Monitoring Well Installation
On March 13-15, July 17-18, October 18-19, 2017 and July 31 – August 1, 2018, ECS personnel supervised
Earth Tech Drilling, Inc. (ETD) during the installation of groundwater monitoring wells utilizing sonic core
(SC) technology. The intermediate wells (“D”) were constructed by installing a temporary 8” override
casing sonic to a depth of thirty-three (33) feet below land surface (ft-BLS) and the wells were completed
to forty (40) ft-BLS with five (5) feet of screen. The deep wells (“DD”) were constructed by installing a
temporary 8” override casing sonic to a depth of forty-eight (48) feet below land surface (ft-BLS) and the
wells were completed to fifty-five (55) ft-BLS with five (5) feet of screen. The wells installed and dates
are as follows:
July 17-18, 2017 – HSW-54D, HSW-55D & HSW-56D
October 18-19, 2017 – HSW-57D, HSW-58D, HSW-59D, HSW-60D & HSW-61DD
July 31 – August 1, 2018 – HSW-62D, HSW-63D & HSW-64D (offsite)
Soil samples collected during monitoring well installation were screened for lithology and subjected to a
headspace analysis with an Organic Vapor Analyzer equipped with a Photo Ionization Detector (OVA-
PID). All sampling activities were completed in accordance with the Standard Operating Procedures
(February 2004) adopted by the FDEP. A total of ten (10) 55-gallon drums of drill cuttings were generated
during the drilling activities, then collected and disposed by Clark Environmental. The waste manifests are
included in Appendix D. Soil boring logs, well construction logs and well completion reports are included
in Appendix B. Field notes and a photographic log are included in Appendix C. Soil OVA screening
results are summarized in Table 1. The monitoring well locations are depicted in Figure 2.
Water Table Elevation Data
Prior to each groundwater sampling, depth-to-water (DTW) was measured in select monitoring wells using
an electronic, water-table interface probe. The DTW measurements, well casing elevations and
corresponding groundwater elevations are summarized in Table 2. Groundwater table elevation contour
maps based on March 2017 through August 2018 groundwater elevation data are provided as Figures 3A
through 5.
Groundwater Analytical Data
Groundwater sampling was performed at the site on March 28-30, July 24-25, October 26, 2017 and August
13, 2018. All wells were purged and sampled per procedures outlined in FDEP-SOP-001/01, Florida
Statutes (FS) 2200 Groundwater Sampling (with subsequent revisions and clarifications). All groundwater
samples were collected into laboratory-supplied, pre-preserved containers and submitted to Advanced
Environmental Laboratories, Inc. in Jacksonville, Florida using proper chain-of-custody protocol. Samples
were analyzed for multiple analytes by one or more of the following analytical methods: Environmental
Protection Agency (EPA) Method 8260B was utilized to analyze for benzene, toluene, ethylbenzene, total
xylenes (BTEX) and methyl tertiary-butyl ether (MTBE), volatile organic halocarbons (VOHs) including
1,2-dichloroethane (1,2-DCA), 1,2,4- & 1,3,5-trimethylbenzene; EPA Method 504.1 was utilized to analyze
for 1,2-Dibromoethane (EDB); and EPA Method 8270D by Simultaneous Ion Monitoring (SIM) was
utilized to analyze for polycyclic aromatic hydrocarbons (PAHs). The laboratory analytical reports and
groundwater sampling logs for the 2017-2018 sampling events are included in Appendix A.
Laboratory analytical results from the 2017-2018 sampling events indicate that multiple analytes from
multiple wells in the shallow and intermediate zones exceeded their respective Groundwater Cleanup Target
Levels (GCTLs) and Natural Attenuation Default Concentrations (NADCs) for Source and/or Perimeter
Wells. No analytes exceeded any GCTLs in the deep zone. Recent groundwater analytical data are
summarized in Tables 3A and 3B depicted on Figures 6A through 7C. Isoconcentration maps for select
analytes in the shallow and intermediate zones from the 2017-2018 sampling events are presented as
Figures 8A through Figure 9F.
CONCLUSIONS
" ECS personnel supervised Earth tech Drilling, Inc. during the installation of seventeen (17)
monitoring wells via sonic core (SC) technology on and off-site from March 2017 through August
2018;
2017 through August 2018;
" Laboratory analytical results from the 2017-2018 sampling events indicate that multiple analytes
from multiple wells in the shallow and intermediate zones exceeded their respective GCTLs and
NADCs for Source and/or Perimeter Wells;
" The horizontal and vertical extent of dissolved-phase hydrocarbon contamination at the site appears
to be delineated.
RECOMMENDATION
" Based on the data collected during the 2017 – 2018 soil and groundwater assessment, ECS
recommends a teleconference to discuss remediation options.

Only constituents above GCTL are represented in this table.
NA Not analyzed
Bold + Italics = concentration detected and above NADC levels.
D = Diluted
I = value is between the laboratory method detection limit and the laboratory practical quantitation limit.
L = Off-Scale high; exceeds the linear range or highest calibration standard.
V = value indicates the analytes was detected in both the sample and the associated method blank.
b Result is from Run #2
