Trace organic chemicals are potentially harmful to human and ecosystem health. They frequently occur in wastewater from septic systems and can be found in concentrations orders of magnitude higher than typical concentrations reported in centralized treatment plant wastewater. This 7-page fact sheet identifies common trace organic chemicals of concern in wastewater and their sources, and summarizes current research on the fate and transport of these chemicals in septic systems.
