TIDBITS OF DATA FROM THE CANAGAGIGUE CREEK REPORT
ppm=parts per million ppt=parts per trillion
New Jerusalem Rd. area had the following results for DDT and metabolites in soil. The Table 8 standard for 2,4 + 4,4 DDD is .05 ppm and the maximum concentration found was 72.7 ppm. The Table 8 standard for 2,4 + 4,4 DDE is also .05 ppm and the maximum concentration found was 3.974 ppm. The Table 8 standard for 2,4 + 4,4 DDT is .078 and the maximum concentration found was 399.3 ppm.
For dioxins and furans found in soil samples in the New Jerusalem Rd. area of the creek the Table 8 standard is 7 ppt and the maximum concentration found was 242 ppt. These maximum exceedances are anywhere from eighty to a few thousand times higher than the MOE Table 8 standards for these toxins found in soils in and around the Canagagigue Creek.
The same geographical area has higher exceedances for dioxins and furans found in the creek sediments (i.e. the bottom of the creek).The Interim Sediment Quality Guideline (ISQG) is .85 ppt and the Probable Effect Level (PEL) is 21 ppt. The maximum concentration found was 1,090 ppt.
Further downstream in the creek at what Lanxess call Reach Three soil samples had 2,4 + 4,4 DDT at a Table 8 standard of .078 ppm had a maximum concentration of 38.52 ppm or approximately 500 times higher than the standard.
At this same location dioxins and furans in sediment samples at a Table 8 standard of .85 ppm had a maximum concentration of 134 ppm which is approximately 150 times higher than the standard.
These figures are just a small sampling of the big picture. The creek is an environmental disaster based upon all the criteria and standards in existence yet through mathematical manipulations and contortions combined with locational sampling biases and just plain weasel wording, self-serving assumptions and so much more we will all eventually be advised that oh we've found two or three hot spots that will take some remediation but then all will be well in the creek. If only it were so.
