A map of bladder cancer mortality rates
Bladder cancer rates have been elevated in northern New England for at least 5 decades in males and females, which suggests environmental causal factors. The high proportion of private domestic wells in this region and the prevalence of arsenic in such wells led to the hypothesis that arsenic in drinking water from private wells may play a role the elevated bladder cancer rates.
