Saltwater in shallow aquifers in east-central and northeastern Louisiana and southeastern Arkansas
G. F. Huff, J.P. Bonck
1993, Open-File Report 93-494
The chemistry of water from irrigation and monitor wells in east-central Louisiana indicates the presence of saltwater in the Mississippi River alluvial aquifer and the uppermost part of the Jasper aquifer system. The salinity of this groundwater makes it unsuitable for use in irrigation of salt-sensitive crops. The geochemistry of...

1993, Professional Paper 1497-C
Most of the exposed bedrock in east- and south-central Alaska has been regionally metamorphosed and deformed during Mesozoic and early Cenozoic time. All the regionally metamorphosed rocks are assigned to metamorphic-facies units on the basis of their temperature and pressure conditions and metamorphic age. North of the McKinley and Denali...
