The managers of a luxury condominium in Bangkok are in hot water after tap water resulted in eye infections in as many as 200 residents.

The problem began nearly four weeks ago and still has not been fully resolved, with the Bangkok Metropolitan Administration (BMA) vowing to take legal action if it isn’t fixed soon.

Health officials from Chatuchak district first learned of the problem on June 14, when reports emerged that 90 residents of the condominium had experienced eye inflammation. 

The name of the condominium in the Lat Phrao area was not given but it was reported that units there can cost 10 million baht.

Tests found no residual free chlorine in the water tanks of the condominium building. That was substandard for tap water.

Officials also banned the use of its swimming pool.

On June 25, a test found a parasite that causes eye infections in tap water from underground tanks and five condominiums. 

On June 26, BMA health officials were told that the number of eye inflammation cases in the building had reached 200.

Officials would revisit the building on Thursday. Management will face legal action from the BMA if it fails to keep water quality up to safety standards.
