PREAMBLE
This document 1s a compendium of water quality objectives, criteria,
guidelines, and standards applicable to the Great Lakes. These Include the
water quality objectives of the Great Lakes Water Quality Agreement (1978),
the criteria and guidelines established by the Governments of Canada and the
United States, water quality standards of the eight Great Lakes states, and
the water quality objectives of the Province of Ontario. Each
criteria/standards for chemical constituents or other parameters are presented
1n terms of the use being protected. While the primary focus of this report
1s those water quality criteria/standards applicable to the Great Lakes,
others are presented according to use being protected.
The following definitions are used 1n this report to distinguish among
objectives, criteria, guidelines and standards which should not be used
Interchangeably:
Objective - A designated concentration of a constltutent that when not
exceeded, will protect an organism, a community of organisms, a
prescribed water use, or a designated multiple-purpose water use
with an adequate degree of safety. It 1s based on scientific
concentration-effect relationship Information and when applied
to multiple-purpose use water bodies, may be required to reflect
prevailing local natural conditions, or social and economic
factors, or an additional degree of safety to particularly
sensitive ecosystems.
(Environment Canada, 1979, Guidelines for
Surface Water Quality. Vol. 1. Inorganic
Chemical Substances).
x1
-------
Criterion -
A designated concentration of a constituent, based on scientific
judgements, that, when not exceeded will protect an organism, a
community of organisms, or a prescribed water use with an
adequate degree of safety.
(Ontario Ministry of the Environment, 1984,
Water Management-Goals. Policies, and
Implementation Procedures).
Guideline -
A numerical concentration limit or narrative statement
recommended to support and maintain a designated water use.
(Canadian Council of Resource and
Environment Ministers, 1985, Inventory of
Water Quality Guidelines and Objectives.
1984).
Standard - An objective that 1s recognized 1n enforceable environmental
control laws of a level of government.
(Canadian Council of Resource and
Environment Ministers, 1985, Inventory of
Water Quality Guidelines and Objectives.
1984).
A water quality criterion may be used as the basis for
regulation or enforcement, but the standard may differ from a
criterion because of local natural conditions, such as naturally
occurring organic acids, or because of the Importance of a
particular waterway, economic considerations, or the degree of
safety to a particular ecosystem that may be desired,
(U.S. Environmental Protection Agency, 1976,
Quality Criteria for Mater).
The designated uses to be protected that are utilized 1n this compendium
Include: general, domestic, aquatic habitat, agriculture, recreation and
-------
aesthetics, and Industrial. Constituent values appearing under the general
use category, for the roost part, will protect all uses of the Great Lakes. In
some cases, however, values were placed 1n the general category when the use
to be protected was not specified.
The domestic use protection category appearing 1n the compendium generally
refers to the protection of public water supplies after some degree of
treatment. Exceptions are the Environment Canada guidelines which refer to
the raw public water supplies prior to treatment unless otherwise stated. In
the States of Wisconsin, Indiana, and Pennsylvania, the public water supply
standard must be met at the point of water Intake or withdrawal. The United
States Environmental Protection Agency (U.S. EPA) criteria (taken from Ref. #
3) refers to the protection of human health when Ingesting both contaminated
aquatic organisms and ambient water. If the chemical 1s carcinogenic,
exposure results 1n an Incremental Increase of cancer risk over a lifetime by
10"6.
The agricultural use protection category applies to water used for both
livestock watering and Irrigation, unless otherwise Indicated.
Public water supply standards/criteria may also appear under the
recreation and aesthetics category. Such criteria/standards only Indirectly
affect human health and, for the most part, Include physical characteristics
of water such as colour, odour, taste, temperature, and turbidity. Recreation
Includes swimming and bathing uses of water be it total or partial body
contact.
The Industrial use protection category for the States of Illinois and New
York, and Environment Canada apply only to industrial use of water in food
processing. For the States of Indiana, Michigan, and Minnesota, this use
category applies to industries using water for cooling and/or non-food related
processes.
A summary of the use designation protection category(s) applicable to a
given Great Lake by state jurisdiction is provided in Table 1. It should be
noted that not all of the derived values for some of the State Water Quality
xiii
-------
Standards necessarily apply to a given Great Lake. In some cases the values
are only applicable to tributary waters that have a particular designated use.

