Soil Boring/Temporary Monitoring Well Installation <br /> Direct Push drilling techniques will be used to advance four soil borings at the site. The <br /> borings will be advanced to approximate depths of 30-feet below grade, two of the four <br /> borings will be completed as a temporary groundwater monitoring well. <br /> The temporary monitoring wells will be constructed of a 10-foot length of bottom <br /> plugged, one-inch slotted (0.01 inch) PVC screen. After the sampling activities are <br /> complete, each borehole location will be tremie grouted and sealed at grade with asphalt <br /> or concrete patch, as appropriate. <br /> Soil Sampling/Analyses <br /> Soil samples will be collected continuously from each boring beginning at grade. Each <br /> soil sample will be screened for the presence of volatile organic vapors using a photo- <br /> ionization detector (PID) calibrated to 100 ppm by volume of isobutylene. The PID <br /> readings, soil lithology, and field observations will be documented in the field by <br /> VERTEX. Based on field observations and the PID screening results, VERTEX <br /> anticipates submitting soil samples from strategic soil boring intervals for laboratory <br /> analysis. <br /> Groundwater Sampling/Analysis <br /> VERTEX will collect a groundwater sample from each of the two soil borings completed <br /> as a temporary groundwater monitoring well using dedicated bailers or a peristaltic pump <br /> as appropriate and will be submitted to a laboratory for analyses. Each sample container <br /> will be placed on ice in a laboratory supplied rigid cooler, and chain of custody forms <br /> will be included with each sample shipment. <br /> Thank you in advance for your help with this project.
