EXECUTIVE SUMMARY
This report summarizes the investigatory activities performed by Geo Strata Environmental Consultants,
Inc. (Geo Strata), during a Phase II Environmental Site Assessment (ESA) conducted within three distinct
project areas (Area 1, Area 2, and Area 3). Area 1 includes the western portion of the Henry B. Gonzalez
Convention Center (HBGCC); Area 2 is comprised of a corridor located south of the Lila Cockrell Theater and north of the HBGCC 2001 Expansion; and Area 3 is comprised of areas east of the HBGCC
2001 and Grand Hyatt Expansions, including portions of E. Market Street, S. Bowie Street, the former
San Antonio Water System (SAWS) headquarters property, Hemisfair Memorial Garden, and the
Alamodome pedestrian walkway. Currently the City of San Antonio (COSA) is proposing demolition of
the original western portion of the convention center, along with further expansion to the east of the
HBGCC 2001 and Grand Hyatt Expansions. Authorization to perform the Phase II work was provided by
Hunt-Zachry, a Joint Venture (Hunt-Zachry).
The Phase II ESA was conducted to investigate the potential presence or absence of environmental
contaminants in the subsurface associated with recognized environmental conditions (RECs), including
Texas Commission on Environmental Quality (TCEQ) voluntary clean-up (VCP), leaking petroleum
storage tank (LPST), and underground storage tank (UST) facilities; historic auto repair, brake servicing, filling stations, laundries and cleaners, sign and paint shops, factories and warehouses, auto sales and
truck yards, San Antonio Coca Cola Bottling Company, mirror works, printing, dry cleaning, a tannery,
machine shop; and the historic utilization of fill materials within the project area.
Prior to commencing drilling activities, Geo Strata personnel mobilized to mark the locations of the proposed soil borings. Texas One Call and SAWS were contacted to locate and mark any subsurface
utilities within the proposed project area. The City Public Works permit office was also contacted to
obtain right-of-way (ROW) Use Permits for several soil borings located within Area 1 and Area 3.
Traffic management within the ROWs was provided by American Signal Equipment Company.
Two Texas-licensed Geoscientists employed by Geo Strata, Ms. Cheri Krieg and Mr. Joel Stevens, and a
drilling crew from Vortex Drilling of San Antonio, Texas, mobilized to the site on July 15, 16, 17, 18, and
19, 2013. A total 28 soil borings were proposed for advancement within the three project areas (SB-1
SB-2, SB-4, SB-5, SB-6, SB-8 through SB-11, SB-12a through SB-12g, SB-15, SB-20, SB-21, SB-25,
SB-26, SB-28, SB-32 through SB-34, SB-37, SB-39, and SB-40). Soil borings SB-1 and SB-5 could not
be completed due to auger refusal. Completion of soil borings SB-6, SB-11, and SB-28 were postponed
due to concerns regarding underground utilities and interference with on-going convention activities since
they are located within the existing building footprint. Additionally, soil boring SB-39 was drilled twice
(SB-39a and SB-39b, first and second attempts, respectively), due to auger refusal during the first
attempt. All of the completed soil borings were advanced using a heavy-duty trackprobe rig.
During the drilling activities, soil samples were field screened over 2.5-foot intervals for the presence of
organic vapors utilizing a portable photoionization detector (PID). Elevated organic vapors (exceeding
100 ppm) were not detected in any of the samples.
Based upon the type of REC, the field screening results and the proposed work to be completed, selected
soil samples were analyzed for total petroleum hydrocarbons (TPH), Resource Conservation and Recovery Act (RCRA) 8 metals, and volatile organic compounds (VOCs). Analytical results were
compared to Texas Commission on Environmental Quality (TCEQ), Texas Risk Reduction Program
(TRRP) Protective Concentration Levels (PCLs) and Texas Specific Background Concentrations

