                      This report provides a mechanism
                     whereby current water research devel-
                     opments from around the world, as
                     reported at the 13th International Con-
                     ference on Water Pollution Research of
                     the International Association on Water
                     Pollution Research and Control, can be
                     highlighted and brought to the attention
                     of other water pollution researchers. In
                     the report are reviews of the conference
                     presentations and invited discussion,
                     poster sessions,  and  pre- and  post-
                     conference seminars, as well as inter-
                     pretive  analyses of informal  develop-
                     ments associated with the Conference
                     that were judged to be of particular
                     relevance to water quality  control
                     activities in the U.S.A. Also included is
                     a section on research needs.
                      This Project Summary was developed
                     by EPA's Water Engineering Research
                     Laboratory,  Cincinnati,  Ohio, to an-
                     nounce  key  findings of the research
                     project  that  Is fully documented 'In a
                     separate report of the same title (see

                     Introduction
                      The International Association on Water
                     Pollution Research and Control (IAWPRC)
                     has sponsored biennial conferences since
                     the first was held in London in 1962.
                     These conferences provide a forum where
                     international researchers and practition-
                     ers can  meet, present technical papers,
                     discuss these presentations, and debate
                     cutting-edge technical issues concerning
                     water quality. Such conferences are an
                     excellent opportunity for the U.S. Environ-
                     mental Protection Agency (EPA) to learn
of the latest developments in the inter-
national arena and to identify research
needs.
  The 13th International Conference on
Water Pollution Research was held in Rio
de Janeiro, Brazil, on August 17-21,1986.
This report summarizes the formal and
informal developments that evolved dur-
ing this conference  and the pre- and
post-conference seminars. The document
was prepared for the EPA by the United
States of America National Committee
(USANC) for Representation of the United
States to IAWPRC.
  Rather than include complete confer-
ence papers with  formal and informal
floor discussion, many of which are pub-
lished in Water Science & Technology,
the full report includes  summary pre-
sentations as prepared by official U.S.A.
participants in the conference. Specific
emphasis was placed on scientific and
technical developments of special interest
to U.S.A. researchers and practitioners,
as well as research needs identified in or
associated with conference presentations.
Basic themes for this conference included
ground  water pollution,  surface water
quality problems, river basin manage-
ment, wastewater treatment and disposal,
sludge treatment and disposal, marine
disposal of  wastewaters,  and  health
aspects  of  water  microbiology  and
virology.

  Technical areas included in the report
are as follows:
  • Stabilization Ponds  and Natural

  Research Needs Identified
   A total  of  66 research  needs were
  identified  by USANC as a  result of at-
  tendance at the Conference and associ-
  ated seminars — 38 dealt with biological
  treatment systems, 14 with water micro-
  biology and virology,  7 with physico-
  chemical treatment, and 7 with other
  topics.

  sponsorship of the  U.S. Environmental
  Protection Agency.
