1 Except for the aquatic life
				  values for metals, the values given in this appendix refer to the total
				  (dissolved plus suspended) amount of each substance unless otherwise noted. For
				  the aquatic life values for metals, the values refer to the total recoverable
				  method for ambient metals analyses.
2 Based on two routes of exposure
				  - ingestion of contaminated aquatic organisms and drinking water.
3 Based on one route of exposure -
				  ingestion of contaminated aquatic organisms only.
4 Substance classified as a
				  carcinogen, with the value based on an incremental risk of one additional
				  instance of cancer in one million persons.
5 Chemicals which are not
				  individually classified as carcinogens but which are contained within a class
				  of chemicals, with carcinogenicity as the basis for the criteria derivation for
				  that class of chemicals; an individual carcinogenicity assessment for these
				  chemicals is pending.
6 Hardness dependent criteria.
				  Value given is an example only and is based on a CaCO3
				  hardness of 400 mg/l. Criteria for each case must be calculated using the
				  following formula:
For the Criterion Maximum Concentration (CMC):
Cadmium
CMC =
								e0.9789[ln (hardness)]-3.866
Chromum (III)
CMC =
								e0.8190[ln (hardness)] + 3.7256
Copper
CMC =
								e0.9422[ln (hardness)] - 1.7000
Lead
CMC =
								e1.2730[ln (hardness)] - 1.4600
Nickel
CMC =
								e0.8460[ln (hardness)] + 2.2550
Silver
CMC =
								e1.7200[ln (hardness)] - 6.5900
Zinc
CMC =
								e0.8473[ln (hardness)] + 0.8840
CMC = Criterion Maximum Concentration (acute exposure value)
				  The threshold value at or below which there should be no unacceptable effects
				  to freshwater aquatic organisms and their uses if the one-hour concentration
				  does not exceed that CMC value more than once every three years on the
				  average.
For the Criterion Continuous Concentration (CCC):
Cadmium
CCC =
								e0.7977[ln (hardness)]-3.909
Chromium (III)
CCC =
								e0.8190[ln (hardness)] + 0.6848
Copper
CCC =
								e0.8545[ln (hardness)] - 1.7020
Lead
CCC =
								e1.2730[ln (hardness)] - 4.7050
Nickel
CCC =
								e0.8460[ln (hardness)] + 0.0584
Silver
No CCC criterion for silver
Zinc
CCC =
								e0.8473[ln (hardness)] + 0.8840
CCC = Criterion Continuous Concentration (chronic exposure
				  value) The threshold value at or below which there should be no unacceptable
				  effects to freshwater aquatic organisms and their uses if the four-day
				  concentration does not exceed that CCC value more than once every three years
				  on the average.
7 Safe Drinking Water Act
				  (MCL).
8 Freshwater aquatic life criteria
				  for pentachlorophenol are expressed as a function of pH. Values displayed in
				  the table correspond to a pH of 7.8 and are calculated as follows:
CMC =exp [1.005 (pH) - 4.869] CCC = exp [1.005 (pH) -
				  5.134]
9 This criterion applies to total
				  arsenic.
10 This criterion applies to total
				  PCBs (i.e., the sum of all congener or all isomer or homolog or Arochlor
				  analyses).
11 This criterion applies to the
				  sum of alpha-endosulfan and beta-endosulfan.
12 This criterion applies to DDT
				  and its metabolites (i.e., the total concentration of DDT and its metabolites
				  should not exceed this value).
13 The nonylphenol criteria
				  address CAS numbers 84852-15-3 and 25154-52-3.
14 The criterion is for a total
				  measurement of 5 haloacetic acids, dichloroacetic acid, trichloroacetic acid,
				  monochloroacetic acid, bromoacetic acid, and dibromoacetic acid.
15 Hardness values shall be no
				  greater than 400 mg/l. For waters with hardness concentrations greater than 400
				  mg/l, the actual ambient hardness may be used where a site-specific water
				  effect ratio has been determined consistent with the environmental protection
				  agency's water effect ratio procedure.
16 The department will recognize
				  the biotic ligand model as an appropriate tool for developing site-specific
				  limits for copper as well as the water-effects ratio (WER)
				  method.
