June 2008. ISBN: 0-88864-484-1. 344 pp. Paperback. $34.95<BR>The greatest threat
to water quality worldwide is nutrient pollution. Cultural eutrophication by
nutrients in sewage, fertilizers, and detergents is feeding massive algal
blooms, choking out aquatic life and outpacing heavy metals, oil spills, and
other toxins in the devastation wrought upon the world’s fresh waters. Renowned
water scientists, David W. Schindler and John R. Vallentyne, share their
combined 80 years of experience with the eutrophication problem to explain its
history and science, and offer real-world solutions for mitigating this
catastrophe in the making. For those who have lost sight of Vallentyne’s 1974
first edition, Schindler’s fully revised and expanded edition is an unambiguous
road map for change.<BR><BR><STRONG><SPAN style="COLOR: green"><FONT
size=4>Early Warning and Management of Surface Water Taste-and-Odor
Events.</FONT></SPAN></STRONG> William D. Taylor. 2006. ISBN: 1583214259. 268
pp. Softbound. $355.20<BR>The primary objectives of a taste-and-odor early
warning program are to detect and manage taste-and-odor events before consumer
complaints begin. This is easier said than done; sensitive individuals can
detect geosmin and MIB in drinking water -- the algae-related compounds that
cause common "earthy/musty" complaints -- at almost unbelievably low levels of
< 5 parts per trillion (ng/L). That leaves a very narrow window of
opportunity for the water utility to detect a taste-and-odor event and implement
a management strategy before complaints begin. Seemingly, a majority of
utilities use customer complaints as their early warning system, by which time
the algae bloom causing the taste-and-odor event is already out of control.
Fortunately, numerous monitoring and management strategies exist that allow a
utility to head off taste-and-odor problems before they can cause complaints.
This report focuses on these strategies, offering a set of practical guidelines
and tools that any utility can use for reducing or eliminating taste-and-odor
events.<BR>The report describes and illustrates the MIB- and geosmin-producing
blue-green algae species that create taste-and-odor events. It reviews the
state-of-the-art of sensory and analytical methods for detecting and measuring
MIB and geosmin (comparing the strengths and weaknesses of each method).
Importantly, the report provides a new simplified method of Flavor Profile
Analysis that is less costly and easier to perform than the standard method.
Additionally, the report describes two promising new sensory methods that are
easy to perform, require minimal training, and have low operational costs.
Design guidelines for new facilities are described that can help utilities avoid
taste and odor problems. The report also reviews several readily available lake
simulation models for their value in taste-and-odor management. An included
CD-ROM provides a simplified flavor profile method, lake and reservoir
mathematical model evaluation, key elements important for early warning and
management of taste-and-odor events, detailed information about earthy/musty
tastes and odors, and a sample customer door hangar for taste-and-odor
notification.<BR><BR><STRONG><SPAN style="COLOR: green"><FONT size=4>Addressing
Concerns About Tastes and Odors and Cyanotoxins in Tap
Water.</FONT></SPAN></STRONG> Randy Gottler. 2007. ISBN: 1583215220. 132 pp.
Softbound. $315.20<BR>Algae-related taste-and-odor problems are common among
municipalities that use surface water. Although algae-related tastes and odors
are harmless, they create among consumers the perception of unsafe water and
result in consumer complaints or lead consumers to alternate drinking water
sources (bottled water, point-of-use devices). Early detection of an emerging
algae-related taste-and-odor episode is critical for reducing or eliminating
customer complaints. This research project developed a monitoring and response
program to rapidly assess emerging taste-and-odor problems in the distribution
system.<BR>Specifically, the objectives are as follows:<BR>*Quantify
non-MIB/geosmin compounds from waters and cultures<BR>*Streamline flavor profile
analysis and cyanotoxin methods for routine laboratory
monitoring<BR>*Investigate biological production of taste-and-odor compounds in
the distribution system<BR>*Develop and demonstrate a responsive taste-and-odor
monitoring program<BR>*Provide recommendations for utilities<BR><BR>Scott
