1.0 Introduction

Terracon has completed Limited Phase II Environmental Site Assessment (Phase II) activities at the at 1317 N Magnolia Avenue and 23 NE 13th Street in Ocala, Marion County, Florida (the site). The work was performed in accordance with the Authorization for Phase II ESA dated

August 9, 2023, and our Professional Brownfields Services Contract GRM/220582 dated

December 20, 2022.

The site is currently 1.7-acres of undeveloped land and consists of Marion County Property

Appraiser Parcel Nos. 26297-000-00 and 26298-000-00. The site is improved with a paved parking area on the southwest quadrant and utilities.

The site has been occupied by residential and commercial structures since 1930. The site was occupied by a furniture warehouse from 1930 to approximately 1960; a filling station was located at the southwest corner by 1930 through the mid-1940s; multiple residential homes until the 1970s, and a lumber storage company and associated warehouses from the mid-

1940s through 2000. According to a representative from the City of Ocala, the lumber storage facility mainly operated across the street to the west and the site consisted of offices and lumber warehouse storage. The on-site structures were razed by 2013 and the site has since remained vacant.

The objective of this Limited Phase II was to assess the recognized environmental conditions

(RECs) identified in the Terracon Phase I ESA dated July 12, 2023 (Terracon Project No.

EQ237012, Task B). This report details the Phase II activities conducted on the site. A

Topographic Vicinity Map is included as Exhibit 1 and the site features are shown on the Site

Diagram included as Exhibit 2. Below are the RECs that were investigated.

REC/Site Concern Description

Former on-site filling station

Potential for a petroleum product release associated with a historical gas station located at the southwest corner of the site.

Former on-site

Underground Storage

Tanks (USTs)

Lack of regulatory tank closure documentation and the potential for a historical petroleum product release (Note: Additional information obtained from the Florida Department of Environmental Protection

(FDEP) after the completion of the Phase I ESA indicated the tanks formerly held trichlorethylene (TCE).)

Former USTs at

Chevron Station

(northwest adjoining property)

Lack of regulatory tank closure documentation and the potential for a historical petroleum product release.

3.0 LSI INVESTIGATION

A subsurface geophysical survey utilizing Ground Penetrating Radar (GPR) was completed on

October 16, 2023. Soil and groundwater assessment activities were conducted from October

17, 2023, through October 18, 2023. A Field photo log is provided in Appendix A.

4.0 Utility Locates and GPR Survey

As discussed above, Terracon submitted a locate ticket using Florida’s Sunshine 811 service, to locate public and private utilities in proximity to and within the right-of-way of the site.

Terracon did not initiate subsurface work prior to the completion of the cleared 811 locate ticket. Terracon subcontracted GeoView who performed the ground penetrating radar (GPR) subsurface investigation and marked surface locations of subsurface anomalies that could indicate the potential presence of utilities in the proposed screening/sampling locations.

Subsurface anomalies were not identified within at the prescribed sampling locations.

GeoView also performed the GPR subsurface investigation of potential onsite USTs and three

USTs were located, and the suspect UST locations are provided on Exhibit 2.

5.0 Soil Sample Collection and Analyses

5.1.1 SOIL SCREENING

Soil samples for field screening were collected from boring locations shown on Exhibit 2.

Field decontamination and soil sample collection procedures were consistent with the Florida

Department of Environmental Protection’s (FDEP’s) Standard Operating Procedures for Field

Activities, DEP-SOP-001/01, FC1000 and FS3000.

On October 17, 2023, a stainless-steel hand auger and Geoprobe® direct-push technology

(DPT) were used to advance two soil borings (SB-1 through SB-9) at the site. The borings

SB-1 though SB-4 were positioned within the approximate location of the former on-site filling station (southwest corner of the site) and the additional five soil borings (SB-5 through SB-

9) were positioned on the northern portion of the site to evaluate the potential for impacts associated with historical site use and the former USTs.

