Applications
- Initial screening test. H2S-positive results can be followed by testing the same water for
E. coli with our CBT EC+TC Kit for more specific evidence of fecal contamination - If the alternative is no water quality testing. It is highly beneficial from a health perspective to test for H2S bacteria rather than not doing any water quality testing.
- Microbiological testing to validate the efficacy of water disinfection and treatment methods
- Behavior change and educational tool and activities that promote water, sanitation and hygiene
