0 Lily Street - Limited Phase II Environmental Site Assessment ReportBLACKLEDGE GROUP August 2, 2021 via email c/o: bdurden(a�llw-law.com Mr. Shane Corbin City Manager City of Atlantic Beach 800 Seminole Road Atlantic Beach, Florida 32233 RE: Limited Phase II Environmental Site Assessment Report 0 Lily Street 2.1 Acres Unimproved Land Atlantic Beach, Duval County, Florida 32233 RE# 170977-0000 Dear Mr. Corbin: The Blackledge Group, Inc. (TBG) is pleased to present the results of this Limited Phase II Environmental Site Assessment (ESA) performed on July 13, 2021. The subject site is comprised of approximately 2.12 acres of unimproved property located east of the Intracoastal Waterway. Based the recomtnendations of the Phase I ESA report prepared by TBG, dated June 23, 2021, further assessment was recommended to investigate the use of the subject site as a historical dump site. The scope of work included excavating exploratory trenches and collecting a groundwater sample for laboratory analysis to determine if solid waste was present on the subject site and to evaluate groundwater quality in the area of an on-site pit observed during the Phase I ESA. The background of the site, a description of the scope of services performed as part of this Limited Phase 11 ESA, and the results of the investigation are provided herein. 1.0 BACKGROUND A Phase 1 ESA was performed by TBG, in June of 2021. According to the Phase I ESA the subject site was comprised of a single parcel of land located at 0 Lily Street, Atlantic Beach, Duval County, Florida; and identified by the Duval County Property Appraiser as RE # 170977-0000. The subject site was undeveloped and wooded waterfront property and was heavily vegetated in the central and northern portions of the property. An 8 -to 10 -foot -high soil mound and berm was observed along the western edge of the central and northern portions of the site. A pit filled with standing water was observed in the central portion of the site. A Street Site Location Map and Topographic Site Location Map are included as Figure 1 and Figure 2, respectively. During Phase I ESA field activities and historical records reviews, a recognized environmental condition (REC) was identified. Evidence of the presence of solid waste, including tires and metal debris, was observed in the central area of the site in the vicinity of the pit. The subject site and an adjacent property to the east appeared to have been used as a dump site during the late 1960s and early 1970s. Interviews conducted with people knowledgeable about the past history of the subject site indicated that the site was used for dumping of unknown materials in the late 1960s and early 1970s. It was also reported that during heavy storm and high-water events plastic materials, tires, etc. had been observed floating in the pit. Based on a review of aerial photographs from 1960 to 1970 the northern section of the subject site had been cleared 1450 Flaglcr Avenue Unit #32. • Jacksonville, Florida 32207 • 800-241-6831 Mr. Shane Corbin August 2, 2021 Page 2 and surficial soil had been disturbed. Additionally, evidence of historical excavation and filling activities were observed during the site inspection and was observed on the aerial photographs reviewed. As requested by the Client, TBG performed this limited Phase II ESA, which included the collection of a groundwater sample to evaluate groundwater quality in the area of the pit, and the excavation of exploratory trenches to investigate the presence of buried solid waste in the central and northern areas of the site. 2.0 SCOPE OF SERVICES TBG proposed the following scope of work to evaluate the environmental concerns identified in the referenced Phase I ESA: excavate up to six (6) exploratory trenches approximately 10 foot long by 3 foot wide to a depth just below land surface (bls), estimated to be at 2-3 feet, in the central and northern portions of the site; install one temporary wellpoint in the area of the pit; collect a groundwater sample from the wellpoint for laboratory analysis of the parameters listed EPA Method 8260 Priority Pollutant Volatile Organics Aromatics and Halocarbons, EPA Method 8270 Priority Pollutant Semi -Volatiles, EPA Method 8081 Organochlorine and Organophosphorus Pesticides, EPA Method 8082 PCBs, and 8 RCRA metals; and prepared a letter report summarizing the results of the investigation. 3.0 METHODS OF INVESTIGATION On July 13, 2021, TBG conducted limited Phase II ESA field activities in accordance with the scope of work outlined above and provided to the Client prior to initiating the project. A description and summary of the investigations is presented in the following section: 3.1 Exploratory Trench Excavations TBG mobilized a mini excavator to the site and excavated fifteen (15) exploratory trenches approximately 5 to 10 foot long by 3 foot wide and to a depth of approximately 4 to 6 feet bls, and 2 to 3 feet into the groundwater table which on the average was 2 to 3 feet bls. Exploratory trench excavations were conducted in the central and northern portions of the site in areas that were accessible to the excavator. Excavated soils and solid waste were returned to each excavation trench. The materials encountered were recorded at each excavation trench. Excavation locations are depicted in Figures 3 and 4. A summary of exploratory trench excavation observations is included in Table 1. 