Air Quality

• Air Quality Monitoring Website – Displays DEQ’s air quality monitoring activities throughout Idaho, and provides real-time air quality data for each location.

Surface Water Quality

• DEQ’s Final 2024 Integrated Report– An interactive, map-based source of information on water quality of lakes, reservoirs, rivers, and streams in Idaho for the 2024 Integrated Report.

Groundwater Quality

• Idaho Nitrate Priority Areas (2020) – Displays groundwater quality areas where nitrate concentrations potentially degrade drinking water quality (25% of sampled wells exceed 5 milligrams per liter). The areas are evaluated and prioritized for allocating resources to develop and implement improvement strategies.
• DEQ Groundwater Quality Data – An interactive, map-based source of information on groundwater quality analytical data collected by DEQ or DEQ contractors. DEQ investigates groundwater quality in regional and local areas where contamination is known or is suspected to have occurred.

Source Water Assessment and Protection

• Source Water Assessment and Protection – Shows Idaho’s source water protection areas and potential contaminant inventory. DEQ uses source water assessment information to oversee public waters systems in Idaho and determine the likelihood that a water supply will be contaminated.
