Description: This layer identifies areas with high, medium, or low risk of groundwater nitrate contamination, based on the 2025 GAMA Aquifer Risk Map (ARM). Risk levels are derived from publicly available groundwater quality data collected from wells (e.g., monitoring, domestic, municipal, irrigation) at depths similar to domestic drinking water wells. The dataset also includes the number of domestic and State small water system wells per area.