ingestion protective concentration levels (PCLs) or TXSBC in all but two of the borings. With the
exception of barium concentrations in SB-25, all metal, TPH, and VOC concentrations in soil measured
below health-based levels for the construction worker.
Groundwater analytical results collected from 12 soil borings (SB-2, SB-4, SB-12a through SB-12e, SB-
12g, SB-20, SB-21, SB-33, and SB-37) were compared to TRRP groundwater ingestion PCLs to determine whether or not impacts existed in excess of regulatory levels. All analyzed samples were
reported as non-detect or below regulatory PCLs for metals, TPH, and VOCs.
Based on the findings of this assessment, Hunt-Zachry should provide notification to the property owner
indicating that metals concentrations (arsenic, barium, lead, mercury, and selenium) have been detected
above TRRP PCLs in the soils. Following notification by Hunt-Zachry, it is recommended that the
property owner should notify the TCEQ regarding the results of this investigation, and to discuss the next
appropriate course of action.
In addition, the following recommendations are offered to Hunt-Zachry during construction and
demolition activities:
Since arsenic, barium, lead, mercury, and selenium concentrations exceeded regulatory levels in the many
of the samples collected from soil borings advanced during this Phase II assessment, it is recommended
that all soils excavated during this project within the study area (with the exception of soils in the vicinity
of SB-25, which exceeded health based levels and therefore, must be disposed off-site) should be either
reused on-site, or characterized, manifested and disposed off-site at an approved landfill. Laboratory analytical result obtained during this assessment indicated the soils may be classified as Class II waste.
However, additional sampling and analysis may be required by the landfill, based upon the volume of
soils requiring disposal. Initial communications with representatives from the Republic Services landfill
indicated that it is possible the analytical data collected during this Phase II assessment, along with results
gathered during the COSA Market Street Realignment Phase II ESA (see Appendix E) could potentially be utilized to complete the waste characterization profile. All soils impacted by metals exceeding
regulatory levels must be considered contaminated, and should not be transported off-site and treated as
clean fill material.
In addition, since soils are impacted by metals exceeding regulatory levels, it is recommended that Hunt-
Zachry consult with an environmental health and safety professional to develop a Health & Safety plan,
which will provide guidance necessary to protect the construction workers during the proposed expansion
project. At a minimum, the Health & Safety Plan should provide guidance regarding issuance and use of
personal protective equipment, and appropriate health and safety training for each of the workers that may
be potentially exposed to the metals contamination during the normal course of their work.
Since sufficient groundwater analytical data was collected from the upper groundwater-bearing zone in
Areas 2 and 3 to properly assess potential groundwater impacts, groundwater encountered between
surface and 30 feet may be treated as non-impacted. An exception to this rule would be if the
construction workers observe evidence of contamination in the field, such as an unusual odor or oily
sheen on the groundwater surface. Since limited groundwater data was collected in Area 1, additional
sampling of groundwater in Area 1 will be required to determine if the water is impacted. Therefore, it is recommended that shallow groundwater in Area 1 (if encountered during construction) should be
evacuated into a storage tank on-site, sampled and characterized to determine if it has been impacted by
historic business operations, or leachate from imported fill materials.

