Abstract

The data presented in this report are for selected wells 

in North and South Carolina that are located in the Atlantic 

Coastal Plain aquifer system. The data represent a partial 

inventory of wells in the study area and are to be used to 

update a regional flow model for North and South Carolina. 

This inventory includes a total of 813 wells in North Carolina 

and 461 wells in South Carolina. 

The well data include well-identification numbers, well 

locations by latitude and longitude, land-surface elevations, 

hole depths, well depths, open or screened interval(s), well 

diameters, depth to water, dates of water-level measurements, 

and aquifer assignment and transmissivity. Ground-water data 

presented in this report were obtained from field investigations 

and compiled from existing well records, both published and 

unpublished.

Introduction

An investigation was initiated in 2004 to improve the 

understanding of the Atlantic Coastal Plain (ACP) aquifer 

system in North and South Carolina. Objectives of this 

investigation were to improve the understanding of flow 

paths and recharge; evaluate ground-water and surface-water 

interactions; estimate the potential for reduced stream 

base-flow discharge to wetlands and estuaries resulting from 

increased ground-water withdrawals; and provide a scientifically based management tool for optimizing conjunctive 

water-use strategies and ground-water withdrawals in order to 

mitigate saltwater intrusion. As part of this investigation, well 

data were compiled from Federal and State data files and field 

investigations.

This investigation was funded by the U.S. Geological 

Survey (USGS) Ground-Water Resources Program. Other 

participants in the investigation include the South Carolina 

Department of Natural Resources (SCDNR), the South 

Carolina Department of Health and Environmental Control 

(SCDHEC), the North Carolina Department of Environment 

and Natural Resources (NCDENR), and the North Carolina 

Geological Survey.

Purpose and Scope

This report contains a partial inventory of wells in the 

North and South Carolina Coastal Plain that were installed 

prior to 2005. Data from these wells were compiled by the 

USGS in support of an investigation of ground-water availability in the Atlantic Coastal Plain aquifer system in North 

and South Carolina. Data collected at wells selected for this 

investigation were used to characterize recent and historic 

ground-water levels, identify the locations of ground-water 

pumping centers, and locate estimated hydraulic properties. 

The North and South Carolina Coastal Plain is a system 

of interlayered aquifers and confining units. The 13 aquifers 

in descending order are the surficial and Floridan aquifer 

systems, Tertiary Sand, Yorktown, Pungo River, Castle Hayne, 

Beaufort, Peedee, Black Creek, Middendorf, Cape Fear (upper 

and lower), and lower Cretaceous aquifers. Wells completed 

in pre-Cretaceous crystalline and sedimentary bedrock are not 

included in this inventory.

Description of Study Area

In North Carolina, the study area covers approximately 

22,500 square miles (mi2) and encompasses the Tidewater 

region (sometimes referred to as the Outer Coastal Plain) and 

the Inner Coastal Plain that lies between the Tidewater region 

and the Fall Line (Stuckey, 1965; Winner and Coble, 1996; 

fig. 1). The study area in North Carolina includes all or parts 

of 46 counties: Beaufort, Bertie, Bladen, Brunswick, Camden, 

Carteret, Chowan, Columbus, Cumberland, Currituck, Craven, 

Dare, Duplin, Edgecombe, Gates, Greene, Halifax, Harnett,

The sedimentary rocks in the North Carolina Coastal 

Plain consist of layers of gravel, sand, clay, and lesser 

amounts of marine limestone that range in age from Jurassic 

to post-Miocene (Winner and Coble, 1996). The Fall Line 

marks the approximate western limit of the strata and the 

boundary between the North Carolina Coastal Plain and 

Piedmont Physiographic Provinces. The strata dip eastward 

and progressively thicken from the Fall Line to the coast, 

reaching an estimated thickness of 8,500 feet (ft) near Cape 

Hatteras, North Carolina. The strata crop out in discontinuous 

belts that generally are parallel to the Fall Line. The number 

of individual sedimentary beds resting on crystalline basement 

rocks increases eastward (Winner and Coble, 1996).

In South Carolina, the study area covers approximately 

20,000 mi2 and encompasses the upper and lower portions 

of the Coastal Plain Physiographic Province (Aucott, 1996). 

The study area in South Carolina includes all or parts of 26 

counties: Aiken, Allendale, Bamberg, Barnwell, Beaufort, 

Berkeley, Calhoun, Charleston, Clarendon, Colleton, Darlington, Dillon, Dorchester, Florence, Georgetown, Hampton, 

Horry, Jasper, Lee, Lexington, Marion, Marlboro, Orangeburg, 

Richland, Sumter, and Williamsburg. 

The sedimentary rocks in the South Carolina Coastal 

Plain consist of layers of sand, clay, and lesser amounts of 

limestone that range in age from Late Cretaceous to Holocene. 

The Fall Line marks the approximate western limit of the 

strata and the boundary between the South Carolina Coastal 

Plain and Piedmont Physiographic Provinces. The strata dip 

and progressively thicken from the Fall Line to the southeast, 

reaching an estimated thickness of 2,700 ft in the southern part 

of South Carolina (Wait and Davis, 1986). The strata crop out 

in discontinuous belts that generally are parallel to the Fall 

Line. The sedimentary sequence unconformably overlies igneous and metamorphic rocks of Paleozoic age and consolidated 

red beds of early Mesozoic age (Chowns and Williams, 1983).

