Assure Controls uses a patented technology that allows rapid onsite detection of contaminants at toxic levels in water and soils. Our QwikLite™ Testing System uses sensitive bioluminescent plankton in small cartridges to assess both inorganic and organic substances. When exposed to substances, as toxicity increases, bioluminescence decreases. The U.S. Navy conducted the original research, discovered this relationship, and Assure Controls received the exclusive commercial rights.
