Footnotes

*Geometric mean was not calculated because the chemical was found in less than 65% of the study group.
*Geometric mean was not calculated because the chemical was found in less than 65% of the study group
**LOD changed during the time that samples were analyzed for this project.
# As of March 2013, PFBuS is no longer measured due to instrumental background interference.
