                                    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

    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

 un-ionized ammonia = 1.2  (total  ammonia-N)/(H-10Pka~PH)

 pka = 0.0902 + 2730/(273.2 + T)

 T = temperature in C.

 For Maumee Bay/Toledo, Magee Marsh Area, Port Clinton,  Sandusky Bay,  Huron, Vermilion, Lorain, Rocky River/
 Cleveland Harbor, Fairport/Painesville, Ashtabula, Conneaut,  and Mentor, the value is 0.05 mg/L.  For the
 rest of Lake Erie, the value is  0.025 mg/L.  Under no circumstances should ammonia-N concentrations exceed
 6.5 mg/L in Lake Erie and 13 mg/L in the excepted areas.

 has a 1,500 yg/L standard for total ammonia nitrogen.  Monthly average for Lake Michigan and Inner, Gary
 and Burns Harbours are respectively, 20.0 and 30.0 yg/L.

eThe maximum total ammonia nitrogen concentration at all times could be less than or equal to the numerical
 value given by the following equation depending upon which is less:

 un-ionized ammonia nitrogen (NH3-N)x(log~x[pK-r-pH]-fl),  where:

1.5  ARSENIC (mg/L)


aWhen used for irrigation,  it depends on  soil  type and crop.  0.1 mg/L-applies to sensitive crop  and  sandy
 loam; 1.0 mg/L-applies to  sensitive crop and  clay; 1.0 mg/L-applies to tolerant crop and sandy loam;  2.0
 mg/L-applies to tolerant crop and clay.   For  livestock watering the recommended objective is 0.5 mg/L.

^Trivalent arsenic.   At 10~6 risk of cancer.

cThe recommended criteria for livestock watering  is 0.2 mg/L.   Irrigation waters, when continuously used,
 should not exceed 0.1  mg/L or 2.0 mg/L when used up to 20 years on fine textured soils of pH 6.0-8.5.

dThe standard in Lake Superior is 0.01 mg/L, except for Superior Bay where  it is 0.05 mg/L.

eDoes not apply to Indiana  Harbor.

^0.1 mg/L applies to the irrigation of crops,  while 0.2 mg/L applies to livestock watering.

^Applies to one-hour average trivalent arsenic concentration which should not be exceeded more than once
 every three years on the average.  The four-day  arsenic  (III)  concentration of 0.19 mg/L should  not  have
 exceeded more than once every three years on  the average.

aHardness dependent.   The one-hour average  concentration should not be exceeded once every three  years  on
 the average and is determined  by the following  equation = e exp (1.128  [In  (hardness)] - 3.828.   For example,
 at 50 mg/L CaC03,  the criteria is 1.8 yg/L;  at  100 mg/L CaC03 it is 3.9 yg/L and at 200 mg/L
 CaC03, the value is 8.6 yg/L.   The four-day  average concentration which should not be exceeded more
 than once in three years on the average  is determined by the following  equation - e exp (0.7852  [In
 (hardness)] - 3.490.  For example, at hardness  of 50, 100, and 200 mg/L as  CaCOa, the concentrations
 respectively are 0.66, 1.1, and 2.0 yg/L.

2.69  TOXIC SUBSTANCES


aFree from substances attributable to wastewaters or other discharges  that  injure  or are toxic or produce
 adverse physiological responses in humans, animals or plants.

bAll pollutants or combinations of pollutants shall not exceed,  at any time,  one-tenth  of the 96-hour median
 tolerance limit (TLm) of LCSO for any representative aquatic species.  Pollutants or combinations of
 pollutants which are known to be persistent toxicants in the aquatic  environment  shall not exceed, at any
 time, an application factor of one one-hundreth applied to the  96-hour TLm of  LCSQ.

cNone in amounts that will interfere with use for primary contact recreation  or will  be injurious to the
 growth and propogation of fish or which in any manner adversely affect the flavour,  colour or odour of water.

^Should not be in concentrations or combinations which are of a  public health significance, nor  be present
 in amounts which are acutely harmful to animal, plant or aquatic life.

eShall not be present in the waters of the state at levels which are or may become injurious to  the public
 health, safety, or welfare; plant and animal life; or the designated  uses  of those waters.

f Shall not exceed one-tenth of 96-hour median tolerance limit except U.S. EPA registered pesticides approved
 for aquatic application.

90.1 x 96-hour LC50.

n0.005 x 96-hour LCSO for unspecified toxic substances.

ipor non-persistent compounds or mixtures with no specific objective,  this  concentration should  not exceed
 0.05 x 96-hour LCS0.

JNone at levels harmful either directly or indirectly for the protection of wildlife or livestock.

^Concentrations in water or aquatic organisms should be substantially  absent  or less than detection limits
 as determined by the best scientific methodology available.  For the  protection of wildlife or  livestock,
 levels should not be harmful, either directly or indirectly.
     exceed one-half of the 96-hour median tolerance limit (96-hour TLm).

