' Union Ice Company <br /> 425 North Union Street, Stockton, California <br /> Quarterly Groundwater Report(December, 1993) <br /> 1 <br /> Narrative <br /> ' On December 30, 1993, WHF, Inc , in conjunction with F KM, Inc, conducted field measurements, well pumping <br /> and groundwater sampling on four groundwater monitoring wells located at this site(Figure 2) <br /> Groundwater elevations were taken prior to pumping (Table 2), and at least three well volumes were evacuated <br /> from each well using a steam-cleaned, stainless steel bladdem3pe pump, during which time samples were collected <br /> to measure the field pH, electrical conductivity and temperature (Table 3) The samples were collected, labeled <br /> and chilled in an ice chest with Blue Ice® after stability was achieved and a minimum of 3 well volumes were <br /> ' removed The samples were then logged on a Chain of Custody form and transported to Geo Monitor, Inc , a State <br /> certified laboratory located in Hesperia, California The analysis requested for the water samples were EPA <br /> method 602 for BTX&E compounds and EPA method GCFID 3550/8015 for Diesel The analytical results are <br /> ' listed in Table 1 of this report <br /> Groundwater elevations(Table 2)were used from these four monitoring wells to construct a groundwater gradient <br /> map (Figure 2) The gradient has not changed significantly (N69°E at 0 0021 ft/ft) since the October 1993 <br /> sampling event(N600E at 0 0025 fl/ft) Since the last quarter, the water table has dropped 2 0 feet across the site <br /> MW-3&4 analyzed Non-Detect for all tested compounds MW-1 had 0 5 ugfL Toluene and 0 7 pg/L Xylenes <br /> MW-2 had 1 9,ug/L Toluene,0 7 pg/L Xylenes and 0 10 mg/l Diesel Last quarter all wells were Non-Detect <br /> The above represents our best professional opinion as to environmental conditions at this site These opinions were <br /> derived using data at hand, and standards of care common to the environmental consulting community in Northern <br /> ' California Additional work or sampling at this site may generate data that could lead to a change of opinion <br /> regarding site conditions or appropriate site remediation procedures, or both <br /> Prepared by <br /> ��t•"�' 4613 �9 <br /> ' AIPG <br /> ' uis Smith, CPG <br /> Certified Professio logist#4613 t p <br /> Qp,4�EC: <br /> NOQ <br /> CD � 223391x0o <br /> eLano,P E #42339 <br /> EXP 9349'7 ZZD <br /> " <br /> California Registered Civil Engineer cf'J, CML <br /> Or <br /> CA1-���Q� <br />
