<br /> WELL DESTRUCTION ACTIVITIES ? Sart Jo4 1" C00n t' #fwo{K�
<br /> Prior to drilling, well destruction permits w e obtained from SJCHED and an encroachment
<br /> permit was obtained from the City of Banta for offsite wells MW-12, MW-14, MW-16, and OS-2
<br /> through OS-5 to be destroyed. A right of entry was obtained from Union Pacific Railroad for
<br /> offsite well MW-15. Underground Service Alert was contacted for identification of public
<br /> " utilities at or entering the project site. All well destructions were conducted by V &W Drilling,
<br /> Inc. a C-57 licensed drilling company of Stockton, California, in accordance with County and
<br /> State regulations.
<br /> r
<br /> On June 5, 6, 7, and 11, 2013 Apex personnel supervised the destruction of onsite and offsite
<br /> groundwater monitoring wells MW-1 through MW-3, MW-4A, MW-5, MW-6, MW-9 through
<br /> MW-18, monitoring and vapor extraction wells MW-7NEW-4, MW-8NEW-3, vapor extraction
<br /> wells VEW-1, VEW-2, recovery well RW-2, and ozone sparging wells OS-1 through OS-10.
<br /> Monitoring wells MW-1, MW-2, MW-3, MW-4A, MW-5, MW7NEW-4, MW-8NEW-3,
<br /> MW-9, MW-10, MW-12, MW-15, MW-18; ozone sparge wells OS-1, OS-2, OS-3, OS-6, OS-7,
<br /> y OS-8, and OS-10; vapor extraction wells VEW-1 and VEW-2, and recovery well RW-2 were
<br /> over-drilled to depth and filled with a Portland cement slurry to approximately 1 foot below
<br /> ground surface (bgs). Borings were capped with soil, concrete, or a cold asphalt patch to match
<br /> the surrounding surfaces.
<br /> Wells MW-6, MW-11, MW-13, MW-14, MW-16, AND MW-17; and ozone sparge wells OS-4,
<br /> OS-5, and OS-9 were pressure grouted with a Portland cement slurry for ten minutes at 25 psi.
<br /> The top three feet of the wells were drilled out with a 30 inch auger. The well casing was cut off
<br /> six inches above the bottom of the three foot hole and capped with a one foot thick "mushroom
<br /> cap" of cement slurry. The borings were then backfilled with lose soil and capped with soil,
<br /> concrete, or a cold asphalt patch to match the surrounding surfaces.
<br /> REMEDIATION PIPING ABANDONMENT ACTIVITIES
<br /> On June 11, 2013, Apex personnel supervised the abandonment of all horizontal remedial piping
<br /> associated with the former remediation system at the site. The remediation piping was abandoned
<br /> by pouring grout into the piping. Once filled the piping was cut flush to the surface and capped
<br /> with concrete.