Soil organic vapor headspace measurements were performed at each soil boring to screen for volatile organic vapors using an organic vapor analyzer (OVA) equipped with a photo ionization detector (PID). Physical indications of potential contaminant impacts were noted such as odor, sheen, and/or discoloration. Soil screening was performed from the surface to

0.5-foot below ground surface (bgs), and thereafter at 1-foot depth intervals to the groundwater table. Soil OVA headspace measurements were collected in general accordance with Chapter 62-780.200(17), Florida Administrative Code (FAC). No evidence of organic vapors were identified within the soil collected and observed through field measurements.

In general, soils consisted of grey, tan, orange and black silty sands from ground surface to approximately 5-feet bgs, where brown and orange clays were then encountered from approximately 5 to 20-feet bgs. The water table interface was encountered between approximately 6 feet bgs on the northeast portion of the site and 10 to 14 feet bgs on the western and southern portions of the site.

Soil boring locations are shown on Exhibit 2. Boring Logs which provide a summary of the

OVA readings are included in Appendix A. Field decontamination and soil sample collection procedures were consistent with the FDEP’s Standard Operating Procedures for Field

Activities, DEP-SOP-001/01, FC1000 and FS3000.

5.1.2 SOIL SAMPLE COLLECTION

On October 17, 2023, soil samples were collected from the prescribed soil boring locations within the vadose zone at each location. SB-1, SB-3, and SB-5 were collected at a 12-foot depth interval (12-feet bgs), SB-2, SB-7, SB-9 were collected at 11-foot bgs, SB-4 was collected at 14-feet bgs, SB-6 was collected at 10-feet bgs and SB-8 was collected at 6-feet bgs, all of which were within the vadose zone approximately 1-foot above the water table in their respective locations. Soil samples were collected in laboratory-supplied containers, labeled, and packed in coolers on wet-ice for delivery using chain-of-custody procedures to

Southern Research Laboratories, Inc (SRL).

The soil samples collected on October 17, 2023, were submitted for laboratory analysis of lead by EPA Method 6010B, polycyclic aromatic hydrocarbons (PAHs) by EPA Method 8270, volatile organic compounds (VOCs) by EPA Method 8260 and total recoverable petroleum hydrocarbons (TRPH). Laboratory analytical reports and chain-of-custody records are provided in Appendix B. Results are discussed in Section 3.0.

5.2 EQUIPMENT DECONTAMINATION AND QUALITY ASSURANCE

Non-expendable soil sampling equipment was decontaminated at the beginning of each sampling event and decontaminated between each soil boring by hand-scrubbing in a

Luminox and water solution and rinsed with de-ionized (DI) water.

6.0 Groundwater Sample Collection and Analyses

On October 18, 2023, Terracon’s drilling subcontractor, JAEE, also used Geoprobe® DPT methodology to install two temporary monitoring wells (TMW-1 through TMW-2). Temporary shallow monitoring well (TMW-1) was installed at the southwest corner of the site (at the SB-

2 soil boring location) to evaluate groundwater associated with the former on-site filling station and temporary monitoring well (TMW-2) was installed on the northwest corner of the site to evaluate potential impacts from the former off-site and upgradient filling station.

Additionally, JAEE, also used Geoprobe® DPT methodology to install a series of five discrete sample well points (DSP-1 through DSP-5) across the site to evaluate for potential chlorinated solvent impacts associated with the former on-site USTs.

TMW-1 through TMW-2 were installed to a terminal depth of approximately 23-feet bgs respectively and were constructed of 10 feet of 1-inch diameter, 0.010-inch machine slotted polyvinyl chloride (PVC) well screen with a 20/30-graded silica sand filter pack and approximately 15 feet of 1-inch diameter PVC riser extending above ground through the surface. The temporary monitoring wells were developed by over pumping, and the purge water was spread on the adjoining, impervious land surface to evaporate. Stability parameters including pH, temperature, conductivity, dissolved oxygen, and turbidity were monitored during the groundwater purging and sampling procedures. The Well Construction and

Development Logs are included in Appendix A. The temporary monitoring wells were removed, and the boreholes were abandoned immediately following the collection of groundwater samples.

