Abstract
Groundwater nitrate contamination is a significant environmental concern in agricultural regions of the United States. In Kansas, nitrate concentrations in some groundwater systems approach or exceed the Environmental Protection Agency (EPA) maximum contaminant level of 10 mg/L. This study analyzes nitrate concentration data from groundwater samples in western Kansas, with a focus on the High Plains aquifer, where agricultural activity is intensive. Using data analysis and regression methods, spatial patterns in nitrate distribution were identified. Results indicate that nitrate concentrations vary across sampling locations, with higher levels generally associated with regions of intensive agricultural activity. Several sites approach or exceed the EPA standard, suggesting potential risks to human health. These findings highlight the importance of continued groundwater monitoring and improved nutrient management strategies to mitigate contamination.