b60X of total cations as milliequivalents per liter for irrigation purposes.
cln irrigation water may be a problem in the soil solution as a component of total salinity. The sodium
adsorption ratio (SAR) 1s an expression of the amount of sodium adsorbed on the soil:
SAR - Na+ / / (Ca*+ + Mg+*)/2
where the cations are expressed in meq/L. SAR values of less than 4 will not create toxicity problems for
foliar absorption. For less sensitive crops, values of up to 6 or 7 can be used. However, higher SAR
values may cause a reduction in soil permeability and should be avoided.

5.4 MIXING ZONES
aAn area contiguous to a discharge where receiving water quality may meet neither all quality criteria nor
requirements otherwise applicable to the receiving waters. The 96-hour LCSO for biota significant to the
indigenous aquatic community should not be exceeded, and should be free of effluent substances that will
settle to form objectionable deposits or from effluent-associated materials that float to form unsightly
masses or produce objectionable colour, odour or turbidity. Such zones should be located in a manner that
they do not form a barrier to migratory aquatic species. As a good practice, the combined areas of all
mixing zones within a lake should not exceed 10/K of the lake surface area. Shorelines should be discouraged
in preference to deep water for waste activities. The relative social and ecological values of the aquatic
life that may inhabit a particular waterway area should be given due consideration in zone definition along
with biological, chemical and physical appraisals.
size of the mixing zone cannot be uniformally prescribed. The governing principle is that the
proportion of any body of water or segment thereof within mixing zones must be quite small if the water
quality standards are to have any meaning. This principle shall be applied on a case-by-case basis to ensure
that neither any individual source nor the aggregate of sources shall cause excessive zones to exceed the
standards. The water quality standards must be met in the bulk of the body of water, and no body of water
may be used totally as a mixing zone for a single outfall or combination of outfalls. Moreover, except as
otherwise provided in this chapter, no single mixing zone shall exceed the area of a circle with a radius of
183 m. (600 feet). Single sources of effluents which have more than one outfall shall be limited to a total
mixing area no larger than that allowable if a single outfall were used.
In determining the size of the mixing zone for any discharge, the following must be considered:
1 . The character of the body of water;
2. The present and anticipated future use of the body of water;
3. The present and anticipated water quality of the body of water;
4. The effect of the discharge on the present and anticipated future water quality;
5. The dilution ratio; and
6. The nature of the contaminant.
In addition to the above, the mixing zone shall be so designed as to assure a reasonable zone of passage for
aquatic life in which the water quality standards are met. The mixing zone shall not intersect any area of
any such waters in such a manner that the maintenance of aquatic life in the body of water as a whole would
be adversely affected, nor shall any mixing zone contain more than 25% of the cross-sectional area or volume
of flow of a stream except for those streams where the dilution ratio is less than 3:1.
- 378 -
-------
Temperature standards contain additional requirements fo heated discharges. The mixing zone shall be no
greater than a circle with a radius of 305 m. (1,000 ft.) or an equal fixed area of simple form.
cThe mixing zone shall be considered a place where waste and receiving waters mix and not as a place where
effluents are treated. All mixing zones will be determined on a case-by-case basis by the Indiana Stream
Pollution Control Board after consideration of the following:
1. the dilution ratio;
2. the physical, chemical, and biological characteristics of the receiving body of water;
3. the physical, chemical, and biological characteristics of the waste effluent;
4. the present and anticipated uses of the receiving body of water;
5. the existence of an impact upon any spawning nursery areas of any indigenous aquatic species; and
6. the synergistic effects or overlapping mixing zones or the aggregate effects of adjacent mixing
zones.
For the Indiana Harbor Ship Canal, a universal mixing zone cannot be prescribed because of varying physical,
chemical, and biological conditions. In addition to the above conditions, the following information is
required:
1. the measured or anticipated effect of the discharge on the quality of the receiving body of
water;
2. any obstruction of migratory routes of any indigenous aquatic species; and
3. wherever possible, the mixing zone should be limited to no more than 1/4 (25%) of the
cross-sectional area and/or volume of flow of stream leaving at least 3/4 (75%) free as a zone
of passage for aquatic biota nor should it extend over 1/2 (50%) of the width of the stream.
^Shall be determined on a case-by-case basis.
eMeans for expediting mixing and dispersion of sewage, industrial waste, or other waste effluents in the
receiving interstate waters are to be provided so far as practicable when deemed necessary by the agency to
maintain the quality of the receiving interstate waters in accordance with applicable standards. Mixing
zones can be established by the agency on an individual basis, with primary consideration being given to the
following guidelines: (a) mixing zones in rivers shall permit an acceptable passageway for the movement of
fish, (b) the total mixing zone or zones at any transect of the stream should contain no more than 25% of the
cross-sectional area and/or volume of flow of the stream, and should not extend over more than 50% of the

