This is a polygon dataset depicting the boundaries of
aquifer systems in the state of Louisiana and adjacent
areas of Texas, Arkansas and a portion of Mississippi.
These aquifers have been classified for recharge potential
from 'none' to 'high.'
The data set was developed by digitizing maps of the
'State Aquifer Recharge Map and Atlas Plates.' A
description and explanation of the maps of that atlas and
the aquifer systems named in this data set are contained in
'Donovan Boniol, Whitney J. Autin,
and Bradford C. Hanson, "Recharge Potential of Louisiana
A Supplement to the State Aquifer Recharge
Map and Atlas Plates," Louisiana Geological Survey Open
File Series No. 88-07.'
This data set provides the information of the State Aquifer
Recharge Atlas Plates in digital form.
The original hardcopy maps were prepared for the
Louisiana Department of Environmental Quality by the
Louisiana Geological Survey funded by the U.S.
Environmental Protection Agency in 1988.
Original Digitization of the paper maps was completed by
the Louisiana State University Remote Sensing and Image
Processing Laboratory for the LDEQ.
The metadata for this data set are encapsulated into several documents
and graphics files. The metadata are not complete if you did not

A few minor discontinuities in polygons (edge mismatches) occur at
edges of the original atlas tiles.
There is no data for the Mississippi River Delta region
250,000 map tile. This region is considered to have no recharge potential.
Although all polygons are coded for recharge potential, not
all have an assigned aquifer system name and code.
