Penny,

Bj R02100403 Cover R02100403 R02100403 TEQ Letter.rtf Report.rtf Reportxls 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, Chuck Nace Environmental Toxicologist
