SxAsbestos structures,ccecubic centimeters, mm=smillimeter <= lets than, Flow Rate in liters per miuzte ing, Philips 400T Transmission Electron Microscope. Asbestos identification is determined by the morphology, visual Selected Arce Electron Elemmal Aaalysaorng on Energy Dispense e X-ray Anslyzer (EDAX). is calculated by taking the namber of asbestos structures and dividing by the area analyzed. Air concentration is calculated by nnuliiplying the effective filter area (EEA) by the filter concentration and then dividing by the volume of air collected ia cubic centimeters (cc). relates only to air fiber content. When samples are submitted by an cutside agency for analysis, Enviroscience. can only guarantee the ter concentration.

This report can not be ased to claim by NVLAP or any agency of the U.S. Government. the response action area demonstrated a filter concentration of asbestos less than seventy structures per square millimeter. This cespoase complete according to EPA 40 CFR 763, square millimeter is only applicebie to the area analyzed. Test results only reflect conditions at the time samples were taken. 03/28/2821 18:14 H3158232195 ENY TROSCIENCECNSL. TAN PAGE 13 NYC 9/11 Public Portal Document
