This Minnesota Pollution Control Agency
(MPCA) and Minnesota Department of
Health (MDH) fact sheet includes some site
history information and describes testing of
ground water, including private wells, for
perfluorooctanoic acid (PFOA) near the
former Washington County Landfill.
Additionally, this fact sheet discusses
PFOA, and explains why state agencies
tested for it, how the testing was done and
what was found. Finally, the fact sheet tells
citizens where they can get more
information.
Public Health Assessment: Perfluorochemical Contamination in Lake Elmo and Oakdale, Washington County, Minnesota
MDH, in cooperation with the Agency for Toxic Substances and Disease Registry (ATSDR), prepared the above Public Health Assessment (PHA) on perfluorochemical contamination in Lake Elmo and Oakdale, Minnesota.
Perfluorochemical (PFC)-containing wastes were disposed of by the 3M Company at the 3M-Oakdale Disposal Site in Oakdale and the former Washington County Landfill in Lake Elmo, Minnesota. PFCs were released from the two sites resulting in contamination of groundwater and nearby drinking water wells. The PHA is an evaluation of the potential public health concerns associated with the PFC contamination.
