EPA Revises Exemptions for
Wastewater Treatment
 Washington,
DC -- EPA announced that it has finalized revisions to the
wastewater treatment exemptions for hazardous waste
mixtures, an action also known as the "Headworks Rule
Exemptions."
The agency is taking steps to
provide flexible and environmentally sound regulatory
management through the following four
revisions:
(1) the addition of two solvents
(benzene and 2-ethoxyethanol) to a list of solvents whose
mixtures are exempted from the rules under the Resource
Conservation and Recovery Act (RCRA);
(2) the addition of an option to directly measure solvent
chemical levels at the headworks of the wastewater treatment
system to the current requirement;
(3) a clarification in the preamble that scrubber waters
generated from the incineration of spent solvents listed in
the headworks rule would be eligible for the exemption;
(4) the addition of listed hazardous wastes as eligible for
the exemption, as well as the addition of non-manufacturing
facilities to those that qualify for this exemption if
certain conditions are met.
Many of these changes are based
on the public comments that EPA received during the public
comment period. The headworks exemptions have been revised
occasionally as new wastes have been added to the lists of
hazardous wastes.
For more information on the
headworks rule, see:

developing our industrial environmental business in the U.S.
market, but our clients are asking us to serve them more
broadly at the international level. Arcadis provides
numerous growth opportunities for BBL, including the
international platform that allows us to further serve our
clients globally. This opens new perspectives for our
staff."

US Builds Water Treatment Plant
in Iraq
 BAGHDAD,
Iraq -- Most Americans take running water for granted. Not
so for some residents near Iraq's northern city of Kirkuk.
Before January 2005, they had never had running water.
The
Air Force Center for Environmental Excellence didn't start
out on a humanitarian mission when it contracted with
Environmental Chemical Corporation International to renovate
and construct Kirkuk Military Base, also referred to as
"K1."
Officials with Multinational Security Transition Command
Iraq set out to supply 40 company, brigade and battalion
headquarters facilities and 30 barracks for the new Iraqi
army. The base included auditoriums, classrooms, firing
ranges, military police detention center and recruiting
center.
To
garrison the 3,000 soldiers, dining facilities, power
generation, wastewater treatment, and physical fitness
fields were added to the project. To ensure, a safe, ample
water supply, a $1.2 million reverse-osmosis
water-purification unit was written into the contract.
Dibis,
a village on the Zab River, 15 kilometers (10 miles) north
of Kirkuk, once had three water-treatment facilities, only
one of which was functioning in 2004. The others, badly
vandalized after the liberation, were in need of
considerable repair beyond the hope of funding.
One of
these, built in 1978, had once boasted a capacity of 7
million gallons per day. Referred to by local residents as
"Military Water," this facility once supplied water to the
K1 military base. Thorough assessment revealed that Military
Water was not damaged beyond the point of no return and
could indeed be repaired within the original budget allotted
to K1 for its water supply.
It was
not a difficult decision to exchange a $1.2 million water
plant for a $700,000 option that could do so much more. Even
though the cost saving was nearly half a million dollars, it
was only the first drop in the bucket. The newly resurrected
Military Water plant not only supplies water to the 3,000
Iraqi soldiers at K1, but also to the nearby Kirkuk Regional
Air Base, where 10,000 U.S. Air Force and Army personnel
currently are garrisoned.
Both
Kirkuk and the town of Dibis benefit from the enhanced
capacity, but the biggest winners are the roughly 25,000
residents living in 13 nearby villages and settlements who
had never known the luxury of running water. Some of these
communities have only 25 homes; two consist solely of
tent-dwellers; and two areas are home to 5,000 internally
displaced people each.
The
individuals responsible may never have the opportunity to
see their work nor to be acknowledged by those who have
benefited; security concerns in the Kirkuk area mean
visitors and villagers alike are at risk. But 25,000 more
Iraqi people now have access to fresh water.

On-Line Continuous Monitoring of Heavy Metals
 Fareham,
UK -- Fast growing environmental and healthcare
diagnostics company, Lab21, has announced an extended
range of applications for its proven OVA 5000 analysis
system, part of its MTI product range. Importantly, the
ASV (anodic stripping voltametry) technique used in MTI
systems can identify the oxidation state of certain
metals. For environmentally significant metals such as
Arsenic and Chrome, this is particularly valuable. The
OVA 5000 process system now offers improved performance
for Arsenic 5 and 3, and Chrome 6. The systems will also
routinely monitor metals such as Zn, Cd, Pb and Cu.
The OVA 5000 can be
installed in current plant or control rooms, or at
remote sites in a simple enclosure. The system provides
on-line continuous batch monitoring. Throughput is up to
288 samples in 24 hours, with fully flexible programming
allowing samples to be taken at specified times, or when
triggered by an external event. Typical detection limits
are better than 10 micrograms per liter (10ppb) for most
metals; accuracy and reproducibility compare well to AAS
or ICP laboratory analyzers. The OVA 5000 is unaffected
by Na, Ca, Cl or Mg in the sample, metals that are often
present in industrial samples.
A simple user interface
allows set up of normal working parameters and
monitoring of results. Data can be stored on CD,
transmitted via a local area network connection (LAN) or
via a 4 - 20mA interface. Alarm relay interfaces can
also be provided to trigger external events.
The OVA 5000 is designed to
be robust, with minimal running costs and
straightforward servicing. Routine maintenance typically
takes just 30 minutes per week. Intelligent software
monitors the instrument and can be set to alarm or
indicate if any parameter is out of specification. Most
new parts are plug and play, and usually do not require
a service engineer call-out.
Monitoring our environment –
proven MTI instrumentation and software, together with
newly launched reagents and consumables, provide Lab21
customers with complete systems that can be used in the
field, in the laboratory – or for process control.
Value-added contract testing of customers samples at our
laboratories in Cambridge (UK) is also available.
