Description:
Global economic development and an increasing population have dramatically increased demand for water resources. Anthropogenic chemicals released from waste water treatment plants (WWTP), as well as industrial and agricultural operations, often negatively affect the quality of receiving waters and produce adverse impacts on associated ecosystems. Moreover, these same receiving waters often serve as source waters that, once properly treated, are destined for public consumption. This use of treated wastewater (after mixing with receiving waters) has been referred to as de facto (unplanned) potable reuse. Cell culture-based metabolomics was used in a proof-of-concept study to investigate the biological effects of environmental contaminants as they traveled from a WWTP discharge to a drinking water treatment plant (DWTP) intake in a de facto reuse cycle. Zebrafish liver (ZFL) cells were exposed to water samples collected along a surface-water flowpath, including WWTP, its upstream and downstream sites, the drinking water intake, and treated drinking water.
