1 - - <br /> To sample each well, a pre-cleaned teflon bailer was attached to new braided nylon line and <br /> lowered into the well, filled, and brought to the surface The water in the bailer was carefully <br />' poured into laboratory prepared glass and plastic bottles which were capped with Teflon-lined <br /> caps Sample bottles were labeled with stick-on labels filled out in indelible ink, with the <br /> following information <br />' Site name <br /> Date collected <br />' Time collected <br /> Sample ID <br /> Sampler's initials <br /> t Analysis required <br /> Any other pertinent information <br />' Quality control/quality assurance procedures consisted of the collection of a blind duplicate and <br /> an equipment decontamination nnsate sample The duplicate was collected concurrently with <br /> sample MW-2 and was given the fictitious well/sample name MW-10. The decontamination <br /> t sample (labeled MW-9) was collected from a bailer which had been cleaned by the normal <br /> decontamination procedure De-ionized water was poured into the decontaminated bailer and <br /> then the water was poured from the bailer into the sample bottles This sample serves as a <br />' check on the decontamination procedures for the bailer, ensuring that it has been effectively <br /> cleaned <br /> Samples were sealed in a resealable plastic bag and placed with ice in an insulated chest for <br /> delivery with a Chain-of-Custody document to the WESTON Analytics' laboratory in Stockton, <br /> California This laboratory is certified by the State of California to perform the required <br />' analyses Samples were submitted for analysis of benzene, toluene, ethylbenzene and xylene <br /> (BTEX, EPA Method 8020), total petroleum hydrocarbons as gasoline (TPH-G, EPA Method <br /> 8015-M), total lead (EPA Method 239 2) and for the presence of fecal coliform (EPA Method <br />' 909C) (Table A-4) A copy of the Chain-of-Custody document is included with the Analytical <br /> Report presented in Appendix B <br />' TABLE A-4 <br /> Sample Analysis Schedule <br />' Sample Identification Number Analyses Performed <br /> MW-1 BTEX, TPH-G, Fecal Coliform, Total Lead <br /> MW-2 BTEX, TPH-G, Fecal Coliform, Total Lead <br /> MW-3 BTEX, TPH-G, Fecal Coliform, Total Lead <br /> iMW-5 BTEX, TPH-G, Fecal Coliform, Total Lead <br /> MW-(, BTEX, TPH-G, Fecal Coliform, Total Lead <br /> MW_9 BTEX <br /> MW-10 BTEX <br /> 1 � r <br />' SrKC1RPr5XAREG3Q7'R WP <br /> A - 3 "" <br />
