L,C,,- VATC . <br /> A S- S O C I A T E S I N C . <br /> LMW2 and MW3 contained no detectable concentrations of oxygenate fuel additives. Anal ical <br /> Yg Yt <br /> results of groundwater samples are summarized in'Table 3. <br /> 5.0 DISCUSSION <br /> t <br /> Based on the analytical results.and field observations, soil and groundwater beneath the location <br /> of the former UST are i' acted b TPH <br /> p y g and BTEX.. Monrtoring wells MW2 and MW3 were <br /> installed downgradient of well MWl and the former UST location and soil'and groundwater <br /> samples collected from wells MW2 and MW3 contained nd significant concentrations of TPHg <br /> or BTEX. - None of thesoil,orgroundwater samples 'collected from wells MW2 and MW3 <br /> contained oxygenate. fuel_ additives.. Based on this information, "the impacted soil rand <br /> groundwater appears to be limited to the immediate.vicinity of the former UST. In the judgment <br /> of.ATC, additional subsurface",investigation- activities are not .necessary. ATC recommends <br /> conducting three additional quarters.of groundwater monitoring to confirm the groundwater <br /> gradient direction and magnitude and the stability of the petroleum hydrocarbons in well MWl'. <br /> At that time, if conditions warrant,ATC recommends preparing-a request.for site closure report. <br /> - <br /> �t <br /> 1 <br /> wA16393\reports\sumLdoc 5 - <br />