Discrete sample well point samplers were advanced to an approximate depth of 25-feet bgs at DSP-1 through DSP-5. Groundwater samples were collected directly from the drill-rod and well screen assembly following proper development and purging. Following the collection of the upper interval water sample, well point DSP-2 was further advanced to an approximate depth of 35-feet bgs for the collection of another discrete sample to determine if chlorinated solvents are present at a deeper interval based on the potential for a nearby USTS with TCE to impact the site. DSP-3 was converted into a temporary piezometer (PZ-1) following the sampling protocol for use in estimating groundwater flow direction.

Groundwater sampling was conducted in general accordance with DEP-SOP-001/01, FS 2200 protocol. Groundwater samples for TMW-1 and TMW-2 were submitted for laboratory analysis of lead (total and dissolved) by EPA Method 6010B, PAHs by EPA Method 8270, VOCs by EPA

Method 8260 and TRPH by FL-PRO. All discrete sample well points were analyzed for VOCs

EPA Method 8260. The laboratory analytical reports and chain-of-custody records are provided in Appendix B. Results are discussed in Section 5.0. The temporary monitoring well locations are shown on Exhibit 2.

6.1.1 GROUNDWATER ELEVATION

On October 17, 2023, the depth to groundwater was measured to calculate groundwater elevations. These measurements were only collected from TMW-1, TMW-3 and PZ-1. The top of casing elevations were field surveyed to an arbitrary elevation datum and the depth–to– groundwater measurements were converted to groundwater elevations in order to evaluate groundwater flow direction. The measurements for the top of casing elevations, depth to groundwater, and groundwater table elevations are displayed on Table 1. The groundwater table elevations for three of the wells were plotted on Exhibit 3. Based on the October 17, 2023, measurements, the shallow aquifer groundwater flow direction in generally to the to the north.

7.0 Summary of Analytical Results

The following sections summarize the soil and groundwater analytical results from the Limited

Phase II. Constituent concentrations were compared to the State of Florida’s Chapter 62-777, FAC, Tables 1 and 2 containing Direct Exposure Residential and Commercial/Industrial Soil

Cleanup Target Levels (SCTLs), Leachability based on Groundwater Criteria SCTLs, and

Groundwater Cleanup Target Levels (GCTLs). Additionally, groundwater laboratory data were also evaluated with respect to Natural Attenuation Default Concentrations (NADCs) listed in

Table 5 of Chapter 62-777, FAC.

7.1 SOIL ANALYTICAL RESULTS

A summary of the soil analytical results is provided in Table 2. Laboratory analytical reports and chain-of-custody records are provided in Appendix B. Soil analytical results are demonstrated on Exhibit 4.

Laboratory analytical results for soil samples reported all concentrations for PAHs, TRPH and

VOC results below applicable SCTLs and below laboratory method detection limits (MDLs) as non-detected and are associated with a U-qualifier by the laboratory. SB-5 also reported lead as non-detected and is associated with a U-qualifier.

Lead was reported as detected in all samples and results consisted of the following SB-1 27.2 milligram/kilogram (mg/kg), SB-2 8.6mg/kg, SB-3 9.5mg/kg, SB-4 7.2mg/kg, SB-5XXmg/kg, SB-6 15.8mg/kg, SB-7 8.7mg/kg, SB-8 2.1mg/kg and SB-9 19mg/kg.

7.2 GROUNDWATER ANALYTICAL RESULTS

A summary of the groundwater analytical results is provided in Table 3. Laboratory analytical reports and chain-of-custody records are provided in Appendix B. Groundwater analytical results are demonstrated on Exhibit 5.

Laboratory analytical results for all groundwater samples collected reported lead, PAHs, TRPH and VOC results as non-detected and are associated with a U-qualifier by the laboratory.

7.3 CONCLUSIONS

Based on the results of this investigation, three suspect USTS remain in site, soil and groundwater impacts were not identified within tested samples and shallow groundwater flow at the site is directed to the north.

7.4 RECOMMENDATIONS

Based on the above findings, it is recommended to complete a formal UST closure assessment and update Storage Tank Facility Registration Forms [DEP form 62-761.901(2)] for FDEP and

City of Ocala Public Works recording.

9.0 QUALITY ASSURANCE/Quality control

The Generic QAPP and SSQAPP Addendum for this project set forth the procedures and methods for data collection, and specific procedures and adjustments necessary to maintain data quality to support the project decision: can the site or areas within the site be considered for redevelopment without environmental remedy? This assessment required both field and laboratory checks to monitor conformance to project quality objectives.

