28 April 1995 <br /> AGE-NC-95-0112 <br /> rPage 4of4 <br />' concentrations of dissolved hydrocarbons in monitoring wells. <br /> Concentrations of petroleum hydrocarbons continue to fluctuate greatly in NIW-l. Between <br /> June 1994 and October 1994, TPH-g concentrations in M\x'-1 decreased from 88,000 ppb <br /> to 9,200 ppb. However, between October 1994 and January 1995, TPH.g concentratiolis in <br /> MW-1 increased from 9,200 ppb to 42,000 ppb. This correlates with the rise in groundwater <br />' elevation and a subsequent "washing" of hydrocarbons from the impacted soil. A similar <br /> pattern was also observed in MW-4 where TPH-g increased from 130 ppb in October 1994 <br />' to 370 ppb in January 1995. <br />' 6.2. SOIL AND GROUND NATER REN1L-DIATIO\` <br /> It is our understanding that an access agreement has been obtained frolll the owner of the <br /> A & W site. Therefore, implementation of the FRP should commence as soon as possible. <br /> AGE is currently in t11e process of obtaining the necessary permits and scheduling proposed <br /> work. AGC anticipates installilla all necessary facets for remediation during the second <br /> quarter of 1995. <br /> 7.0. LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily <br /> cticing <br /> ill tills or similar localities. The flndings <br /> exercised by environmental consultants pra <br /> were based upon analytical results provided by an independent laboratory. Evaluations of <br /> the geologic/11yc11.00eo106c conditions at the site for the purpose of this investlgattoll are <br /> oracle from a limited number of available data points (i.e. monitoring wells) and subsul-face <br /> conclitiolls nlay vary -wxay from these data points.
