EPA memo (7/30/04) to the MDEQ indicates the results of the Dow/Entrix Wild Game study
in the Tittabawassee River Flood plain are much more serious than the Dow Press release indicates. The EPA goes
on to state that they may need "to become engaged in the dioxin contamination problem
and to re-enforce existing risks to public health and wildlife". A summary of
the memo was published today in the Midland
Daily News. Conclusions:
The contamination has similar characteristics regarding levels of risk and area affected
as the Kalamazoo
and Fox Rivers, which are currently a focus of
the US EPA remediation plans.
It is clear than a persistent, un-addressed dioxin problem exists.
Unacceptable, elevated cancer risk's to public health to frequent consumers of fish.
Potential health risks to persons consuming game.
Dioxin contamination of game indicate contamination of the terrestrial food chain
Unacceptable, serious aquatic ecological risks to fish, fish eating birds, and mammals.
Strong consideration should be given to removal of dioxin contaminated sediments
and flood plain soil.
There is particular concern regarding distortions
of risk information which are causing inaccurate risk messages to the public.
GES memo (7/16/04) to the MDEQ indicates the results of the Dow/Entrix Wild Game study
in the Tittabawassee River Flood plain confirms findings of MDEQ/GES 2003 T.River Aquatic
Ecological Risk Assesement. Conclusions:
Review of the Entrix (2004) report has shown that the data contained therein support one
of the major conclusions of the Michigan DEQ terrestrial ecological risk assessment (GES,
2004), that is that biota and food chains on the Tittabawassee River downriver of Midland
are contaminated by PCDDs and PCDFs. A reasonable conclusion from this is that predators
and scavengers at the tops of these food chains are likely to be even more exposed to
these contaminants than the deer, squirrels, and turkeys sampled in the Entrix (2004)
However, the Entrix (2004) study was designed to generate data for an evaluation of risk
to human health, rather than to ecological receptors. Because of this, design elements in
the Entrix (2004) study, though perhaps appropriate for a human health risk analysis,
result in an underestimation of the contaminant concentrations to which wildlife would be
exposed and, hence, the magnitude of the risks incurred. These design elements comprise:
The sampling was confined to organisms which, because of their diets, are unlikely to
bioaccumulate PCDDs and PCDFs to the extent that other organisms would.
The carcass handling procedures resulted in a likely underestimation of the magnitudes
of the PCDD/PCDF whole-body burdens to which predators and scavengers may be exposed.
The sample spatial distribution almost certainly results in an underestimation of the
PCDD/PCDF body burdens of turkeys in the lower sections of the floodplain, and, hence, in
the potential exposures to their predators and scavengers.

page report which contains the actual data. We welcome anyone to review the data and
provide corrections to those presented on this site. Dow lawyers should love this as
they will be able to bill Dow for another 1000 hours or so. And you can bet if they
find a mistake, they will not reveal it until we are in trial.
Click here to review the Dow Public
Relations spin summary of the study which contains all the speculation, statistical
manipulation, and other types of misinformation. The conclusions are especially
entertaining. According to Dow, If you intend to eat any wildlife from the
floodplain, the game is safe to eat. We say just make sure you get an
"Average" specimen. When you review the data it will be evident that many
specimens exceed the average by orders of magnitue. How lucky do you feel?
"OK, with a great deal of reading and some perseverance one
need not be a rocket scientist to get to the substance of the Dow Wild game study.
Substance being the operative word! Able to spin their abysmal findings and get their
desired headlines and slant, Dows press release in no way reflects the high levels
of dioxin found in these floodplain animals. Dow apparently diluted and or averaged the
numbers south of Midland taking their "sound science" spin to new levels. The
hard data which appeared later on Dows website confirms that dioxin in the
floodplain soils is available to individual game animals at very high levels in many
cases. Some of these animals are very young and many were found to have numbers that
exceed 100ppt TEQ. The national standard is less than .5 ppt. Headlines and news stories
accomplished what Dow wanted ----to convince the public that these game animals were no
more harmful than supermarket chicken. Nothing could be further from the truth. Its
not rocket science take a look at the data yourself. "
"Dows wild game study was spin, not " sound
science" and in fact is tantamount to a lie. There is no excuse and no ethical
justification for this corporate misdeed. If Dow wants people to trust that they are
committed to "sound science" and " working with the community", they
need to stop twisting, distorting, lying and omitting information. "
"One other major distortion? Dows Wild game Study contrary
to their press releases in November and this month, was not approved by DEQ. Resolution to
this issue will never come to fruition so long as Dows misinformation campaign and
manipulation of the facts go unchallenged by those agencies and officials, state and
local, charged with protecting the health and welfare of the people.
