Morris
Forman Community Odor Survey
Zimpro
Elimination Odor Survey Project
A
monitoring program has been initiated prior to shutdown of the Zimpro
process. The purpose of this monitoring is to verify that odors are
significantly reduced as a result of Zimpro odor elimination. For more
information on the Zimpro process and it's elimination refer to the Alternative
Solids Process (ASP).

monitoring reports, click one of the following:

Tower Startup Data - Part 1
Bioroughing Tower
Startup – Part 2
Bioroughing Tower Startup Odor Survey Project
In
April 1995, Bioroughing Towers were placed into full operation at the Morris
Forman WWTP. (Bioroughing Towers are concrete towers filled with plastic
media which act as high-rate roughing filters for the removal of organic
material from the wastewater.) In December 1995, the media in the
Bioroughing Towers collapsed. During time of operation, odors detected
off-site were sometimes attributed to the Bioroughing Towers. Therefore, as
a part of the Bioroughing Tower reconstruction project, plans were made to
cover the towers and treat the air to remove the odorous compounds. In order
to verify the effectiveness of the odor control technology, this Community
Odor Survey project was initiated to document odor levels in the community
before and after the Biotower scrubbers were started up.
The
Odor Survey project was initiated in April 1999. The Bioroughing Towers
(with odor control) were started up in March 2000. Webster Environmental
Associates, Inc. performed the monitoring and assessment of the
odors on a weekly basis from April 1, 1999 through the end of 2000. There are 11 monitoring
points in the community around the Morris Forman WWTP site (view community
site locations map) and there are 7 monitoring points on the Morris
Forman WWTP property (view WWTP site locations map).
Overviews
of the results have been presented to interested people, including members
of the West County Task Force Committee and the Park DuValle Neighborhood
Association. Results from this survey project show that no new odors were
detected after Bioroughing Towers and scrubbers were started.
