Disclaimer
If the Current Monitoring Period Date Range reads “Monitoring Completed”, sufficient samples have been collected from the specified water system facility (WSF). If the Current Monitoring Period Date Range reads “Monitoring Partially Completed”, sufficient samples have been collected for some but not all the analytes in the group. A monitoring violation may occur if samples were not collected from the appropriate sampling point, were not analyzed by a certified laboratory, or were not reported on time. Total Coliform Rule (TCR), triggered, confirmation or repeat schedules or schedules with a daily or weekly frequency will not display this message.
