After laboratory evaluations, we presented our research results regarding the benefit of using vetiver systems to the Nong-Nea community. Additionally, we used the phenol removal rates to design three field-scale implemntations. On August 28–29, 2014, we implemented the first field-scale vetiver system, the vetiver hedgerows, along Tat Noi Creek. Devember 5, 2015, we implemented the field-scale treatment of illegally dumped wastewater at Mr. Manus’s pond. A new treatment pond was prepared with an HDPE liner to prevent the infiltration of cotnamianted water. The contaminated water was pumped from the illegal dumping pond to the HDPE pond. Vetiver grass on 45 floating bamboo platforms were used to treat the wastewater in the HDPE pond. In April or May, 2015, we plan to implement the last prototype of vetiver system, a field-scald PRVRB with engineered, extended root zone to intercept plume in shallow groundwater from an inaccessible source zone.
