Evaluating household water treatment options: health-based targets and microbiological performance specifications

This document by the World Health Organisation, for the first time, sets forth global criteria to evaluate whether a household water treatment option reduces waterborne pathogens sufficiently to protect health. Through use of a risk-based framework and by emphasizing the philosophy of incremental improvement, it is intended to provide implementers and policy-makers with an evidence-based and pragmatic approach to select options suited to local conditions.
