Arsenic in Drinking Water and Bladder Cancer

Arsenic in drinking water from private wells linked to risk for bladder cancer

For over 50 years, higher mortality and incidence rates for bladder cancer have been observed in New England, compared to most parts of the United States. This population-based, case-control study of bladder cancer in New Hampshire, Vermont, and Maine sought to explain the reasons for the persistent excess of rates of bladder cancer in northern New England.

Investigators collected data on 2,600 participants via personal interview and collected biological samples (blood, buccal cells, urine, toenails, and tumor tissue), as well as drinking water samples.

They found that drinking water from private wells, particularly dug wells established during the first half of the 20th century, may have contributed to the elevated risk of bladder cancer that has been observed in Maine, New Hampshire, and Vermont. Other risk factors for bladder cancer, such as smoking and occupational exposures, did not explain the excess risk in this region.