Finally, several areas (SB-6, SB-11, and SB-28) within the HBGCC building footprint could not be
assessed, due to underground utility concerns and access limitations related to the on-going activities
within the convention center. Further assessment and sampling of these areas is recommended following
demolition of the HBGCC.
1.0 PROJECT BACKGROUND
The San Antonio Convention Center (later named the Henry B. Gonzalez Convention Center (HBGCC)
was constructed as part of Hemisfair in 1968. The convention center was later expanded to the south
during 1986 (HBGCC 1986 Expansion); to the east during 2001 (HBGCC 2001 Expansion); and further
expanded to include the Grand Hyatt Convention Center Hotel and Condominiums (Grand Hyatt
Expansion) during 2008. Currently the City of San Antonio (COSA) is proposing demolition of the
original western portion of the convention center, along with further expansion to the east of the HBGCC
2001 and Grand Hyatt Expansions. The western portion of the Henry B. Gonzalez Convention Center
(HBGCC) is comprised of an approximately 267,511 square foot multi-story building. A Project Area
Vicinity Map is provided as Figure 1 in Appendix A. Hunt-Zachry, a Joint Venture (Hunt-Zachry) has
been contracted by COSA to perform the Convention Center Expansion Project.
In January 2013, Hunt-Zachry contracted with Geo Strata to complete a Phase I Environmental Site
Assessment (ESA) of the three distinct project areas (Area 1, 2, and 3). All three areas are located with
the Hemisfair Park area. Area 1 includes the western portion of the HBGCC and HBGCC 1986
Expansion. Area 2 is comprised of a corridor located south of the Lila Cockrell Theater and north of the
HBGCC 2001 Expansion. Area 3 is comprised of areas east of the HBGCC 2001 and Grand Hyatt
Expansions, including portions of E. Market Street, S. Bowie Street, the former San Antonio Water
System (SAWS) headquarters property, Hemisfair Memorial Garden, and the Alamodome pedestrian
walkway. A Site Plan depicting the general layout of the project area is below as Image 1.
Area 1
Area 2
Area 3
The Phase I ESA identified three high risk (environmental impacts already documented) and 38 potential
risk recognized environmental conditions (RECs) located both on and off-site. The majority of the RECs
were associated with historic utilizations which no longer exist, including auto repair, brake servicing,
filling stations, laundries and cleaners, sign and paint shops, factories and warehouses, auto sales and
truck yards, San Antonio Coca Cola Bottling Company, mirror works, printing, dry cleaning, a tannery,
and machine shop. The report also identified the historic utilization of fill materials within the Hemisfair
Park area; two Voluntary Clean-up Program (VCP) facilities (HBGCC 2001 Expansion VCP Facility
#391; the Grand Hyatt Expansion VCP Facility #1876; and specifically, a Leaking Petroleum Storage
Tank (LPST) facility located at the Lila Cockrell Theatre (LPST #111868); and several aboveground
storage tank (AST) and underground storage tank (UST) facilities.
Based upon the results of the Phase I ESA, Geo Strata recommended review of all available
environmental reports and documents prepared for the Hemisfair area and performance of a Phase II ESA,
prior to commencing construction of the Convention Center Expansion Project.
2.0 HISTORICAL DOCUMENT REVIEW AND PRE-PLANNING ACTIVITIES
Per Hunt-Zachry approval, Geo Strata obtained and reviewed available environmental documents
associated with the following facilities and/or projects within the HBGCC project area, to obtain
additional information regarding the RECs identified during the Phase I ESA:

Based upon reviews of the aforementioned documents, a scope of work (SOW) was developed to include
the advancement of a maximum of 28 soil borings at locations within the three project areas. The
HBGCC Proposed Soil Boring Map is provided as Figure 2 in Appendix A. Based upon
correspondence with Hunt-Zachry personnel regarding the location and maximum depth of the proposed
improvements, the borings were initially proposed to depths between 10- and 30-ft below ground surface
(bgs) to evaluate potential impacts to subsurface soils and groundwater (if encountered) in areas requiring
building demolition (Area 1), construction (Area 2 and 3), and overexcavation prior to construction (Area
3). A Phase II Summary Boring and Analytical Summary Table identifying the boring IDs and
locations, location selection rationale, and proposed laboratory analysis is presented following the Soil
Boring Location Map in Appendix A.
At the request of Hunt-Zachry, the SOW was revised prior to mobilizing to the field to ensure that each of
the soil borings proposed within Area 3 were advanced until encountering the Navarro Clay, a confining
unit separating surface soils from the Edwards Aquifer, to ensure that each boring properly evaluated all
fill materials brought to the site in the past. This was necessary, since design plans called for construction
of structural piers extending to approximately 60-70 feet below grade in Area 3. Per Hunt-Zachry
approval, all of the soil borings were proposed for advancement approximately 5- to 10-ft into the native
confining clays, and included collection of soil samples from the surface soils, the capillary fringe (if
groundwater was encountered), and the total depth of the boring. Due to the increased depth of each of the
soil borings, the drilling schedule was also expanded from three to five working days.
Additionally, plans to advance three borings within the HBGCC western building footprint were placed
on hold, due to concerns regarding underground utilities and interference with on-going convention center
activities.
3.0 OBJECTIVES OF INVESTIGATION ACTIVITIES
The Phase II ESA was conducted to investigate the potential presence or absence of environmental
contaminants in the subsurface, associated with historical business activities, and the utilization of fill
materials within the project area.

