Workshop to Examine ''Body Toxic''
Pollutants
SACRAMENTO, Calif.--(BUSINESS
WIRE)--Sept. 6, 2002--The Association of California Water Agencies
(ACWA) is sponsoring a one-day workshop September 19 in Sacramento
to inform its members about the latest emerging water quality issue
-- Xenobiotics.
Xenobiotics,
also known as "body toxics," are products like coffee,
hair spray, cleaning agents, prescription and over-the-counter
drugs, which are used daily in American homes. These products are
designed to provide convenience, make us feel better and help us
heal faster, but they may also constitute the latest water quality
concern.
ACWA's workshop, titled
"Xenobiotics: The Newest Threat to Water Quality?," will
bring together a host of experts including: Jerry Ongerth, East Bay
Municipal Utility District; Dr. David Sedlak, U.C. Berkeley
Department of Civil and Environmental Engineering; Dr. Shane Snyder,
Southern Nevada Water Authority; and Dr. David Spath, California
Department of Health Services (DHS) Drinking Water Program.
While these so-called body toxics are
familiar, little is known about why they are being detected in our
waterways, what the health risks might be, and what can be done to
prevent them from entering drinking water sources. These resilient
contaminants have likely been in the environment since consumer use
began, but are now gaining attention as better technology allows
detection.
The one-day event, to be held at the
Holiday Inn Capitol Plaza in Sacramento, will address the kinds of
contaminants being found, their potential effects on wildlife,
humans and groundwater recharge and how improved technology is
aiding their discovery. Options for drinking water and wastewater
treatment will also be explored along with educational and
collaboration opportunities.
WHO: Association of California
Water Agencies (ACWA)
WHAT: "Xenobiotics: The
Newest Threat to Water Quality?" An educational workshop
WHERE: Holiday Inn Capitol Plaza
300 J Street, Sacramento, CA
WHEN: Thursday, September 19,
2002, 9 a.m. to 4 p.m.
ACWA is a statewide association whose
440 members are responsible for about 90% of the water delivered in
California.

SpiraLift
Screenings Conditioner
Livingston, NJ -- The SpiraLift Model
SC Screening Conditioner is the latest addition to Franklin Miller's
innovative line of shaftless screw screening devices. The SC takes
screenings from a bar screen and washes, dewaters, compacts and
deposits them, ideally conditioned, in a container for disposal. The
SpiraLift SC can be installed behind a new mechanical bar screen or
as a convenient retrofit to an existing installation.
In
operation, the bar screen automatically removes solids from the
liquid channel and deposits them by gravity into the SpiraLift SC
hopper. The SC unit utilizes a rugged Taskmaster grinder to reduce
the solids to a small size. The ground solids are intensively spray
washed to remove contaminants and organics. The washed and ground
screenings are then conveyed from the system by the efficient
shaftless screw unit. The organics are discharged back into the
flow.
The SpiraLift SC is a compact,
free-standing unit that can be easily placed in tight plant
locations. The unit can be fixed mounted or configured for portable
operation to handle the output from multiple sources. The SpiraLift
tank enclosure and hoppers are constructed of durable stainless
steel. A PLC-based control system that monitors and integrates the
entire system operation is supplied.
Other versatile units in the
SpiraLift series include the SL which is designed for headworks
channel installations, and the SR, SR2 and SR3 which are fully
enclosed septage receiving systems for receiving and separating of
septage solids.

