<br /> The above sample scheme will continue for all expected 46 sample points.
<br /> Brine Release Site
<br /> A single sample point will be selected from the pump room of Building 1 of the Stockton
<br /> Cold Storage site. A 6-inch diameter concrete core cutter will be used to cut a hole through
<br /> the concrete floor of the room. Hand auger soil boring tools will then be used to collect a 0
<br /> to 6 inch sample and a 1 to 1.5 foot sample of soil from beneath the floor. The sample pairs
<br /> will be used to gather information regarding the vertical distribution of any contaminants that
<br /> may be identified. The following table provides the expected sample identifiers:
<br /> Sample ID Sample Location Sample Analytes
<br /> Brine 0.5-1.0 Pump Room Brine Release.5 to 1 foot Total Chrome&Hexavalant Chromium
<br /> Brine 1.0-1.5 Pump Room Brine Release 1 to 1.5 feet Total Chrome&Hexavalant Chromium
<br /> Semi-Volatile Organics of Uncertain Origin
<br /> A group of authoritatively selected samples will be collected from several points in the
<br /> vicinity of the building at 1404 W. Weber. The 6 sample points will be on either side of
<br /> large roll-up access doors on other side of the building, and from points on south side of the
<br /> building where a Geoprobe boring previously produced a soil sample with trace
<br /> concentrations of semi-volatile organic compounds.
<br /> The samples will be collected from a depth of 0 to 1 feet and slightly deeper sample will be
<br /> from 1 to 2 feet below the surface. The sample pairs will be used to gather information
<br /> regarding the vertical distribution of any contaminants that may be identified. The following
<br /> table provides the expected sample identifiers:
