‘Standard Methods’ Water Manual Updated, 22nd Edition
 Washington,
DC -- The most widely respected and globally utilized water
examination manual, Standard
Methods for the Examination of Water and Wastewater,
has been expanded and revised and is now available in its
22nd Edition.
Published jointly by the American Public
Health Association (APHA), the American Water Works
Association (AWWA) and the Water Environment Federation (WEF),Standard
Methods reflects
the latest developments in water analysis. One significant
change in this edition is an emphasis on quality
assurance/quality control (QA/QC) practices. Both EPA and
the Standard Methods Committee feel strongly that QA/QC is
necessary to ensure that each method produces accurate
results. In total, more than 40 percent of the book is new
or updated.
“Along with the American Water Works
Association and the Water Environment Federation, APHA is
proud to put forth the updated 22nd Edition of this widely
used and valued manual,” said Georges C. Benjamin, MD, FACP,
FACEP (E), executive director of the American Public Health
Association. “In an effort to remain current with the latest
science and best practices, the latest edition of theStandard
Methods provides
greater guidance on quality control steps for those in the
field.”
”Standard Methods has for many decades been
the trusted source for water professionals,” said AWWA
Executive Director David LaFrance. “The latest edition
incorporates the best available science to help water
professionals achieve all their water analysis and treatment
objectives.”
“The 22nd Edition provides more than 400
proven analytical methods — many officially approved by
EPA,” said WEF Executive Director Jeff Eger. “This manual
belongs on the shelf of any chemist, radiochemist, or
microbiologist who evaluates water quality.”
Since the first edition in 1905, Standard
Methods has
represented the best current practice of American water
analysts, covering all aspects of water and wastewater
analysis techniques. In 1899, APHA appointed a Standard
Methods of Water Analysis committee that was charged with
extending standard procedures to all methods involved in the
analysis of water. The committee’s report constituted the
first edition of the book.

Aquionics’ New Jaz Clamp Spectrometer
 Erlanger,
KY -- The new Jaz clamp spectrometer from Aquionics enables
customers to conduct on-location testing of their UV
disinfection system’s quartz sleeves. The Jaz accurately
validates the life of quartz sleeves, potentially extending
their usable life, and ensures UV disinfection systems are
operating effectively.
The Jaz spectrometer’s special adapter clamps
onto a UV disinfection system quartz sleeve, utilizing fiber
optics to transmit UV light between 200-400 nm. By measuring
the transmittance of light through the quartz sleeve,
customers can verify the proper construction of new quartz
sleeves and assess the level of fouling and/or solarization
of used sleeves.
The Jaz clamp spectrometer is lightweight and
compact, with 1,500 hours of lamp life powered by a
convenient battery or A/C plug adapter. A USB port allows
data transfer to PC for data storage and analysis.

NSF Int'l Develops Tests to Certify Water Filter Bottles
 Ann
Arbor, MI -- NSF International, an independent global
organization that writes public health standards and
certifies products for food, water and consumer goods, now
tests and certifies the filters used in portable water
filter bottles against NSF American national standards for
drinking water treatment products.
NSF International developed the American
national standards for water filtration products more than
40 years ago. One of these standards, NSF/ANSI Standard 42:
Drinking Water Treatment Units - Aesthetic Effects, is used
to verify a drinking water filter effectively removes
contaminants that cause undesirable odor and taste, such as
chlorine. NSF scientists used the standard to develop an
innovative testing method for water bottles with built-in
filters.
NSF International tested four leading
companies’ filters to NSF/ANSI 42. They include Brita,
CamelBak, Cool Gear, and Move Collective (Bobble filtered
water bottle). Collectively, these brands are the first to
have their water filter bottles certified to NSF/ANSI 42,
which verifies that the products can effectively remove
contaminants that cause undesirable odor and taste,
including chlorine.
“The NSF seal on the CamelBak Groove package
lets customers know this product has been independently
tested and surpasses a prominent national standard for
effectively filtering chlorine and improving taste,” said
Jon Austen, Director of Product Management for CamelBak.
“With CamelBak Groove, great-tasting filtered water is
always within reach.”
“These water bottles filters were subjected
to rigorous testing and evaluation before earning
certification to NSF/ANSI 42 and consumers can be assured
that they can trust the claims they see on the packaging of
an NSF-certified water bottle filter,” said Rick Andrew,
General Manager of NSF’s Drinking Water Treatment Units
Program. “NSF develops new test methods based on our
American national standards to support innovative
technologies in the residential water treatment industry.”
Additional Certifications Available
“Additionally, NSF can certify products to
NSF/ANSI Standard 53: Drinking Water Treatment Units -
Health Effects,” Andrew continued. “Certification to this
standard would verify that a filter can effectively reduce
specific health-related contaminants such as
Cryptosporidium, Giardia, lead, volatile organic chemicals (VOCs),
MTBE (methyl tertiary-butyl ether), that may be present in
public or private drinking water.”
To obtain certification under NSF
International’s Drinking Water Treatment Programs, a company
must undergo extensive product testing and unannounced
audits of their production facilities to certify that water
treatment products meet the design, material and performance
requirements of NSF American national standards. Products
that meet all certification requirements may bear the NSF
Mark and are included on NSF International’s product
listings page.

Extreme Effluent Foaming:
Last Friday, during morning rounds, we found
an extreme amount of crisp white foam beginning in the
secondary weirs and building in the effluent channel and
parshall flume then rising out of a manhole on the plant
grounds and boiling out at the river outfall. Anywhere flow
cacasding took place there was foam, but not in areas were
flow was not aggitated.
Case history:
On Monday and Wed our E.Coli rose from <1.0
to 68 and then 130 MPN 100mls. Wednesday afternoon I made a
Process change that included going from 2 Aeration Basins
down to 1 and 2 secondary clarifiers down to 1 due to low
Influent flows, low F/M and SVI, and loss of MLSS
concentration. Our previous TBOD and TSS numbers bounced
around but were within a normal consistent range leading up
to the day of the event. Our BOD results from the composite
sample will not be available until tomorrow.
Here is a theory; We lost Nitrification, for
which reason I dont know, according to rising Effluent pH,
NH3 (0.05 to 24.5 mg/l) and ALK (101 to 200 mg/l) numbers.
So for corrective actions I turned on the MLSS recycle pump
at 1130, and added an anoxic zone at 1430 to help kick it
back to nitrification. With in 2 hrs the foam had stopped
rising and became non existent at the outfall. The trouble
is that our Aeration Basin DT is 12 hrs and the time it
takes to get from the AB to the outfall is well over 2 hrs.
So here is the quandry; Was it a Toxic load
or a Process microbial problem? We are running surfactant
testing on Industrial Pretreatment samples plus
Nitrate/Nitrite profile, Phosphorus, Grease and Oil analysis
to try to determine if it was a toxic event or a Process
Control change event. Any suggestions and ideas would be
greatly appreciated.
