What The Research Says

Research is an ongoing process and each study allows us to learn more about the correlation between high nitrate levels and certain health risks. We can also gain a clearer picture on how nitrate interacts with nitrosatable agrichemicals and the factor that these compounds could play in the higher rates of birth defects and pediatric cancer in Nebraska.

Below you can find statistics for nitrate testing in Nebraska wells, rates of childhood cancer and additional studies cited on this website.

Nitrate and Nitrosatable Agrichemical Testing Results in Nebraska

An evaluation of water quality data collected over the past 40 years reveals that nitrate concentrations are continuing to increase in some areas. This page shows the results of several testing studies including the type of wells tested and the percentage of those testing positive for nitrate and nitrosatable chemicals.

Cancer Rate Research

Health researchers are gaining additional insight on the potential link between nitrate contamination in drinking water and Nebraska’s high rate of pediatric cancer.  The high concentration of agrichemicals in drinking water have been linked to  adverse health risks, such as:  colorectal cancer, thyroid cancer, stomach cancer, and ovarian cancer.

Birth Defect Research

According to a recent study, birth defects, on a national scale, occur in 3.3 percent of all live births.  Nebraska exceeds the national average with 5.8 percent.  In some Nebraska counties, however, the rate of birth defects is climbing above the Nebraska average.  The counties with higher birth defects also have a greater prevalence of agrichemicals in the water.

Nitrate and Nitrosatable Agrichemicals

Nitrate alone can cause health issues but in combination with other chemicals such as atrazine that can also contaminate groundwater, the risks of developing disease lymphoma can significantly increase.

Nitrate and Other Interactions

Research is also being done into how nitrate interacts with other contaminants, such as uranium. It’s possible that nitrate can lead to secondary uranium contamination in groundwater.
