Billions of liters of wastewater are treated every year in wastewater treatment plants around the world. This wastewater, both industrial and municipal, can contain various pollutants depending on the source. Wastewater may contain soap, waste products, food scraps, human waste, oils, and in some cases, metals. The main goal of wastewater treatment is to preserve the environment and keep the pollutants out of rivers and oceans.
In the fall of 2015, a small village on the border of Vermont in New York State, tested positive for Perfluorinated Compounds (PFCs), specifically Perfluorooctanoic Acid (PFOA), in the municipal drinking water. The influent levels of PFOA in the water were above 600 ng/L, and thus considered harmful to village residents. Realizing that PFOA was on the U.S. EPA Contaminant Candidate List, the Village solicited the services of engineering firm CT Male Associates to investigate treatment options and provide a treatment system.
