Protecting drinking water: water quality testing and PHAST in South Africa

The paper presents an innovative field-based programme that uses a simple total coliform test and the approach of PHAST (Participatory Hygiene And Sanitation Transformation) to help communities exploring possible water quality problems and actions that can be taken to address them. The Mvula Trust, a South African water and environmental sanitation NGO, has developed the programme. It is currently being tested throughout South Africa. The paper provides two case studies on its implementation in the field, and suggests ways in which the initiative can be improved in the future.
