PFOS-PFOA Treatment

We Treat PFAS in situ with injection technologies along with groundwater and Municipal Supply and POE Systems for households and dewatering sites

WHY YOU SHOULD BE WORRIED

Perfluorinated Chemicals (PFAS) including Perfluorooctane sulfonate (PFOS) and Perfluorooctanoic acid (PFOA) or Perfluorooctanesulfonic Acid refer to a group of synthetic compounds containing thousands of chemicals formed from fluorinated PFOA and PFOS and are fluorinated organic chemicals that are part of a larger group of chemicals referred to as perfluoroalkyl substances (PFASs).

PFOA and PFOS have been the most extensively produced and studied of these chemicals. They have been used to make carpets, clothing, fabrics for furniture, paper packaging for food and other materials (e.g., cookware) that are resistant to water, grease or stains. They are also used for firefighting at airfields and in a number of industrial processes. Scientists have found PFOA and PFOS in the blood of nearly all the people they tested. Drinking water is a source in the small percentage of communities where these chemicals have contaminated water supplies close to airfield at which they were used for firefighting.

PFAS, PFOA & PFOS DRINKING WATER HEALTH ADVISORIES

To provide Canadians, including the most sensitive populations, with a margin of protection from a lifetime of exposure to PFOA and PFOS from drinking water, EPA established the health advisory levels at 70 parts per trillion. When both PFOA and PFOS are found in drinking water, the combined concentrations of PFOA and PFOS should be compared with the 70 parts per trillion health advisory level. This health advisory level offers a margin of protection for everyone throughout their life from adverse health effects resulting from exposure to PFOA and PFOS in drinking water.

Suspected Effects of Long Term Exposure
  • affects the developing fetus and child, including possible changes in growth, learning, and behaviour.
  • decrease fertility and interfere with the body’s natural hormones,
  • increase cholesterol,
  • affect the immune system, and
  • increase cancer risk.
ION EXCHANGE FOR TREATMENT FOR PFAS IN WATER

Exchange of ions between a solid substance (resin) and an aqueous solution. We are having the best treatment results with the Purofine PFA694E. A proprietary resin with the dual removal mechanism of ion exchange and adsorption technology built into each bead for maximum uptake of PFASs. Water treated with this resin will consistently achieve non-detectable levels of both short- and long chain PFASs—including PFOA and PFOS—that are well below the current Health Advisory recommendations set by the US Environmental Protection Agency.

MOBILE PFAS TREATMENT
We now has three systems available for emergency response, dewatering sites, pilot testing and storage tank cleaning near hangers. We have two 125 gpm systems and a 25 gpm system available. We recently treated 450,000 gallons with 45,000 PPT PFAS to non-detect in four days.
WHY USE LANDSHARK ENVIRONMENTAL
Our company’s Engineers have been performing Groundwater Remediation and Wastewater Treatment since 1985.  We have worked on four continents.  Use our expertise to solve your most difficult problems. We are already working on Multiple sites treating up to 1000 gpm water treated with PFOS and PFOA.  Another  site we have is a 1,000,000 PPT  PFOS-PFOA treatment system.  We are currently working on sites with the Air Force, Navy and the Marines on 9 sites.
