Literature Search:
The first activity
of the High Plains Regional Ground Water Study is to conduct a
combination electronic and manual literature search of available
water-related information across the study area. The collection
of references will include published reports and books, unpublished
Master's theses and doctoral dissertations, conference proceedings,
and journal articles. Furthermore, the bibliography will include
a co-author and subject indexes.
Retrospective Data Analysis:
Compile and analyze historical water-quality and ancillary
data sets from the eight States within the High Plains area. Ancillary data sets
include water-quality data, land-use data, water-use
data, hydrogeologic data, and other relevant environmental data
sets.
GIS Database Creation:
Compile, process, document, and review for public release, GIS
(Geographic Information System) data sets for the High Plains aquifer area.
Initial data sets in process are: 1) Extent of the Ogallala Formation in the
High Plains area; 2) hydrogeologic units; and 3) digitized/attributed well
locations from well-permit files for selected wells in SW Kansas and the Oklahoma
pan-handle region.
Reconnaissance Sampling--Ground-Water Age Dating:
One goal of the ground-water investigation of the High Plains NAWQA is to determine
the occurrence and distribution of water-quality constituents in recently recharged
ground water. Within the NAWQA program, this is done by conducting a Land-Use Study
in which monitoring wells are drilled and completed near the water table. Samples
of recently recharged ground water (<50 years old) are collected and analyzed to
examine if land-use affects from significant land-use activities (urban or
agricultural) can be detected. Because of the depth to water in the Ogallala
Formation aquifer can be highly variable(70-300 ft.), a reconnaissance sampling
effort will be conducted to determine if recently recharged water exists at
the water table. Five wells will be installed and these wells will be sampled
and analyzed for a suite of anthropogenic compounds and several ground-water age-dating
indicators.
