Can sanitary surveys replace water quality testing?
Developed by the World Health Organization (WHO), sanitary surveys are observational checklists to assess hazards present at water sources. Sanitary surveys are cheaper and faster to conduct than microbial water quality tests, as they require no special equipment. To assess whether sanitary surveys can be a substitute for microbial water quality tests, Aquaya researchers published a comparison of sanitary risk scores and fecal contamination levels in water sources in rural Kenya.
