Effects of land use and geohydrology on the quality of shallow ground water in two agricultural areas in the western Lake Michigan drainages, Wisconsin

By David A. Saad

Subsequent to publication of U.S. Geological Survey Water-Resources Investigations Report 96-4292, "Effects of land use and geohydrology on the quality of shallow ground water in two agricultural areas in the western Lake Michigan drainages, Wisconsin," the following errors were found in the report.

Pages affected: 13, 14, 16, 17, 18

We apologize for any inconvenience these errors may have caused.


 

Page 13 - Table 1 "Location and characteristics of land-use study wells and springs." CFC-based recharge dates for the following wells were incorrect as originally published in Table 1. Correct values are shown to the right of the incorrect values.
