EPA responding to Dow's outrageous
drops of ink in 55 gallon drum analogy
Would appear EPA did not take lightly Dow's PR spin to down
play the significance of 1.6 million ppt hot spot in the Saginaw River or
the company's attempt to brush aside their dioxin contaminating fish and
then people who eat the fish.

FOR IMMEDIATE RELEASE
Note to correspondents: More information on new dioxin hot spot in the
(Chicago, Ill. - Nov. 14, 2007) Recent published statements by a Dow
Chemical Co. spokesman regarding the company's discovery of another dioxin
hot spot in the Saginaw River may leave the public with mistaken impressions
about the health concerns related to this finding and exposure pathways.
Comparing a highly toxic chemical such as dioxin to ink drops in a drum as
Dow recently did, minimizes the real concern regarding dioxin's toxicity and
the very high level found.
Dow reported a preliminary result of over 1.6 million parts per trillion (ppt)
from a single sediment sample in the Saginaw River. Until now, the highest
level found in the Saginaw River was 32,000 ppt. Under June 2007 EPA orders,
Dow has been removing three dioxin hotspots from the Tittabawasse River
which had concentrations of up to 87,000 ppt.
"The sediment concentration recently reported by Dow is probably the highest
level ever found in the Great Lakes," said Dr. Milton Clark, EPA Region 5's
senior health and science advisor. "While not exactly comparable, the
concentration is more than 1,000 times higher than EPA's action level of
1,000 parts per trillion that triggers cleanup of dioxin-contaminated soils
at residences. It is more than10,000 times higher than the State of
Michigan's residential cleanup criterion of 90 parts per trillion."
"Under most circumstances, EPA is more concerned by high levels of dioxin in
sediments because they contaminate the aquatic food chain. EPA national
dioxin guidance and risk assessment approaches indicate that dioxin levels
found in sediments may need to be lower than those in soils to fully protect
public health," Dr. Clark added.
Fish consumption is one of the primary exposure pathways in the Saginaw
River system. Adverse human health effects associated with exposure to
dioxin include impacts to the reproductive, immune and endocrine systems.
Dioxin is also a potential human carcinogen.
Since 1978, the state of Michigan has issued fish consumption advisories for
the Saginaw River Watershed. A recent University of Michigan study revealed
that people consuming fish from the Saginaw River system have higher than
average levels of dioxins in their blood.
The new Saginaw River sample came from a location a half-mile below the
confluence of the Tittabawassee and Shiawassee Rivers, roughly adjacent to
Wickes Park in Saginaw. EPA, Michigan Department of Environmental Quality
and Dow are working to validate the sample result and determine the best way
to remove the hot spot.

the Michigan Dept. of Community Health at 800-648-6942. For information
