To support EPA’s efforts to advance knowledge for conducting economic evaluations of environmental policies, the main objective of our proposed research is to develop and demonstrate methods for valuing the use and nonuse benefits of improving water quality in wadeable streams in urbanizing watersheds. These streams provide valuable ecosystem services and are subject to a combination of anthropogenic stressors that have led to pervasive degradation referred to as “urban stream syndrome.” Understanding how the general public perceives and values improvements in stream conditions is necessary to support EPA’s efforts to quantify the public’s willingness to pay (WTP) for water quality improvements.
