I � (KLE/NFELDER ' �&IyM1,Ieryk PigMSolulimc PCE and other VOC contamination generated from former Lincoln Center dry cleaner operations at distances ranging from approximately 50 to 65 feet apart. The western most boring (KB-9) was located approximately 25 feet from the eastern edge of Gettysburg Place. Approximate probe locations are depicted on attached Plate 2. Each of the probes was advanced to a maximum depth of 6 feet bgs. Groundwater was not observed during the probing operations. The push probes were pneumatically advanced using a 4-foot steel core barrel. During advancement of the push probes, soil samples were continuously collected for logging purposes, field screening, and potential chemical analysis. Soil samples were collected by inserting a new 4-foot acetate liner into the core barrel prior to each drive. Soil samples obtained for potential chemical analysis were collected at desired intervals (approximately 3, 4 and 6 feet bgs), by removing the acetate liner from the boring and cutting out the desired 6-inch interval. The soil samples were then sealed with Teflon® sheeting and tight-fitting plastic end caps. En CoreTm soil samples were collected directly from the acetate sleeves for those samples to be subsequently analyzed for VOCs. The soil samples collected were field screened using a photo-ionization detector (PID) as described in Appendix B, Section B-2.3. PID readings were recorded on the boring logs located in Appendix A. PID readings were found to be negative (0 parts per million by volume). No obvious petroleum odor or discoloration was noted from the soil cuttings or samples collected in the nine probes. The soils were logged for lithologic classification based on the Unified Soil Classification System. Approximately one foot of asphalt and aggregate road base was noted during initial probing at the nine probe locations. The soils generally included fat clays (CH) with trace silt and sand from 1 to approximately 3 feet bgs, underlain by a brown to yellowish brown silty sand and sandy silts with clay (ML) to the total explored depth of 6 feet bgs For additional details see baring logs in Appendix A. 4.3 SAMPLE COLLECTION, HANDLING AND CLEANING After collection, the soil samples were labeled, logged on a chain-of-custody form, and immediately stored in an iced cooler pending transportation to the analytical laboratory. 133385.4//ST013R0698 Page 6 of 12 January 7,2014 Copyright 2014 Kleinfelder
