This article refers to very old research papers, some goes back over 20 years. Isn't there any new findings on the effect of Nitrite/Nitrate in drinking water to cancer related cases?

Both nitrate and nitrite were tested in high dose animal bioassays and not considered carcinogenic. Both are naturally present  in many foods, including green vegetables, as well as cured meats to prevent botulinum growth. They also are cycled internally in humans from protein catabolism and produce nitrosamines . So there is no escape from mother nature. The drinking water issue is methemoglobinemia and inadequate or lack of  disinfection to prevent GI infection in infants.
