TBD Pending sample volume requirements and to account for Pilot clean-up study only. Availability of sample cassettes for Dioxins break through on the cassettes. dioxins analysis is questionable. Apparently the supply is low. SW-846 8290 Air pump operated at 2.5L/min for 8 hours to achieve the Silica NIOSH 7500 COPC wkgroup detection limits NIOSH 7500 (XRD) Areas of known activity (living rooms, family Assumed that It behaves the same as asbestos, samples will be door Air rooms) MMVF NIOSH 7400 combined with the asbestos sampling. EMSL MSD.0300

)TE: All samples (cassettes and wipes) will be preweighed by the laboratory or supplier prior to sample collection. After sample collection and upon receipt of the samples by the laboratory, the loratory will weigh the sample wipe or cassette prior to performing the analysis. This may change depending upon the availability of preweighed materials. May collect samples for total dust.
