Colorectal cancer risk increased by nitrates in drinking water, Danish scientists report

Bluewater describes as ‘alarming’ new findings by scientists at Aarhus University that link nitrates in drinking water to an increased risk of colon and rectal cancer. The study, published in the International Journal of Cancer, followed 2.7 million Danes between 1978 to 2011 and was based on an analysis of over 200,000 drinking water samples taken mostly from private drinking wells.
