The problem is that the radioactive waste doesn't just stay in the landfill.
The radioactive material is also in the landfill leachate which is then
often pumped to a sewage treatment plant. And then the radioactive sludge is
land applied.
There is the case of a Big Trees public park in Livermore California that
has radioactive hot spots due to the use of sewage sludge with plutonium as
a soil ammendment.

Here in Ontario, White Rose Nurseries wanted to use Port Hope sewage sludge
to fertilizer their nursery operations. Concerns were raised about the
levels of radioactive waste in Port Hope's sewage sludge. Many tons of Port
Hope radioactive sewage sludge sit in storage at the sewage treatment plant
waiting for the finalization of a plan to impound it in 500 year storage as
low level radioactive waste.
(We need to rethink that 'beneficial use' language, don't we?)

More radioactive waste in Ontario landfills
According to a CBC news report, the Ontario government must do more to
monitor the disposal of radioactive waste because it's turning up more often
in landfills.
The Canadian Nuclear Safety Commission said alerts about radioactive waste
went off 119 times across the country last year, up from 13 in 2005-06.
The majority of those alerts came from southern Ontario landfills.
The report says the bulk of the alerts are from small quantities of
radioactive substances that have a medical origin "which pose little or no
risk."
Ontario environmental commissioner Gord Miller is concerned about the lack
of details in the report.
The province's Environment Ministry said the increase in alarms is simply a
reflection of increased monitoring and doesn't signify a growing problem.

Radioactive alarm bells increasingly ring at Canadian waste sites
Nov 4, 2007
OTTAWA - Alarms are literally ringing at a soaring number of Canadian
landfills as radioactive waste is detected in loads of trash.
Alerts went off 119 times in the last fiscal year, up from 13 in 2005-06 and
just three the year before, Canada's nuclear regulator reports.
More than 75 per cent of the alarms were triggered by small quantities of
short-lived radioactive substances of medical origin "which pose little or
no risk," says the Canadian Nuclear Safety Commission in its annual report.
The document offers no details on the remaining cases.
But records obtained by The Canadian Press show several radioactive devices
have accidentally wound up in landfill sites or in the hands of scrap metal
dealers in the last five years.
The incidents highlight growing concern about the disposal of potentially
harmful nuclear materials, and raise questions about gaps in the patchwork
of systems at landfills across the country that monitor and detect such
waste from hospitals, laboratories and industrial plants.
There's simply no way of knowing how often such materials end up in the
trash by accident or otherwise.
Some municipal landfills have radiation alarms, others do not.
British Columbia, Ontario and New Brunswick, for instance, lack regulations
requiring radiation-detection devices at landfills or transfer stations,
where loads of solid waste are temporarily stored before being trucked to
dumps or recycling depots. Quebec plans to have such requirements fully in
place by January 2009.
The gaps are symptomatic of a hit-or-miss regime: low-level radioactive
garbage that can be legally dumped might set off an alarm, while a genuinely
dangerous device could go undetected.
One southern Ontario landfill owner suggests it's easy to get around the
monitors.
"Supposedly, if you have any radiation stuff, what you've been instructed to
do - and you never heard this from me - is go somewhere else and dump it,"
said the owner, who asked not to be identified.
"Dump it in another dump that doesn't have those detection devices because
they don't want to deal with it."
Medical facilities, research labs and construction firms across Canada use
thousands of licensed radioactive tools to carry out every-day tasks, from
measuring soil density and checking for pipeline cracks to eliminating
static and battling cancer.
In February 2004, a gas chromatograph containing radioactive nickel was
found to be missing from the University of Saskatchewan's neuropsychiatric
research unit. Two years earlier it had been sent to a scrap metal dealer,
who in turn dispatched it to a Saskatoon landfill.
The radioactive source was considered low-risk, in no danger of leaking, and
by that time was covered in layers of debris. Otherwise, university
radiation safety officer Debbie Frattinger says, she would have headed to
the dump and started looking for it herself.
"There were no health consequences so we did not go digging for it,"
Frattinger said.
"But regardless of how big it is, you should not misplace them. No,
definitely."
During an April 2005 inventory check, the McGill University Health Centre in
Montreal discovered a measuring device containing radioactive cesium was
missing, concluding it "likely went to landfill."
A radioactivity monitor sounded at a landfill in Ile des Chenes, Man., in
June 2004. Officials determined the load of trash came from St. Boniface
General Hospital, and a subsequent inventory check revealed a device
containing radioactive barium was missing.
The item was retrieved from the landfill and returned to the hospital.
Once radioactive substances are detected, a waste site operator is supposed
to inform the nuclear safety commission. In the event of a high-level
radiation alarm, an inspector will visit the site to investigate.
The nuclear safety commission says a key reason for last year's increase in
waste alarms, the majority of which originated in southern Ontario, was
greater awareness due to a commission poster and pamphlet campaign.
In addition, an increased number of municipal waste facilities and transfer
stations, especially in the Toronto area, have installed sensitive
monitoring systems that detect radioactive substances inside trucks and
other vehicles.
There has also been an improvement in the quality and detection ability of
the systems.
It's important to take a leadership role, said Wes Muir, spokesman for Waste
Management of Canada, operator of 18 landfills across the country.
"We really monitor what's going in our waste," he said. "We've made that
investment in that material because it's an issue, and we're very
conscientious and rigorous with the way our landfills are operated."
Health physicist Stephane Jean-Francois said landfills are not able to
police everything that comes their way.
Jean-Francois, president of the Canadian Radiation Protection Association,
stressed the importance of regulations intended to control the movement and
disposal of radioactive materials that do pose health risks.
Once a landfill alarm goes off, the horse has left the barn.
"In my personal opinion it's already late," Jean-Francois said. "It's very
late."

