OverviewAI-generated summary

Ashley D. Pifer investigates water quality, with a focus on disinfection byproducts and residual management in drinking water distribution systems. Her research has explored methods for quantifying nitrite, mitigating natural organic matter interferences, and understanding the formation of various disinfection byproducts like chlorite, chlorate, and perchlorate under both free chlorine and chloramine conditions. Pifer has also published on the importance of operators understanding how to measure and maintain disinfection residuals. Her work includes collaborations with researchers at the University of Arkansas at Fayetteville, including Julian L. Fairey, Justin R. Chimka, Rylie N. Hickman, and Duong Duc Thien. Pifer's scholarship metrics include an h-index of 7, with 17 total publications and 323 total citations.
