Work plan for regional reconnaissance for selected herbicides and nitrate in ground water of the mid-continent United States, 1991
D.W. Kolpin, M. R. Burkart
1991, Open-File Report 91-59
An approach was developed to obtain a consistent, regional distribution of herbicide and nitrate data from near-surface aquifers in the corn and soybean producing region of the mid-continent. Near-surface aquifers are defined as those with the top of aquifer material within 50 feet of land surface, regardless of whether the...

Geohydrology and ground-water resources of Philadelphia, Pennsylvania
Gary N. Paulachok
1991, Water Supply Paper 2346
The aquifers underlying the 134.6-square-mile city of Philadelphia are divided by the Fall Line into the unconsolidated aquifers (chiefly sand and gravel) of the Coastal Plain and the consolidated-rock aquifers (chiefly schist of the Wissahickon Formation) of the Piedmont. Ground water is present under confined and unconfined conditions. The principal...
