Dioxin Levels in the Tittabawassee hit 100,000 ppt

Levels as high as 100,000 TEQ of dioxin (page 303) are noted in a recent Geo-Morph study document which summarizes dioxin levels in samples collected in and around the first 6 miles of the river down stream of Dow’s Midland plant.  The report contains the results of what looks to be over 3,000 samples collected from various depths and sites including wetlands, in channel, floodplain, levees, and river bank terraces. Sample results seem to vary all over the place, ranging from <10 to 100,000 ppt TEQ.  Note numerous samples collected at the surface contain levels ranging up to 30,000 ppt TEQ on the river banks (page 125) which is over 300 times the States  RDCC (Residential Direct Contact Criteria) of 90 ppt. Go to the TRW web site to view the data.

Details outlining plans to remove these high levels from the river will be discussed at Thursday's meeting. (bleow) While an obvious point of irritation for DEQ management and Dow Chemical the question remains:  what level would DEQ decide was to high and warranted removal? They are on the record  that the 83,000 ppt is too high. Well what about the  80,000 ppt in Reach K or the 43,000 in Reach M, should they be removed? What about the 23,000 in Reach N? ( Reaches are defined sample areas along the 6 mile stretch of the river tested)


No audience with the Board of Commissioners


In a letter from the County Board of Commissioners, Lone Tree Council has been denied an audience with the full board to discuss the DMDF. On advice of county legal counsel we were notified by the Chair that the meeting would not take place. Lone Tree initiated the request with a letter to Board Chairwoman Cheryl Hadsall. We appreciate her consideration and think it unfortunate that legal counsel feels the need to protect the board from a frank discussion about the site………..


We will prepare information for the board and forward it to them individually.
