Deeside Mineral Water helped slow the spread of colon cancer as well as killng some liver, cervical and skin cancer cells, according to a report from Maribor University in Slovenia.

The ten-person family firm, which has been going for a decade, is looking forward to a sales boost from the findings.

Managing director Martin Simpson told The Times:

"When we get press coverage there is always an increase in sales. People read about it, they're interested, they try the water, they feel better, they stick with it."
