CON:S.UMER CONFIDENCE REPORT <br />We sample. for some contaminants less than once a'yea r because -their levels in water are not expected to <br />change from year to year. If we found any of these contaminants the last tirne we sampled for them, we <br />included them in the tables below with the detection date. <br />We may have done additional monitoring for contaminants that are not included in the Safe Drinking <br />Water Act. To.request a copy of these results, call the Minnesota Department of Health at 651-20.1-4700 <br />or 1-800-818-9318 between 8:00 a.m. and 4:30 p.m., Monday through Friday, <br />Some contaminants .are monitored regularly throughout the year, and roliin&(or moving) annual averages <br />are. used to manage compliance. Because of this averaging, there are tim sWh <br />g the Range of Detected <br />Test Results for the calendar year is lower than the Highest Average ar ;Highest Sfig[ Test Result, because <br />it occurred in the previous calendar year. ``_ ` `t- <br />Definitions <br />• AL (Action Level): The concentration of a`contarninai ; ``which, if <br />other requirements Which a water system must fa la iir, <br />d EPA: Environmental Protection Agency <br />z <br />• MCL (Maximum contaminant level): The highest leveE`'o cant <br />Water.
