Over the past quarter the groundwater elevation has risen <br /> about 3 feet from the prior monitoring event. <br /> i <br /> Over the years, the contaminant concentrations have displayed a gradual <br /> downward trend in all of the wells except MW-8B and MW-9. The past several <br /> events suggest, however, that the contaminant plume has migrated to the east <br /> sufficiently to be detectable in MW-10, although the TPH concentration in this <br /> sampling event is much reduced from that of the prior event. <br /> 3.2 Future Work Schedule <br /> Quarterly groundwater monitoring will continue. Construction of the remedial <br /> system is complete. Continuous operation of the new SVEIAS remedial system <br /> commenced in February. <br /> ■ <br /> r <br /> R � . <br /> 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc.
