The site name is used to identify a particular facility or area
of interest to the Minnesota Pollution Control Agency (MPCA).
This name is used by MPCA staff to group wells into a particular

A data system developed by the Minnesota
Geological Survey and the Minnesota Department of Health for
storing, retrieving and editing well water information. The CWI
database contains basic information such as location, depth and
water level for wells drilled in Minnesota. It also contains
construction and geological information from the well record
(well log) for many wells.

The maximum level at which a contaminant can exist in drinking
water without having an adverse effect on human health.
