Selected Well Data Used in Determining Ground-Water Availability in the North and South Carolina Atlantic Coastal Plain Aquifer Systems

Abstract

Vertical coordinate information is referenced to the National Geodetic Vertical Datum of 1929 (NGVD 29). Horizontal coordinate information (latitudes and longitudes) is referenced to the North American Datum of 1983 (NAD 83). Transmissivity: The standard unit for transmissivity is cubic foot per day per square foot times foot of aquifer thickness [(ft 3 /d)/ft 2 ]ft. In this report, the mathematically reduced form, foot squared per day (ft 2 /d), is used for convenience.
