Examination of these samples was conducted for lhe presence of identifiable <br /> asbestos fibers using polarized light microscopy (PLM) with dispersion slaining in <br /> a�cordance with U.S, EPA/600/R•93I116 Test Method. <br /> For samplas contai�.,�ig more than one separable layer oi materials, the report will include <br /> findings for each layer (label^d Layer 1 and Layer 2, etc. for each individual layer). The <br /> P�a�tE�L�o,� asbestos concentration in Ihe sample is determined by visual estimation. <br /> u <br /> 7 <br /> < AIH,� � For those sampies with asbestos concentrations between 1 and 10 percent based on visua� <br /> E^"K�"i1Lee° estimation, the EPA recommends a prccedure known as point counting (NESHAPS, 40 <br /> s ine�svui Nrer�+ <br /> �•M�w•o^q CFR Part 61). Point coun(ing is a stalis"cally more accurale means oi quantification for <br /> ����.,. <br /> samples with low concentrations of asbestos. If you would like us to further refine the <br /> concenlration estimates of asbestos in these samples using po�nt counting, please lel me <br /> know. <br /> This report is considered highly confidential and will�ot be released wilhout your approval. <br /> Samp;es are archived for M�o weeks following analysis. Samples that are not�etrieved by <br /> the c�ienl are discarded after Mo weeks. <br /> Thank you for using our laboratory services. Please do not hesitate to ca�l if there is <br /> anything further we can assist you with. <br /> Smcerety, <br /> � <br /> ,i. ��, � <br /> i <br /> Nick Ly, Technical Director <br /> nnuson�roxiaihc NVLAP Lab Code 102063-0 <br /> ::ua a�,acnn «� n <br /> yl LI"i 5 WAi91 W tSh. <br /> W W W.11YII�O�.C�T <br /> ill 1�f.ffl.0100 t.tY�.NVI.I��i�CES S]nr <br /> ,� <oe cae i9)r, Enc.: Sampic Results <br /> �.,�,.,. ,., :_, :-,, <br /> /� <br /> /'� <br />
