Name: Nitrate Risk in 2025 ARM Water Quality Well Data

Display Field: gm_well_id

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: This layer shows the point locations of wells (e.g. monitoring, domestic, irrigation, municipal) that provided nitrate concentration data used to calculate water quality risk estimates for the GAMA 2025 Aquifer Risk Map (ARM). Risk levels for GAMA ARM source data were reassessed based on nitrate concentrations and categorized as high, medium, or low for these wells.
