Objective:
This research investigates several questions about water pollution. First, what are the long-term trends in U.S. water quality? Second, what share of the trends is due to the Clean Water Act? Third, to what extent do Americans value clean surface waters? Finally, what is the potential of new regulatory mechanisms to decrease both ambient water pollution and abatement costs?
Synopsis:
This research investigates several questions about water pollution. First, what are long-term trends in U.S. water quality? Second, what share of the trends is due to the Clean Water Act? Third, to what extent do Americans value clean surface waters? Finally, what is the potential of new regulatory mechanisms to decrease both ambient water pollution and abatement costs?
Approach:
This analysis is compiling data on water quality, regulatory enforcement, and federal funding instituted under the Clean Water Act. It introduces new methods in environmental statistics to analyze how the Clean Water Act affects water quality. The analysis exploits idiosyncrasies in the location and timing of federal activities. The analysis also constructs a simulation to measure how redesigning water pollution regulations would affect water quality, abatement costs, and social welfare.
Expected Results:
This analysis will provide evidence on how the Clean Water Act affected surface water quality. It will also investigate how Americans value clean surface waters and thereby clarify the benefits of the Clean Water Act. Finally, it will investigate the potential benefits of new regulatory mechanisms for water pollution emissions.
Potential to Further Environmental/Human Health Protection:
Although the United States has invested tremendous levels of resources to improve surface water quality, roughly 40 percent of surface waters still violate standards for designated uses. This research will provide new evidence on the extent to which the Clean Water Act has improved water quality, on the potential benefits from improving water quality, and on potential improvements in water quality that could result from using new regulatory mechanisms.