""Non-cumulative pollutants shall not exceed 0.05 x 96-hour LC50.

5.3  HARDNESS (mg/L)


aA maximum acceptable level has not been established since public  acceptance  varies  considerably according
 to local conditions.  Dependency upon pH and  alkalinity, hardness  levels  between 80  and  100 mg/L  (as
 CaC03) are considered to provide an acceptable balance between corrosion and incrustation of pipes.
 Water supplies with a hardness greater than 200 mg/L are considered poor but tolerable; those  in excess of
 500 mg/L are unacceptable for most domestic purposes.

textiles - 120 mg/L; Pulp and Paper - 475 mg/L; Petroleum - 900 mg/L;  Chemical  and  Primary Metals  - 1,000
 mg/L; and Electric Utilities - 5,000 mg/L.

C50 mg/L applies to Lake Superior except for Superior Bay where the  value is  250 mg/L.

^Does not apply to Lake Erie or nearshore waters.

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
                                                     - 379 -

 width, (c) mixing zone characteristics shall not be lethal to aquatic organisms,  (d)  for contaminants other
 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 59F
 (15C) 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;

At least 90% of the volume of the mixing zone shall not exceed at any time the 24 to 96-hour median tolerance
limit (TLm) or LC50 for any representative aquatic species, as determined from existing scientific
literature or the 96-hour median tolerance limit (TLm) or LCSO for any representative aquatic  species,
as determined by static bioassays for persistent toxicants and dynamic bioassays for non-persistent toxicants.

 cannot be uniformly prescribed, but shall be based on such factors as effluent quality and quantity,
 available dilution, temperature, current, type of outfall, channel configuration and restrictions to fish
 movement.  As a guide to the delineation of a mixing zone, the following shall be taken into consideration:

    1.   Limiting mixing zones to as small an area as practicable, and conforming to the time exposure
         responses of aquatic life.

    2.   Providing passageways in rivers for fish and other mobile aquatic organisms.

    3.   Where possible, mixing zones being no larger than 25% of the cross-sectional area or volume of flow
         of the stream and not extending more than SOX of the width.

    4.   For contaminants other than heat, the 96-hour TL,,, to indigenous fish and fishfood organisms not
         being exceeded at any point in the mixing zone.

    5.   Mixing zones not exceeding 10% of a lake's total surface area.

    6.   Mixing zones not interfering with spawning or nursery areas, migratory routes, nor mouths of
         tributary streams.

    7.   Mixing zones not overlapping, but where they do, taking measures to prevent adverse synergistic
         effects.

   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 3F 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:

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.

-------
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.

5.11  TEMPERATURE (C)


aFor drinking water

^No change that would adversely affect any local or general  use of  the waters.

cNatural thermal regime shall not be altered so as to impair the quality of  natural  environment.
 Particularly, the diversity, distribution and abundance of  plant and animal  life shall  not be significantly
 changed.  The temperature at the edge of the mixing zone shall not exceed the  natural ambient water by more
 than 10C (18F).  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  30C
 (86F) or the temperature at a representative control location plus 10C (18F)  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.

 b =     slope of the line fitted to experimental data which are available for  some  species from Appendix
         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 2C 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
 between the ultimate upper incipient lethal temperature and the optimum temperature for the most sensitive
 important species (and appropriate life state) that normally is found at that  location  and time; or during
 reproductive seasons (generally April through June and September through October) should meet site-specific
 requirements for successful migration, spawning, egg incubation, fry rearing,  and other reproductive
 functions of important species.  These local requirements should supersede  all other requirements when  they
 are applicable; or is a site-specific limit that is fund necessary to preserve normal species diversity or
 prevent appearance of nuisance organisms.

eAll sources of heated effluents in existence as of January 1, 1971 shall meet  the followig restrictions
 outside of a mixing zone which shall be no greater than a circle with a radius of 1,000 feet or an equal
 fixed area of simple form:

   (11)      The normal dally and seasonal temperature fluctuations that existed before the addition of heat
             shall be maintained.

   (111)     The maximum temperature rise at any time above natural temperatures shall  not exceed 1.7C
             (3F).  In addition, the water temperature shall not exceed the maximum limits Indicated 1n the

      (11)   No heated effluent shall affect spawning grounds or fish migration routes.

      (111)  Discharge structures shall be so designed as to maximize short-term mixing and thus  to reduce
             the area significantly raised 1n temperature.

      (1v)   No discharge shall exceed ambient temperatures by more than 11C (20F).

      (v)    Heated effluents from more than one source shall not Interact.

      (v1)   All reasonable steps shall be taken to reduce the number of organisms drawn Into or  against the
             Intake.
