J. H. KLEINFELDER & ASSOCI•ES 6 <br /> Water samples will be delivered under chain-of-custody to a state/EPA <br /> certified laboratory. Chemical analysis will be as shown in Table 1. To <br /> prevent cross-contamination, all sampling equipment will be steam cleaned <br /> prior to use. <br /> 3.5 DISCUSSION <br /> Differences between the Dames and Moore recommended scope for this Phase <br /> II investigation and that proposed by Kleinfelder are: <br /> o For the "penia" solution tank, we propose to analyze for PCP/TCP <br /> rather than total phenols . This tank has not been used for <br /> petroleum hydrocarbons according to Mr. Palmer and therefore TPH <br /> will not be included. <br /> o For the septic tank, we propose to sample the leach field which <br /> has have received the discharge from the tank rather than tank <br /> contents. <br /> o Soil samples from the area having been used for disposal of glue <br /> wash water will be analyzed for total phenols and for <br /> formaldehyde by HPLC using a 2,4-disphenyl hydrazine dervitize* <br /> The formaldehyde rather then the chromotrophic method which is <br /> prone to false positives. <br /> fo Sediment from the drain sump northwest of the 44 A 120 foot <br /> storage building will be analyzed for petroleum hydrocarbons as <br /> 5 <br /> this is the chief contaminant of concern for this sump. <br /> o Water samples will also be analyzed by EPA Methods 601 and 602. <br /> o A set of travel blank water samples is planned. <br /> o Soils adjacent to tanks due for removal and the steam cleaner <br /> drainage ditch soils have previously been sampled and the work <br /> procedures and results will be included in the final report of <br /> findings . <br /> 46-87-282 6 <br /> 1 �l <br />
