Instructions and Notes | |
|
1) If no prior sample schedules appear, then no prior schedules exist within the database. |
|
2) Schedules for Oregon very small systems might not appear. If the system is active, samples must be collected for the presence of coliform bacteria once per month or once per quarter depending on water type, seasonal operating cycle, or previous sampling results. |
|
3) If a sample tests positive for total coliform or E. coli, a minimum of 3 repeat samples must be collected. At water systems where quarterly monitoring takes place, 3 routine samples must be collected the month following one in which a routine sample tested positive for the presence of total coliform or E. coli. |
|
Any time a sample tests positive for the presence of coliform bacteria, the system's operator should contact their regulator. For this water system, that is: Joel Ferguson/Julie Hamilton, (503) 742-5367. |
