Roughly 140 local residents have registered for groundwater testing being conducted by UW Oshkosh but Door County Public Health wants more. The department wants a geographically diverse random sample that represents the wide variety of soil types in the county says Registered Sanitarian Chelsea Smies.
If a homeowner is selected for the study the test costs $20 and it includes monitoring for bacteria and nitrates. Homeowners who are not a part of the study can get testing done for $45.
