| Details: | SUMMARY: Algae Bloom in Reservoir #3 DETAILS: Gary McLauchlin called to see if they could use an algicide called GreenClean in their finished water reservoir #3. I approved the use as long as it was the GreenCleanPRO, which meets standard NSF 60 for use in potable water. I spoke to him about Cyanobacteria and e-mailed him information on testing and public health implications and advised them to determine what type of algea it was before applying the algicide. I directed him to contact Casey Lyon in the Springfield office, who is more knowledgable about the cyanobacteria. ACTION NEEDED: System to evaluate testing and/or treatment option using GreenCleanPro for algae control. Gary spoke to Casey Lyon the same day and indicated that they may do some testing before applying any algicide. | ||
