INTRODUCTION
This digest is compiled to provide general information to the public as veil
as to Federal, State, and local officials. It contains excerpts from the
individual Federal-State water quality standards establishing pollutant
specific criteria for interstate surface waters. The water quality standards
program is implemented by the U. S. Environmental Protection Agency where
responsibility for providing water quality recommendations, approving
State-adopted standards for interstate waters, evaluating adherence to the
standards, and overseeing enforcement of standards compliance, has been
mandated by Congress.
Standards, a nationwide strategy for surface water quality management, contain
three major elements: the use (recreation, drinking water, fish and wildlife
propagation, industrial, or agricultural) to be made of the navigable water;
criteria to protect these uses; and an antidegradation statement to protect
existing high quality waters, from degradation by the addition of pollutants.
Guidance for the development of standards by individual States is contained in
two EPA documents entitled Water Quality Standards Handbook (1983) and Quality
Criteria for Water (1986).
Lead is not known to be beneficial or have nutritional value for any living
organism. However, it is toxic to man and other animals and has been shown to
accumulate in animal body tissues. Lead enters the aquatic environment
through precipitation, lead dust fallout, erosions and leaching of soil,
municipal and industrial waste discharge, and street runoff. The toxicity of
lead in water is affected by pH, hardness, organic materials, and the presence
of other metals.
The 1986 Quality Criteria for Water recommends the following:
Freshwater Aqu.t^g^^gJJftij^ggj:
c^onic :<1.273[ln(hardness)M.705)
Saltwater Aquatic Organisms and Their Uses:
acute 140 ug/1
chronic 5.6 ug/1
Human Health:
50 ug/1 drinking water standard
Since water quality standards are revised from time to time, following
procedures set forth in the Clean Water Act, individual entries in this digest
may be superseded. This digest will be updated periodically. Because this
publication is intended for use only as a general information reference, the
reader needs to refer to the current approved water quality standards to
obtain the latest information for special purposes and applications. These can
be obtained from the State water pollution control agencies or the EPA
Regional Offices.

Toxic materials shall not be present in receiving

which exceeds the acute toxicity. In no instance
shall the entire mixing zone be acutely toxic.

All waters shall be maintained free of toxic

The survival of aquatic life in surface waters
subjected to a waste discharge, or other controllable
water quality factors, shall not be less than that for
the same water body in areas unaffected by the waste
discharge, or when necessary for other control water
that is consistent with the requirements for

as stated in the previous sentence shall be evaluated
with a 96-hour bioassay.
In addition, effluent limits based upon acute
bioassays of effluents will be prescribed where
appropriate, additional numerical receiving water
objectives for specific toxicants will be established
as sufficient data become available, and source

data exists to define the mean hardness value at the
periodic low flow criteria, representative regional

where a regression analysis is not appropriate, a

The surface waters of the State which are designated

Toxic substances narrative: Assigning concentration
limits for the Fish and Wildlife Propagation
beneficial use is very complex. Limits are generally
assigned based upon laboratory bioassay work designed
to determine the 96-hour LC-0 for a particular aquatic
species. There are several physical, chemical and
biological problems which arise when attempts are made
to develop water quality standards based upon single
maximum concentration values. For this reason,
numerical concentration limits are developed in this
section for specified toxics. For toxics not
specified, or where data is not available in the
following table, concentrations for nonpersistent
toxic substances listed in Appendix C shall not exceed
0.1 of the 96-hour LC5Q for sensitive indigenous
species. Concentrations of persistent toxicants

listed in Appendix C shall not exceed 0.05 of the
96-hour LCeQ for sensitive indigenous species.
Concentrations of bioaccumulative toxicants listed in
Appendix C shall not exceed 0.01 of the 96-hour LC-Q
for sensitive indigenous species. Bioassay data for
Pimephales promelas (fathead minnow) and/or Lepomis
macrochirus (bluegill) shall be used in determining
compliance with the above criteria.
Due to interactions with water chemistry,
toxicity of some substances to aquatic organisms
varies across the State. Criteria for lead whose
toxicity is extremely dependent upon water ch'emistry
are listed by segment. The concentration varies from
32-166 ug/1 depending on the segment (see Oklahoma
Vater Quality Standards Table 1).
Toxicity to Aquatic Organisms: The surface waters of
the State outside the mixing zone but within the zone
of passage shall be maintained so that they will not
be toxic to fishes and other terrestrial and aquatic
life. Toxic substances in surface waters of the State
shall not be present in quantities which allow
significant bioaccumulation and/or biomagnification in
the food chain. If substances exhibit synergistic
effects when combined, toxicity tests described in
this section may be used to detect the increased
toxicity.
No toxicity shall be allowed downstream from the
mixing zone as determined by a forty-eight (48) hour
static test using appropriate laboratory animals
conducted in accordance with "Methods for Measuring
the Acute Toxicity of Effluents to Freshwater and
Marine Organisms," EPA-600/4-85-013 (Rev. March, 1985).
In addition, no toxicity shall be allowed as
measured using in-situ bioassay with sensitive
indigenous fishes ("An In-Situ Method for Evaluating
Acute Toxicity in Aquatic Environment." Noble
Foundation and Okla. Dept. Vldlf. Cons. Symposium on
Pond Mgt., Okla. City, Aug. 1985). In-situ testing
must be conducted over a period of ninety-six (96)
hours unless statistically significant differences in
mortality occur in a shorter period of time. Toxicity
of waters may be determined using statistical
differences for a total mortality between control and
presumed impact sites. Chronic toxicity shall not be
allowed in . waters of the State ("Methods for
Estimating the Chronic Toxicity of Effluents and
Receiving Waters to Freshwater Organisms,"
EPA-600/4-85-014). If significant mortality does not
occur at the. presumed impact site within ninety-six

Toxic substances narrative: The waters of the state
shall be managed so as to prevent the discharge of
radioactive or toxic wastes in concentrations,
quantities or combinations that may create a
significant likelihood of an adverse impact on human
health or acute or chronic toxicity to aquatic biota,
fish or wildlife. Unless otherwise specified by these
rules, the Secretary shall determine limits for
discharges containing radioactive or toxic wastes'
based on the results of biological toxicity
assessments and the appropriate available scientific
data, including but not limited to:
1. The current edition of the EPA publications
"Quality Criteria for Water" and the 1980 Ambient
Water Quality Criteria Documents ("White Books")
2. The Vermont State Health Regulation, Part 5,

In establishing such limits the Secretary shall
give consideration to the potential for
bioaccumulation as well as any antagonistic or
synergistic relationship that may exist between the
wastes being discharged and the concentration of other
wastes or constituents in the receiving waters. The
discharge of radioactive wastes shall not exceed the
lowest limits which are reasonably achievable.

Unless otherwise specified in these Standards, maximum

In those cases where maximum allowable

Wastewater or
other
methods approved by the EPA shall be used. The

applicable, as a test organism. Makeup water for the

The observed 96-hour LC50 is then to be multiplied by
an application factor, where established by EPA, to
determine the "safe" concentrations for the compound
in question. Where appropriate application factors
have not yet been established, the method for deriving
said application factor shall be that described in the
