These days, perfluorinated sulfonate (PFOS) is an emerging drinking water contaminant that environmental authorities around the world are working to treat and eliminate.
If you're concerned with the purity of drinking water you're using for an agricultural operation, you should be aware of the threats posed by PFOS contamination.
The following are six things you need to know about PFOS and your water supply:
Perfluorinated sulfonate is a manmade compound that is not naturally found in the environment.
Perfluorinated sulfonate compounds do not exist in nature and were produced in industry for a variety of purposes. They were developed for use in stain repellents, fabric protectors, fire-fighting foams, textile impregnation agents, and more.
PFOS is already found widely in the blood of North Americans and foreign populations as well.
Exposure to PFOS is by now widespread, but Canadians can at least be comforted by the fact that their blood contains relatively low levels of PFOS in comparison to populations from other countries. Efforts in recent years made by the Canadian government and foreign governments seem to be helping to rein in PFOS exposure.
PFOS has been linked to a wide variety of health concerns in humans.
Scientific studies have indicated that PFOS exposure through drinking water entails numerous health threats to human populations. PFOS can aggravate cholesterol problems, raise the risk of preeclampsia in pregnant woman, and alter thyroid levels.
PFOS has further been show to cause severe health problems in animal studies.
More extensive research has been done on the effects of PFOS in biological systems through animal studies. Animal studies have shown that PFOS exposure can lead to the development of cancer and increase neonatal mortality.
To address the problems posed by PFOS, the government of Canada placed a ban on PFOS production in 2008.
Since 2008, the production of PFOS has been banned by the Canadian government with the Perfluorooctane Sulfonate Virtual Elimination Act. Canada now neither manufacturers nor exports the substance in any form.
Possible means of filtering PFOS out of drinking water include membrane filtration, anion exchange, and granular activated carbon.
Unfortunately, the unique makeup of fluorine-carbon bonds that create PFOS can make these compounds difficult to filter out of water supplies through traditional treatment practices.
However, it is possible to remove PFOS from water through membrane filtration, anion exchange, and granular activated carbon. Filtration techniques such as direct oxidation, vapor extraction, and biodegradation are generally ineffective against PFOS contamination.
