1. Geothermal Resources / Ground source heat pump
   Geothermal ground-source heat pump systems (GSHPs) use stable temperatures found in the upper few hundred feet of the earth's surface as a heat battery to efficiently heat and cool homes, schools, and businesses.
2. Mine Reclamation / Acid Mine Drainage
   Pyrite, or iron sulfide (FeS2), is a mineral that is commonly found within Indiana coal seams and the adjacent rock strata. When coal beds and surrounding rock units are disturbed during mining, the associated pyrite is exposed to oxygen and water, and chemical reactions produce highly mineralized acidic mine drainage (AMD).
3. Mine Reclamation / Reclamation in Indiana
   Acid mine drainage (AMD) is the cause of many environmental problems associated with abandoned mine lands. Where AMD is present, the abundance and variety of plant and animal life is greatly reduced, so that the land is susceptible to erosion and streams are subjected to siltation.
