Full Description

This paper reports on the findings of a recent AWWA Research Foundation project that was undertaken to determine if activated carbons used in water treatment could become characterized as hazardous waste. Concern regarding this type of characterization is based on an understanding that activated carbons are used in water treatment because they adsorb, and so accumulate various contaminants from source waters. These same contaminants are addressed by solid waste regulations. The question examined by this research was whether sufficient levels of regulated contaminants could be accumulated by these carbons that the material would subsequently be classified as a hazardous solid waste. As many utilities are considering the use of some type of carbon in order to help them meet water quality standards, it is important to consider the cost of this entire treatment system--including the cost of disposal of the spent carbon. If the spent carbon is classified as hazardous, then the cost to dispose of it could increase dramatically.
