Due to the problem of water outages at Terminal 2 of Haneda Airport Domestic Terminal for three days, “chloride ions”, about 30 times the standard, were detected in the water supply of the “washing machine” of the passenger aircraft where salt was detected. I understand that.

On the 6th of this month, salt was detected in the water tank at the second terminal of Haneda Airport domestic terminal and the water at the washing machine, so the second terminal was shut down for three days, and the cause is being investigated.

Previous surveys by the Ministry of Land, Infrastructure, Transport and Tourism found that approximately 5.7 grams of “chloride ions” were detected per liter from the water supply at the washing machine of passenger aircraft where salt was detected.

“Chloride ion” is a measure of salinity, and the water supply law stipulates that the concentration of chloride ion is 200 milligrams per liter or less, and what is detected this time is approximately 30 times the standard. about it.

The Ministry of Land, Infrastructure, Transport and Tourism will set up a third-party committee with people from the airport and experts this month to promote the elucidation of where it came from.