Previous Investigations

Well data for the North Carolina Coastal Plain are 

available from several previous investigations of ground-water 

resources. Comprehensive investigations of the hydrogeologic 

framework and ground-water flow were conducted by 

Winner and Coble (1996), Giese and others (1997), and 

Lautier (2001). A regional investigation of the hydrogeologic 

framework and ground-water resources was conducted by 

Lautier (1998b). Cardinell and others (1993) investigated the 

hydrogeologic framework beneath Camp Lejeune. Warner 

(1993) and Amsbaugh (1996) investigated the hydrogeology 

of the Castle Hayne aquifer system. Several investigations 

have been made of the potentiometric surfaces of Coastal Plain 

aquifers; among these are the Peedee aquifer by Brockman 

and others (1989); the Black Creek aquifer by Lyke and others 

(1989) and Strickland (1994, 1996, 2000); and the Cape Fear 

aquifer by Winner and others (1989) and Strickland (1994, 

1995, 1999). The ground-water resources of Wilson County 

were investigated by Winner (1976). Lautier (1998a) conducted a hydrogeologic assessment of the effects of proposed 

deepening of the Wilmington Harbor shipping channel for 

New Hanover and Brunswick Counties. Also for Brunswick 

County, Fine and Cunningham (2001) compiled ground-water 

data and described the hydrogeologic setting, and Harden and 

others (2003) defined the hydrogeology and ground-water 

quality. 

Data from previous investigations of ground-water 

resources in the South Carolina Coastal Plain include waterlevel data from studies conducted by Aucott and Speiran 

(1984); Clarke and West (1997); Harrelson, Conlon, and 

Harris (1997); Harrelson (1999); Harrelson and Falls (2002); 

and Waters (2003). Siple (1957, 1967) and Logan and Euler 

(1989) studied the geology and ground-water resources in 

the Savannah River Plant vicinity and in several Coastal 

Plain counties, including Aiken, Allendale, Bamberg, and 

Barnwell. Chowns and Williams (1983) studied the geology of 

pre-Cretaceous rocks in the Georgia Coastal Plain, and Wait 

and Davis (1986) studied the configuration and hydrology 

of pre-Cretaceous rocks in the southeastern Coastal Plain. 

Data from hydrogeologic investigations and observation-well 

networks in Aiken, Allendale, and Barnwell Counties were 

obtained by Logan (1987), Kuntz and Griffin (1988), Kuntz 

and others (1989), Gellici (1991), and Simones (1992). 

Burt and others (1987) collected hydrogeologic data from 

Port Royal Sound; Dennehy and others (1989) conducted a 

reconnaissance investigation of the hydrogeology beneath 

the Savannah River Plant waste-processing facility; Bledsoe 

and others (1990) conducted a baseline hydrogeologic 

investigation of the Savannah River Site; and Aadland and 

others (1995) investigated the hydrogeologic framework of 

west-central South Carolina. Aucott (1996) described the 

hydrology of the southeastern Coastal Plain in South Carolina 

and parts of Georgia and North Carolina; and specific to South 

Carolina, Marine (1979) defined the hydrology of buried 

crystalline rock at the Savannah River Plant near Aiken; Cahill 

(1982) described the hydrology of the low-level radioactive 

solid-waste burial site near Barnwell; Park (1985) described 

the ground-water resources of Charleston, Berkeley, and 

Dorchester Counties; Speiran and Lichtler (1986) investigated 

the ground-water resources of shallow aquifers in the Grand 

Strand; Dale and Park (1999) studied the irrigation-supply 

potential of the shallow aquifer beneath Hilton Head Island; 

and Petkewich and others (2004) conducted a hydrologic and 

water-quality evaluation of aquifer storage and recovery in the 

Santee Limestone/Black Mingo aquifer beneath Charleston. 

Coastal Plain aquifer tests were conducted by Aucott and 

Newcome (1986) and Newcome (1993). Hockensmith (2003a, 

b) defined the potentiometric surfaces of the Black Creek and 

Middendorf aquifers, respectively. Hydraulic characteristics 

and stream-aquifer relations were investigated in the Upper 

Introduction 
Cretaceous and Lower Tertiary aquifers of eastern Alabama, 

Georgia, and western South Carolina by Faye and McFadden 

(1986) and Faye and Mayer (1990). Four environmental 

reports were prepared by the Westinghouse Savannah River 

Company under contract to the U.S. Department of Energy to 

describe activities at the Savannah River Site—the groundwater monitoring program (1990), the environmental report for 

1990 (1991), and the Environmental Protection Department’s 

well inventories (1992, 1995). Annual water-resources data for 

South Carolina were compiled by Bennett and others (1993, 

1994); ground-water and precipitation data for South Carolina 

were collected by Conrads and others (1994); selected well 

data from the Savannah River Site in South Carolina and 

Georgia were collected by Harrelson, Falls, and Clarke (1997); 

and water-resources data for South Carolina for 2000-2001 

were collected by Harwell and others (2004).

Well Data

Ground-water data presented in this report were obtained 

during field investigations and compiled from published and 

unpublished well data (table 1, p. 29). The well data include 

the USGS and State identifiers, well locations by latitude and 

longitude, land-surface altitudes, well depths, open or screened 

intervals, date and depth of water-level measurements, and 

aquifer assignment and transmissivity. 

Well data from published reports, State well reports, 

and well driller’s reports were verified for accuracy. Existing 

data were compiled from USGS records and several State, 

county, and other Federal agencies. Data for many wells in 

North Carolina were obtained from data files of the NCDENR 

Divisions of Water Quality and Water Resources. Data for 

many wells in South Carolina were obtained from the U.S. 

Department of Energy, Westinghouse Savannah River Site, 

SCDNR, and SCDHEC. 

