- Here comes the sludge But officials say Lowry Landfill
clean-up plan poses no danger
- The state of Washington this week blocked a company from
selling "fertilizer" containing hazardous wastes derived from
nuclear fuel production, but officials here stand ready to implement a
plan that critics say effectively authorizes the spreading of plutonium-laced
sewage sludge on farm fields in eastern Colorado.
- The plan, which could be launched within the next six
weeks, authorizes the city of Denver to treat contaminated groundwater
from the Lowry Landfill Superfund Site at its York Street municipal sewage
- According to the plan, the Lowry groundwater will be
incorporated into the plant's sewage sludge, which has for years been sold
as a commercial composting and fertilizer product known as "Metrogro."
Additionally, the processed sewage sludge -- which industry groups prefer
to call "biosolids" -- will be routinely applied to about 52,000
acres of taxpayer-owned farm lands near Dear Trail, Colo.
- The practice of using sewage sludge as a "fertilizer"
has long been controversial, since such "products" have been
found to contain polychlorinated biphenyls (PCBs), chlorinated pesticides,
heavy metals and tens of thousands of other toxic substances.
- But critics are particularly alarmed with Denver's plan,
since the permit governing the flow of groundwater from the Lowry Superfund
Site authorizes the municipal sewage treatment plant to accept wastewater
containing specified amounts of plutonium, Americium, strontium and other
- "We believe that we have the only case in the United
States where a sewage treatment authority has approved a permit for the
release of plutonium, depleted uranium and other nuclear wastes ... to
become incorporated into sewage sludge 'fertilizer' for ... unsuspecting
farmers and home gardeners," said Denver resident Adrienne Anderson.
"Our investigation of this case over the last four years concludes
that this is a staggering state and federal cover-up of an illegal ...
nuclear waste dumpsite that federal officials wish to ignore."
- There are, in fact, scores of documents -- and at least
one eyewitness -- that declare that nuclear wastes from Rocky Flats were
illegally dumped at the Lowry Landfill prior to its being shut down in
1980. But federal officials downplay the documents, saying they were either
flawed scientifically or drafted by companies in desperate attempt to force
the U.S. Department of Energy to contribute to the landfill's clean-up
costs, or both.
- Nevertheless, despite what may or may not have been dumped
at Lowry, the sewage sludge-based "fertilizer" produced by the
Denver plant will not pose any public health risks, said plant spokesman
- "We have a program in place to have our biosolids
monitored for radioactivity on a regular, ongoing basis by the United States
Geological Survey," Pearlman said. "The biosolids -- whether
they're in the bag or on the fields -- will meet every standard set for
them by the federal and state government."
- Pearlman said that the radionuclide discharge limits
were written into in the Lowry permit as a precautionary measure, and that
they should certainly not be construed as "evidence" that the
landfill contains higher-than-background amounts of radioactive materials.
And as long as the permit levels are adhered to, Pearlman said, the Superfund
Site groundwater will have virtually no effect on the plant's sewage sludge-based
fertilizer, which he said was "perfectly safe" if used as directed.
- "We did the prudent thing by any stretch of the
imagination," Pearlman said. "The way we meant the limits in
the permit was to say, if there was radioactivity out there, this is all
(Lowry is) allowed to discharge to us."
- Critics aren't convinced. They argue that there is no
safe level of plutonium -- and certainly when it has the potential to be
incorporated into a product sold as fertilizer.
- Moreover, the thousands of documents that the Environmental
Protection Agency refuses to make public on the Lowry case is indicative
of a cover-up, critics say.
- Pearlman denies the charge, but he said he can't talk
about the deals that were cut between the city of Denver and the scores
of companies that the EPA identified as "potentially responsible parties"
for the Lowry clean-up.
- "There's no cover-up, but I cannot discuss the financial
arrangements because I would be in contempt of court to do so," Pearlman
- Pearlman said the EPA-backed plan to pump the Lowry groundwater
to Denver's York Street plant could begin as early as next month. For more
