Practices for Sampling Solid Wastes from Point Discharges and Impoundments

Abstract

Practices for sampling solid wastes from point discharges and impoundments are being developed for ASTM Committee D-34 on Waste Disposal and will provide guidance for obtaining representative samples of solid wastes from point discharges and surface impoundments. The sampling guidelines outline safety procedures, design considerations, sampling equipment, and sampling procedures. Proper design is a key component of any waste sampling program and is emphasized in these practices. The frequency of sampling or the spatial distribution of samples required to obtain a descriptive sample depends on the variability of the waste composition and the precision of waste analysis required. Given the waste variability and precision requirements, the number of samples necessary can be calculated using fundamental statistical concepts.
