OSAKA (Kyodo) — Water shows at the World Exposition in Osaka will resume on Friday, after a monthlong suspension due to the detection of high levels of legionella bacteria in the venue’s seawater.
Expo organizers said Thursday they have decided to restart the shows after taking measures to improve water quality including sanitization. Following an examination, the level of legionella in water from the Water Plaza, a large seawater reservoir, was confirmed to be below the allowable limit under their guidelines.
According to the organizers, steps taken included adding chlorine to sanitize the water and increasing circulation of seawater by running eight pumps around the area.
Water testing last month revealed the level of bacteria to be 20 times higher than the limit, prompting the shows to be canceled from June 4.
