D. E. Barr, L. R. Hayes, Thomas Kwader
1985, Water-Resources Investigations Report 84-4305
Increasing population in southern Okaloosa and Walton Counties have resulted in regional declines in the potentiometric surface of the upper limestone of the Floridan aquifer. Water levels have declined as much as 160 feet since 1940, and during peak seasonal demand as much as 190 feet. The Pensacola clay confining...

H. T. Buxton
1985, Water-Resources Investigations Report 84-4240
Base flows of the 29 major streams in southeast Nassau and southwest Suffolk Counties, New York, were statistically analyzed to discern the correlation among flows of adjacent streams. Concurrent base-flow data from a partial-record and a nearby continuous-record station were related; the data were from 1968-75, a period near hydrologic...

H. T. Buxton, T. E. Reilly
1985, Water-Resources Investigations Report 83-4209
By 1990, sanitary sewers in Nassau County Sewage Disposal Districts 2 and 3 and Suffolk County Southwest Sewer District will discharge to the ocean 140 cu ft of water/sec that would otherwise be returned to the groundwater system through septic tanks and similar systems. To evaluate the effects of this...
The Dakota aquifer near Pueblo, Colorado: Faults and flow patterns
E. R. Banta
1985, Water-Resources Investigations Report 85-4186
The Dakota Sandstone and the underlying Purgatoire Formation consisting of the Glencairn Shale and Lytle Sandstone Members form a board outcrop at the southeastern margin of the Canon City Embankment. The two formations form the Dakota aquifer, which supplies water to many domestic, stock, and irrigation wells in addition to...
