based on the experiences of the Water Quality program and past USDA water quality programs such as the Rural Clean .Water Program (RCWP), and on the findings of research in the area of technology adoption, the conditions under which voluntary, watershed-based water quality projects have the best chances for success can be outlined:
The success of some RCWP projects was limited because agriculture was not the primary source of water quality impairment (Magleby et al.
A finding of the RCWP program was that accurate definition of critical areas is a significant factor in project success (Gale et al.
In a survey of participants in the voluntary RCWP program, Hoban and Wimberley found that only 14% of the respondents felt that water pollution was a serious problem in their area, despite the fact that projects were selected on the basis of existing water quality problems (Hoban and Wimberley 1992).
One of the lessons learned from the RCWP program is that the profitability of a practice greatly enhances the probability that its use will be continued, after all assistance has ceased (Magleby et al.
Results from the RCWP and other programs suggest voluntary approaches supported by regulatory capabilities may be the most effective means of reducing pollution from agricultural sources (Gale et al.
