Suspect screening and prioritization of chemicals of concern (COCs) in a forest-water reuse system watershed

Science of The Total Environment, 694, 133378.

By: M. Hedgespeth n, N. Gibson n, J. McCord*, M. Strynar*, D. Shea n & E. Nichols n

author keywords: HRMS; Suspect screening; Wastewater; Forest; Exposome
TL;DR: Assessing chemical features in ground- and surface waters from a watershed where secondary-treated wastewater is irrigated onto 900 ha of temperate forest offers a more holistic view of chemicals that contribute to the exposome, suggesting that though wastewater may be a source of chemicals to ground and surface Waters on-site, dissipation of wastewater-derived features likely occurs with limited off-site surface water export by the forested land treatment system.
