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 QCW, 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.
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 1976 Quality Criteria for Water recommends the following:
50 ug/1 for domestic water supply (health);
0.01 times the 96-hour LC50 value, using the receiving or
comparable water as the diluent and soluble lead measurements
(using an 0.45 micron filter), for sensitive freshwater resident
species.
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be superseded.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.

All waters shall be maintained free of

this objective will be determined by use

Board.
The survival of aquatic life in surface
waters subjected to a waste discharge, or

shall not be less than that for the same

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-

The Division will use the EPA publication
entitled Quality Criteria for Water,
EPA-440/9-76-023 as guidance in establi-
shing case-by-case discharge limits for
pollutants not specifically listed in these
standards but included under the heading
"Other Constituents" in Regulation 3.4,
