AWWA WQTC69379

This powerpoint presentation begins by presenting the following questions: how common (or rare) is wastewater (WW) effluent presence in drinking water sources (a watershed analysis); are there chemical signatures of wastewater impacts on drinking water sources (bulk effluent organic matter (EfOM) components, effluent-derived organic micropollutants); how sensitive are these chemical signatures (WW-dominated (> 50 % WW effluent), WW-impacted (10 - 50 % WW effluent), and WW-minimally-impacted (< 10 % WW effluent); and, can the problem of wastewater-impacted drinking water sources be managed from the perspective of WW-derived organics - case studies of intentional/planned (indirect) potable reuse. Includes tables, figures.
