INTRODUCTION
This digest is compiled to provide general information to the public as well as to
Federal, State,  and  local  officials.   It  contains  excerpts from the individual
Federal-State water  quality standards establishing pollutant specific  criteria for
interstate 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 interstate
waters, evaluating adherence  to the standards, and  overseeing  enforcement of
standards compliance, has been mandated by Congress.

Standards,  a nationwide strategy for  surface  water quality management, contain
three major  elements:  the use  (recreation,  drinking  water,  fish  and  wildlife
propagation,  industrial,  or agricultural) to be made of the navigable water; criteria
to protect  these uses; and  an antidegradation statement to protect existing high
quality waters, from degradation by the addition of pollutants.

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),
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.

Criteria  for  phosphorus in  State  water quality  standards are the subject of  this
digest.  Phosphorus criteria for water are established to provide a threshold level
which  when  exceeded  would most likely result in aquatic life  toxicity, due to
elemental phosphorus, and  excessive  aquatic  plant  growth, caused by phosphate
phosphorus which is an essential plant  nutrient.  Phosphorus and  phosphates usually
enter a  waterbody  from  land  runoff,  human  and  animal  excretia,   decaying
vegetation, and  industrial processes and detergents.  Once combined with  other
nutrients in a waterbody, their  removal becomes tedious  and expensive.  The  i976
Quality Criteria for Water recommends a phosphorus criterion of:

     0.10  ug/1  yellow   (elemental)  phosphorus  for marine  and  estuarine
     waters.

     There is no freshwater criterion.

Since water  quality  standards experience  revisions and upgrading from  time to
time, following  procedures  set  forth in the Clean Water  Act,  individual entries in
this  digest may  be superseded.   As these revisions  are accomplished and allowing
for the States to revise  their standards accordingly, this digest will be  updated and

-------
reissued.  Because this publication is not intended for use other than as a general
information resource, to obtain the latest information and for special purposes and
applications, the reader needs to refer  to  the current approved  water quality
standards.  These can be obtained from the State water pollution control agencies
or the EPA or Regional Offices.

Individual State-adopted criteria follow:
