Introduction
This digest was compiled to provide general information to the public as well as
to Federal, State, and local officials. It contains excerpts from the individual
State-Federal water quality standards establishing pollutant specific criteria for
navigable 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 navigable
waters, evaluating adherence to the standards, and overseeing enforcement of
standards compliance, has been mandated by Congress.
The standards program, a nationwide strategy for surface water quality
management, contains two major elements: the use (recreation, drinking water,
fish and wildlife propagation, industrial, or agricultural) to be made of the
navigable water; and criteria to protect these uses.
Water quality criteria (numerical or narrative specifications for physical,
chemical, temperature, and biological constituents) are stated in the July 1976
U.S. Environmental Protection Agency publication Quality Criteria for Water
(QCW), order # 055-001-01049-4, price $3.50, available from the Government
Printing Office, Washington, D. C. The 1976 CQW, commonly referred to as the
"Red Book," is the most current compilation of scientific information used by the
Agency as a basis for assessing water quality. This publication is subject to
periodic updating and revisions in light of new scientific and technical
information.
State Water Quality Standards contain a "four free froms" statement, in which
one of the "free froms" specifically refers to toxic substances. This statement is
essentially a comprehensive narrative standard. It is designed to protect any
stream use from detrimental toxic effects of unknown substances. The 1976
Quality Criteria for Water recommendation for this provision, which can be one
of several general provisions in State water quality standards, is:
All waters must be kept free from substances attributable to
wastewaters or other discharges that injure or are toxic or produce
adverse physiological responses in humans, animals or plants.
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be superseded.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 wat.ir pollution control agencies or the EPA Regional Offices.

Toxic Substances Narrative
Toxic substances shall be kept below
levels which are deleterious to human,
animal, plant or aquatic life, or in
amounts sufficient to interfere with the
beneficial use of the water. As a mini-
mum evaluation for the presence of toxic
substances, a water shall be evaluated by
use of a 96-hour bioassay, guided by the
docum ent Standard Methods for the
Examination of Water and Wastewater.
The survival of the test organisms shall
not be less than that in controls which
utilize appropriate experimental water.

Toxic materials attributable to municipal,
industrial, agricultural, or other waste
discharges, shall not be present in receiv-
ing waters in such quanitities as to be
toxic to human, animal, plant or aquatic
life or to interfere with the normal propa-
gation of aquatic life. For any toxicants,
concentrations in the receiving waters
after mixing shall not exceed 0.01 of the
96-hour TL , unless they can be shown to
be nonperslstant and noncumulative, and
to exhibit no synergistic interactions with
other waste or stream components. In no
case shall concentrations exceed 0.05 of
the 96-hour TLm.
All waters shall be maintained free of
toxic substances in concentrations that
are toxic to, or that produce detrimental
physiological responses in human, plant,
animal, or aquatic life. Compliance with
this objective will be determined by use
of indicator organisms, analyses of
species diversity, population density,
growth anomalies, bioassays of appro-
priate duration or other appropriate
methods as specified by the Regional
Board.
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 arees unaffected by the

other control water that is consistent
with the requirements for "experimental
water" as described in "Standard Methods
for the Examination of Water and Waste-
water", latest edition. As a minimum,
compliance with this objective as stated
in the previous sentence shall be evalu-
ated with a 96-hour bioassay.
In addition, effluent limits based upon
acute bioassays of effluents will be pre-
scribed where appropriate, additional
numerical receiving water objectives for
specific toxicants will be established as
sufficient data become available, and
source control of toxic substances will be
encouraged.
Substances attributable to human-induced
discharges not otherwise controlled by
permits, BMP's, or plans of operation
approved by the Division, shall not be
introduced into the waters of the State in
amounts, concentrations, or combinations
which are harmful to the beneficial uses
or toxic to humans, animals, plants, or
aquatic life.
Note 4. The waters shall be free from
chemical constituents in concentrations
or combinations which would be harmful
to human, animal or aquatic life for the
most sensitive and governing water use
class. Criteria for chemical constitutes
contained in the Quality Criteria for
Water (EPA) shall be considered and used
as guidance. In areas where fisheries are
the governing considerations and approved
limits have not been established, bio-
assays are necessary to establish limits on
toxic substances, the recommendations
for bioassay procedures contained in
"Standard Methods for the Examination of
Water and Wastewater" and the applica-
tion factors contained, in Quality Criteria
for Water (EPA) shall be considered. For
public drinking water supplies, the raw
water sources must be of such a quality

None in concentrations or combinations
which would be harmful to human, animal

times at all places: shall be free from
domestic, industrial, agricultural, or other
man-induced non-thermal components of
discharges which, alone or in combination
with other components of discharges
(whether thermal or non-thermal) are
acutely toxic; or are present in concen-
trations which are carcinogenic, muta-
genic, or teratogenic to human beings or
to significant locally occurring, wildlife
or aquatic species; or pose a serious dan-
ger to the public health, safety, or wel-
fare.
General criteria for toxic substances
(applied to all surface waters except
within zones of mixing): substances in
concentrations which injure, are chroni-
cally toxic to, or produce adverse physio-
logical or behavioral response in humans,
animals, or plants - none shall be present.
No material or substance in such concen-
tration that, after treatment, would

for biota significant to the indigenous
aquatic community.
Shall not exceed 0.1 of the 96-hour median

concentrate in the aquatic biota, and are
likely to be toxic on the basis of available
scientific evidence, shall be limited as
determined by the Board.

nonpersistent toxic materials exceeding
0.1 of the 96-hour TLm, where the bio-
assay is made using fish indigenous to the
receiving waters. For persistent toxi-

0.05 of the 96-hour TLm.
It shall be unlawful to discharge or place
