The health authority says routine water supply tests at Kelly Creek Community School have shown safe levels so far. Because the male was found early, he says health officials have rated the risk to students and staff as too low. Arsenic is a natural element found in rocks and is commonly found in groundwater in the Powell River and the Sunshine Coast, so the authorities say regular monitoring of well water is essential. “Tests for water quality and pollutants are important safeguards and should be scheduled regularly,” the authority said in a statement. Vancouver Coastal reminds those who own or operate private water systems to perform regular maintenance and testing. The school staff and students will be provided with bottled water when they return from spring break on Monday until maintenance of the water treatment system is completed.
