Equipment Decontamination <br /> Prior to sample collection, Geoprobe soil and ground water sampling equipment and hand auger <br /> ' sampling equipment were thoroughly rinsed with clean water after washing with a solution of <br /> Alconox. Geoprobe rods were thoroughly cleaned prior to soil probe bo ' g advancement. <br /> 2.1.4. Logging <br /> ' During drilling activities,sample duplicates were monitored for the prese rice of organic vapor using <br /> an organic vapor meter equipped with a photo-ionization detector (PID: Thermo Environmental <br /> 580A, 10.0 eV,calibrated to isobutylene) and were visually described on boring logs in accordance <br /> ' with the Unified Soil Classification System (USCS). Boring logs are in luded as Appendix A. <br /> ' 3.0. FINDINGS <br /> Laboratory analysis of soil and ground water samples were utilized to assess the hydrocarbon-, <br /> metals-, and VOC-impact on the two media. <br /> ' 3.1 ANALYTICAL RESULTS OF SOIL SAMPLES <br /> Laboratory analysis of soil samples from the above referenced areas detected elevated concentrations <br /> of TRPH, metals and formaldehyde. Contamination by VOCs and PCP and TCP, appears to be <br /> negligible. <br /> Advanced Geo Environmental,Inc. <br />
