註釋We estimate the value of water quality improvements for recreational activities on and near the Brandywine Creek in Delaware. We divide water-based recreational activities into two groups: water-contact and non-water-contact. We then consider the behavioral change of the recreationists in each group when faced with water quality improvements posed in a stated preference (contingent behavior) survey. We use five common physical attributes of water quality in the contingent behavior analysis: water clarity, catch rate of fish, safety of eating fish, safety for swimming, and ecological health. The survey was constructed in such a way that each of these attributes of water quality are valued. The per trip value for water quality improvements ranged from $4 to $63 for contact use and from $4 to $29 for non-contact use depending on which and how many attributes of water quality improve. Even though we measure sizable benefits, costs are likely to exceed benefits based on preliminary cost estimates.
