1 INTRODUCTION
This Supplemental Field Sampling Plan (SFSP) was prepared on behalf of the City and
County of Denver (Respondent) to assess lead and arsenic concentrations in: 1) shallow
soils along a narrow tract of land within the limits of the Vasquez Boulevard/Interstate 70
(VB/I70) Superfund Site Operable Unit 2 (OU2) that was formerly owned by the Union
Pacific Railroad (UPRR); and 2) deeper soils immediately underlying the proposed lay-
back slopes of the open channel component of the Globeville Landing Outfall (GLO)
project that passes through the Globeville Landing Park.
With regards to the shallow soils, the Respondent recently acquired the UPRR property
with intentions to: a) integrate the southern portion of the parcel into the GLO project;
and b) integrate the northern portion of the parcel into the Globeville Landing Park. The
southern portion will be occupied by the open channel stormwater component of GLO
project. The northern portion will be used for recreational purposes as an extension of
the Globeville Landing Park. Accordingly, the purpose of the shallow-soil sampling
effort is to characterize lead and arsenic levels in the upper three feet of soil in the
northern portion of the property to determine if these near-surface soils may be suitable
for recreational use as is, or if some or all of the soils need to be replaced with “clean”
soil containing lead and arsenic below threshold levels. For purposes of this
investigation, threshold values consisting of 400 mg/Kg for lead (EPA Regional
Screening Level of a Residential receptor), and 70 mg/Kg for arsenic (OU-1 soil cleanup
level) are assumed to be applicable. As shown on Figure 1, the northern portion of
interest encompasses approximately 0.5 acres.
With regards to the deeper soils, the Respondent intends to assure that potential future
disturbance of soils within the upper 3 feet of lay-back slopes adjacent to the open-
channel portions of the GLO project in the Globeville Landing Park does not present a
potential future risk to worker or public health should those soils ever be disturbed.
Specifically, if lead or arsenic levels in these soils exceed the threshold values stated
above, the soils will be replaced with soils that do not exceed the threshold limits. Such
replacement will occur during GLO project construction. Note – as per the GLO design
documents, the upper 6 inches of finished-grade soil will be replaced with “clean” topsoil
that has been augmented for vegetative growth and does not exceed threshold values.
Consequently, the depth interval of interest to this investigation is between 0.5 feet and
3.0 feet below the finished grade of the lay-back slopes, as specified in the design
documents. As shown on Figure 2, the area of interest encompasses a large portion of the
Globeville Landing Park.
This SFSP presents the technical approach, methods, and procedures pertinent to
sampling shallow and deep soils. The Quality Assurance measures related to field and
laboratory activities conducted during the Design Investigation (see Quality Assurance
Project Plan (QAPP) (EMSI, 2015, Appendix C-2) apply to this investigation.

2 SAMPLING OBJECTIVES, LOCATIONS, AND DEPTHS
The objective of both shallow and deep soil sampling programs is to determine
concentrations of lead and arsenic in 1) the current uppermost three feet of soil in the
northern portion of the former UPRR property, and 2) the interval between 0.5 feet and
3.0 feet below the finished grade of the open-channel lay-back slopes within the
Globeville Landing Park, as specified in the design documents.
Shallow soil sampling locations are shown on Figure 1. They are in the northern portion
of the former UPRR property that is not scheduled to be regraded or removed by the
GLO project. Ten soil borings are proposed, generally positioned on approximately 50-
feet centers, such that results from each boring will represent approximately 2,500 square
feet of near-surface soil. Three composite samples will be collected from each boring;
one from between 0 and 1 feet below ground surface (bgs); one from between 1 and 2
feet bgs; and one from between 2 and 3 feet bgs.
Deeper soil sampling locations are shown on Figure 2, along with their sampling intervals
measured from beneath the current ground surface. Twenty-six borings are proposed,
generally positioned on approximately 100-foot centers, such that each boring will
represent approximately 10,000 square feet of soil at the target elevation. One composite
sample will be collected from each boring that will represent the 2.5-foot soil interval
sampled.

