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
