Currently, no federal policies exist in the United States regarding private wells; this authority is devolved to states. This study inventoried state-level policies governing private wells in the United States in order to identify the topics addressed by each state, division of responsibilities across state agencies, and geographic differences in policy comprehensiveness. From May to August 2016, two independent reviewers conducted an online search followed by directly contacting state agencies (98% response) to identify all state-level policies in the United States that directly reference private wells. The search, updated in April 2018, confirmed the existing water policy list and identified 23 additional policies. Policies were then coded according to nine not-mutually-exclusive classifications. The results indicate that all states had at least one policy addressing private well drilling or construction. Significant geographic differences exist in maintenance-related policies. In conclusion, although drilling and construction safety are addressed by each state, some policy domains are addressed inconsistently across states, and other policy domains are absent in most states.

Scholars and practitioners advocate evidence-based decision-making (EBDM) because facts lead to beneficial outcomes. At the same time, EBDM to reduce risks in water quality is under-studied. We examine types of decision-making by water utilities and government agencies, and the nature and origin of evidence available to them in their work on delivering safe drinking water to households. Using qualitative content analysis, we comparatively analyze water utilities and government agencies in Malawi, Ecuador, and Brazil. The results show that the water utilities perform combinations of decision-making types on water quality such as implementation, intelligence-gathering, and evaluation and choice, while government agencies perform more intelligence gathering. Sources and types of information are mainly water consumers, guidelines for water quality standards, and self-monitoring from water utilities. The analysis is useful in establishing a foundation for developing evidence-based management within water supply services, and potentially other water resources management activities.

With water and sanitation vital to the public's health, there have been growing calls to accept water and sanitation as a human right and establish a rights-based framework for water policy. Through the development of international law, policymakers have increasingly specified water and sanitation as independent human rights. In this political development of human rights for water and sanitation, the authors find that the evolution of rights-based water and sanitation policy reached a milestone in the United Nations (UN) General Assembly's 2010 Resolution on the Human Right to Water and Sanitation. By memorializing international political recognition of these interconnected rights and the corresponding obligations of national governments, states provided a normative framework for expanded efforts to realize human rights through water and sanitation policy. Examining the opportunities created by this UN Resolution, this article analyzes the implementation of the human right to water and sanitation through global water governance, national water policy and water and sanitation outcomes. While obstacles remain in the implementation of this right, the authors conclude that the UN Resolution could have lasting benefits for public health.