than heat, the 96-hour median tolerance limit for indigenous fish and fishfood organisms should not be
exceeded at any point in the mixing zone, (e) mixing zones should be as small as possible, and not intersect
spawning or nursery area, migratory routes, water intakes, nor mouths of rivers, and (f) overlapping of
mixing zones should be minimized and measures taken to prevent diverse synergistic effects.
department shall specify definable, numerical limits for all mixing zones (e.g. linear distances from
the point of discharge, surface area involvement, or volume or receiving water entrained in the thermal
plume). Conditions in the mixing zone shall not be lethal in contravention of water quality standards to
aquatic biota which may enter the zone. The location of mixing zones for thermal discharges shall not
interfere with spawning areas, nursery areas and fish migration routes.
9por Lake Erie, no mixing zone shall:
(i) interdict the mouth of a stream, thereby blocking any portion of it; or
(ii) interdict the migratory routes or interfere with natural movements, survival, reproduction,
growth, or increase the vulnerability to predation of any representative aquatic species; or
(111) include spawning or nursery areas of any representative aquatic species; or
(iv) include a public water supply intake; or
(v) include any bathing area where bath houses and/or lifeguards are provided;
(vi) contact the shoreline, whenever such contact can be avoided.
The zone which is physically inhabitable by aquatic life shall not exceed, at any time, the 48 to 96-hour
LCSO for any representative aquatic species, as determined by static bioassays for persistent toxicants
and dynamic bioassays for non-persistent toxicants
A thermal mixing zone to permit dilution and cooling of a waste heat discharge shall be considered a region
in which organism response to temperature is time-dependent. Exposure to temperatures in a thermal mixing
zone shall not cause an irreversible response which results in deleterious effects to the wildlife and
aquatic life representative of the receiving waters. The daily average temperature in a thermal mixing zone
at the point nearest to the discharge that is accessible to the resident aquatic organisms shall not exceed
the temperatures listed in Table 1 at the corresponding ambient temperature. At ambient temperatures of 59°F
(15°C) and above, the daily average temperature in a thermal mixing zone will be determined on a case-by-case
basis. Thermal mixing zone size limitations shall also be established on a case-by-case basis for all point
source discharges subject to permit. No thermal mixing zone shall:
(i) interdict the migratory routes or interfere with natural movements, survival, reproduction,
growth, or increase the vulnerability to predation of any representative aquatic species;
(ii) interfere with or prevent the recovery of an aquatic community or species population that
could reasonably be expected as previously limiting water quality conditions improve;