4.0 SCOPE OF INVESTIGATION ACTIVITIES
4.1 Preliminary Planning
Prior to mobilizing to the field, Geo Strata coordinated with Hunt-Zachry and HBGCC personnel to
obtain access and to coordinate optimal times for work completion, during on-going conferences,
conventions, and tourism within the three project areas.
Geo Strata and Vortex also prepared and submitted the right-of-way (ROW) Use Permit to the City Public
Works permit office. The ROW package included a site map to show the proposed boring locations along
with the appropriate traffic management plan, provided by American Signal Equipment Company, the
company that was subcontracted to provide traffic management services. Per the Permit Office,
pedestrian walkway closures and reduced field activity hours were required for two soil borings located
within the Alamodome walkway and four soil borings located along S. Alamo Street.
4.2 Utility Locates
Prior to commencing drilling activities, Geo Strata personnel mobilized to mark the locations of the
proposed soil borings. Texas One Call and SAWS were contacted to locate and mark any subsurface
utilities within the proposed project area.
During field activities, Geo Strata coordinated field meetings (where possible) with the respective utility
locators. With the exception of the three borings within Area 2 (SB-2, SB-4, and SB-32), all of the
proposed soil boring locations were checked by each of the utility companies to ensure that proper
clearance was obtained. Underground utilities in the vicinity of SB-2, SB-4, and SB-32 were also verified
by Hunt-Zachry personnel. In general, utilities were marked within 5 to 10-feet of the proposed soil
borings, allowing the borings to be moved in the event conflicts were discovered. In several areas, utility
conflicts required the boring locations to be relocated.
4.3 Drilling Activities
4.3.1 Environmental Borings
Two Texas-licensed Geoscientists employed by Geo Strata, Ms. Cheri Krieg and Mr. Joel Stevens, and a
drilling crew from Vortex Drilling of San Antonio, Texas mobilized to the site on July 15, 16, 17, 18, and

A total of 23 environmental soil borings were advanced as part of the investigation. The completed soil
boring depths ranged from 20 to 35-ft bgs. The soil borings were advanced using a heavy-duty
trackprobe rig, which provided the ability to drill in grassy areas, along slopes (if necessary), and in
parking lots or sidewalks, while also minimizing disruption within the project area.
The general geology of the subsurface at each soil boring location was determined by examination of soil
samples collected continuously during the drilling activities. A field log noting sample composition,
sample times, and organic vapor readings was developed for each of the borings by the Geo Strata
Scientists. The shallow subsurface soils consisted predominantly of clays, which ranged from very
slightly moist to dry, and gravel/rock within a light brown silty/sandy matrix (possible fill/reworked
materials) at depths from approximately ½-foot to 14-ft. The native Navarro confining clay was
encountered at depths from 12 to 18-ft bgs.

Notes:
Completion of soil boring SB-1 was attempted at three locations. On each occurrence, the
borings were drilled through approximately 5-ft of concrete and base material and met refusal at
6-ft bgs.
Soil boring SB-5 encountered refusal at 3-ft bgs during several attempts. Per HBGCC Building
Maintenance Manager, Mr. David Kubena, the area around SB-5 was previously occupied by a
marque sign and 2-ft thick foundation, which had been alternately covered with asphalt and base
over a period of many years.
The Hunt-Zachry project manager was notified of the findings within SB-39b, and confirmed that

The Soil Boring Logs and State of Texas Well Reports are presented in Appendix C. Photographic
Documentation is presented in Appendix E.
4.4 GPS
The GPS location of each soil boring was recorded using a Trimble XH hand-held meter, capable of sub-
meter precision. The locations of the soil borings were plotted on an aerial photograph using ArcMap
GIS software. The aerial imagery (6-inch pixel color) was obtained from the City of San Antonio
geographic information system (GIS) On-line Database.
4.5 Sampling Methodology and Data Quality
4.5.1 Soil Sampling
During the drilling activities, soil samples were field screened over 2.5-foot intervals for the presence of
organic vapors utilizing a portable flame ionization detector (FID). The FID was calibrated to within 90
to 100% accuracy utilizing a calibration standard of isobutylene (100ppmv). The FID readings were
recorded on the field logs.
Field personnel utilized a new set of disposable latex gloves during the collection of each sample. The
soil samples were collected in pre-cleaned glass jars provided by DHL Laboratories (DHL). DHL
Analytical was National Environmental Laboratory Accreditation Conference (NELAC - Certificate
Number T104704211-11-7) accredited under the Texas Laboratory Accreditation Program, and utilizes a
three-tier review for quality control of analysis and data reporting. Immediately after collection, the
samples were sealed, labeled and placed on ice in an insulated cooler.
At the end of the day, the sample coolers were transported to the office, pending selection of samples for
laboratory analysis. The following morning, the Geo Strata Project Manager evaluated the completed soil
boring logs and compared the recorded FID readings. Samples exhibiting elevated FID readings were
selected first. In the event that FID measurements were non-detect (0 ppm), samples were selected from
the surfaces soil zone (typically 2 to 5-ft); within the capillary zone (if groundwater was encountered),
and at the total depth of each boring. In the event that groundwater was not encountered, a sample was
selected from the transitional zone immediately above the Navarro confining clay. A maximum of three
soil samples were selected for laboratory analysis from each boring. Proper chain-of-custody
documentation was maintained throughout sample handling and shipment.

