The three most important long island aquifers are the upper glacial aquifer, the lloyd aquifer, and the magothy aquifer the upper glacial aquifer is an unconfined aquifer directly underlying the ground surface the upper glacial aquifer was formed during the last ice age of note, the harbor hill moraine and ronkonkoma moraine represent two different glacial advances and run roughly east to west for the length of long island.
Between certain deeper upper glacial aquifer and shallow magothy aquifer sampling data using the modified stiff diagram technique, modified normed (m-n) stiff diagrams, and will be related to. Magothy and the lloyd aquifers in march-april 2000, and (3) the march-april 2000 water levels in the three aquifers in relation to those in 1997 it includes 1:125,000-scale maps of the water table in the upper glacial aquifer (pl 1) and the potentiometric-surface altitudes of the magothy and the lloyd aquifers (pls 2 and 3) in march-april 2000.
In sequence from shallowest to deepest, the li aquifers are: the upper glacial, the magothy and the lloyd aquifers a minor aquifer, the jameco , lies beneath the upper glacial, along the western south shore of long island. Estimation of hydraulic characteristics of the upper glacial and magothy aquifers at east meadow, new york, by use of aquifer tests by keith r prince and brian j schneider. An aquifer is an underground layer of water -bearing permeable rock , rock fractures or unconsolidated materials ( gravel , sand , or silt ) from which groundwater can be extracted using a water well the study of water flow in aquifers and the characterization of aquifers is called hydrogeology related terms include aquitard , which is a bed of low permeability along an aquifer, and.

Each year during march and april, the usgs conducts a synoptic survey of hydrologic conditions to define the spatial distribution of the water table and potentiometric surfaces within the three main water-bearing units underlying long island - the upper glacial, magothy, and lloyd aquifers.
Head differences (in ft) between magothy aquifer and confining layer wells and shallow upper glacial aquifer wells data from 1982 (but most data 1992 - 1998.
An aquifer is an underground layer of water-bearing permeable rock, used to refer to a small local area of ground water that occurs at an elevation higher than a regionally extensive aquifer the difference between perched and unconfined aquifers is their size (perched is smaller) in isotropic aquifers or aquifer layers the hydraulic. The aquifers are, from the shallowest to the deepest, the upper glacial, the magothy and the lloyd aquifers one minor aquifer, the jameco is also in use a the upper glacial aquifer: formed during the last ice age, the upper glacial is the aquifer closest to the surface the youngest aquifer formation, the upper glacial, was laid down during the last ice age, 10-15 million years ago. Groundwater wells in calvert county, maryland judith c wheeler, the difference between the potentiometric surfaces of the aquia aquifer, september 1982 and september 2003 in southern maryland, 1p of 2005-1006 by stephen e curtin, david c andreasen, judith c wheeler, potentiometric surface map of the magothy aquifer in southern.
