To maximize benefits while minimizing complications, the use of casts and splints is generally limited to the short term. Excessive immobilization from continuous use of a cast or splint can lead to chronic pain, joint stiffness, muscle atrophy, or more severe complications (e.g., complex regional pain syndrome).
Energy Department: Fracking doesnât contaminate groundwater. In this March 29, 2013 photo, technicians inside a trailer direct the pressure and mix of water and chemicals pumped into an Encana Oil & Gas (USA) Inc. well during hydraulic fracturing, outside Rifle, in western Colorado.
Fracking also releases  produced water  from underground that also rises to the surface, and can be anywhere from two to 200 times as much water, depending on the oil/gas/water concentrations in the shale formation.