3.2 Temporary Wellpoint Installation and Development On July 13, 20201, TBG installed one temporary shallow wellpoint (TMW-1) to evaluate groundwater quality in central area of the site. TMW-1 was installed due east of the middle of the eastern edge of the pit located in the center of the subject site. The temporary well point was installed by hand using a stainless-steel hand auger. The wellpoint was installed to a depth of 6 feet bls, and approximately 4 feet below the groundwater table. TBG was unable to advance the boring further due to the borehole collapsing. The temporary well was constructed using 5 feet of 2 -inch diameter, 0.010 -inch slotted polyvinyl chloride (PVC) well screen threaded to a sufficient length of two-inch PVC casing to complete the well above grade. A 20/30 graded sand pack was installed around the well screen. Mr. Shane Corbin August 2, 2021 Page 3 The wellpoint was developed after installation to ensure hydraulic communication with the aquifer. Dedicated high-density polyethylene tubing was inserted into the top of the well casing and positioned in the area of the well screen in order to develop the well and obtain a groundwater sample. Wellpoint development was accomplished using an adjustable -flow peristaltic pump. Upon completion of the field activities, the wellpoint was removed, the borehole backfilled to land surface, and the surface restored to its existing condition. The location of the wellpoint is depicted on Figure 4, and GPS location coordinates are included in Table 1. 3.3 Groundwater Sample Collection and Laboratory Analyses TBG collected a groundwater sample from TMW-1 using a peristaltic pump with disposable high-density polyethylene tubing. Samples were collected after approximately one hour of well development and as most fine sediments were removed, and the groundwater showed a minimal amount of turbidity. The groundwater sample was collected in laboratory -supplied containers, placed on ice in a shipping cooler, and transported to Advance Environmental Laboratories (AEL) for analysis. The groundwater sample was submitted for laboratory analyses of the parameters listed EPA Method 8260 Priority Pollutant Volatile Organics Aromatics and Halocarbons, EPA Method 8270 Priority Pollutant Semi -Volatiles, EPA Method 8081 Organochlorine and Organophosphorus Pesticides, EPA Method 8082 PCBs, and 8 RCRA metals. Groundwater laboratory results are discussed in Section 4.2 and the laboratory analytical report is included in Appendix B. 4.0 RESULTS OF INVESTIGATION 4.1 Exploratory Trench Excavation Results Results of the exploratory trench excavations found various types of household solid waste, trash, and debris within the pit located in the center of the site; and household solid waste and construction debris in three trenches excavated across the northern area of the site. Solid waste was encountered to a depth of approximately eight feet bls in the pit; and from four to five feet bls in the northern area. The overall depth of solid waste was not determined. A summary of the excavation observations, trench locations, excavation depths, and GPS coordinates for the (15) fifteen exploratory trenches are provided in Table 1. Pictures of the excavation trenches and their contents are included in the Appendix A. Based on the results of the excavations, it appears that the pit was used for the disposal of various types of household garbage, trash and debris. No evidence of the presence of hazardous waste or hazardous materials was observed. The solid waste encountered in the center of the site was contained within the boundaries of the pit and immediate area (EX -4, EX -5, EX -7, EX -8 and EX -1 1). The three exploratory trenches located south of the pit (EX -1, EX -2 and EX -3) did not contain solid waste. Solid waste was not observed in exploratory trenches located to the east and north of the pit (EX -6, EX -9 and EX -10). Based on the historical aerial photographs reviewed and the presence of solid waste in three exploratory trenches excavated in the northern section of the site (EX -13, EX -14 and EX -15) it appears that northern portion of the site was used as a dump and primary disposal area. The solid waste encountered consisted of household garbage to include plastic, bottles, and trash, as well as wood, metal and concrete debris. Excavation trench EX -14, located in a depression in the vicinity of northwest corner of the site, appeared to be the most impacted area. Solid waste was encountered from the surface to the termination of the excavation four to five feet bls. The groundwater and soil in this area was stained black, and an odor indicative of decaying material detected. Mr. Shane Corbin August 2, 2021 Page 4 4.2 Groundwater Laboratory Analyses The results of the groundwater analyses for TMW-1 showed no analytes above either their laboratory Method Detection Limit (MDLs) or respective Groundwater Cleanup Target Level (GCTLs) for