Survey Shows Public Willing to Pay
High Quality Water
FOUNTAIN VALLEY, Calif. - A recent
public opinion survey by Orange County Water District (OCWD) shows
that 68 percent of the voters in north and central Orange County
would pay $5-$10 more per month to increase the quality of their
water. Another 75 percent of those surveyed said they would pay
higher rates to increase the reliability of their water. The phone
survey polled a random sample of 500 registered voters from the OCWD
service area in north and central Orange County.
In drought times like Orange County
is currently experiencing, support from the public is important to
water agencies in order to carry out necessary projects and programs
to maintain water resources in Orange County's semi-arid,
desert-like climate. Voters do not believe the current supply of
water is unsafe, but they are supportive of efforts to prevent
safety concerns, such as safeguarding against droughts and pipeline
breaks.
The following findings summarize
results of the survey:
72 percent of those polled said
development of new water sources is necessary, even if it will
be more costly
70 percent say they are satisfied
with the quality of tap water in Orange County and appreciate
having reliable and clean water available when they need it,
although nearly 75 percent either drink bottled water or
filtered water for the taste
74 percent said the quality of
Orange County tap water has stayed the same over the last five
years
79 percent said that Orange County
needs more recycling and reuse.
An overall theme throughout the
survey showed that many of the respondents already incorporate
conservation into their lives and felt they couldn't do much more to
conserve water. But, they are very supportive of conserving water
and reusing water, and nearly all those polled believed more could
be done to reuse and recycle existing water supplies in Orange
County.
Key findings from the survey
revealed:
Voters are not overly concerned
about water supply compared to other issues, like education and
traffic
Safety is more of a concern than
cost and reliability of the water
Only about half of the voters read
their annual water quality reports
Voters do not believe water bills
are too high
Orange County Health Care Agency
is the most trusted source for water issues; OCWD ranked second.
OCWD's goal for the survey was to
learn more about the attitudes of residents in north and central
Orange County regarding their water supply. OCWD will use the
results of this survey to formulate future information and outreach
programs and materials to better serve the public.

NAS Biosolids Report Finds No
Evidence of Health Risk
(Alexandria, Va) On July 2, 2002, the
National Research Council (NRC) of the National Academy of Sciences
(NAS) released its report, Biosolids Applied to Land: Advancing
Standards and Practices. This report represents the culmination of
18 months of work by a diverse committee of distinguished
scientists, academicians and regulators with varying perspectives on
biosolids utilization.
The National Biosolids Partnership
(Partnership) appreciates the work done by NAS in producing its
report, and notes the report's "overarching finding" that
"there is no documented scientific evidence that the Part 503
rule has failed to protect public health" further reinforcing
what many years of operating history at numerous biosolids
facilities have shown. The Partnership also supports the report's
finding that there is a need to update the scientific bases of the
rule and the report's recommendations to:
· Use improved risk-assessment
methods to better establish standards for chemicals and pathogens ·
Conduct a new national survey of chemicals and pathogens in sewage
sludge · Establish a framework for an approach to implement human
health investigations · Increase the resources devoted to EPA's
biosolids program.
The Partnership has been an active
proponent of improvements in the way biosolids are applied and
managed, in particular being the primary developer of an
Environmental Management System (EMS) for Biosolids by publicly
owned treatment works (POTWs). The baseline for the EMS is total
compliance with all biosolids regulations. The EMS also commits the
POTWs that implement it to follow extensive environmental and
best-practice guidelines, seek continuous improvement in the way
they manage their biosolids, seek public input, submit to inspection
and verification by third-party auditors, and make the results of
the audit available to anyone who expresses an interest.
According to Bob Hite, chairman of
the Partnership, "We believe the NAS biosolids report adds to a
collection of studies that show there is no scientific evidence that
biosolids regulations have failed to protect public health, and
reflects a general agreement concerning a need to continue with
scientific research on biosolids." The Partnership urges the US
EPA to continue taking comments from the public and to consider the
report's recommendations in its budgeting process. The Partnership
also urges Congress to provide EPA the funding necessary to conduct
further research, enforce the Part 503 rule, and enhance
communication required to continue recycling biosolids through land
application as a viable option for society."
Formed in 1997, the National
Biosolids Partnership (NBP) is a not-for-profit alliance of the
Association of Metropolitan Sewerage Agencies (AMSA), Water
Environment Federation (WEF), and U.S. Environmental Protection
Agency (EPA). The NBP's goal is to advance environmentally sound and
accepted biosolids management practices.
