Monday was a busy day at the Hillsboro water plant. A hot, windless weekend had created an algae bloom at Marion Reservoir, meaning iron and manganese levels had shot up in the town’s water supply. Water plant employees —three in total, plus Richard Fine, a retired Agco employee who helps out — learned of the bloom immediately, thanks to a buoy system that measures oxygen levels at the reservoir water intake.
