Regarding Tables 3-3 to 3-6 which describe Total DDT and Dioxins/Furans TEQ (toxic equivalency) generally in Creek Reaches 1-4 except for the last Table which oddly only describes Reach 4 (the Lanxess site). These Tables also represent both surface and subsurface Soils and Sediment readings. Sediments of course are in the bottom of the Creek beneath the water and soils refer to creekbank soils above the waterline.
Previously mentioned by myself is the fact that in four pages of Tables; Dioxins/Furans over the four Creek Reaches plus Background (below Reach 1/Grand River) and with 889 samples over many years have an average of 99.87% detection rate. This is beyond incredible, is not remotely normal or ubiquitous and speaks to massive past and ongoing releases of Dioxins and Furans downstream from the Uniroyal/Lanxess property. THIS IS BEYOND SHAMEFUL and no wonder TRAC is so tightly controlled by agenda, membership, meeting times, minutes and limited public access and less.
Total DDT detections are also high although not at the same level of Dioxins/Furans. The lowest detection rate through five locations is 10% and the highest 100% (twice). The average detection rate in the four Reaches plus Background (Grand River) is 57% . Keep in mind this is for DDT only albeit in both Sediments and Soils both surface and subsurface. This also is not "normal" nor ubiquitous.
Regarding concentrations above health criteria the results are startling. Sediment detections are very high for both surface and subsurface DDT and in fact ALL detections from the highest to the lowest EXCEED the health criteria of .00119 ppm. (parts per million) again for Reaches 1-4 and Background (Grand River). Soil detections for DDT on the other hand while ALL maximum concentrations per area (Reach etc.) EXCEED the health criteria of .078 ppm.; minimum concentrations are all below the health criteria.
Dioxins/Furans maximum concentrations in surface Sediments ALL exceed the health criteria of .85 ppt (Parts per trillion) while only two of five areas (4 Reaches & Background Grand River) of the minimum concentrations exceed the health criteria. Subsurface Sediments maximum concentrations for Dioxins/Furans ALL EXCEED the health criteria whereas only one of five of the minimum concentrations for the five areas exceeds the health criteria.
Dioxin'Furan Soil maximum concentrations ALL exceed the heath criteria of 7 ppt. whereas 0 of the five minimum concentrations exceed the health criteria. This is the same for both surface Soils and subsurface Soils.
The title above states that TRAC never do necessary followups to ridiculous presentations. Let me add the following. Maybe they do privately but this is a public process and needs to be clarified to the public each and every time a deceptive, dishonest or blatantly foolish and non factual presentation is made.
