Concentration on the filter is calculated by tking the number of asbestos structures and dividing by ie area anityzed. Air oomoentration is calculated by arultiplying the effective filter area (EFA) by the {iMer comcentration and then dividing dy the volame of air collected in cubic ceationzters (cc). The data pertaining to these calculations can be found on the Ashestes Count Sheet, The air filter concentration relates only to air fiber content. When samples are submitted by an ovtside agency for analysis, Enviroscience. can only guarantee the accuracy of the filter conceatration.

The samples collected in the xesponsc action arce demonstrated a fiiter concentration of ashestas less than seventy structures per square miflincter.
