- PFOA and PFOS have been linked to kidney and testicular cancer.
- The chemicals PFOA and PFOS have been found to cause harm at levels below what the EPA has claimed is safe.
- The EPA has decided not to regulate these chemicals, but still lists them as hazardous.
- If you are in doubt about your current water supply, using a water filtration system is recommended.
January 2019: Water Safety
The EPA has decided not to regulate two cancer causing chemicals under the Safe Drinking Water Act.
The chemicals PFOA and PFOS are linked to kidney and testicular cancer, and have been found in groundwater near military bases and chemical plants.
It is now up to consumers (anyone who drinks water) to look out for these chemicals and take steps to avoid them.
The chemicals will be listed as hazardous, but instead of holding companies like 3M or the Defense Department responsible for preventing these cancer causing chemicals from contaminating drinking water, it is now up to consumers (anyone who drinks water) to look out for these chemicals and take steps to avoid them.
If you live near a military base, or a chemical plant, I suggest you ask your city or town for test results for your local water supply. If they are not testing for these chemicals, you may want to filter your own water until you have sufficient data.
What are your options to filter drinking water?
There are several articles that address different filter needs depending on what's in your water.
At the top, and expensive end, is a Reverse Osmosis system. It will filter out organic and inorganic impurities. You can have the system installed at the source, so you can drink the water right out of your tap. They do require maintenance, usually about once a year you'll need to replace filters, and every 2-3 years you'll need to replace the RO membrane. If you notice the water pressure dropping, that may be an indication that the filters need to be replaced.
A simple carbon filter will remove PFOA which is an organic chemical. There's the ZeroWater filter that claims to remove everything, including some healthy minerals that you may want in water, but if you're concerned, it's a start, and you can always get minerals from your diet.
