Nitrate-nitrogen data are from sampling
conducted during 1985-2004 as reported by the Wisconsin Department of Natural
Resources, the Wisconsin Department of Agriculture, Trade and Consumer Protection,
and the Central Wisconsin Groundwater Center. Data collected at other times or

F6. Figure is based on
the results of over 35,000 Wisconsin private well samples compiled by David Mechenich
at the Central Wisconsin Groundwater Center, University of Wisconsin-Stevens
Point. "Other rural" land-use category is composed of grassland, water, wetlands, barren land
and shrub land. High permeability soils are defined as having infiltration rates
greater than 6 inches per hour, while low permeability soils have infiltration
rates less than 6 inches per hour.
