Geological Tecluucs inc. Page 7 <br /> Groundwater Monitoring Report <br /> Project No. 1030.2 <br /> October 22, 2004 <br /> a The following factors may have a positive contribution to protection of the deeper <br /> aquifers and retardation contaminant migration at this site: <br /> ' o Gradual groundwater gradient slope <br /> o Dominant upward vertical groundwater gradient <br /> o Fine-grained soils <br /> ' o Characterized by silts and clays <br /> o A thick clay unit at approximately 19 feet bgs <br /> ' Recommendations <br /> + A CAP for soil excavation has been submitted, which has been approved. GTI is <br /> ' preparing a budget and will begin remedial activities ASAP. <br /> • Continue quarterly groundwater monitoring. <br /> ' 4.0 LIMITATIONS <br /> This report was prepared in accordance with the generally accepted standard of care and <br /> practice in effect at the time Services were rendered. It should be recognized that definition <br /> and evaluation of environmental conditions is an inexact science and that the state or practice <br /> of environmental geology/hydrology is changing and evolving and that standards existing at <br /> the present time may change as knowledge increases and the state of the practice continues to <br /> improve. Further, that differing subsurface soil characteristics can be experienced within a <br /> ' small distance and therefore cannot be known in an absolute sense. All conclusions and <br /> recommendations are based on the available data and information. <br /> ' The tasks proposed and completed during this project were reviewed and approved by the <br /> local regulatory agency for compliance with the law..
