LEUMMItL•NERK MNW. WC. <br />'r <br /> The laboratory analyzing the water samples for BTX&E and TP <br /> H as gasoline was <br /> Superior Analytical , a DOHS-certified laboratory. The laboratory analyzing the <br /> samples for TOS was Kennedy/Jenks/Chilton, a DOHS-certified laboratory, The <br /> laboratory analyzing the samples for total coliform was FGL Environmental . <br /> Included in Appendix E are the laboratory OOHS certificates , as well as, the <br /> chain-of-custody and analytical results. <br /> 4.4 GROUNDWATER SAMPLING RESULTS <br /> As discussed in Section 4.3, groundwater samples were collected from soil boring <br /> SBI using a hydropunch and S84 and SB6 using a bailer. However, because these <br /> samples were obtained from the bottom of soil borings and not from properly <br /> developed monitoring wells, these groundwater samples are not considered <br /> representative of actual groundwater conditions at the site. <br /> Representative groundwater samples were collected on October 1 , 1990 from MW1, <br /> MW2, and MW3. Results from this sampling are included in Appendix E. A summary <br /> of the results is presented in Table 3. <br /> Table 3 <br /> Weber Point <br /> .
