PFC Groundwater Contamination
Our home property in Washington Co. has our own well water. Recently, in a co-operative effort by the Minnesota Dept. of Health and the Minnesota Pollution Control Agency, our well water was tested for perfluorochemical (PFC) contamination and was determined unsafe for drinking or cooking. Perfluorooctane Sulfonate (PFOS) in our well was determined to be at 0.081 ppb. Drinking water criteria is 0.027 ppb. Perfluorooctanoic Acid (PFOA) in our well was determined to be at 0.069 ppb. Drinking water criteria is 0.035 ppb. We have been provided with bottled water for our personal consumption. We have made application to have a granular activated carbon (GAC) filter installed to treat our drinking water. Finally, my question. We have a vegetable garden which we irrigate with our well water and of course, we eat the vegetables. Should we be concerned that the vegetables we consume from our garden are contaminated with levels of PFC above and beyond a safe level? Do unsafe levels of PFC appear in asparagus, great beans, potatoes, squash, tomatoes, etc.? Should we make some attempt to install the GAC filter system so our garden irrigation water is filtered as well?
