Joel Barlow High School will reopen today after being closed Thursday and Friday due to contamination of a water storage tank with fuel oil. Superintendent Jason McKinnon says they bypassed the tanks and flushed and tested the water pipes. The State Department of Health cleared the use of the system and reviewed the test results Saturday. JHoe Barlow students will have to make up the lost days at some point in the future. Bottled water will be provided throughout the school today for students and staff even though the system is cleared for use. A preliminary investigation determined that a contractor accidentally poured about 20 gallons of fuel oil into the school’s 20-thousand gallon water-storage tank last Tuesday.
