chapter  2
Measuring and Predicting Water Quality in Recreation-Related Terms
Pages 34

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.
