Two-dimensional ground-water flow model of the Cretaceous aquifer system of Lee County and vicinity, Mississippi
John Michael Kernodle
1981, Water-Resources Investigations Report 81-70
A two-dimensional ground-water flow model of the Eutaw-McShan and Gordo aquifers in the area of Lee County, Miss., was successfully calibrated and verified using data from six long-term observation wells and two intensive studies of areal water levels. The water levels computed by the model were found to be most...

Extraction and analysis of adenosine triphosphate from aquatic environments
Doyle W. Stephens, David J. Shultz
1981, Water-Resources Investigations Report 81-5
A variety of adenosine triphosphate (ATP) extraction procedures have been investigated for their applicability to samples from aquatic environments. The cold sulfuric-oxalic acid procedure was best suited to samples consisting of water, periphyton, and sediments. Due to cation and fulvic acid interferences, a spike with a known quantity of ATP...