EPA Method 8260 Priority Pollutant Volatile Organics Aromatics and Halocarbons, EPA Method 8270 Priority Pollutant Semi -Volatiles, EPA Method 8081 Organochlorine and Organophosphorus Pesticides, and EPA Method 8082 PCB. Four of the eight RCRA metals (Barium 0.12 mg/1, Chromium 0.010 mg/1, Lead 0.0059 mg/1 and Mercury 0.00012 mg/1) exceeded their laboratory MDL but were below their respective GCTL. The laboratory analytical report and the associated chain of custody are included in Appendix B. 5.0 LIMITATIONS TBG has prepared this Limited Phase II ESA for The City of Atlantic Beach, hereafter referred to as the Client. No Phase II ESA can eliminate all uncertainty. Furthermore, any sample, either surface or subsurface, taken for chemical analysis may or may not be representative of a larger population. Chemical testing methods have inherent uncertainties and limitations. Professional judgment and interpretation are inherent in the process, and uncertainty is inevitable. Additional assessment may be able to reduce the uncertainty. Even when soil and groundwater sampling is executed with an appropriate site-specific standard of care, certain conditions present especially difficult detection problems. Such conditions may include, but are not limited to, complex geological settings, the fate and transport characteristics of certain hazardous substances and petroleum products, the distribution of existing contamination, physical limitations imposed by site conditions, location of utilities and other man-made objects, and the limitations of assessment technologies. Measurements and sampling data only represent the site conditions at the time of the data collection. While TBG has used reasonable care to avoid reliance upon data and information that is inaccurate, TBG is not able to verify the accuracy or completeness of all data and information available during the investigation. Some of the conclusions in this report would be different if the information upon which they are based is determined to be false, inaccurate or incomplete. TBG makes no legal representations whatsoever concerning any matter including, but not limited to, ownership of any property or the interpretation of any law. TBG further disclaims any obligations to update the report for events taking place after the time during which the assessment was conducted. This report is not a comprehensive site characterization and should not be construed as such. The opinions presented in this report are based upon the findings derived from limited soil excavation and groundwater sampling. The scope of work performed herein was limited to groundwater sample collection and laboratory analysis of one sample. TBG has endeavored to meet what it believes is the applicable standard of care, and, in doing so, is obliged to advise the Clients of the limitations. TBG believes that providing information about limitations is essential to help the Clients identify and thereby manage their risks. Through additional testing, these risks can be mitigated - but they cannot be eliminated. TBG will, upon request, advise the Clients of the additional research opportunities available, their impact, and their cost. As noted above, the limited Phase II ESA conducted at the referenced site, and this report, was prepared for the use solely by the Clients. This report shall not be relied upon by or transferred to any other party without the express written authorization of TBG. Mr. Shane Corbin August 2, 2021 Page 5 6.0 CONCLUSIONS AND RECOMMENDATIONS The results of limited groundwater analyses showed no tested analytes above their respective GCTLs in the sample collected from TMW-1. Review of historical aerial photographs, performed as part of the Phase I ESA, indicated that the subject site had been cleared and surficial soils disturbed in the 1960 to 1970 photos. In the 1970 photo, the surface of the northern section of the site appeared to be graded and heavily disturbed. Based on the type, quantity and depth of solid waste encountered in the exploratory trenches, it appears that this section of the site was utilized as solid waste dump site. It also appears that the pit located in the central portion of the site was used for the disposal of solid waste. Exploratory trenching was not performed in the southern area of the subject site. Also, groundwater sampling was not performed in the northern portion of the subject site, which appeared to be the most heavily impacted area based on the results of exploratory trenching. TBG was not tasked with detennining the type, total volume, depth, and boundaries of the solid waste disposal areas throughout the subject site as part of this limited Phase II ESA. Further assessment may be warranted if additional data is needed to further delineate the exact location, depth and volume of solid waste and to evaluate groundwater quality in the disposal area located in the northern section of the site. If the site is to be developed or disposal areas disturbed TBG recommends that that the procedures outlined in FDEP Guidance for Disturbance and Use of Old Closed Landfills or Waste Disposal Areas in Florida dated April 2, 2019, be followed.
