Thanks for forwarding along the las f the post-cleaning
dioxin samples for 125 Cedar Street. I was waiting for the complete package of post-
cleaning dioxin samples until I took a detailed look at them and I as I started to go
through them this morning I realized that the TEQs were calculated using a value of 0 when
the result was non-detect, instead of using of the detection limit for non-detect in the
calculations.
Could the TEQ results be recalculated using is of the detection limit for non-detects?
Also, could the final reporting units for the TEQs be reported in the units of ng/m2
instead of pg?
Thanks,
