Core Tip
Core Tip: The goal of this study was to investigate the association between colorectal cancer (CRC) incidence and chemicals commonly found in well water. The most important finding from this ecologic study is that iron in well water is significantly associated with CRC incidence across 16 counties in the state of North Dakota. These findings are broadly consistent with epidemiologic and experimental studies on the effects of iron in CRC carcinogenesis. Exploration into the implications of excess iron exposure and colorectal carcinogenesis may facilitate preventive interventions in rural and agricultural areas that rely heavily on well water as a drinking water source.
