 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 1976
 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:
