FOURTH QUARTER, 2000, SURFACE WATER MONITORING <br />' 41 FIELD METHODOLOGY <br /> On December 13, 2000 a Condor representative was on site to conduct quarterly surface water monitoring <br />' activities I he monitoring activities included the c,ollcction of surface water samples from the drainage ditch and <br /> island drainage channel located east and south of the site, respectively (1~figure 5, Appendix A) Four surface <br /> water samples were collected with a Teflon@ dipping cup and transferred to three 40-milliliter glass vials fitted <br /> with Feflonl-R�-lined caps Surface water samples DDS (drainage ditch south) and DDN (drainage ditch north) <br />' were collected approximately five feet and 100 feet north of Eight Mile Road, respectively Surface water <br /> samples IDCW (island drainage Lhannel west) and IDCE (island drainage channel east) were collected from the <br /> western terminus of the island drainage channel and approximately 100 feet east of the confluence of the <br /> drainage ditch and the island drainage channel, respectively Each sample container was labeled and placed in a <br /> cooler chilled with ice and delivered under chain-of-custody procedures to GcoAnalytical Laboratories, Inc , in <br /> Modesto, California Results of the laboratory analyses are included in Section 4 3 <br />' 4 2 LABORATORY ANALYTICAL METHODOLOGY <br />' The laboratory analytical methods for the surface water samples collected on December 13, 2000, are <br /> summarized in Table 4 <br />' TABLE 4 <br /> Laboratory Analytical Methods <br /> Analytes <br /> B`1"EX TPIf-G Gasoline <br /> Oxygenates/Additives <br /> Analytical Methods 8021B 5030/LUFT 8260B <br /> Detection Limits 0 3 pig/1 (BTE) 0 05 mg/L 1 0 lag/L <br /> 0 6 µg/L (X) 10 0 ltg/L (tert Butanol, <br /> ethanol) <br /> mg/1 milligrams per liter(parts per million) µg/L= micrograms per liter(parts per billion) <br /> B ITX benzine toluene ethyl benzene and total xylenes <br />' rm-G total petroleum hydrocarbons quantified as gasoline <br /> Gasoline oxygenates/Additives=mtthyl tertiary butyl ether(MI BE),ethanol tertiary-butanol <br /> di-isopropyl ether(DlPh) ethyl tertiary-butyl Lther(E TBE)and tertiary amyl methyl ether(TAME) <br /> 4 3 LABORATORY ANALYTICAL RESULTS <br /> BTEX, TPP-G, and the gasoline oxygenates were not detected at or above the laboratory reported detection <br />' limits in any of the surface water samples A summary of the current and historical laboratory analytical results <br /> of the surface water samples is presented to Table 5, on the next page The current laboratory analytical results <br />' of the surface water samples are shown in Figure 5, Appendix A <br />
