AGE-NC Project No. 99-0559 <br />Page 13 of 13 <br />sample collected in the former UST area, yet low concentration of TPH and BTEX <br />are present south of the former UST area at well MW-6. <br />The dissolved MTBE has migrated west of the former UST area in the shallow water <br />table and migrated northwest under Waterloo Road. The vertical migration of <br />dissolved MTBE has been reduced by the advective forces of significant <br />groundwater hydro stratigraphic flow units, particularly at a depth of 100 feet bsg, <br />yet the dissolved plume of MTBE extends well beyond the site and nearly one-half <br />of a mile west of the site. <br />The general combination of free phase petroleum product and a long duration of <br />contamination in the environment likely has generated a vertical diffusion, which <br />likely equal or exceeds the lateral migration distance of the dissolved MTBE west <br />of the site. <br />Advanced GcoEnvironmental, Inc.
