Water Quality Test Results
June, July & August 2023

Call 264.5628 to report Water Quality or Storm Water issues

 Water test samples are gathered from the various sites every Monday and Wednesday and delivered to a private lab where they are tested for the presence of E.Coli. Testing takes 30 hours to complete at the lab. Results are usually posted by 5:00 PM the day after the sample is taken.

SINCE 2013: Water samples with E. Coli levels higher than 235 CFU/100mL indicate water that is unsafe to swim in. High E.Coli can cause intestinal discomfort (gastroenteritis). Individual site readings above 235 CFU/100 ml indicated in RED. When two or more Bayside Beach or Rossetti Nature Area readings are above 235 CFU/100 ml, the beach will be marked as unsafe (signage at the beach entrance) and retested until the readings are acceptable. The followup retesting of those town sites is indicated following each high reading.

      If you have any questions or comments, please call Brett McCreary at 264.5628
