2l Current and Potential Sources of Drinking Water are all
other aquifers that are currently used, or potentially
available for drinking water; and

3l Aquifers Not Considered Potential Sources of Drinking
Water are sources of ground water that are saline.or
otherwise contaminated beyond reasonable use as drinking
water.

EPA will. accord different levels of protection to each class.
for example:

EPA will discourage and seek to develop regulations
banning the siting of hazardous waste facilities over
special Aquifers (Class I). further, Agency policy
will be directed toward restricting or banning the use
of those pesticides which are a particular problem in
ground water. EPA's policy for cleanup will be the
most stringent in these areas.

for ground water which is a current and potential source
of drinking water (Class III current protection and
cleanup policies will continue to apply. In addition,
where aquifers are vulnerable and used as a current
source of drinking water, EPA will ban the siting of
hazardous waste facilities. While EPA's cleanup policy
will require clean-up to drinking water quality or
equivalent levels, exemptions will be available to
allow a less stringent level for ground water which is
a potential source of drinking water, but is unlikely
to be used for that purpose.

For aquifers which are not considered potential sources
of drinking water (Class III), EPA will require protec-
tive measures to assure that there is no migration to
Class I and II ground waters, and to prevent a discharge
to surface water that could adversely affect human
health or the environment. Technology standards for
hazardous waste facilities would be the same as for
Class I and Class II. With respect to cleanup, should
the hazardous waste facility leak, waivers establiShing
less stringent concentration limits would be considered
on a case-by-case basis. Waivers would not be available,
however, when a private facility caused the contamina-
tion that precluded future use. EPA's Superfund program
will not focus its activities on protecting or improving
ground water that has no potential impact on human health
and the environment.
