ALTERNATIVE ONSITE TREATMENT SYSTEMS INCLUDING CONSTRUCTED WETLANDS FOR TRACE ORGANIC CONTAMINANT REMEDIATION
Trace organic contaminants (TOrCs) encompass a diverse group of chemicals not currently regulated in US waste or drinking waters which have been found to have ecotoxicological effects in aquatic ecosystems at extremely low levels. On a local scale, onsite treatment systems may have potent impacts on resources that are invaluable to residents, including surface and groundwaters. A Virginia Tech student completed a preliminary engineering report (PER) reviewing alternative treatment options to replace conventional septic systems for a small community with unusually high pharmaceutical consumption rates. Constructed wetlands were considered along with two proprietary systems: an aerobic styrene biofilter (EZ-Treat) and an aerobic treatment unit with a peat biofilter (Anua). The PER included findings from a literature review, a pilot study using real septic tank effluent from the community, and a cost analysis including capital and long term expenses. Although the wetlands exhibited excellent removal of nutrients and TOrCs, the Anua system had better removal of TOrCs and offered economic and strategical advantages over the compared options.