4.5.2. Groundwater Sampling
Groundwater samples were collected from the open boring utilizing a new disposable PVC bailer at each
location. Immediately after collection, the samples were sealed, labeled and placed on ice in an insulated
cooler.
Following collection of soil and groundwater samples, each of the soil borings was properly plugged to the
surface using a bentonite and grout seal. In addition, Vortex Drilling personnel reported to the City ROW
office that all soil borings located within the ROW had been plugged, as was requested by the City ROW.
All locations were returned, as much as possible, to their original conditions.
4.6 Laboratory Analysis
The number of soil borings and suite of analyses proposed, which varied according to the type of
environmental condition, was outlined in the Phase II Summary Boring and Analytical Summary
Table prepared by Geo Strata during the project planning phase. The proposed range of analyses for soil
and groundwater included the following:
Total Petroleum Hydrocarbons (TPH) by Texas 1005
Volatile Organic Compounds (VOCs) by Method SW-846 8260
Resource Conservation and Recovery Act (RCRA) 8 Metals by EPA 6020
BTEX (collectively referred to as benzene, toluene, ethyl benzene and xylene)/ Methyl Tertiary
Butyl Ether (MTBE) by SW 8260B
Toxicity Characteristic Leaching Procedure (TCLP) by Method SW1311/6020
Groundwater samples proposed for metals analysis were submitted to the laboratory unpreserved, due to
the reactive nature of the silty groundwater and preservative (nitric acid, HNO3). In accordance with
Texas Risk Reduction Program (TRRP) guidelines, the laboratory filtered the samples with a 10
micrometer screen prior and running for total metals analysis.
Upon review of preliminary laboratory analytical results, synthetic precipitation leaching procedure
(SPLP) analysis was also requested for select samples exhibiting the maximum metals concentrations

decision-making processes that will be required during future assessment of the site to ensure regulatory
compliance.
The Phase II Summary Boring and Analytical Summary Table identifying the boring IDs and locations,
location selection rationale, and proposed laboratory analysis is presented following the Soil Boring
Location Map in Appendix A.
5.0 ANALYTICAL RESULTS
5.1 Soil Screening Levels
Soil analytical results were compared to the TCEQ, Texas Risk Reduction Program (TRRP) 0.5-acre
source area, residential protective concentration levels (rPCLs) for total soil combined (totalSoilcomb, i.e.
dermal, ingestion and inhalation exposure) to determine whether soil impacts represent a potential threat
to the construction worker.
Analytical results were also compared to the more conservative TRRP, 0.5-acre source area, residential
PCLs for soil to groundwater ingestion (GWSoilIng) and the Texas Specific Background (TxSBC) levels
(for metals only). The purpose of utilizing these more conservative values was to determine whether or
not impacts existed below construction worker protective levels, but still in excess of regulatory levels,
requiring special handling of excavated soils.
5.2 Groundwater Screening Levels
Groundwater analytical results were compared to the TRRP, 0.5-acre source area, residential PCLs for
groundwater ingestion (GWGWIng). The purpose of utilizing these values was to determine whether or not
impacts existed in excess of regulatory levels, requiring special handling of contaminated groundwater.
5.3 Discussion of Soil Analytical Results
Field Screening: Elevated FID readings (greater than 100 ppm) were not measured during field
screening. Maximum FID readings of 4 ppm were detected in surface soils (0 to 5-ft) within soil borings
SB-12B and SB-12C. Therefore, the risk of encountering organic vapors in the vicinity of the boring
locations during construction appears minimal.

