On the day we visit Jeneyah McDonald, she has five pallets' worth of bottled water in a corner of her kitchen.
"Oh, that's low," she says.
McDonald buys more every week for cooking, drinking and brushing teeth. She also has a filter on her tap. She checks the light to see it remains green.
"I try and keep a clear glass by the sink so I can fill it up to see with some paper behind it," she says. "I mean, who else is doing that?"
