December 4, 2020: The District has received the results from the Legionella re-test at Springdale Jr-Sr HIgh School.  The District replaced hardware in six locations, which were then re-tested; three still have concentrations of Legionella.  Cleaning, superheating, and running the water are the main recommendations from the testing company, with hyperchlorination of the affected areas as the next step.  At this time, the District is consulting with a plumber to discuss options and assist with the matter.  Once completed, the District will re-test these areas.
