The volume of the grout pumped into each well was obtained by <br /> monitoring the level in the drum used as a grout container. _ <br /> The following table gives the actual volume of grout pumped. <br /> Well Grout Pumped Variance from <br /> (gallons) Csg Volume <br /> Mw-1 6 +187% <br /> MW-2 8 ..+250% <br /> MW-3 11 . +340% <br /> The actual grout pumped exceeded the calculated casing volume in all cases, indicating <br /> the grout reached and filled the pores of the filter pack. <br /> Upon completing the well abandonment, the open well boxes or grout cap (in the case of <br /> MW-1) were left for the building construction contractor to finish to the building grade to <br /> meet their own requirements. <br /> 1 <br /> - <br /> 2937 Veneman Avenue, Suite B240 Geo-Phase Environmental Inc.
