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.

Zinc is an essential and beneficial element in animal and human metabolism at
moderately  low  concentrations.  It is usually found in  nature as a sulfide .and is
often associated with the sulfides  of other  metals.  Zinc is  used  in galvanizing
various iron and steel surfaces.  It  is also used to prepare alloys for dye casting.
Zinc will  impart a  bitter taste to water and therefore, it must be controlled in
domestic  water  supplies.  In natural waters, pH and other factors influence  the
solubility  of zinc and the resulting toxicity of the metal.

The 1976 Quality Criteria for Water recommends the following:

     5 mg/1 for domestic water supply (welfare).

     For freshwater aquatic life, 0.01 of the 96-hour LC50 as
     determined through bioassay using a sensitive 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
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

Toxic  substances  shall  not  exceed  the

water standards latest edition.

Not Specified

Toxic substances narrative: no waste sub-
stances containing chemical  constituents
which  would be harmful  to humans, ani-
mal or aquatic life.

Not specified

Toxic substances narrative:   at all  times
free from toxic substances attributable to
sewage, industrial waste, or  other  waste

aquatic life.

Not specified

Toxic  substances  narrative:   free  from

For each class, the most sensitive benefi-
cial uses are identified and minimum  cri-
teria   for  water  quality in  the   water
column are  established.   The minimum
criteria in Reg. 3.4 have been developed
by applying the criteria contained in the
EPA  publication  Quality  Criteria  for
Water  (EPA-440/9-76-023) to account for
local conditions including, but not limited
to:

(a) The characteristics of the biological
community

(b)    Temperature,  weather and   flow
characteristics, and

(c)  Synergistic and antagonistic effects
of combinations of pollutants.

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
