The Ministry of Environment Tuesday completed checking 435 water treatment plants nationwide and found larva-like organisms in the filter beds of three, but said they did not enter the tap water.
Despite continued reports of larva-like organisms found in sinks and bathrooms, Seoul water authorities said Wednesday none of them are coming from the tap water. But they announced a team of experts will investigate.
Larva-like organisms have been found at seven water treatment plants nationwide, the Ministry of Environment announced Tuesday, but said that the bugs only made it into the tap water of two facilities that serve Incheon.
After larva-like organisms were spotted in tap water in Incheon earlier this month, sales of bottled water close to doubled over the past four days compared with the same period last week, at convenience stores near the area.
After larva-like organisms were spotted in tap water in Incheon earlier this month, similar discoveries were reported in Seoul, Gyeonggi and Busan, raising nationwide alarm over water safety.
