Description
Water contamination is one of the biggest threats to water supply and can have long term human health consequences. It is key to identify vulnerable regions to develop better management strategies. This project utilizes hotspot and outlier geospatial analysis to locate areas across Minnesota with elevated levels of nitrate and arsenic in well water and better understand potential factors that might be influencing this. Statistically significant hotspots and cold spots were identified with up to 99% confidence. Hotspots of nitrate were located mainly in the south-central region while hotspots of arsenic were located primarily in the western and south-central portions of the state. Land use factors should be taken into consideration and extra attention should be given to these portions of the state.
