Impact/Purpose:
Although the herbicide atrazine has been reported to not react measurably with free chlorine during drinking water treatment, this work demonstrates that, at contact times consistent with drinking water distribution system residence times, a transformation of atrazine can be observed. Some transformation products observed through the use of high performance liquid chromatography-electrospray mass spectrometry are consistent with the formation of N-chloro-atrazine. The amount of transformation is shown to be largely related to the amount of applied chlorine, pH, and reaction time. This paper further explores the implications of the transformation on the accurate determination of atrazine in drinking waters.
