National Water-Quality Assessment (NAWQA) Program - High Plains Regional Groundwater (HPGW) Study

Regional Transect Study - central High Plains

The central High Plains aquifer is the primary source of water for domestic, industrial, and irrigation uses in parts of Colorado, Kansas, New Mexico, Oklahoma, and Texas.

Publication available at: USGS Water-Resources Investigations Report: 2001-4028

Water-level declines of more than 100 feet in some areas of the aquifer have increased the demand for water deeper in the aquifer. The maximum saturated thickness of the aquifer ranged from 500 to 600 feet in 1999.

Water samples were collected once from each well in 1999 to measure vertical gradients in water chemistry in the aquifer.

Water samples were collected once from each well in 1999 to measure vertical gradients in water chemistry in the aquifer.

As the demand for deeper water increases, it becomes increasingly important for resource managers to understand how the quality of water in the aquifer changes with depth. In 1998-99, 13 nested monitoring wells at 4 sites in southwestern Kansas were completed at various depths in the central High Plains aquifer, and 1 monitoring well was completed in sediments of Permian age underlying the aquifer.
