PFAS detection levels vary by region and across matrices such as drinking water, wastewater, seawater, soil, etc. Drinking water is the matrix of most concern in relation to public health and many environmental agencies are trying to set safe consumption levels. Most are in the form of health-based recommended levels with no regulations in place as of Feb 2019. Currently, in most countries, designated levels of concern are in the low ppt (ng\/L) range for most PFAS compounds in drinking water. Some examples are given below.<\/p>\n\n\n\n
