Another potential source of increased
recharge is the capture of recharge that was
originally rejected because water levels were at
or near land surface.As the water table declines
in response to pumping,a storage capacity for
infiltration of water becomes available in the
unsaturated zone.As a result,some water that
previously was rejected as surface runoff can
recharge the aquifer and cause a net increase in
recharge.This source of water to pumping wells
is usually negligible,however,compared to other
sources.
In summary,estimation of the amount of
ground water that is available for use requires
consideration of two key elements.First,the use
of ground water and surface water must be evaluated
together on a systemwide basis.This evaluation
includes the amount of water available from
changes in ground-water recharge,from changes
in ground-water discharge,and from changes in
storage for different levels of water consumption.
Second,because any use of ground water changes
the subsurface and surface environment (that is,
the water must come from somewhere),the public
should determine the tradeoff between groundwater
use and changes to the environment and
set a threshold at which the level of change
becomes undesirable.This threshold can then be
used in conjunction with a systemwide analysis of
the ground-water and surface-water resources to
determine appropriate limits for consumptive use.