Well-Numbering System

The USGS uses the same well-numbering system to store 

ground-water data for North and South Carolina. The wells are 

sequentially numbered in each county using an alphanumeric 

well designation. The two- or three-letter prefix refers to 

the county, and the number refers to the chronological order 

in which wells were catalogued in the county (table 1). For 

example, the 14th well inventoried in Aiken County, South 

Carolina, would be designated AK-14.

The State agencies in North and South Carolina assign 

identifiers to wells based on a latitude- and longitude-grid 

system. This grid system divides North and South Carolina 

into a matrix of 5-minute latitude by 5-minute longitude 

cells. Each of these cells has a corresponding number and 

letter(s), such as 40W. Each of the cells is further divided into 

25 subcells, 1-minute latitude by 1-minute longitude with a 

corresponding letter “a” through “y”, such as 40W-q. As each 

well is located within the 1-minute grid, a sequential number 

is assigned, starting with the first well located. Thus, the 5th

well inventoried in the 40W-q cell would be assigned the 

number 40W-q5. This naming convention is referred to in this 

report as “State identifiers” (table 1).

The well identifiers assigned by different entities vary 

within the study area. For example, AK-867 and 38W-n7 

identify the same well. Both well identifiers, when available, 

are presented in table 1 at the end of this report.

Data Presentation and Storage

The data presented in this report have been entered into 

the USGS national database, National Water Information 

System (NWIS) Ground-Water Site Inventory System (GWSI), 

and can be accessed online at http://waterdata.usgs.gov/nwis/

gw. The data were evaluated for accuracy before and after 

entry into the database. Ground-water data are stored in the 

GWSI database in accordance with specific NWIS guidelines 

(Mathey, 1989). Additional well data are available from the 

USGS North Carolina Water Science Center in Raleigh and 

the USGS South Carolina Water Science Center in Columbia.

Selected well locations were obtained by using a global 

positioning system (GPS) or by plotting the locations on a 

USGS 1:24,000-scale topographic map. Altitudes interpolated 

from topographic maps are accurate within one-half the 

contour interval of the map. Thus, if the contour interval on 

the topographic map is 10 ft, the interpreted altitude for the 

well is plus or minus 5 ft. Well depth is the reported finished 

depth of the well, in feet below land surface. Depth to water 

is the level to which water rises in a tightly cased well, in feet 

below land surface. A minus sign (-) precedes the measurement for wells with a water level above land surface. Dates are 

provided for all water-level measurements. 

The assigned aquifer is the hydrogeologic unit(s) 

designated for each well on the basis of the altitude of the 

open or screened interval(s). The altitude of the top of each 

hydrogeologic unit was taken from Winner and Coble (1996) 

and Aucott (1996) for North and South Carolina, respectively.

Estimates of aquifer transmissivity are presented in the 

mathematically reduced form of foot squared per day (ft2/d). 

These data are from published and unpublished sources and 

vary in quality. If the value for the transmissivity is taken 

from a published source, a reference for the data is provided. 

Unpublished data were calculated, analyzed, and approved 

by the USGS. These estimates of transmissivity are presented 

only as an indication of the transmissive characteristics of the 

aquifer to store and release water.

Hydrogeologic Units

The hydrogeologic units in the North and South Carolina 

Costal Plain differ in number, nomenclature, age, and 

lithology; therefore, the hydrogeologic units have not been 

 
regionally classified at the North Carolina and South Carolina 

border. In this report, the established nomenclature of previous 

hydrogeologic framework studies in North and South Carolina 

are used as the basis for aquifer and ground-water-level 

assignments. Primarily, the hydrogeologic framework from the 

Regional Aquifer-System Analysis (RASA) investigations are 

used (Aucott, 1996; Winner and Coble, 1996).

In North Carolina, the Coastal Plain sediments are 

divided into 10 regional to subregional aquifers and intervening confining units. The aquifers consist of layers of sand or 

limestone and are separated by layers of silt, clay, or lowpermeability limestone. In descending order, the aquifers are 

the surficial, Yorktown, Pungo River, Castle Hayne, Beaufort, 

Peedee, Black Creek, upper Cape Fear, lower Cape Fear, and 

lower Cretaceous (Winner and Coble, 1996; fig. 2).

In South Carolina, the Coastal Plain sediments are 

divided into six regional to subregional aquifers and intervening confining units. The aquifers consist of layers of sand 

or limestone and are separated by layers of silt, clay, or 

low-permeability limestone. In descending order, the aquifers 

are the surficial, Floridan, Tertiary Sand, Black Creek, 

Middendorf, and Cape Fear (Aucott, 1996). The nomenclature 

and stratigraphies of geologic and hydrogeologic units used 

in this study are compared to those presented in previous 

investigations (fig. 2). 

Surficial Aquifer 

In North Carolina, the surficial aquifer of Quaternary 

age covers a large portion of the Coastal Plain (fig. 3) and 

is composed of distinct geologic units of differing ages and 

lithologies. Geologic or morphostratigraphic names have been 

given to some of the surficial deposits by previous investigators; see Winner and Coble (1996) for specific information on 

the history of the nomenclature.

The surficial aquifer consists of fine sand, silt, clay, shell, 

and peat beds deposited under shallow marine or estuarine 

conditions. Additionally, discontinuous deposits of coarsegrained materials are indicative of relict beach ridges and 

flood-plain alluvial deposits. West of the Tidewater region, 

the composition of the surficial aquifer becomes coarser and 

more poorly sorted. Where present, these sediments range in 

thickness from a few feet to as much as 30 ft and generally are 

described as Pleistocene terrace deposits that unconformably 

overlie rocks of Cretaceous to Miocene age. The Yorktown 

confining unit separates the surficial aquifer from the Yorktown aquifer (Winner and Coble, 1996). 

