About 355,000 million gallons per day of water was withdrawn for use in the United States during 2010, a decline of 13 percent from 2005 and a substantial change from the level of about 400,000 reported from 1985 to 2005.
We estimated mean technically-recoverable undiscovered continuous and conventional resources that total 495 million barrels of oil, 27.5 trillion cubic feet of natural gas, and 410 million barrels of natural gas liquids in this area.
Water quality is important here because this reservoir is the primary supply for Wichita, Kansas. Due to low streamflow during the monitoring period, we expect suspended sediment and phosphorus to be more variable in the future.
We estimated mean volumes of undiscovered, technically recoverable resources of 463ï¿½ million barrels of oil, 11.2 trillion cubic feet of gas, and 35 million barrels of natural gas liquids in this area using a geology-based assessment methodology.
