Ground-water flow and solute movement to drain laterals, western San Joaquin Valley, California; I, Geochemical assessment
S. J. Deverel, J.L. Fio
1990, Open-File Report 90-136
A study was undertaken to quantitatively evaluate the hydrologic processes affecting the chemical and isotopic composition of drain-lateral water in a drained agricultural field in the western San Joaquin Valley, California. The results of chemical and isotopic analysis of the samples and analysis of hydraulic-head data and drain-lateral flow data...
The difference between the potentiometric surfaces of the Magothy Aquifer of September 1986 and September 1988 in southern Maryland
Frederick K. Mack, David C. Andreasen, Stephen E. Curtin, Judith C. Wheeler
1990, Water-Resources Investigations Report 90-4038
A map was prepared that shows the net change in the potentiometric surface of the Magothy aquifer (in the Cretaceous Magothy Formation) in southern Maryland from the fall of 1986 to the fall of 1988. The map, based on water level measurements from 79 observation wells, shows that during the...