In South Carolina, the marine terrace and alluvial 

deposits that make up the surficial aquifer generally are less 

than 50 ft thick and pinch out at the boundary of the upper 

and lower Coastal Plain (Doering, 1960). Because no wells

SOUTH CAROLINA

 
completed in the surficial aquifer in South Carolina are listed 

in table 1, figure 3 is limited to the North Carolina Coastal 

Plain. The marine terrace and alluvial deposits are composed 

primarily of sand, shell, and clay that were deposited during 

the Pleistocene Epoch (Siple, 1946). The marine sediments of 

the surficial aquifer contain water under unconfined conditions 

(Campbell and Heeswijk, 1996). The surficial aquifer in South 

Carolina is present over the entire Coastal Plain and overlies 

the Floridan aquifer system and the Black Creek aquifer in 

western parts of the lower Coastal Plain and in eastern parts of 

the upper Coastal Plain, respectively (Aucott, 1996).

Floridan Aquifer System

The Floridan aquifer system is not present in North 

Carolina; therefore, the discussion of the Floridan aquifer 

system is limited to South Carolina (fig. 4). The marine 

deposits of Late to Middle Eocene age include the permeable 

parts of the Santee Limestone, as redefined locally by Aucott 

and others (1987). The Floridan aquifer system extends over 

the southwestern one-third of the Coastal Plain in South 

Carolina. The thickness of the aquifer system ranges from less 

than 1 ft near the outcrop area near the Fall Line to more than 

700 ft near the southernmost coast (Aucott, 1996). Toward the 

northwest, the Floridan aquifer system gradually grades into 

the Tertiary Sand aquifer system (Campbell and Heeswijk, 

1996).

The Floridan aquifer system is confined by the Miocene 

Hawthorne Formation that consists of low-permeability, 

phosphatic clayey sand and phosphatic sandy clay. The clay 

beds are discontinuous in many areas where the Floridan 

aquifer system exists (Campbell and Heeswijk, 1996).

Tertiary Sand Aquifer

The Tertiary Sand aquifer system is not present in North 

Carolina; therefore, the discussion of the Tertiary Sand aquifer 

system is limited to South Carolina (fig. 4). The Tertiary 

Sand aquifer system is the updip equivalent of sediments 

that compose the Floridan aquifer system and underlies the 

Floridan aquifer system in some areas. In South Carolina, 

the Tertiary Sand aquifer system extends from the Fall Line 

to the coast. The aquifer system is composed of sediments 

that include the Congaree, Barnwell, McBean, and the upper 

part of the Black Mingo Formations. These formations are 

composed of fine to medium sand and clay, and commonly are 

light greenish yellow to orange in color. The Tertiary aquifer 

system varies in thickness and is over 400 ft thick immediately 

updip of the Floridan aquifer system limit (Aucott, 1996).

Yorktown Confining Unit

The Yorktown confining unit is not present in South 

Carolina; therefore, the discussion of the Yorktown confining 

unit is limited to North Carolina. The hydrologic boundary 

between the surficial and Yorktown aquifers is the Yorktown 

confining unit which is present only above the Yorktown 

aquifer. In limited areas, the Yorktown confining unit may 

contain the youngest beds in the Yorktown Formation. These 

clay beds are of Pliocene age. The confining unit is composed 

mostly of clay and sandy clay that locally includes beds of 

fine sand or shells. Where the Yorktown aquifer is present, the 

confining unit ranges in thickness from 70 ft in the northeast 

to less than 10 ft in the south (Winner and Coble, 1996).

Yorktown Aquifer 

The Yorktown aquifer is not present in South Carolina; 

therefore, the discussion of the Yorktown aquifer is limited to 

North Carolina (fig. 5). The Yorktown aquifer extends through 

the northern half of the North Carolina Coastal Plain from the 

Fall Line to beyond the coastline. The eastward slope of the 

top of the aquifer is approximately 7 ft per mile (ft/mi), and 

the Yorktown aquifer is 300 ft thick near the coast (Winner 

and Coble, 1996). West of the Tidewater region, the Yorktown 

aquifer thins to less than 20 ft and is discontinuous as a result 

of erosion from local streams (Winner and Coble, 1996).

The Yorktown aquifer is composed primarily of fine sand 

and silty and clayey sand with shell and shell beds throughout 

the unit. The dominant lithology of the Yorktown aquifer 

over much of the Inner Coastal Plain is fine sand. Along the 

easternmost Coastal Plain, limestone rocks of upper Miocene 

age were reported by Brown and others (1972). Additionally, 

Ward and Blackwelder (1980) described the Yorktown aquifer 

as containing some lag deposits of coarse sand and pebbles in 

parts of northeastern North Carolina. The Yorktown aquifer 

and confining unit are more or less entirely overlain by the 

surficial aquifer and receive recharge from this overlying 

aquifer (Winner and Coble, 1996).

Pungo River Confining Unit 

The Pungo River confining unit is not present in South 

Carolina; therefore, the discussion of the Pungo River 

confining unit is limited to North Carolina. In most cases, the 

hydrologic boundary between the Yorktown and Pungo River 

aquifers is the Pungo River confining unit. The continuous 

clays of the lowermost Yorktown Formation and the upper 

clay beds of the Pungo River Formation compose the Pungo 

River confining unit.

The Pungo River confining unit, which is composed 

mainly of clay, has less than 10 percent sand content and 

varies in thickness from approximately 150 ft downdip in the 

east to less than 10 ft along the western margins of the Pungo 

River aquifer. The Pungo River confining unit has an average 

thickness of about 55 ft (Winner and Coble, 1996).

