SINGAPORE – Singapore has ramped up local production of water to meet demand after some water from Malaysia had to be “isolated” following reports from some households here about an unusual scent of pandan in boiled tap water.

The cause of the scent is an organic compound known as tetrahydrofuran (THF), which is commonly used as a solvent in industries.

National water agency PUB said its investigations have traced the source of the issue to water imported from Malaysia.
