Since pesticides enter the aquatic environment in runoff from agricultural areas as well as from point sources, control must be based on a multiphased approach:

1. Controlled application in minimum quantities over areas where specifically needed

2. Degradation in soil and watercourses

3. Removal at plants producing potable water

4. Treatment of wastes from pesticide handling facilities and sewered areas

The various mechanisms for removing pesticides entering the environment are discussed in this section as outlined in Table 8.2.4, and the chemical structures of the pesticides are shown in Figure 8.2.11.
