The objectives of this program were to evaluate the effectiveness of the National Pesticide Monitoring Program (NPMP), identify program strengths and weaknesses, and recommend actions necessary to increase program capability. Specific tasks accomplished included: (1) Compilation of NPMP Data - Available data were grouped by relevant parameters such as environmental component monitored, frequency of collection, number and location of samples taken, chemicals monitored and means of monitoring; (2) Effectiveness of NPMP System - The available data were assessed with respect to drawing statistical inferences on trends in national pesticide residue levels, and data limitation problems identified; (3) Survey State Monitoring Activities - The emphasis of this task was on the determination of data availability to augment a national system; and (4) Recommendations - This task considered implications of project findings with respect to policy options available to Government for improving pesticide monitoring capability.
