PFAS Are Ubiquitous in Our Homes and Our Environment
Several recent legislative and regulatory efforts across the US to address PFAS have focused on limiting levels in drinking water. However, there has been relatively little conversation about the
presence of these chemicals in our everyday lives.
In several studies, the mean and median concentration of PFOA in household dust in the United States was found to be between roughly 10,000 and 50,000 parts per trillion (ppt)3. This means there is significantly more PFAS in the ambient dust in the average home than the levels currently being discussed as thresholds for drinking water. Not only are PFAS part of the air we breathe and the products we use, but they have also been found in the food we eat.
In other words, there are numerous human exposure pathways for PFAS beyond drinking water.
