This paper provides the first estimates of the contemporaneous effect of drinking water quality violations on students' academic achievement. Using student-level test score data with residential addresses, geographic information on water systems, and drinking water violations from North...

Previous research in the US has found negative health effects of contamination when it triggers regulatory violations. An important question is whether levels of contamination that do not trigger a health-based violation impact health. We study the impact of drinking water contamination in...

Our understanding of individuals' response to information about unregulated contaminants is limited. We leverage the highly publicized social discovery of unregulated PFAS (per- and polyfluoroalkyl substances) contamination in public drinking water to study the impact of information about...

Transboundary spillovers may degrade environmental quality if countries free ride. This paper examines the extent of such degradation in water quality in international rivers. Using data from river monitoring stations in the UN's Global Emissions Monitoring System (GEMS), it compares pollution...

In the half century since the founding of the U.S. Environmental Protection Agency, public and private U.S. sources have spent nearly $5 trillion ($2017) to provide clean rivers, lakes, and drinking water, or annual spending of 0.8 percent of U.S. GDP in most years. Yet over half of rivers and...

The recent drinking water crisis in Newark, New Jersey's largest city, has renewed concerns about the lead-in-water crisis becoming a persistent and widespread problem owing to the nation's aging infrastructure. We exploit a unique natural experiment in Newark, which exogenously exposed some...

This article proposes and evaluates four hypotheses about US pollution and environmental policy over the last half century. First, air and water pollution have declined substantially, although greenhouse gas emissions have not. Second, environmental policy explains a large share of these trends....

This paper examines whether risk-based pricing promotes risk-reducing effort. Such mechanisms are common in private insurance markets, but are rarely incorporated in government assurance programs. We analyze accidental underground fuel tank leaks--a source of environmental damage to water...

This paper explores the empirical effects of decentralization on environmental quality by studying water pollution in rivers around the world. It examines the level of pollution and variation in pollution across jurisdictions within a country, for both a local and a regional pollutant. Federal...

Beginning around 1880, public health issues and engineering advances spurred the installation of city water and sewer systems. As part of this growth, many cities chose to use lead service pipes to connect residences to city water systems. This choice had negative consequences for child...
