Private Wells In 3 Counties Contaminated

The Wisconsin Geological and Natural History Survey reports its testing of groundwater samples from 301 private wells found unsafe contamination levels.  Scientists found nitrate and coliform bacteria.  The report released this week found 42 percent of those wells were considered to be unsafe.  It still isn’t known what caused the contamination in the wells located in Grant, Iowa and Lafayette counties.  The second set of samples will be taken this spring.
