                            INTRODUCTION


     This digest was compiled in order 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 dissolved
solids criteria for interstate waters.   The  water quality standards program is
directed by the Environmental  Protection Agency,  an independent regulatory agency
which has responsibility for approving State-adopted standards for interstate
waters,evaluating adherence to the standards,  and overseeing enforcement of stan-
dards compliance.

     Standards, the first nationwide  strategy  for water quality management, contain
four major elements:  the use  (recreation, drinking water,  fish and wildlife
propagation, industrial, or agricultural) to be made of the interstate water;
criteria to protect those uses;  implementation plans (for needed industrial-
municipal waste treatment improvements, among  others)  and enforcement plans; and
an antidegradation statement to protect existing  high quality waters.

     Minimum water quality criteria,  or numerical specifications of physical,
chemical, temperature, and biological levels,  are stated in the National Technical
Advisory Committee report to the Secretary of  the Interior, Water Quality Criteria,
dated April 1, 1968, and published by the Government Printing Office, Washington,
D.C.  Unavailability of the NTAC report before June 30, 1967--the date set by the
Water Quality Act of 1965 for  formal  adoption  of  State standards--resulted in
significant variations between the state-adopted  and the NTAC minimum criteria.
Some standards were adopted and approved before the NTAC report became available.
Also, the Water Quality Criteria report is subject to updating in light of new
scientific and technical information.

     Although natural waters contain  dissolved solids consisting mainly of
carbonates, biocarbonates, chlorides, sulfates, phosphates, and possibly nitrates
with traces of metallic elements, increases  in these substances above normal are
undesirable and sometimes detrimental.   Concentrations or effects of these sub-
stances can be raised or synergistically altered  by, for example, the addition of
chemical wastes, dissolved salts, acids, alkalis, gas and oil-well brines, or
irrigation drainage.  Adverse  effects may be unpalatable drinking water, fish kills,
crop damage, or eorrosion damage in water systems.

     The Water Quality Criteria report recommends that dissolved solids con-
centrations not exceed 500 mg/1 for drinking water supplies; and for the protection
of freshwater fish, concentrations should not  exceed 50 milliosmoles (the equivalent
of 1500 mg/1 NaCl).

     Since water quality standards experience  revisions and upgrading from time
to time, following procedures  set forth in the Federal Water Pollution Control Act,
individual entries in this digest may be superseded.  As these revisions are
accomplished, this digest will be updated and  reissued.  Because this publication
is not intended for use other than as a general information resource, for the
latest information, and for special purposes and  applications, refer to the existing
approved water quality standards which can be  obtained from the State water pollution
control agencies or EPA Washington, D.C. or regional offices.

     Individual State-adopted criteria follow:
