The location of the site is illustrated <br /> in Figure 1 -Location Map. <br /> Nine 2-inch diameter ground water monitoring wells(N4NNI-1 through MV4'-9)and one 2-inch diameter <br /> extraction well (EW-1) are currently located on or near the site. The wells range from approximately <br /> 55 feet to 77 feet in depth. Well locations are illustrated on Figure 2 - Site Plan. <br /> PROCEDURES <br /> In preparation for abandonment, each well cover box or monument cover will be removed. Each well <br /> will be filled with grout; a pressure will be applied to each well for approximately five minutes to <br /> ensure grout penetration into the filter pack. After the filter pack has been penetrated, each well will <br /> be over-drilled to a depth of approximately 3 feet. <br /> Fill material (soil) will be used to backfill the top 3 feet for wells located in grass areas (MW-1, MW- <br /> I SfYi Wesl Mat-ch Lame.
