Abstract: The objective of the proposed research is to validate newly developed, chemically-based, fecal source and age indicators in local watersheds, and compare their performance to previously established qPCR analyses considered to be the current gold-standards for microbial source tracking. The nature of the proposed research will include both field surveys and laboratory activities. The scope of the research spreads across space and time as we plan to survey several sites in local watersheds and wastewater treatment plants (WWTPs) during dry and wet seasons, which occur in spring and late summer respectively. Influent and effluent sites at West Hickman WWTP and Town Branch WWTP will be sampled to document the concentrations of acetaminophen and Sucralose for comparison with what may be found in adjacent watersheds that receive sewage leaks and overflows. Samples at the treatment facilities will be analyzed and the results used to compare if the acetaminophen to Sucralose (A/S) ratio in raw sewage is constant over time, and across different facilities.
