Abstract

Removal of potential carcinogens and toxicants by a direct wastewater reclamation system and an indirect wastewater reuse system was evaluated by means of a sensitive golden hamster cell transformation assay. Representative water samples from various stages of both the direct and the indirect reuse systems were introduced to the hamster cells and changes in the rate and pattern of cell growth were observed. Both systems proved to be highly effective in their removal of potential carcinogens and toxicants and there is no indication that the slight toxic and transforming activity detected in their final water may constitute a health hazard.
