Noncommunity drinking water analytes

Noncommunity drinking water analytes

Contained on this page are a list of non-microbial analytes that are required for noncommunity water supplies under the Michigan Safe Drinking Water Act. Total coliform and E. coli also must be collected at all noncommunity supplies. See your local health department or EGLE for your unique sampling schedule.