In summary, the laboratory analyses of soil samples indicated:
TPH:
Metals:
Arsenic concentrations exceeded the greater of the GWSoilIng PCLs or TXSBC in the following
soil boring/soil samples (Bolded values represent the maximum detection for each metal):
• SB-4 (total depth 17.5 to 20-ft bgs): 7.88 mg/kg
• SB-10 (surface sample 2 to 5-ft bgs and total depth 17.5 to 20-ft bgs): 5.92 and 7.15 mg/kg, respectively
• SB-12a (capillary fringe 12.5 to 15-ft bgs): 13.2 mg/kg

• SB-39B (total depth 17.5 to 20-ft bgs): 6.96 mg/kg
Barium concentrations exceeded the greater of the GWSoilIng PCLs or TXSBC in soil samples
collected from SB-25 (total depth 20 to 22-ft) and SB-37 (total depth 22.5 to 25-ft bgs) at 9040
mg/kg and 5690 mg/kg, respectively. Further TCLP and SPLP analysis of the sample collected
from SB -25 indicated that the barium TCLP analytical result (2.02 mg/L) measured below the
Hazardous and Class I Regulatory Level of 100.0 mg/L, and the SPLP analytical result measured
0.0249 mg/L.
Lead concentrations exceeded the greater of the GWSoilIng PCLs or TxSBC in the following soil
boring/soil samples:
• SB-2 (surface sample 2.5 to 5-ft bgs): 18.2 mg/kg
• SB-4 (surface sample 2 to 5-ft bgs and total depth 17.5 to 20-ft bgs): 18.5 and 15.5
mg/kg, respectively
• SB-10 (surface sample 2 to 5-ft bgs and total depth 17.5 to 20-ft bgs): 15.4 and 18
mg/kg, respectively
• SB-12a (surface sample 3 to 5-ft bgs): 20.8 mg/kg
• SB-12c (surface sample 0 to 5-ft bgs): 33.9 mg/kg
• SB-12d (surface sample 2.5 to 5-ft bgs): 32.8 mg/kg
• SB-12f (surface sample 2.5 to 5-ft bgs): 22.4 mg/kg
• SB-12g (surface sample 2.5 to 5-ft bgs): 16.6 mg/kg

• SB-33 (surface 2 to 5-ft): 156 mg/kg Note: Analytical result exceeded the Class II
disposal requirements for lead (100 mg/kg).
• SB-34 (surface sample 0 to 5-ft bgs): 40 mg/kg
• SB-39A (transition zone 4 to 7.5 bgs) 144 mg/kg Note: Analytical result exceeded
the Class II disposal requirements for lead (100 mg/kg). TCLP lead analytical result
(0.0607 mg/L) measured below the Hazardous and Class I Regulatory Levels of 5.0
mg/L and 1.5 mg/L, respectively.
• SB-39B (transition zone 10 to 12.5 bgs) 26.5 mg/kg
• SB-39B (total depth 22.5 to 25-ft bgs): 21.1 mg/kg
Mercury concentrations exceeded the greater of the GW
SoilIng PCLs or TxSBC in the following
soil boring/soil samples:
Selenium concentrations appear ubiquitous within the project area and exceeded the greater of the GW
SoilIng PCLs or TxSBC in at least one sample collected from each soil boring. Maximum
detections within surface, transition, and total depth samples are provided below:
• Surface Sample: 8.25 mg/kg in soil boring SB-12f (2 to 5-ft)
• Transition Zone: 4.82 mg/kg in soil boring SB-26 (5 to 7.5-ft)
• Total Depth: 6.94 mg/kg in soil boring SB-12e (20 to 21-ft)
All other tested metals (cadmium, chromium, and silver) were non-detect or measured below
their respective PCL.
• All analyzed samples were reported as non-detect for VOCs.
Tabulated soil analytical results are presented as Tables 1 through 3, in Appendix B. The laboratory
analytical report and chain-of-custody documentation are presented in Appendix D.
Summary
Arsenic concentrations exceeding TRRP PCLs appear to be located in selected areas of Area 1 and
Area 2, and the majority of Area 3.
Barium concentrations exceeding TRRP PCLs appear to be restricted to the area located west of the
HBGCC along S. Alamo (Area 3).

Lead and Selenium concentrations exceeding TRRP PCLs appear to be located throughout Areas 1, 2,
and 3.
Mercury concentrations exceeding TRRP PCLs appear to be located throughout Area 1 and within the
northern portion of Area 3.

