 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.

 Chromium is an elementjrarely found in natural waters. It has oxidation states
 ranging from Cr   to Cr  , of which  the trivalent form is most commonly found
 in nature.   Chromium   salts, primarily chromates and dichromates, are used
 extensively in metal finishing, textile, and leather tanning  industries.  They are
 also used in pigments, fungicides, and wood preservatives.

 Chromium has been shown to be an essential trace element  for humans even
 though it has been shown to be toxic in some instances.   Chromium has been
 found  to  produce  toxic  effects  in  aquatic  life  when  in  relatively  high
 concentrations.

 The 1976 Quality Criteria for Water recommends the following:

      50 ugA (total) for domestic water supply (health)
    100 ug/1 (total) for freshwater aquatic life.

 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

are toxic to, or that produce detrimental
physiological responses  in  human,  plant,

compliance with this objective as stated
in the previous sentence shall be evalu-

In addition,  effluent limits  based  upon
acute bioassays of effluents will be pre-

tituents 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

where fisheries are the governing conside-

established, bioassays  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 application 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 that  EPA limits as
defined by the Safe  Drinking Water Act
(PL 93-523), or state limits if more strin-
gent, for finished water can be met after
