Many households in Southwest Virginia rely on septic systems for wastewater treatment (Galbraith et al., 2015). These systems are often aging, unmaintained, or failing, resulting in groundwater contamination (Thompson & Litton, 2005). The karst topography of the region puts groundwater at risk of being more easily contaminated by septic infiltration (Panno et al., 2020). Constructed wetlands (CWs) are an alternative to the septic system, and may offer a more sustainable, affordable, and effective wastewater treatment method.
