How do you know if drinking water is safe? Or which microbial indicator tests work best when few side-by-side performance evaluations exist in real-world field sites? This research compares bacterial indicator test products inlow-resource settings in Ahmedabad, India and Tamale, Ghana. In India, three hydrogen sulfide (H2S) bacteria test products were evaluated: laboratory-made H2S, TARA Aquacheck and ORlab H2S, and compared to an EPA-certified standard, the IDEXX Quanti-Tray® 2000. In Ghana, 3 M Petrifilm™, Aquagenx CBT and Easygel® Cards were included in addition toH2S and Quanti-Tray® 2000. Results are presented in a Consumer Reports-style for easy comprehension.
