Abstract

Chloro-s-triazines have been implicated as potential endocrine disrupting compounds in humans based on their common mode of action. Chloro-s-triazines include parent compounds such as atrazine, simazine, and cyanazine as well as a suite of their metabolites. As a result, future drinking water regulations in the United States may be based on total chloro-s-triazine concentrations in addition to the existing regulations based on individual parent herbicides. This paper reviews the effectiveness of conventional drinking water treatment processes including powdered activated carbon, granular activated carbon, ozone, biofiltration, and membranes. In general, it is apparent that chloro-s-triazine herbicides and their metabolites should be readily controlled using these conventional technologies.
