Assistance Type: MONITORING
Reasons: Cyanotoxins
 
Details: Total microcystins were detected at 0.28 ug/L in Wilsonville's routine every-two-week raw water sample collected Monday 7/1/24. As a result, monitoring of the raw water has been increased to weekly. An entry point (finished water) sample must be collected within 1 business day and entry point monitoring continue weekly going forward. Operator informed of schedule change this date will collect and freeze a sample Friday 7/5/24 and ship the finished water sample Monday 7/8/24 along with the 7/8/24 raw & finished samples. Update 8/16/24: two consecutive raw water samples are below the trigger levels & two consecutive finished water samples are non-detect so Wilsonville will stop finished water monitoring and return to every-2-week raw water monitoring only starting Monday 8/26/24.