Pungo River Aquifer 

The Pungo River aquifer is not present in South Carolina; 

therefore, the discussion of the Pungo River aquifer is limited 

to North Carolina. The Pungo River aquifer is composed of 

permeable sediments, and its extent is limited to the eastern 

section of the northern Coastal Plain of North Carolina. No 

wells completed in the Pungo River aquifer are listed in table 

1; therefore, there is no corresponding figure. The thickness 

of the Pungo River aquifer averages 15 ft near its western and 

northern limits, and the aquifer dips eastward toward the Outer 

Banks at 10 to 12 ft/mi where its thickness increases to more 

than 200 ft (Winner and Coble, 1996).

The Pungo River aquifer is composed primarily of 

fine- to medium-grained sediments with substantial phosphatic 

material. These sediments indicate that the aquifer was 

deposited in an offshore environment; however, some beds of 

course sand may have been deposited in estuarine or nearshore 

environments. In selected areas of eastern North Carolina, the 

Pungo River aquifer is mined for phosphatic sand (Winner and 

Coble, 1996).

Castle Hayne Confining Unit

The Castle Hayne confining unit is not present in South 

Carolina; therefore, the discussion of the Castle Hayne 

confining unit is limited to North Carolina. In most cases, the 

hydrologic boundary between the Pungo River and Castle 

Hayne aquifers is the Castle Hayne confining unit. This 

confining unit is thin and patchy over much of its area and is 

composed primarily of clay, sandy clay, and clay with sandy 

streaks. The Castle Hayne confining unit contains a large 

amount of sand in its matrix, which allows substantial leakage 

between the Castle Hayne aquifer and the other overlying 

aquifers. The Castle Hayne confining unit ranges in thickness 

from 10 to 25 ft and has an average thickness of approximately 

14 ft (Winner and Coble, 1996).

Castle Hayne Aquifer

The Castle Hayne aquifer is not present in South 

Carolina; therefore, the discussion of the Castle Hayne aquifer 

is limited to North Carolina (fig. 6). The Castle Hayne aquifer 

is the most productive aquifer in North Carolina (Winner and 

Coble, 1996). The carbonate rocks that compose the aquifer 

have considerably higher hydraulic conductivities than the 

clastic aquifers in North Carolina. 

The Castle Hayne aquifer includes the hydraulically 

connected overlying River Bend Formation of Oligocene 

age (Ward and others, 1978), rocks that are lithologically 

similar to the Eocene Castle Hayne limestone (Brown and 

others, 1972), and possibly older continuous permeable units 

(Winner and Coble, 1996). The Castle Hayne aquifer consists 

of alternating beds of marine limestone composed of sandy, 

shelly, dolomitic limestone and sand. Limestone dominates 

the lithology throughout the upper one-third to one-half of the 

aquifer thickness, and sand is the dominate permeable material 

in the lower section of the aquifer. The aquifer dips eastward 

at 13 to 15 ft/mi and approaches a thickness of 1,200 ft at 

Cape Hatteras (Winner and Coble, 1996). 

Beaufort Confining Unit

The Beaufort confining unit is not present in South 

Carolina; therefore, the discussion of the Beaufort confining 

unit is limited to North Carolina. The Beaufort confining 

unit is composed of the uppermost sediments of the Beaufort 

Formation of Paleocene age and possibly some younger clay, 

silt, and sandy clay. In some sections, the confining unit is 

composed of a distinct clay with interbedded fine sand or 

silt. The confining unit thickness ranges from zero to 80 ft 

and is more than 50 ft near the coastline. The thickness of the 

confining unit averages 24 ft (Winner and Coble, 1996).

Beaufort Aquifer

The Beaufort aquifer is not present in South Carolina; 

therefore, the discussion of the Beaufort aquifer is limited to 

North Carolina (fig. 7). The Beaufort aquifer is composed 

mainly of marine rocks of the Beaufort Formation of Paleocene age; however, the aquifer may include permeable units 

of younger rock that directly overlie the formation as well as 

older Cretaceous rocks that directly underlie the formation. An 

unconformity exists between the Beaufort Formation and the 

overlying and underlying rocks, respectively. 

The Beaufort aquifer is composed of fine to medium 

glauconitic sand, clayey sand, and clay beds with minor beds 

of shell and limestone up to 6 ft thick. The top of the aquifer 

dips eastward at 14 to 33 ft/mi. The thickness of the Beaufort 

aquifer ranges from less than 1 ft to 171 ft, and the average 

thickness is approximately 90 ft. A nearby offshore limit to 

the aquifer is indicated by an increase in clay content and 

a corresponding thickening of the overlying confining unit 

(Winner and Coble, 1996). 

Peedee Confining Unit

The Peedee confining unit is not present in South 

Carolina; therefore, the discussion of the Peedee confining unit 

is limited to North Carolina. The intermittent Peedee confining 

unit is composed of clay, silty clay, and sandy clay. The 

lithologies of the Peedee confining unit cannot be correlated 

with a distinct geologic unit; however, where the Peedee 

confining unit is missing and the Beaufort aquifer directly 

overlies the Peedee aquifer, the lithologies are recognized as 

denoting the Cenozoic-Mesozoic boundary. In other areas 

where the Peedee confining unit is present, the lithology may 

represent material spanning a longer period of geologic time. 

In areas where the surficial and Castle Hayne aquifers 

directly overly the Peedee confining unit, clayey sand or sandy 

clay in the Peedee matrix allows water to move into or out of 

the Peedee aquifer more easily than in other areas. Generally, 

the hydraulic conductivities of the Peedee confining unit are 

very low. It should be noted that the Peedee confining unit is 

not always present above the Peedee aquifer, especially where 

the aquifer extends farther to the west.

