The County Road A disposal site, located on
the Bad River Indian Reservation, Ashland County,
Wisconsin, contains papermill sludge generated by
a former mill in the City of Ashland. Since the time
of disposal (1968-1970) the site has been the subject
of investigations by the U.S. Bureau of Indian
Affairs, the U.S. Environmental Protection
Agency, and private consultants. During 1997-
1998, an investigation was conducted by the U.S.
Geological Survey, in cooperation with the U.S.
Environmental Protection Agency and the Natural
Resources Department of the Bad River Indian
Tribe, to evaluate the hydrogeology and groundwater
quality of the disposal site, particularly with
respect to the hydraulic connection between two
ponds at the site and the shallow ground-waterflow
system. Additional monitoring wells and well
points were installed, and additional hydrogeologic,
ground-water quality, and geophysical data
were collected. The data from this and previous
studies were integrated and interpreted.
