What is the purpose of SW-846?

 

Test Methods for Evaluating Solid Waste, Physical/Chemical Methods, also known as (SW-846), provides a unified, up-to-date source of information on sampling and analysis related to compliance with Resource Conservation and Recovery Act (RCRA) regulations.  It brings together into one reference all sampling and testing methodologies approved by the Office of Resource Conservation and Recovery (ORCR) for use in implementing the RCRA regulatory program.  The manual provides methodologies for collecting and testing representative samples of waste and other materials to be monitored.  Aspects of sampling and testing in SW-846 include quality control, sampling plan development and implementation, analysis of inorganic and organic constituents, the estimation of intrinsic physical properties, and the appraisal of waste characteristics.

The procedures described in this manual are meant to be comprehensive and detailed, coupled with the realization that the problems encountered in sampling and analytical situations require a certain amount of flexibility.  The solutions to these problems will depend, in part, on the skill, training, and experience of the analyst.  For some situations, it is possible to use this manual in rote fashion. In other situations, it will require a combination of technical abilities, using the manual as guidance rather than in a step-by-step, word-by-word fashion.