The thickness of the Peedee confining unit ranges from 

less than 1 ft to 60 ft, with an average thickness of 25 ft. In 

areas where streams have cut directly into the Peedee aquifer, 

the Peedee confining unit may be absent; in other areas, the 

Peedee confining unit may be very thin or absent (Winner and 

Coble, 1996).

Peedee Aquifer

The Peedee aquifer is not present in South Carolina; 

therefore, the discussion of the Peedee aquifer is limited 

to North Carolina (fig. 8). The Peedee Formation is not 

recognized in northeastern North Carolina north of Albemarle 

Sound. The Peedee aquifer is composed mainly of marine 

sands of Late Cretaceous age; however, the aquifer may 

include permeable sand units of younger and older ages 

in some localities. The Peedee Formation disconformably 

overlies the Black Creek Formation (Sohl and Christopher, 

1983; Winner and Coble, 1996). 

The Peedee aquifer is composed of gray to greenish-gray 

fine to medium sand with some glauconite interbedded with 

gray to black marine clay and silt. In some localities, the sand 

is interlayered with impure limestone, shell beds, and thin 

beds of consolidated calcareous sandstone. The top of the 

aquifer dips eastward at an average rate of approximately 24 

ft/mi and ranges from 10 to 33 ft/mi from the intermargins 

of the aquifer and along the coast, respectively. The aquifer 

thickens from less than 1 ft along its western limits to greater 

than 300 ft near the South Carolina border (Winner and Coble, 

1996). 

Black Creek Confining Unit

The Black Creek confining unit occurs in North and 

South Carolina. In North Carolina, the Black Creek confining 

unit is composed of the uppermost beds of the Black Creek 

Formation and consists of clay, silty clay, and sandy clay. 

Depending on the location within the section, the Black 

Creek confining unit is made up of sediments of the Beaufort, 

Yorktown, and Peedee Formations. In areas where the Black 

Creek confining unit is highly dissected, the uppermost clays 

of the Middendorf Formation compose the unit (Winner and 

Coble, 1996). 

The average thickness of the Black Creek confining unit 

is approximately 45 ft, with a maximum thickness of more 

than 160 ft. The confining unit thickens over the eastern 

portions of the Coastal Plain. In the Sand Hills area of North 

Carolina, the Black Creek confining unit is defined as the first 

clay bed that occurs at the top of the Middendorf Formation 

and averages approximately 10 ft in thickness (Winner and 

Coble, 1996).

In South Carolina, clayey sediments and the lower 

portion of the Black Mingo Formation of Paleocene age 

compose the Black Creek confining unit (Aucott, 1996). 

Additionally, the low-permeability upper Cretaceous Peedee 

Formation—composed of gray calcareous, glauconitic, fine 

to medium sand; coquina; and fossiliferous, gray calcareous 

clay—acts as the upper confining unit for the Black Creek 

aquifer. In other localities, clayey sediments of Paleocene age 

may compose some of the unit. Near the South Carolina coast, 

the aquifer is approximately 50 ft thick. The Black Creek 

confining unit is the most effective confining unit in the South 

Carolina Coastal Plain (Campbell and Heeswijk, 1996).

Black Creek Aquifer

The Black Creek aquifer occurs in both North and South 

Carolina (figs. 9, 10). In North Carolina, the Black Creek 

aquifer is composed of the Black Creek and Middendorf 

Formations and their downdip equivalents of Late Cretaceous 

age. It is reported that the Black Creek and Middendorf 

Formations unconformably overlie older Cretaceous beds 

(Heron and Wheeler, 1964). 

The Black Creek aquifer is composed of thinly laminated, 

gray to black clay interlayered with gray and tan sands, which 

indicate a lagoonal to marine depositional environment. Shell, 

glauconitic, and organic material, especially lignite, characterize the sediments of the Black Creek Formation (Winner and 

Coble, 1996).

The Middendorf Formation is a nonmarine fluvial 

sequence that may include light color, white, tan, and red 

kaolinitic clay (clay balls and fragments) and sediments 

composed of a heterogeneous mix of fine to medium sand 

and silty-clay beds, coarse channel sands, and thin laminated 

beds of sand and clay. These sediments are typical of deltaic 

sedimentary environments that commonly contain crossbedding, lenses, pinch outs, and facies changes. 

In general, the Black Creek aquifer dips more steeply in 

the north than in the south and dips east-southeast at a rate 

of approximately 17 ft/mi; in the south, however, the aquifer 

dips about 12 ft/mi. The aquifer is as much as 400 ft thick 

along portions of the North Carolina coast (Winner and Coble, 

1996).

In South Carolina, the Black Creek aquifer consists 

primarily of sediments of the Black Creek Formation but may 

locally include sediments of the overlying Peedee Formation 

of Cretaceous age and the underlying Middendorf Formation. 

The thickness of the aquifer generally is between 300 and 600 

ft, except for areas that parallel the Fall Line in the western 

Coastal Plain where the Black Creek Formation pinches out 

(Aucott, 1996). Campbell and Heeswijk (1996) reported a 

thickness for the Black Creek aquifer of 900 ft near the coast. 

Middendorf Confining Unit

The Middendorf confining unit is not defined in North 

Carolina as it is in South Carolina. The sediments that make 

up the Black Creek aquifer, Middendorf confining unit, and 

Middendorf aquifer are grouped together as the Black Creek 

aquifer in North Carolina; therefore, the discussion of the 

Middendorf confining unit is limited to South Carolina. The 

Middendorf confining unit occurs between the Black Creek 

and Middendorf aquifers in South Carolina. The Middendorf 

confining unit is composed primarily of the lower sandy clay 

of the Black Creek Formation (Aucott, 1996). In the Charleston area, the confining unit is formed by low-permeability 

sediments composed of the lower silt-clay member of the 

Cane Acre Formation (Gohn, 1992). Downdip, the lithology 

is calcareous, silty, and sandy clay of a medium to light gray 

color; in the updip portions of the confining unit, however, the 

lithology is sandy clay of the lower portion of the Black Creek 

Formation (Campbell and Heeswijk, 1996).

