Description:
Experiments were performed in the EPA research house to determine the level of perfluorocarboxylic acids (PFCAs) in carpets that had been treated with one of two commercial carpet-care liquids. The ability of household or commercial carpet cleaning machines using hot water or steam extraction, with and without detergents, was also studied to determine if the removal of 15 PFCAs from treated carpeting using these methods was a viable way of controlling PFCA exposure from carpeting. Both household and commercial carpet care machines were able to reduce PFCA levels in carpets 20-50%; the additional of a detergent resulted in further removal of up to 75% reduction in total PFCAs after three rounds of cleaning.
