Turbidity is measured continuously at South Fork Dam, and as the water enters the system. Entering the system, turbidity climbed from less than 1 NTU at midnight, to about 5 NTU this morning.
The City’s Waterworks Operating Permit requires the City to notify the Drinking Water Officer when turbidity averages 5 NTU for 12 hours. This threshold has not been met.
As a result of this week's storm, a total of 87 mm of rain has fallen in Nanaimo over the last two days. This is considered a two-year return period storm.
