Aquagenx provides water quality test kits that are easy for anyone to use, simplify field testing and help ensure safe water for everyone.


Dr. Mark D. Sobsey, Chief Science Officer and co-founder at Aquagenx, invented the Aquagenx® Compartment Bag Test (CBT) for E. coli in the mid-2000s. He is an international authority in environmental health microbiology and virology and in water, sanitation and hygiene. Dr. Sobsey was Kenan Distinguished Professor of Environmental Sciences and Engineering in the Gillings School of Global Public Health at University of North Carolina Chapel Hill, where he taught from 1974-2018. He currently serves on global committees and working groups in water, sanitation and hygiene.

Aquagenx, LLC was created in 2012 to commercialize, manufacture and distribute the Compartment Bag Test. Since January 2013, we have shipped our test kits throughout the world. We continue to develop and introduce new, simple water quality test kits that are used for an expansive array of testing applications in a variety of settings and locations.
