(1) Class GA groundwaters; usage and occurrence:
(a) Best
Usage. Existing or potential source of drinking water supply for
humans.
(b) Conditions Related to
Best Usage. This class is intended for those groundwaters in which chloride
concentrations are equal to or less than 250 mg/l, and which are considered
suitable for drinking in their natural state, but which may require treatment
to improve quality related to natural conditions.
(c) Occurrence. In the saturated
zone.
(2) Class GSA groundwaters; usage and occurrence:
(a) Best
Usage. Existing or potential source of water supply for potable mineral water
and conversion to fresh waters.
(b)
Conditions Related to Best Usage. This class is intended for those groundwaters
in which the chloride concentrations due to natural conditions is in excess of
250 mg/l, but which otherwise may be considered suitable for use as potable
water after treatment to reduce concentrations of naturally occurring
substances.
(c) Occurrence. In the
saturated zone.
(3) Class GC groundwaters: usage and occurrence:
(a) Best Usage. The best usage of GC
groundwaters is as a source of water supply for purposes other than drinking,
including other domestic uses by humans.
(b) Conditions Related to Best Usage. This
class includes those groundwaters that do not meet the quality criteria for GA
or GSA groundwaters and for which efforts to improve groundwater quality would
not be technologically feasible, or not in the best interest of the public.
Continued consumption of waters of this class by humans could result in adverse
health affects.
(c) Occurrence.
Groundwaters of this class may be defined by the Commission pursuant to Section
.0300 of this Subchapter on a case by case basis.
