Nitrate Pollution in Your Drinking Water

Nitrate pollution, largely caused by human activities like industrial agriculture, is contaminating drinking water sources. Nitrates are nutrients that are essential for plant growth, but they act as a pollutant when present in excessive amounts in our groundwater, rivers, and lakes.  Sources of nitrate pollution include livestock farms, fertilizers, septic systems, and industrial wastewater. 

While it was previously linked mainly to “blue-baby syndrome,” recent studies suggest that long-term exposure to elevated nitrate levels may also increase the risk of thyroid and other cancers, including colorectal and ovarian cancer.

Research indicates that nitrate pollution in drinking water could be responsible for over 12,500 cancer cases annually in the U.S. These findings highlight the need to reevaluate existing nitrate standards to better protect public health.

To address this, improvements in agricultural practices, waste management, and environmental laws are essential. Individuals can help by testing their well water and supporting policies to reduce agricultural runoff. Raising awareness is key to ensuring cleaner, safer water for all.
