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.

Mercury is an element which is not biologically essential  or  beneficial.  It has
been  detected  in  unpolluted rivers.    However,  toxic  levels are  generally
attributed to  mining and  agricultural activities, and to a larger extent waste
discharges from wood processing facilities.  Mercury can exist in several forms
ranging  from  elemental  to  dissolved inorganic  and  organic species.   Special
significance is given to elemental  mercury since it can  be  metabolically and
biochemically converted into highly toxic  organomercurie complexes.  Several
of the mercury  species also have a high  bioconcentrating factor in  the aquatic
environment  and  considerations must  be  given  to the  food  chain transport
resulting in human consumption of contaminated  fish.

The 1976 Quality Criteria for  Water recommends the following:

     20 ug/l(total)    for domestic water supply (health);
     0.05 ug/1 (total)  for freshwater aquatic life and wildlife;
     0.10 ug/1 (total)  for marine 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.

Criteria in mg/1

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  areas unaffected  by the
waste discharge, or when  necessary for
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

chemical  constitutes  contained  in the

considered and used as guidance.  In areas
where fisheries are the governing conside-

defined by the  Safe  Drinking Water Act
(PL 93-523), or state limits if more strin-

conventional treatment.

Toxic substances narrative:  None in con-

any other uses. (See Note 4. above).

less, at the  request of the Environmental

Compliance  with Section  VLB.  of these
