Option Values, Preservation Values and Recreational Benefits of Improved Water Quality: A Case Study of the South Platte River Basin, Colorado

This is believed to be the first empirical test of the concept of option value for any non-market good. Application of the bidding game technique was successful in meeting the primary study objective of measuring the option value of improved water quality. Also included are improved estimates of the benefits to recreational users of enhanced water quality, the existence value of a natural ecosystem, and the value of its bequest to future generations. The relationship between the value of improved water quality and several socioeconomic variables was tested with regression and other statistical procedures. The report is based on direct interviews with 202 residents of Denver and Fort Collins located in the South Platte River Basin, Colorado. Interviewees responded to the survey within the context of improving the quality of water degraded by heavy metals from post mining activities and preventing future degradation from such sources.
