Date of last analysis: 6/25/08

Monitoring frequency: every 3 years

Results and MCL are in parts per million (milligrams per liter).

MCL: Maximum contaminant level, the highest level of a contaminant that is allowed in drinking water.

ND: No detect of the substance

Samples are analyzed by the Department of Natural Resources' (DNR) laboratory or by a certified laboratory under contract to DNR.