Investigations of Plutonium-Contaminated Sewage Sludge:
A Summary DRAFT (6/29/05) In 1987, the Lawrence Livermore National
Laboratory (LLNL) was designated a Superfund site by U.S. EPA due to
groundwater contamination.
As a result, the federal government was required to conduct a public health
assessment (PHA) at LLNL. The PHA includes review of available environmental
data, identification of how community members could be exposed to
contaminants from the site, and whether human health has been impacted.
Important elements of the PHA process are the gathering of community
concerns and community participation in the process. In 1997, the California
Department of Health Services (CDHS) began health assessment activities at
LLNL with the federal health agency (Agency for Toxic Substances and Disease
Registry, or ATSDR). The community requested that CDHS look into potential
ways (routes) that plutonium (Pu) contamination reached Big Trees Park. (Pu
has been found at levels above background that would be expected due to
global fallout).
What is plutonium (Pu)? Plutonium is a man-made, long-lived, radioactive and
hazardous metal. Pu was produced for use in nuclear weapons. There are a
number of types, or isotopes, of plutonium.
Pu 239 is the primary isotope handled at the LLNL.In May 1999, the state and
federal health agencies released a report titled, Plutonium Contamination
in Big Trees Park.
The report evaluated potential routes for Pu 239 contamination found in Big
Trees Park (1). Pu-contaminated sewage sludge from the citys treatment
plant was recognized as one potential route for the Pu 239 found in Big
Trees Park because it was available to the public and/or local agencies for
use as a soil amendment from 1958 through1976. The report recommended the
following: 1) Historic distribution of sewage sludge from the Livermore
Water Reclamation Plant (2) should be investigated; 2) Community concerns
regarding LLNL should be studied/surveyed and; 3) A review of health studies
should be conducted relative to LLNL (4). In November 2002, as follow-up to
these recommendations, CDHS released a report titled, Proposed Process to
Address the Historic Distribution of Sewage Sludge Containing Plutonium
Released from the Lawrence Livermore National Laboratory (2).
The report was written in collaboration with the Alameda County
Environmental Health Services, City of Livermore, Western Sates Legal
Foundation, Tri-Valley CAREs, and San Francisco Bay Area Physicians for
Social Responsibility. What is sewage sludge? Sludge is the end
product(solids) of the sewage treatmentprocess. Sludge from the Livermore
Water Reclamation Plant has not been given to the public since 1975. The
main findings of the report are as follows: (Continues on page 2) 1) Sewage
sludge was available to the public and/or local agencies from 1958-1975; 1
--------------------------------------------------------------------------------
Page 2
2) There were unintentional releases of Pu 239 from LLNL to the sewage
treatment facility for the entire period sludge was available to the public;
3) There is a lack of data available to adequately evaluate the potential
health hazard from exposure to the contaminated sludge to the public. As a
result, the exact amount of sludge and concentration of the radioactivity in
the sludge available to the public and agencies is uncertain; 4) Locations
where sludge was placed are unknown and; 5) Residents were unaware that the
sludge could have contained Pu 239.
Based on these findings, the report proposed a process that includes public
participation, environmental sampling, interpretation of potential health
risks, and community outreach and education. The responsible party (LLNL,
run by the U.S. Department of Energy) was identified as the most appropriate
funder of the suggested process. As of 2005, the process recommended in the
Department of Health Services November 2002 report had not been funded.
In August 2003, ATSDR released a public health assessment titled, Plutonium
239 in Sewage Sludge as a Soil Amendment in the Livermore Community (5).
ATSDR uses available data to estimate potential exposure to the community.
ATSDR concludes the estimated radiological doses are below levels of health
concern, thus public awareness/outreach and additional sampling in the
community where sludge may be present would not be necessary.Given the data
gaps and associated uncertainties, CDHS, Alameda County Department of Health
Services, City of Livermore, Western Sates Legal Foundation, Tri-Valley
CAREs, and San Francisco Bay Area Physicians for Social Responsibility
believe the community based process outlined in the November 2002 CDHS
report should be implemented.
