�LEARWATE� <br /> c. a c> U r <br /> • EnvironmtneRl Srrvices <br /> Project Status and Recommendations <br /> Based on predictable attenuation of post-remediation dissolved-phase contaminant concentrations to <br /> background water quality levels and the fact that all detectable contaminants do not exceed primary <br /> MCLS, Clearwater reiterates the request for regulatory case closure <br /> The project will continue to be monitored on a quarter-year basis until otherwise directed by the <br /> regulating agencies Monitoring will be performed in the same manner as the event presented herein <br /> Clearwater recommends continued analysis of groundwater samples only for TPHg / BTEX by EPA <br /> Methods 8015M/8020 or 8250B, and MTBE by EPA Method 8260B No other Fuel Oxygenates have ever <br /> been detected at the site, except one detection of TBA at 39 pg/L in well MW-2 during May 1998 <br /> However, since that tune, neither TBA, ETBE, DIPE, nor TAME has been detected at the site Therefore, <br /> Clearwater recommends the removal of these compounds from the analytical schedule <br /> ZB107C GWMR 1Q01 5 March 19, 2001 <br />