SITE-SPECIFIC CORRECTIVE ACTIONS

A field methods audit was not conducted during the fieldwork for this site. During the recent fieldwork, assessment practices were generally conducted in a method consistent with the methodology of the SSQAPP and FDEP SOPs.

QUALITY CONTROL PARAMETERS

To assess whether quality assurance objectives for this project have been achieved, the following quality control (QC) parameters were considered: precision, accuracy, representativeness, comparability, completeness, and sensitivity. Laboratory analytical reports and chain-of-custody records are provided in Appendix B.

PRECISION AND ACCURACY

Precision

Precision is typically evaluated using relative percent difference (RPD). The laboratory analyzed and evaluated Laboratory Control Sample (LCS) and Matrix Spike (MS) duplicates to assess analytical precision. The LCS RPDs were reported within acceptable limits within

RSL reports 2310037 and 2310046.

A summary of individual exceptions can be found the laboratory report case narrative. For solid matrices, duplication of non-homogeneous samples (i.e. soils) is difficult due to matrix interference, which commonly results in elevated RPDs. In Terracon’s opinion, the RPDs reported outside laboratory precision limits have not impacted the decision.

Accuracy

Accuracy is evaluated using a percent recovery measured in spiked and un-spiked samples.

Accuracy is a function of the laboratory method, and parameters regarding accuracy are included in the report provided by the laboratory. The laboratory analyzed and evaluated LCS and MS recoveries to assess analytical accuracy. Laboratory accuracy controls were documented in accordance with the laboratory’s QA Manual (included as an appendix to the

Generic QAPP).

Trip blanks were planned and requested of the laboratory. Potential impacts to accuracy due to sample transport conditions were not documented by the laboratory. One equipment blank was planned as part of this assessment to be collected during soil sample activities. No analytes were reported in the equipment blank (Trip Blank) within RSL Reports 2310037 and

2310046. In Terracon’s opinion, field decontamination procedures have not impacted sample accuracy. Since the equipment blank reported no analyte detections, the equipment blank can be considered as an evaluation of sample transport conditions from time of collection to analysis.

Sample holding times were met for all constituent analyses.

MS recoveries and LCS recoveries were reported within QC limits within RSL Reports 2310037 and 2310046.

Representativeness

Terracon has evaluated the representativeness of the Phase II ESA activities to document the degree to which the sample data accurately and precisely represents a characteristic of a population, parameter variations at a sampling point, or an environmental condition. Review of field methods and procedures indicated that sample collection, handling, and transportation were conducted in accordance with the SSQAPP. Review of analytical results indicates that the analytical data is generally uniform and consistent between sampling points.

Completeness

Samples were not collected as planned in the SSQAPP. Three temporary monitoring wells did not produce water for sampling and were terminated after multiple attempts to purge and sample groundwater. All samples that were collected were submitted and analyzed according to the chain-of-custody.

Comparability

To produce comparable data, the units specified for analytical results obtained during the field activities are consistent throughout this project and standardized analytical methods have been used for each parameter.

Sensitivity

Sensitivity is an instanced measure of a particular set of sample detection limits against the applicable CTL. Sufficient sensitivity implies that for a given analyte, detection limits were low enough to evaluate a “non-detect” versus the CTL. Conversely, insufficient sensitivity implies that even though a given analyte may not be detected above a CTL, the detection limit is elevated above the CTL. In such a case, it is unknown if the analyte is present at the site above a CTL.

Terracon reviewed the laboratory reports generated during this assessment. Laboratory quantitation limits were sufficient to report concentrations below the applicable standards for the analytes.

In cases where the laboratory is unable to detect to the CTL for a specific analyte, Chapter

62-780.650(1)(d), FAC, establishes the CTL as the best achievable detection limit (i.e., the laboratory’s PQL).

LABORATORY DATA EVALUATION

The laboratory completed validation and verification of laboratory processes and data and delivered a laboratory report to Terracon for review. The laboratory report and the QC information contained therein documents compliance to the SSQAPP Addendum.