8. Restricting the pH values greater than 4.0 s.u. and to values less than 11.0 s.u. at any point in the
mixing zone for the protection of indigenous fish and fishfood organisms.
For Lake Michigan and Lake Superior, the following thermal standards are established so as to minimize
effects on the aquatic biota in the receiving waters.
1. Thermal discharges shall not raise the receiving water temperature more than 3°F above the existing
natural temperature at the boundary of mixing zones established in paragraphs (b) and (c).
2. The mixing zone for a shoreline thermal discharge shall be the area included within the perimeter of
a rectangular figure extending 1,250 feet in both directions along the shoreline from the outfall and
1,250 feet into the lake.
3. The mixing zone for an offshore thermal discharge shall be the area within a 1,000 foot radius circle
with Its center at the point of discharge.
4. The department may, upon request from the owner of a source of thermal discharge, adjust the
boundaries of the mixing zones established in paragraph (b) for that source. In no case may any
mixing zone so established Include an area greater than 72 acres nor may it include more than 2,800
feet of shoreline.
In addition to the.limitation set forth in the subsections above, but excepting the Milwaukee Harbor,
Port Washington Harbor and the mouth .of the Fox River, thermal discharges to Lake Michigan shall not
raise the temperature of the receiving waters at the boundary of the established mixing zone above
the following limits:
January 45°F July 80°
February 45° August 80°
March 45° September 80°
April 55° October 65°
May 60° November 60°
June 70° December 50°
- 385 -
-------
A mixing zone may not be used as an alternate to adequate treatment. The mixing zone dimensions will be
kept as small as possible while ensuring that the Provincial Water Quality Objectives are met at the boundary
of the mixing zone.
1. Mixing zones should not contain:
materials which form objectionable deposits, i.e. scums, oil or floating debris;
substances producing objectionable colour, odour, taste or turbidity;
substances which produce objectionable growths of nuisance plants and animals;
substances which render the mixing zone aesthetically unacceptable.
2. The presence of a mixing zone should in no way pose a threat to the species survival of any organism
in the receiving water outside the mixing zone.
3. No conditions within the mixing zone should be permitted which:
a) are rapidly lethal to important aquatic life (resulting in conditions which result in sudden
fish kills and mortality of organisms passing through the mixing zones); or
b) cause irreversible responses which could result in detrimental post-exposure effects; or
c) result in bioconcentration of toxic materials which are harmful to the organism or its consumer;
or
d) attract organisms to the mixing zones, resulting in a prolonged and lethal exposure period.
4. A mixing zone shall not be allowed to create a barrier in a prolonged and lethal exposure period.
5. Rapid changes in the water quality which could kill organisms by shock effects must not be present.
Such conditions could have the effect of creating a higher toxicity value.
6. Municipal and other water supply intakes and recreational areas, as a general rule, should not lie
within a mixing zone. However, knowledge of the effluent characteristics and the type of discharge
associated with the mixing zone could allow such a mixture of uses.
7. Mixing zones may overlap unless the combined effects exceed the conditions specified in these mixing
zone guidelines.
- 386 -
-------
8. Limitations on mixing zones should be established by the Ministry on a case-by-case basis, where
"case" refers to both local considerations and the waterbody as a whole or segments of the waterbody.
9. Existing biological, chemical, physlcl and hydrologlcal conditions should be known when considering
the location of a new mixing zone or limitations on an existing one.
10. The design and location of the outfall should be considered on a case-by-case basis to reduce the
Impact of the mixing zone on the receiving waters.
11. Total loadings Into all the mixing zones within a river, lake or segment thereof, must not exceed the
acceptable loadings from all point-source discharges required to maintain satisfactory water quality.

Particularly, the diversity, distribution and abundance of plant and animal life shall not be significantly

than 10°C (18°F). Under special circumstances, local condition may require even lower temperature
differences. The maximum temperature of the receiving water outside the mixing zone shall not exceed 30°C
(86°F) or the temperature at a representative control location plus 10°C (18°F) or the allowed temperature
difference, whichever is less.
^Maximum temperature for short exposures is time-dependent and is given by the species-specific equation:
Temperature (°C) = l/b[log10(time in minutes)-a]-2
Where:
a = Intercept on the "y" or logarithmic axis of the line fitted to experimental data which are available
for some species from Appendix 1I-C, NAS, 1974.

Il-C, NAS, 1974.
Weekly average temperature in the cooler months (mid-October to mid-April) should protect against mortality
of important species if the elevated plume temperature is suddenly dropped to the ambient temperature, with
the limit being the acclimation temperature minus 2°C when the lower lethal threshold temperature equals the
ambient water temperature; or in the warmer months (April through October) it is determined by adding to the
physiological optimum temperature (usually for growth) a factor calculated as one-third of the difference
