Interactive Mapping & GIS Data
A Geographic Information System, or GIS, is a computer-based approach to collecting, storing, and analyzing data that have spatial characteristics. The spatial locations in a GIS are defined by X,Y coordinates such as latitude and longitude. Spatial locations can show where the features are located and also define the shape of the feature. The interactive mapping applications below provide a relatively easy way to view GIS data in a web browser interface.
Air Quality Monitoring Website
An interactive, map-based source of information on DEQ's air quality monitoring activities throughout Idaho. Allows download of real-time air quality data in each location.
For assistance, contact Steve Miller at (208) 373-0432.
Surface Water Quality
DEQ's 2012 §305(b) Integrated Report (powered by ArcGIS Server)
An interactive, map-based source of information on water quality of lakes, reservoirs, rivers, and streams in Idaho. Idaho’s 2012 Integrated Report was submitted to EPA for review on January 28, 2014, and approved by EPA on July 11, 2014.
DEQ's 2010 §305(b) Integrated Report (powered by ArcGIS Server)
The 2010 Integrated Report has been superseded by the approved 2012 Integrated Report.
For mapping assistance, contact Jim Szpara (208) 373-0485.
Ground Water Quality
Idaho Nitrate Priority Areas (2014) (powered by ArcGIS Server)
An interactive map-based source of information on ground water 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 Ground Water Quality Data
An interactive, map-based source of information on ground water quality analytical data collected by DEQ or DEQ contractors. DEQ investigates ground water 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 (powered by ArcGIS Server)
An interactive map-based source of information on Idaho’s source water protection areas and potential contaminant inventory. The information acquired from source water assessments assists DEQ in overseeing public waters systems in Idaho and determining the likelihood that a water supply will become contaminated.