Data were evaluated with respect to applicable CTLs as detailed in the Generic QAPP Section

A-5.2. The following CTLs were applied: Chapter 62-777, FAC Residential Direct Exposure

SCTLs, Commercial/Industrial Direct Exposure SCTLs, Leachability SCTLs based on groundwater criteria, GCTLs, and NADCs.

Data qualifiers were used by the contract laboratory when presenting data in the laboratory reports included in Appendix B. These qualifiers are presented at the end of each laboratory report.

Data usability determination is also a part of data evaluation. After data quality has been assessed, and the analytical data has been reviewed and qualifier codes have been applied, these data must be individually identified and assessed for usability. Sample data (both with and without qualifier codes) may be generally spoken of as either qualitative (restricted), quantitative (unrestricted), or unusable. Within any matrix, it is likely certain samples may have parameters that require qualifier codes. A discussion of these qualifier codes for each level is provided below if warranted.

QUALITATIVE DATA – RESTRICTED DATA

Qualitative data are often referred to as Restricted Data. All screening data is considered

Restricted Data. Screening data may not be considered as Unrestricted Data and cannot be used to make site management decisions. Restricted data may also include “I” coded laboratory data. These data are considered to be an estimated quantity, i.e., a presence or absence value. Any sample data receiving an “R” qualifier code, “N” code, “J” qualifier, or an unexplained “B” qualifier code was not classified as Restricted Data and was considered unusable for making site decisions (none of these codes were identified). Data with a “I” code were not automatically classified as qualitative data only; these data were considered as

Unrestricted Data (quantitative) depending on bias and were evaluated on a case by case basis. Data reported with a “U” code is classified as Unrestricted Data, provided the detection limit was not above an applicable CTL for that analyte.

All field-instrument-derived data was accepted as Restricted Data only and was not considered for inclusion as Unrestricted Data.

QUANTITATIVE DATA – UNRESTRICTED DATA

Quantitative data are referred to as Unrestricted Data. Only data meeting field and analytical data usability requirements may be classified as Unrestricted Data. This requires that all quality assurance parameters have been satisfied, including quality control criteria. Only data that were found to be analytically valid and passed all criteria for Unrestricted Data were considered for classification as Unrestricted Data. These data are considered definitive and may be used for any purpose.

In reviewing the laboratory results, several analytes are reported as detections with “I” data qualifiers, indicating the reported value is an estimate reported within the 95% confidence interval. These compounds were detected above the laboratory Method Detection Limit (MDL), but below the Practical Quantitation Limit (PQL). The MDL is the lowest concentration at which an analyte can be detected in a sample by the particular laboratory method used. “Detected” indicates that the analyte can be distinguished from the blank with reasonable certainty.

Results above the MDL can be distinguished from the blank and fall within applicable standard curves. For the purposes of this assessment, all “I” and “J” qualified data are considered acceptable for making site management decisions as these data are not the sole determinant of “clean.” Qualified data meeting acceptance criteria for sensitivity has been considered against applicable CTLs in evaluating extent of impacts.

Data for individual analytes which fail sensitivity requirements would normally be rejected;

however, Chapter 62-780.650(1)(d), FAC allows that these data be acceptable for use as

Unrestricted Data. All remaining laboratory-derived data are accepted as Unrestricted Data.

Individual data failing project-use criteria are not the sole determinant of clean for any area of the site and may be viewed as qualitative support for the entire data set.

NATURAL ATTENUATION DEFAULT CONCENTRATIONS

Natural attenuation is defined by the EPA as “a variety of physical, chemical, or biological processes that, under favorable conditions, act without human intervention to reduce the mass, toxicity, mobility, volume, or concentration of contaminants in soil or groundwater”.

Use of monitored natural attenuation as a remediation strategy involves a formal regulatory process to verify that natural processes are effective to complete site cleanup. Chapter 62-

777, FAC NADCs were created as a rule of thumb procedure to simplify the technical evaluation to justify natural attenuation monitoring as a viable strategy at the conclusion of site assessment. Concentrations of COCs below NADCs may qualify for natural attenuation as a possible remediation strategy to achieve site cleanup.
