Ethylbenzene and Xylene (BTEX) and fuel oxygenates including Methyl-tert-butyl-ether <br /> (MTBE) The analytical reports are attached, and the results are listed below in Table 2 <br /> Table 2 Groundwater Chemical Data <br /> Well No Date TPHG B T E X Fuel Ox <br /> ------------------------------ug/I------------------------------- <br /> MW-1 8/25/97 ND ND ND ND ND ND <br /> MW-2 8/25/97 ND ND ND ND ND ND <br /> MW-3 8125/97 ND ND ND ND ND ND <br /> Blank 8/25/97 ND ND ND ND ND ND <br /> ND - None detected NA - Not Analyzed ug/I - micrograms per liter <br /> Fuel Ox - Fuel Oxygenates <br /> Discussion <br /> Groundwater flow direction appears consistent with historically observed trends Contaminants <br /> were not observed in any well If the none detected trend continues for two more quarters, then <br /> a proposal to close the site will be made to PHS-EHD <br /> Monitoring Schedule <br /> The quarterly monitoring for this site is scheduled to continue at quarterly intervals <br /> Haley Wells Project No 4111 Page 2 _ <br />
