Measuring and Predicting Water Quality in Recreation-Related Terms

In order to estimate the monetary benefits accruing to recreational water

users from nationwide implementation of water pollution control policies,

five major links must be captured quantitatively: (1) those translating

the policies into levels of pollutant discharges by sources; (2) those

translating the discharges into ambient environmental conditions via

natural mechanisms for transportation, dilution, and transformation of

pollutants; (3) those translating ambient changes in scientific terms, such

as dissolved oxygen, into terms readily perceived and acted upon by

recreators; (4) those governing the patterns of responses by recreators (in

terms both by intensity and type of participation) to changes in perceived

ambient environmental quality; and (5) those involved in the valuation of

the recreators * responses. This chapter focuses on the practical aspects

of quantitatively representing the essence of the first three of the above

links, which are logically prior to the participation and valuation steps.
