Symposium
on Municipal

Disinfection
January 26-28, 1982
Holiday Inn-International Drive
Orlando, Florida
CL 03 UV
-------
Purpose
The Second National Symposium on Municipal
Wastewater Disinfection, a sequel to the first sym-
posium held in Cincinnati in September 1978, is
designed to stimulate vigorous, provocative discussion
in three major research areas: health effects and
epidemiology, alternative disinfection technology
development, and design and operation/maintenance
of implemented technologies.
The purpose of the symposium is to create a forum for
discussion and exchange of information on such
topics as: the need for wastewater disinfection, the
adequacy of EPA's research programs in addressing
the States' requirements to protect the public from
disease transmission via waterways, and the design of
alternative disinfection systems.
Target Audience
The symposium will bring together research scientists;
public health officials; design engineers and con-
sultants; and Federal, State, and local officials to
discuss modern, practical aspects of wastewater
research and practices in the United States. The
speakers, who are internationally recognized public
health and research scientists and design engineers,
will present the most up-to-date technical information
available in their respective fields.
Registration/Symposium Site
Attendance will be limited, so early registration is en-
couraged. There is no registration fee required for
attending the symposium. An optional social fee of $20,
made payable to Enviro Control, Inc., will cover the cost
of all coffee breaks and the January 26 luncheon featur-
ing noted guest speaker Arthur Lane, Ph.D., of the Jet
Propulsion Laboratory. (A refund for the optional social
fee will be given only upon cancellation 30 days prior to
the symposium.) All registered attendees and their
guests are invited to attend the reception, with cash
bar, on Wednesday, January 27. To register, simply fill
out the attached registration form and mail to: Second
National Symposium on Municipal Wastewater Disinfec-
tion, c/o Enviro Control, Inc., P.O. Box 827, Rockville,
MD 20851-0827. For further information, call Sheri
Marshall, symposium coordinator, at 301/468-2500.
The symposium will be held at the Holiday Inn, 6515 In-
ternational Drive, Orlando, Florida; 305/351-3500. A block
of guest rooms is being held until January 4, after
which time rooms may be reserved on a space-available
basis. Special guest rates of $40/single and $45/double
occupancy will be extended through the weekends im-
mediately prior to and following the symposium. To
qualify for these special rates, make your reservations
by phoning the hotel directly and referencing the sym-
posium by name.