Middendorf Aquifer

The Middendorf aquifer is not defined in North Carolina 

as it is in South Carolina (fig. 11). The sediments that make 

up the Black Creek aquifer, Middendorf confining unit, and 

Middendorf aquifer are grouped together as the Black Creek 

aquifer in North Carolina; therefore, the discussion of the Middendorf aquifer is limited to South Carolina. The Middendorf 

aquifer occurs throughout the Coastal Plain and is composed 

primarily of sediments of the Middendorf Formation of Late 

Cretaceous age and locally the sands of the Shepherd Grove 

Formation (Gohn, 1992). Locally it may include sediments 

from the overlying Black Creek Formation or the underlying Cape Fear Formation; however, near Florence, South 

Carolina, the Middendorf aquifer is composed of sediments 

of the Middendorf Formation only (Curley, 1990; Campbell 

and Heeswijk, 1996). In the subsurface and outcrop areas 

of the upper Coastal Plain, the deltaic to fluvial sediments 

of the Middendorf Formation are composed of sand that is 

commonly interfingered with lenses of clay. The sand and clay 

of the deltaic sediments have characteristic colorations. The 

sand colors may be light gray or white to buff while the clay 

coloration may be white, pink, or purple. In downdip areas, the 

lithologies of the Black Creek and Middendorf Formations are 

similar and consist of thinly laminated layers of gray fine to 

medium micaceous sand and dark gray to black clay. Campbell and Heeswijk (1996) describe the downdip subsurface 

unit as consisting of coarse-grained sands and interbedded, 

dark, lignitic clays deposited in a variety of marginal-marine 

environments, such as delta plain or estuarine. The maximum 

thickness of the Middendorf aquifer is approximately 400 ft; 

however, the average thickness of the aquifer is generally 200 

ft. The aquifer thickens from a feathering edge near the Fall 

Line toward the coast (Aucott, 1996). Near the Atlantic coast, 

the aquifer is about 300 ft thick (Campbell and Heeswijk, 

1996).

Upper Cape Fear Confining Unit or Unnamed 

Confining Unit 

In North Carolina, the upper Cape Fear confining unit 

separates the underlying upper Cape Fear aquifer from the 

overlying Black Creek aquifer. The upper Cape Fear confining 

unit consists of clay, silty-clay, and sandy-clay beds that 

generally are continuous in nature. Depending on location 

within the North Carolina Coastal Plain, the confining unit 

may contain sediments of the lower Middendorf, Black Creek, 

and Yorktown Formations. The upper Cape Fear confining 

unit generally thickens toward the coast with a maximum 

thickness of approximately 100 ft in some locations, although 

the average thickness of the confining unit is approximately 48 

ft (Winner and Coble, 1996).

In South Carolina, an unnamed confining unit separates 

the overlying Middendorf aquifer from the underlying Cape 

Fear aquifer. This unnamed confining unit is composed of 

massive, noncalcareous clay that is grayish to dusky yellow 

in color and contained in the upper to middle part of the Cape 

Fear Formation (Gohn, 1992; Campbell and Heeswijk, 1996). 

In the eastern portions of the South Carolina Coastal Plain, 

the confining unit is very effective in separating the overlying 

Middendorf from the underlying Cape Fear aquifer (Aucott, 

1996).

Cape Fear Aquifer

The Cape Fear aquifer is present in North and South 

Carolina. In South Carolina, the Cape Fear aquifer is defined 

as one continuous aquifer (fig. 11). In North Carolina, 

however, the Cape Fear aquifer is defined as having an upper 

and lower aquifer separated by the lower Cape Fear confining 

unit. 

In South Carolina, the Cape Fear aquifer of upper 

Cretaceous age is the lowermost aquifer in the Coastal Plain 

aquifer system, although the aquifer’s extent is not well 

defined. The aquifer may be present only in the eastern portion 

of the upper Coastal Plain and in the underlying lower Coastal 

Plain (Aucott, 1996). In North Carolina, two hydrologic units 

can be differentiated in the Cape Fear sediments of Cretaceous 

age on the basis of differences in the hydraulic heads of each 

unit.

The Cape Fear aquifer thins near the Fall Line and 

thickens toward the coast. The Cape Fear aquifer is composed 

of substantial red clay with undeveloped, poorly sorted quartzand feldspar-rich sands. In the updip part of the aquifer, thin 

beds of unconsolidated sands are present and may indicate 

meandering channel deposits. The downdip part of the aquifer 

is composed of yellowish-gray, red, and brown noncalcareous 

clays and tan feldspar sands (Gohn, 1992). Because of the 

Cape Fear aquifer’s substantial clay content, it is not considered a regionally significant drinking-water supply in South 

Carolina (Campbell and Heeswijk, 1996).

Upper Cape Fear Aquifer

The upper Cape Fear aquifer in North Carolina (fig. 12) 

consists of sediments of the upper Cape Fear Formation and 

in downdip areas may include some of the lowermost beds of 

the Middendorf Formation. In outcrop, the Cape Fear aquifer 

consists of alternating beds of sand and clay that range from 

less than 1 ft to as much as 15 ft. A vertical gradation from 

sand to clay can be ascertained from the exposed surface as 

can thin conglomerates of mudstone fragments and quartz 

pebbles. The top of the Cape Fear aquifer has a general 

northeast strike and slope of 50 ft/mi to the southeast. Along 

the western edge of the Cape Fear aquifer, the sand units generally pinch out; however, a thick clay section may be present 

between basement rocks and the upper Cape Fear aquifer. In 

many places, the aquifer does not extend to the Fall Line. The 

average thickness of the aquifer is approximately 100 ft; from 

its western edge, the aquifer thickens in an eastward direction 

from approximately 10 to 500 ft (Winner and Coble, 1996).

