Salty tap water in Bangkok

Currently, the Samlae tap-water production facility in Pathum Thani's Muang district was facing a saltwater intrusion as Chao Phraya River's levels have dropped due to the drought and are too low to keep out sea water when the Gulf of Thailand is at high tide. The Metropolitan Waterworks Authority therefore allayed fears of salty tap water in Bangkok and its vicinity by insisting that a small amount of salt will do no harm, though health experts urged people with kidney disorders to be cautious.
