| Details: | SUMMARY: Occasional IFE readings to replace CFE compliance readings DETAILS: Twice per year Lake Oswego will report the highest IFE reading instead of their CFE reading for 1-2 days on their SWTR reports. They will make a note of it on the report when it occurs. Lake Oswego has two lime feed systems. When they bring down their primary lime feeder, they employ the backup feeding system. The backup feeder dramatically affects the CFE readings, incorrectly indicating high turbidity break-through. |
