Superfund GIS - Physiographic Provinces, Aquifer Outcrops and Recharge Rates

The dataset was created to make generalizations about an aquifer's
capabilities of transport and recharge and to give names to those regions.

This dataset is a coverage of the physiographic provinces, aquifer outcrops
and recharge rates for Tennessee. Each polygon is attributed with its
associated physiographic region name (Miller, 1974), aquifer type and
composition (Connell and Barron, 1993, p. 2), and aquifer recharge rates (Hoos,
1990 p. 19).

Procedures_Used:
The linework was constructed by digitizing a map, prepared by Bradley and
Hollyday (1985), at a scale of 1:1,000,000. At the request of State officials,
aquifer boundaries in the West Tennessee area were modified to reflect work
reported by Parks and others (1982). The coverage was created for the
publication by Connell and Barron (1993). The coverage was validated and
attributed with physiographic names and aquifer recharge rates in 1997-98.

Revisions:
03/15/97 - Coverage was found valid, and attributed with physiographic names
04/03/98 - Aquifer recharge rates were attributed

Reviews_Applied_to_Data:
The dataset was reviewed by several Tennessee District personnel and was
deemed a valid dataset for use at the documented scale.