Lower Cape Fear Confining Unit

The lower Cape Fear confining unit separates the upper 

and lower Cape Fear aquifers in North Carolina. This confining unit is composed of sandy-clay and clay beds of the Cape 

Fear Formation of Cretaceous age. Additionally, younger 

Tertiary sediments in the northwestern Coastal Plain may 

confine the lower Cape Fear aquifer. The Cape Fear confining 

unit pinches out along its western edge. In this area, the upper 

and lower Cape Fear aquifers coalesce. In other areas, the confining unit merges with younger clay beds or truncates against 

the bedrock and forms a substantial clay section overlying 

the bedrock. This confining unit thickens downdip and ranges 

from less than 1 ft to 100 ft, with the average thickness being 

approximately 52 ft (Winner and Coble, 1996).

Lower Cape Fear Aquifer 

The older sands of the Cape Fear Formation compose the 

lower Cape Fear aquifer (fig. 13). This formation is truncated 

by the eastward-sloping bedrock surface beneath the formation. Thus, the extent of the lower Cape Fear aquifer does 

not extend as far to the west as the upper Cape Fear aquifer, 

and the aquifer dips 15 to 55 ft/mi in an easterly direction. 

Along the western margin, the aquifer is only a few feet thick; 

however, the thickness increases to over 400 ft in the eastern 

Coastal Plain. The average thickness of the lower Cape Fear 

aquifer is approximately 175 ft (Winner and Coble, 1996).

Lower Cretaceous Confining Unit

The Lower Cretaceous confining unit is not present 

in South Carolina; therefore, the discussion of the Lower 

Cretaceous confining unit is limited to North Carolina. This 

confining unit separates the lower Cape Fear and Lower 

Cretaceous aquifers and is not present adjacent to the North 

and South Carolina State boundary. This confining unit 

is composed of sandy-clay and clay beds of Early to Late 

Cretaceous age. In some areas, the thickness of the confining 

unit is as much as 70 ft, and the average thickness is approximately 44 ft (Winner and Coble, 1996).

Lower Cretaceous Aquifer 

The Lower Cretaceous aquifer is not present in South 

Carolina; therefore, the discussion of the Lower Cretaceous 

aquifer is limited to North Carolina. The Lower Cretaceous 

aquifer is the lowermost aquifer in North Carolina. This 

aquifer is composed of major water-bearing zones in the 

Coastal Plain. The sediments that compose the Lower Cretaceous aquifer typically are regarded as Early Cretaceous in 

age and encompass approximately one-third to one-half of the 

entire thickness of the Coastal Plain adjacent to the northern 

coast line of North Carolina. The Lower Cretaceous aquifer 

is composed of interbedded marine and nonmarine sediments 

(Spangler, 1950). The marine beds are composed predominately of limestone that may be sandy or dolomitic with minor 

amounts of anhydrite. The nonmarine beds are composed of 

lignitic, micaceous, and arkosic sand, gravely sand, and shale 

that vary in color (Maher, 1971).

From the western limits to near the coast, the Lower 

Cretaceous aquifer dips east at a slope of approximately 15 

to 25 ft/mi. The aquifer is approximately 25 ft thick at its 

western limits and thickens to more than 800 ft downdip. The 

sediments of the Lower Cretaceous aquifer are not known to 

be present along the North and South Carolina State border 

(Winner and Coble, 1996).

Summary

This report presents the results of an inventory of 813 

wells in North Carolina and 461 wells in South Carolina. The 

Coastal Plain study area includes all or parts of 46 counties 

in North Carolina and 26 counties in South Carolina. The 

wells selected for this report provide data to characterize 

ground-water levels and the hydraulic properties of the 

aquifers included in this investigation. Data included in the 

report are from field investigations and a compilation of 

published and unpublished well data. Well data for North 

Carolina were obtained from the North Carolina Division of 

Water Quality and Division of Water Resources, the North 

Carolina Geological Survey, and the USGS archives. Well data 

for South Carolina were obtained from the South Carolina 

Department of Natural Resources and Department of Health 

and Environmental Control and the USGS archives. The well 

descriptions include identifiers, well locations by latitude 

and longitude, land-surface elevations, well depths, open or 

screened intervals, well diameters, dates and depths of waterlevel measurements, aquifer assignments, and transmissivities 

of the aquifer. The data for each well are organized by county 

and state. The Coastal Plain aquifers presented in descending 

order from land surface are the surficial and Floridan aquifer 

systems, Tertiary Sand, Yorktown, Pungo River, Castle Hayne, 

Beaufort, Peedee, Black Creek, Middendorf, Cape Fear (upper 

and lower), and the Lower Cretaceous. Not all aquifers are 

present or recognized in both States. Wells completed in 

pre-Cretaceous crystalline bedrock are not included in this 

inventory. The ground-water data for this report are stored in 

the USGS Ground-Water Site Inventory System.

The authors appreciate the support and assistance 

provided by the personnel of the North Carolina Divisions 

of Water Quality and Water Resources of the Department 

of Environment and Natural Resources; the North Carolina 

Geological Survey; the South Carolina Land, Water, 

and Conservation Division of the Department of Natural 

Resources; and the South Carolina Department of Health and 

Environmental Control.
