Rozell said that the recycling of fracking ,fluid, is helping to reduce the amount of water produced by each natural gas well, but the ,fluid, can usually only be reused once. Use of injection wells - sending the ,flowback, water back thousands of feet underground away from aquifers - has been common in more developed shale formations in the South and West.
