One trip blank was <br /> prepared on the day of sampling by filling two 40-milliliter <br /> (ml) VOA vials with distilled water. The blank was carried <br /> unopened during the sampling trip- one equipment blank was <br /> obtained at the end of the procedure used to decontaminate the <br /> drive sampler (see Section 2.2) . At the end of this procedure, <br /> the drive sampler was rinsed with distilled water and the water <br /> transferred to two 40 ml VOA vials. The blanks were handled in <br /> a manner identical to the samples collected in the field. <br /> The trip blank was labeled MW-1 and the equipment blank <br /> MW-2. The laboratory was not informed that the samples were <br /> blanks. <br /> Project No. 1232 -3- <br /> F,'.1'YIH(3.�rtfF_NTA1.tlUpiT LTC. <br />
