I'm trying to get my money back. I may have received old test kits but they gave negative or negligible results for all the results tested. Of particular note, the tests in the photos show 4 water samples each tested with 3 tests (12 sets) showing negative results for bacteria. In other words, after 48 hours, all samples were still purple and not yellow. I tested the same samples in our water treatment plant. Photos from the Q-Trays show that one of the water samples tested positive for bacteria (common E. coli and E. coli). The water sample was taken from the Chesapeake Bay. The image on the Q-Tray showing yellow is a common E. coli and the image showing the UV fluorescence is from E. coli. We bought these tests for my sixth grade science project. We were disappointed. Even tests for chlorine using test kits came back negative, while water treatment equipment tested positive for chlorine in samples of tap water and filtered water. Again, the test kits used all the same water samples from the treatment plant, in the same containers, from the same sources, at the same time. i just want my money back It was a big investment in my child's water testing project and it would have failed without the help of our water treatment facility.
