Only those analytes measured at detectable <br />concentrations in gtoundwater are summarizedrn the table, The complete laboratory <br />report is provided in Appendix 8 <br />Tn6ro 7 _ /:vnnrrdiunlor Aunlv.ces Results <br /> <br />'~ ~ANAL"Y~T1; ~ <br />' _,:' _ GCL ~ ' <br />r. r.. <br />-' :Standard'":. 2L <br />., ~ <br />'StaniiaYd <br />,MW 1e ~.
