A look inside the Ground Water Contamination site a Secondwind technician installed recently for the treatment of PFOS, otherwise known as Perfluorooctane Sulfonate.

PFOS is an emerging contaminant of concern, currently unregulated but there are advisory levels. Historically it has been used in firefighting foam at fire training areas, it creates that impermeable layer which “suffocates” the fire. PFOS is extremely persistent in the environment and resistant to typical environmental degradation processes. As a result, it is widely distributed across the higher trophic levels and found in soil, air and groundwater at sites across the United States. The toxicity and mobility potential of PFOS poses potential adverse effects for the environment and human health.

Here’s more information from the Environmental Protection Agency on PFOS.
