Abstract Recently there has been legislation to limit the discharge of litter into the aquatic environment. The U.S. EPA Office of Water has responded by implementing pilot studies to detect changes in trends of litter in the aquatic environment associated with the implementation of legislation. A general survey design for detecting changes in trend of aquatic litter on the nation's shorelines was presented. Specific recommendations for number of survey units and frequency of sampling depend on required confidence and power as well as study-specific economic constraints. The particular model used for sample size calculation is based on normally distributed errors and efforts should be made to validate the model. With a planned survey, impacts of legislation and educational efforts in reducing aquatic litter can be evaluated.
