Ground-water level data for North
Carolina, 1988-90
Open-File Report 92-57
By A.G. Strickland and others
Abstract
Continuous and periodic water-level measurements were made in 59
key wells throughout North Carolina. Additional measurements
were made in 112 supplementary wells completed in Coastal Plain
aquifers of the State. Changes in groundwater storage are shown
in 3-year and 10-year hydrographs of selected wells in the
State. The water table in the shallow aquifers was higher
throughout most of 1989 and early 1990 than in 1988, indicating
that these aquifers were sufficiently recharged by precipitation
to replenish the late 1987-88 deficit in groundwater storage.
Water levels in the heavily pumped Coastal Plain aquifers
declined as a result of water being withdrawn from aquifer
storage. Record low water levels were measured in 8 to 13 wells
completed in the Castle Hayne aquifer and in 6 of 8 wells in the
Peedee aquifer; the maximum annual declines during 1988-90
averaged 3.3 and 1.6 ft/yr, respectively, for these two
aquifers. All wells in the Black Creek, upper Cape Fear, and
lower Cape Fear aquifers had record low water levels during
1988-90, with maximum annual declines averaging 9.0, 2.2, and
2.6 ft/yr, respectively. Water levels in two of three wells in
the Yorktown aquifer did not show a general downward trend
during 1988-90, although water levels declined in the third
well, reaching a record low in 1990. The effects of water
withdrawals from major pumping centers in the North Carolina
Coastal Plain are shown in potentiometric-surface maps of the
Black Creek and lower Cape Fear aquifers.
