#MapOfTheDay! Today the Critical Issues Program (@AGI_GeoIssues) shared an interactive map of geothermal resources and infrastructure from the Illinois State Geological Survey (@ILGeoSurvey), which you can find at http://bit.ly/1H4eAg6. If you're interested in learning more about oil and gas, check out our Oil and Gas Basics. We also encourage you to check out our webinar, Making Produced Water More Effective, which discusses an inevitable by-product of oil and gas development.
