PFOA Services

C.T. Male Associates has worked on numerous PFOA related investigation and treatment projects in New York, Vermont, and New Hampshire and has become an expert in this field. Our work includes surface water, groundwater and soil investigations and sampling; design of remedial solutions; design and construction of municipal and residential water treatment systems; and continual work with Local, State and Federal governments and regulatory officials.

What is Perfluorooctanoic Acid?

Perfluorooctanoic acid (PFOA) is a synthetic chemical compound and is among the group of chemicals commonly referred to as per-and polyfluoroalkyl substances (PFASs). Chemicals within this group are classified as “emerging contaminants” which means there is a perceived, potential, or real threat to human health or the environment and there is a lack of published health standards. The potential threat to human health exists given the possibility of exposure to PFASs from everyday items and the ability of PFASs to bioaccumulate, leading to the potential for biomagnification. PFASs were or are still used in the manufacturing processes and as ingredients of commercial and residential products of everyday items such as non-stick pan coatings, waterproof/repellent clothing, batteries, firefighting foam, waxes (car and ski) and sprays that repel stains from fabrics and carpeting.

PTFE (Polytetrafluoroethylene) is the most prevalent PFAS. PTFE is a synthetic resin and widely used in an array of commercial products due to its chemical properties: hydrophobic, resistant to high heat, low friction coefficient. PTFE is most commonly found in oil and greases, electrical wiring, sealant tapes, and non-stick coatings.

PFOA is a long-chain perfluoroalkyl carboxylic acid. This means a long chain of carbon atoms surrounded by fluorine atoms with a carboxyl group on the end of the molecule. PFOA exists as both linear and branched isomers.

linear and branched chains of PFOAs
These chemicals do not hydrolyze, photolyze or biodegrade under typical environmental conditions and are extremely persistent in the environment. They are readily absorbed after oral exposure and accumulate primarily in the serum, kidney and liver. As a result, screening levels for PFOS and PFOA have been developed by the EPA and state agencies.

PFOA Investigation and Treatment Services

C.T. Male Associates works with businesses on PFOA Investigation and treatment. As an expert in the field, we have developed strict field sampling plans targeting soil horizons to determine where PFASs may absorb and develop the best remedial measures to employ. The field sampling plan also has strict quality control requirements necessitating all field equipment that may contact sample media be PFAS free. This is achieved by obtaining laboratory results of the equipment before it is brought to the project site, compiling a list of acceptable materials, and maintaining brand consistency with disposable materials.
