This paper presents the findings from a contingent valuation survey designed to estimate the option price bids for the improved recreation resulting from enhanced water quality in the Pennsylvania portion of the Monongahela River. The findings are based on a survey design that used professional interviewers to conduct personal interviews determined from a representative sample of 393 households. The findings suggest that the question format affects the option price estimates and that criteria for determining the final sample of responses have an important influence on contingent valuation results.
