Dawn Stewart said she’d never encountered the foul flavour of her home’s tap water until she filled up a glass a few weeks ago. “It was disgusting and I said ‘does it taste like there’s dirt in it?'” “I ran the water for a bit and it was worse — even when I’ve got soap in it, it still has that musty odour.” With no water filters in her Royal Oak home, Stewart said the water’s earthy flavour is a disincentive to drinking it. And initially, she wondered if consuming it posed a health risk.
