     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 bacteria
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 standards
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 in-
dustrial-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,
B.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 some bacteria, the pathogens,-are injurious to human life and
welfare, the majority, the saprophytes, when naturally occurring are beneficial.
Certainly, as the foundation of the food chain, bacteria are essential to life.
Bacteria act as anti-pollutant agents, and the dissolution of organic matter is
the prime role of bacteria in  stream self-purification.  Because of this function,
certain types of bacteria are  the workhorse of biological sewage treatment plants.

     Bacteria are grouped into aerobic and anaerobic classes.  Aerobic bacteria
thrive in the presence of 02 (free oxygen); anaerobic bacteria thrive in the
absence of free oxygen.  Pollution can cause a superabundance of the saprophyte
population.  Nutrients such as organic matter (sewage, improperly stabilized wood
pulp) and other oxygen-demanding wastes, toxic or other chemical^ and phosphorus,
among other pollutants, can promote nuisance growths and undesirable conditions
for aquatic life and recreational and aesthetic water uses.  They can consume
the free oxygen and create favorable conditions for the growth of anaerobic bacteria.
Anaerobic bacteria are a major factor in lake "deaths."

     Fecal £oliform bacteria are used as an indicator of the possible presence
of pathogens in water.  The Water Quality Criteria report gives permissible coliform
levels of 10,000/100 ml.(milliliters) and fecal coliform levels of 2,000/100 ml.
Desirable criteria levels are  given as 100/100 ml. for coliform groups and 20/100 ml.
for fecal coliform groups.  It states that these "microbiological limits"are:monthly
arithmetic averages based upon an adequate number of samples.  Total coliform limit
may be relaxed if fecal coliform concentration does not exceed the specified limit."

     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 existinj
approved water quality standards which can be obtained from the State water polluti<
control agencies or EPA Washington, D.C. -or-regional offices.•- =  •    .   .  '•••'

 are representative. In addition, the following "General Statement"
 applies:

 Water oriented recreation,  including water contact sports,
 is  a  desirable use of  the waters of the  state everywhere.  Water
 contact activities in  natural waters are not  opposed by  the state
 health agency where routine sanitary surveys  support such  activities,
 and where, in addition, as  a flexible guide-line to  te used in the
 light of conditions disclosed by the sanitary survey,  the  geometric
 means of the number of fecal coliform bacteria  is less than 200/100

              ml and not more than 10% of the samples during any 30 day
              period exceed 400/100.  The policy is advisory only and in ho
              way limits the responsibilities and authorities of local health
              agencies.

                  It is highly desirable for waters comprising the raw water
              supply to a public surface water treating plant that the total
              coliform bacteria should not exceed 100/100 and the fecal coliform
              bacteria should not exceed 20/100.  Nevertheless, raw water
              supplies to surface water treating plants shall not be deemed
              unsatisfactory where the total coliform organisms do not exceed
              20,000/100 and the fecal coliform organisms do not exceed 2,000/100.
              The evaluation of raw water supplies cannot be reduced to the
              simple counting of bacteria of any kind and the foregoing must be
              used with judgment and discretion and this paragraph is not in-
              tended to limit the responsibilities and authorities of res-
              ponsible local governments or local health agencies.
