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.
National Lead Poisoning Prevention Week marks a time when EPA and our federal partners promote education and awareness activities that focus on lead and how to prevent its negative health effects. This year, we focus on the theme, “Lead-Free Kids for a Healthy Future.” It’s through our joint efforts that we have been able to make significant strides in reducing exposure to lead over the past several decades.
The client revived, expanded and modernized its operations in order to produce rare earth materials in high volumes and in an environmentally responsible manner. As part of the expansion, the client contracted Veolia to design and build a new water treatment plant for their state-of-the-art rare earth facility.
The water treatment plant at the client’s site was designed not only to meet low level discharge requirements for overall environmental compliance but also to meet the regional discharge levels of the Great Lakes Restoration Initiative (GLRI). This initiative included strict discharge limits of mercury at 1.3 parts per trillion.
The client is one of the largest combined electric and gas companies in the United States, servicing 1.8 million gas customers and 2.2 million electric customers in more than 300 urban, suburban and rural communities. Following a successful site visit, the Client contracted Veolia for the treatment of up to 2725m³/h (12,000 gpm) of sewage plant effluent for cooling tower make-up.
