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. 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.
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
(see map) 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 (see interpretive report
(PDF .75 MB)).
Water samples were collected once from each well in 1999 to measure vertical gradients in water chemistry in the aquifer.
