A.
PUBLIC WATER SUPPLY
				CLASSIFICATION
:
Waters in this classification are a source of raw water
				  supply for drinking and food processing purposes. The water treatment process
				  shall be approved by the Mississippi State Department of Health. The raw water
				  supply shall be such that after the approved treatment process, it will satisfy
				  the regulations established pursuant to Section 1412 of the Public Health
				  Service Act as amended by the Safe Drinking Water Act (
				  42
				  U.S.C. §§
											300f to
				  300j-27
				  ). Information regarding surface water intakes for Public Water Supply is
				  provided in Table 3.

Waters that meet the Public Water Supply criteria shall also
				  be suitable for secondary contact recreation. Secondary contact recreation is
				  defined as incidental contact with the water during activities such as wading,
				  fishing, and boating, that are not likely to result in full body immersion. In
				  considering the acceptability of a proposed site for the discharge of
				  wastewater in or near waters with the Public Water Supply Classification, the
				  Permit Board shall consider the relative proximity of the discharge to water
				  supply intakes.
(1)
Bacteria
:
				Culturable e.coli shall not exceed a geometric mean of 126 per 100 ml over a
				30-day period, nor shall the samples examined during a 30-day period exceed 410
				per 100 ml more than 10% of the time. There should be a minimum of 5 samples
				taken over a 30-day period with no less than 12 hours between individual
				samples.
(2)
Chlorides
				(Cl )
: There shall be no substances added which will cause the
				chloride content to exceed 230 mg/l in freshwater streams.
(3)
Specific
				Conductance
: There shall be no substances added to increase the
				conductivity above 500 micromhos/cm for freshwater streams.
(4)
Total Dissolved
				Solids
: There shall be no substances added to the waters that will
				cause the dissolved solids to exceed 500 mg/l for freshwater streams.
(5)
Threshold Odor
:
				There shall be no substances added which will cause the threshold odor number
				to exceed 24 (at 60° C) as a daily average.
(6)
Radioactive
				Substances
: There shall be no radioactive substances added to the
				waters which will cause the gross beta activity (in the known absence of
				Strontium-90 and alpha emitters) to exceed 1000 picocuries per liter at any
				time.
(7)
Specific
				Chemical Constituents
: In addition to the provisions in Section
				2.2.A.4, the following concentrations
