Comparative Evaluation of Risk Management Frameworks for US Source Waters

Programs to manage risks to drinking water sources have expanded globally in the past 20 years, and could offer benefits to U.S. utilities. This participatory study compared candidate frameworks and practitioner interviews with evaluation criteria matched to implementation theory. Weighted integration using stakeholder survey responses and input from a decision-making workshop helped to rank relative applicability. The findings recommended hybridizing the American National Standards Institute/American Water Works Association (ANSI/AWWA G300) source water protection standard and World Health Organization Water Safety Plan guidance, as well as incorporating financial considerations into risk ranking and mitigation decisions.
