The United States Environmental Protection Agency has announced lifetime health advisories (HAs) and health effects support documents for Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonate (PFOS).The HAs are developed to assist federal, state, tribal and local officials, and managers of drinking water systems with protecting public health when these chemicals are found in water.

HAs are non-regulatory but rather give the best available peer reviewed science, should these chemicals be found. These fluorinated organic chemicals were used to make carpets, clothing, fabrics for furniture, paper packaging for food and other materials (e.g., cookware) that are resistant to water, grease or stains:

Studies indicate that exposure to PFOA and PFOS over certain levels may result in adverse health effects, including developmental effects to fetuses during pregnancy or to breast-fed infants (e.g., low birth weight, accelerated puberty, skeletal variations), cancer (e.g., testicular, kidney), liver effects (e.g., tissue damage), immune effects (e.g., antibody production and immunity), and other effects (e.g., cholesterol changes).
