Please indicate in the report the detection limit value planning to <br /> be used for TCE and other volatile organic compounds. <br /> 3.) Page 5, section 3.3, third sentence; Please indicate in the final report the <br /> proximity of the adjacent push to the initial push. DTSC is concerned that a <br /> second push completed too close to the first would skew the lithologic <br /> information due to localized deformation in the soil matrix. <br /> 4.) Figure 1; The figure shows the 0.5 parts per billion TCE isopleth in the North <br /> Balloon is off-depot and north of Roth Road. The TCE plume's leading edge <br /> could potentially be outside of DDJC-Sharpe's well monitoring network. <br /> DTSC recommends DDJC-Sharpe place a CPT transect line running east <br /> west to intercept the axis and adequately define the plume's lateral extentc. <br /> If you have any questions or comments regarding this letter, please feel free to conta t <br /> me at (916) 255-3713, or e-mail me at pmacnich(a dtsc.ca.gov. <br /> Sincerely, <br /> /& <br /> Peter MacNicholl, P.E. <br /> Remedial Project Manager <br /> Office of Military.Facilities <br /> cc: See DDJC-Sharp Distribution List. <br />
