by providing evidence that makes them confident our water filters generate safe drinking water. Because of its efficiency. It enables our staff to test water on-site rather than having to collect samples to be sent to a lab. We’ll continue using the CBT as our ongoing microbiological water quality test.”
