26 October 2000 AGE-NC Project No. 98-0466 Page 3 of 8 Kleinfelder,inAmerican Moulding and Millwork Phase lllAssessment eport, dated 06 May 1992, states that the drainage ditch"east" of the cover plant received effluent fi om steam cleaning and the Saw Filing Room.AGE believes this actually refers to the ditch west of tie plant. During a site visit on 18 May 2000,AGE was informed and shown that there was no ditch east of the building and was informed that water from the steam cleaning area had entered the ditch on the west. Kleinfelder reported the oil and grease were detected in surface soil, but not at feet bsg; soil was being removed from the ditch at the time of the Kleinfelder report. PSI reported that metals and chlorinated hydrocarbons had been detected in soil in the west ditch area. On 26 June 2000 AGE advanced several borings in the area of the west c itch to assess the presence of potential contaminants associated with steam cleaning operations.Labe atory analysis ofcollected soli samples confirmed elevated concentrations of TRPH(characterized a 9 motor oil), formaldehyde and metals including chromium, lead and zinc. Analytical results of s '1 samples are included in Table 1.A ground water sample could not be collected in the western ditch/steam cleaning area due to repeated refusal with the geoprobe. Additional soil samples and a grab ground water sample are needed in the area to complete the assessment of TPH-mo and metals in the area. 2.2. LEACH FIELDS Kleinfelder's 15 June 1987 Work Plan-Phase Illnvestigation for the subject site proposed a boring to test soil for pentachlorophenol/tetrachlorophenol (PCP/TCP), total petroleum hydrocarbons (TPH), formaldehyde, lead, zinc and chromium in the septic tank leach field northeast of the Finger Joint Building. AGE infers that the leach field described is the leach field currently in use northeast of the Maintenance building,which is also northeast of the Finger Joint building(approximately 550 feet away), but much closer to the former(approximately 50 feet away). On 26 June 2000,AGE advanced three soil probe borings to assess contamination in this area. Due to soil conditions encountered at the site,the borings were terminated before reaching groundwater. However, soil samples were collected as deep as 35 feet bsg. Laboratory analysis of soil samples confirmed the presence of low concentrations of TRPH (characterized as motor oil) and formaldehyde in the vicinity of the septic tank; the leach field location was not determined. Analytical results of soil samples are provided in Table 1. A second septic leach field lies west of the Millwork building, approximately 1,400 feet north of the septic leach field described above. This leach field does not appearto be referred to in the Kleinfelder documents. AGE advanced two soil probe borings on 26 June 2000 to assess contamination in this septic leach field area. Laboratory analysis of soil and grab ground water samples confirmed slightly elevated concentrations of TRPH (characterized as motor oil), and formaldehyde. Analytical results of soil and grab groundwater samples arse provided in Tables 1 and 2, respectively. Advonced Cc Environmental,Im.
