This map image layers displays combined risk (water shortage + water quality) for domestic wells and state small water systems. This layer is for use in the 2022 SAFER Needs Assessment. There are three key data fields available: Combined Risk: water shortage and water quality risk combined in one score (combined risk score = (water shortage risk score + water quality risk score)/2) Water Quality Risk: raw data is from the 2022 Aquifer Risk Map. Raw data is normalized into four risk bins which correspond to numeric scores (high risk = 1; medium risk = 0.25; low risk = 0, no data available = N/A). Water Shortage Risk: raw data from the Department of Water Resources Water Shortage Vulnerability Tool for self-supplied communities. Raw data is normalized into four risk bins which correspond to numeric scores (top 10% of scores = 1; top 25% of scores = 0.25; lower 75% of scores = 0; no data available = N/A). All PLSS sections also display the estimated count of domestic well locations (derived from Department of Water Resources Online System for Well Completion Reports) and the count of known state small water systems (from the Division of Drinking Water).
