1-3. What is the purpose of grouping the different wastes according to characteristics (e.g.,
toxic) in classification lists? What are some of the problems with coding systems such as these?
Grouping different wastes in inclusive classification lists according to their characteristics enables the
government regulatory agencies to keep track of wastes which are hazardous. Once on a list, the waste is
then regulated as a hazardous waste by the government. However, problems with this system arrive due to
the limitations in having a listing which basically disregard the differences among wastes, including
degree of hazard. Once considered hazardous, each waste in that classification is covered by the same
regulatory procedures. Also, when coding a waste, the classification system doesn't consider the
concentration of the constituents or other important characteristics of the particular waste. This
information is imperative when determining the ability to treat the waste or determining the fate of the
waste if released.