All analytes were non-detect with the exception of Acetone in the groundwater sample collected
from SB-33, which measured below the groundwater ingestion protective concentration level of
22 mg/L.
6.0 WASTE MANAGEMENT
Soil cuttings not reserved for field screening were placed back into the soil borings upon completion of each
boring.
Based on the findings of this assessment, Hunt-Zachry should provide notification to the property owner
indicating that metals concentrations (arsenic, barium, lead, mercury, and selenium) have been detected
above TRRP PCLs in the soils. Following notification by Hunt-Zachry, it is recommended that the
property owner notify the TCEQ regarding the results of this investigation and to discuss the next
appropriate course of action.
In addition, the following recommendations (two scenarios) are offered during Hunt-Zachry construction
and demolition activities:
Since arsenic, barium, lead, mercury, and selenium concentrations exceeded regulatory levels in the many
of the samples collected from soil borings advanced during this Phase II assessment, it is recommended

of SB-25, which exceeded health based levels and therefore, must be disposed off-site) should be either
reused on-site, or characterized, manifested and disposed off-site at an approved landfill. Laboratory
analytical result obtained during this assessment indicated the soils may be classified as Class II waste.
However, additional sampling and analysis may be required by the landfill, based upon the volume of
soils requiring disposal. Initial communications with representatives from the Republic Services landfill
indicated that it is possible the analytical data collected during this Phase II assessment, along with results
gathered during the COSA Market Street Realignment Phase II ESA (see Appendix E) could potentially
be utilized to complete the waste characterization profile. All soils impacted by metals exceeding
regulatory levels must be considered contaminated, and should not be transported off-site and treated as
clean fill material.
In addition, since soils are impacted by metals exceeding regulatory levels, it is recommended that Hunt-
Zachry consult with an environmental health and safety professional to develop a Health & Safety plan,
which will provide guidance necessary to protect the construction workers during the proposed expansion
project. At a minimum, the Health & Safety Plan should provide guidance regarding issuance and use of
personal protective equipment, and appropriate health and safety training for each of the workers that may
be potentially exposed to the metals contamination during the normal course of their work.
Note, the following information is provided for the purposes of future assessment and regulatory closure
activities: Comparison of preliminary SPLP analytical results (leachate tests) for the maximum lead and
barium concentrations observed on-site, to the TRRP groundwater ingestion PCLs, indicated that only
soils exhibiting barium concentrations exceeding 8100 mg/kg (SB-25) will require off-site disposal in
order to achieve future regulatory closure under a commercial/industrial scenario. The remaining soils
with barium concentrations below 8100 mg/kg may be reutilized on-site. SPLP results for soil samples
exhibiting maximum concentrations for arsenic, mercury, and selenium are pending.
Since sufficient groundwater analytical data was collected from the upper groundwater-bearing zone in
Areas 2 and 3 to properly assess potential groundwater impacts, groundwater encountered between
surface and 30 feet may be treated as non-impacted. An exception to this rule would be if the
construction workers observe evidence of contamination in the field, such as an unusual odor or oily
sheen on the groundwater surface. Since limited groundwater data was collected in Area 1, additional
sampling of groundwater in Area 1 will be required to determine if the water is impacted. Therefore, it is

evacuated into a storage tank on-site, sampled and characterized to determine if it has been impacted by
historic business operations, or leachate from imported fill materials.
Finally, several areas (SB-6, SB-11, and SB-28) within the HBGCC building footprint could not be
assessed, due to underground utility concerns and access limitations related to the on-going activities
within the convention center. Further assessment and sampling of these areas is recommended following
demolition of the HBGCC.

Totals
The total depth of each soil boring will be determined in the field based upon evidence of native Navarro clay. Upon encountering the native clay, the borings will be advanced a maximum of 5-ft into t he native clays and a sample will be collected from the total depth of the boring.
Potential Soil and Groundwater Analysis
If neither of the aforementioned occur, then the following samples will be collected based upon the boring depth:
A maximum of three samples from the zone between the soil s urface to 5-ft depending on sample recovery and lithology; above the water table; and at the total depth of the boring.
* = Proposed for analysis (i.e. if groundwater is encountered or in the ev ent that organic vapors are detected during field screening).
Completion of borings within the HBGCC building are not proposed for completion at this time, due potential utility and structural risks.
Bolded boring IDs were completed.
Boring could not be completed due to auger refusal.
