Customer Testimonials

“We selected the Aquagenx CBT E. coli Kit as our microbiological water quality test after an exhaustive study of available tests. Nothing matches its ease-of-use and reliable quantitative results, or its cost effectiveness, especially for low resource, rural areas. We are excited to partner with Aquagenx for the Sierra Leone survey. By combining the easy-to-use Aquagenx CBT with the Akvo Caddisfly app, we are able to give communities in remote areas instant and valuable feedback on drinking water safety based on WHO health risk categories. Therefore, the test results can be optimally used both at the national and local level.”

Mert Blommestijn
Akvo Foundation

“WaterAid’s use of the Aquagenx CBT Kit in the Asia and Pacific regions has been very successful and has greatly improved WaterAid’s water quality monitoring capacity. Our staff and partners like the simplicity of the CBT Kit and the fact that anyone can undertake E. coli testing with very basic training and capacity.”

Tim Davis

“The Aquagenx CBT is perfect for large field surveys and pairs very well with the mWater platform. Together, the CBT Kit and the mWater app provide a very simple workflow that reduces training time, equipment cost and sophistication, and testing turn-around time.”

Brian Jensen
Haiti Outreach

“The CBT should be adopted for standard water quality testing practices and disaster response within the Red Cross/Red Crescent movement and used by all member societies working in a water supply capacity. The CBT’s speed, convenience and quantitative test results add value to water quality investigations and validate projects and programs, It is simple to use on-site in remote locations, and its color-change test results are an excellent way of raising water quality awareness for local communities.”

Stuart Bryan
International Federation of Red Cross

“The CBT lets us mobilize resources and make informed decisions very quickly in the face of a disaster. We will continue to use the CBT in other disaster settings because of its ease of use and handling, low cost and efficiency.”

Jay Matta
International Federation of Red Cross

“Having no prior training or knowledge of these kinds of water quality tests or the methodology behind results evaluation, our teams found the Aquagenx testing equipment to be very user-friendly. Using the educational materials provided by Aquagenx, we have been able to deliver the test results to our clients in a simple, direct and easy to understand fashion. Aquagenx products are easy for our team to use, and the results are fast and easily deliverable to our clients. Additionally, the professionalism and personalized care with which representatives from Aquagenx have shown in working with our team are second to none.”

“The Aquagenx CBT E. coli Kit is ideal for household water quality surveys because it’s easy to use and obtain test results in rural areas without electricity and other resources. It’s easy to explain how the CBT Kit works, and the test makes it simple to explain water quality basics. Its color-change test results are a visual, dramatic way to show community members how safe or unsafe their water is to drink.The CBT Kit is excellent for household testing because you don’t have to be a WASH specialist to use it. It’s very compact and lightweight and no extra equipment is needed. The CBT’s price is reasonable especially considering its capabilities for on-site testing in rural, remote areas. We’ll definitely continue using the Aquagenx Compartment Bag Test. It’s important for us to do ongoing water quality monitoring in these communities with the CBT Kit to ensure people understand the importance of drinking clean water, and to show local people the results and impacts of this big project.”

Jackeline Brincker
Universidad del Valle de Guatemala

“The Aquagenx CBT E. coli Kit is wonderful. It is easy to use and lets us quickly read test results by the next day. The CBT Kit is small and easy to carry into the field. There are many advantages to using the CBT E. coli Kit, including the fact that its testing procedure is adaptable to long field days and requires minimal laboratory availability. We will absolutely continue using the CBT E. coli Kit for our work in Cuba and other projects around the world”

Paul Bierman
University of Vermont

““The Aquagenx CBT is the best water quality test on the market for this type of study. It’s easy to use, easy to transport and easy to interpret test results. The CBT is ideal for onsite testing in remote areas because it provides reliable results and doesn’t require specialized knowledge or equipment to use. It has a small number of incubation requirements so it’s very flexible in low resource areas.”

Ryan Schweitzer

“We will absolutely continue using the CBT. It’s a great test because it’s easy to use, provides test results quickly and requires very few materials.”

Juri Wawra

“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 because it helps us guarantee the quality of water and tells us which waters are safe and which are not.”

Vann Chhorvy Vanny
Clear Cambodia

“We will absolutely continue using the CBT in our projects to test for E. coli. It’s very easy to use, and even the village children in Tanzania learned to use it! The CBT is cheap, reliable, easy to transport and easy to understand.”

The CBT Kit provides quick turnaround time on results, is easily transported and is easy to use in sample preparation. In addition to its low cost and rapid results, the portability of the CBT is a benefit, along with its simplicity of use.

Bill Clunie

“I would recommend the CBT to anyone who needs to perform microbiological testing on groundwater, surface or drinking water, and needs to do this accurately, inexpensively and simply. The CBT Kit offers the same level of accuracy as laboratory analysis at a fraction of the cost, and without the additional steps and hassle of transporting the samples to the lab. Being able to read the results immediately after incubation within 24 hours is a huge benefit.”

Dave Robbins
RTI International

“The CBT is easy to use, especially for carrying out water testing in-the-field where anyone can use it with little training”

Risyana Sukarma
Yayasan Tirta Indonesia Mandiri

“The CBT is easy-to-use, and is a great, simple way to measure the presence of bacteria in the raw water samples in Haiti. It was easy to pack and easy to carry around to collect the water samples during my trip. I would recommend this test for use in any third world country.”

Amanda Costello
Purdue University

“The CBT Kit’s quantified test results give us the data we need and guides our thinking about disinfection effectiveness.It is simple to use on-site in remote locations.”

Paul Berg

“The CBT is the only product I’ve found that is suited for water quality testing in the Amazon. No temperature control or laboratory are needed, two things that do not exist in rural communities of the Amazon.”
