Microbiological indicator testing is a crucial tool for household water treatment and safe storage (HWTS) program implementation, monitoring, and evaluation. Absence of microbiological contamination is an indication that water is safe to drink, and, correspondingly, presence of microbiological contamination indicates drinking the water may cause diarrheal disease.

This fact sheet is intended to provide guidance for researchers, practitioners, evaluators, and other parties interested in testing for microbiological contaminants in developing countries. This fact sheet begins with why we test for microbiological contaminants, and continues through to recommendations for selecting a testing method for specific circumstances. Sample testing procedures are appended at the end of the document.
