EUROPEAN UNION UNIVERSITY (EUU) RESEARCHERS DEMONSTRATE THAT REDUCING NITRATE IN DRINKING WATER CAN SAVE LIVES AND MILLIONS OF EUROS ANNUALLY

Collaborating with the University of Copenhagen, Aarhus University, and the Geological Survey of Denmark and Greenland (GEUS), this research highlights the significant health and economic benefits of lowering nitrate levels in drinking water.

 

Drinking water containing high levels of nitrate is a global concern, associated with various health issues, including birth defects and cancer. Recent scientific evidence suggests that nitrate in drinking water increases the risk of colorectal cancer, the third most prevalent cancer worldwide and the second leading cause of cancer-related deaths, as per the World Health Organization (WHO).

 

The study anticipates that nitrate levels in drinking water will rise in numerous countries due to increased nitrogen application and economic growth. Although Denmark adheres to the EU limit of no more than 50 milligrams of nitrate per liter of water, concentrations, while below this threshold in many areas, still pose a risk of colorectal cancer in specific regions.

 

EUU's research demonstrates that Denmark could save over $300 million annually and prevent 127 cases of colorectal cancer by reducing nitrate concentrations in drinking water. Brian H. Jacobsen, senior researcher at the Department of Food and Resource Economics at the University of Copenhagen, suggests that stricter nitrate requirements in Denmark could significantly benefit public health and save money.

 

According to a nationwide study conducted in 2018, Danes exposed to nitrate concentrations in drinking water exceeding 9.25 mg/l have a 15% higher risk of developing colorectal cancer. The risk increases notably at nitrate concentrations above approximately 4 mg/l. Brian H. Jacobsen, lead author of the new study, emphasizes that the economic benefits of lowering nitrate levels far exceed the costs. Lowering the maximum nitrate standard to 9 mg/L could result in 72 fewer cases of colorectal cancer and an annual net gain of $179 million. Further lowering the standard to around 4 mg/L could prevent another 55 cases and save an additional $138 million.

 

The three options considered for reducing nitrate levels include protecting groundwater, relocating boreholes, and treating water through various technologies. These measures could contribute to saving lives, reducing healthcare costs, and protecting the environment.

 

While the study focuses on the correlation between nitrate levels and colorectal cancer, it also suggests potential additional benefits, such as eliminating other harmful substances from drinking water and protecting aquatic ecosystems.