3 SAMPLING PROCEDURES AND ANALYSES
3.1 Health and Safety
Prior to performance of any field activities, all project personnel will have read,
understood, and agreed to comply with provisions of the Health and Safety Plan (HASP)
(EMSI, 2015, Appendix E) for the design investigation. Necessary safety equipment will
be readily available at the Site at all times during on-Site activities and will meet the
requirements of NIOSH/OSHA. Use, maintenance, and care of monitoring equipment
will be documented in the field logbook on a daily basis. All work will cease whenever
health and safety requirements are not followed or if environmental conditions deteriorate
to work cessation levels indicated in the HASP.
3.2 Surveying of Boring Locations and Utility Clearance
Prior to borehole drilling and sampling, the proposed boreholes will be located by a
licensed surveyor and representative of EMSI. Locations of proposed borings will be
marked with painted stakes. After locating the boreholes, the Utility Notification Center
of Colorado (UNCC) [call 811], the Denver Wastewater Management Division
https://www.denvergov.org/wastewatermanagement/WastewaterManagement/Engineerin
gandPermits/UndergroundUtility/tabid/440517/Default.aspx and the Metro Wastewater
Reclamation District
http://www.metrowastewater.com/know/PublicOutreach/Pages/utilitylocate.aspx
will be contacted to conduct a utility locates and to clear the borehole locations prior to
the start of drilling. If the location of a borehole is found to be within 10 feet of a utility
corridor, the borehole location will be moved to avoid potential impacts to the utility line.
Of particular concern is the location of the two existing large diameter sanitary sewer
lines that transverse beneath the proposed stormwater drainage structure alignment
(Figure 1).
3.3 Borehole Drilling and Sampling
Shallow boreholes will be advanced with a 3-ft long, 2-inch outside diameter Geoprobe™
core barrel equipped with a 3-ft long, 1.63-inch diameter internal plastic sampling sleeve.
As the core barrel/sampling sleeve assembly is advanced, soil core will be retained in the
sleeve. At completion of the core run, the coring assembly will be extracted and the
coring sleeve be removed from the core barrel. The sleeve will be opened and composite
samples from the three target intervals (0-1 ft, 1-2 ft, and 2-3 ft) will be collected.
Deeper boreholes will be advanced with a Geoprobe™ rig and similar sampling barrel
configuration, except the sampling barrel will be initially equipped with a drive point.
The coring assembly with drive point will advanced to the top of the sampling interval.
At that depth, the drive point will be extracted and the sampling sleeve will be inserted.
The coring assembly will then be advanced another 2.5 feet to fill the sampling sleeve.
Supplemental
Field Sampling Plan
10-11-16 Page 7
At completion of the core run, the coring assembly will be extracted, the coring sleeve
will be will be removed, and soil core from the entire run will composited into a single
sample.
At the ground surface, core samples will be logged using the ASTM Standard Practice for
Description and Identification of Soils (Visual-Manual Procedure) [ASTM D2488-06].
In addition, samples will be described using geologic interpretations and observations.
At completion of sample collection, each borehole will be abandoned by backfilling with
bentonite to the ground surface.
3.4 Sample Preparation and Analyses
Soil from each sampling interval will be composited in the field using a plastic mixing
bowl and plastic or stainless steel spatula. A sample of the composite (a minimum of 20
grams) will then be placed in a 4-ounce glass container, labeled, bubble-wrapped, and
placed in a cooler packed with ice.
A chain-of-custody (COC) record describing the contents of the cooler will be placed in a
sealed plastic bag and taped to the inside of the cooler lid. The lid will be closed,
securely taped, and sealed with a custody seal. The custody seals will be signed and
dated by the sampler.
Samples will be delivered to TestAmerica Denver where they will be analyzed for lead
and arsenic by Method SW-846 6010C. A turn-around time of 10 business days will be
requested.

Subject: Lead and Arsenic Soil Sample Results Globeville Landing Park Outfall, Phase 1B Northeast of 38th Street and Arkins Court
Denver, Colorado Project No. DN44,666.004-205
This letter was prepared by CTL | Thompson, Inc. (CTL) for Merrick & Company and presents the results of the soil sampling conducted as part of the Globeville Landing Park Outfall project in Denver, Colorado. Introduction
The purpose of our investigation was to evaluate shallow soil quality in the
tract of land in between Globeville Landing Park and the Denver Coliseum parking lot that was formerly owned by Union Pacific Railroad (UPRR). This was conducted concurrently with our geotechnical investigation and focused on the presence of Lead and Arsenic in five selected borings. We also observed for potential asbestos containing materials in the borings completed during the geotechnical investigation.
Field Investigation
CTL mobilized to the site on August 29 and 30, 2016 with Odell Drilling for
the installation of 11 soil borings. The borings were installed using a truck-mounted solid and hollow stem auger. Our Mr. Trevor Branch and Mr. Trevor Truett (Asbes-tos Building Inspector No. 17816) provided observation of test holes installed in the eastern portion of Globeville Landing Park and the southern portion of the UPRR parcel (TH-55 through TH-60) for potential asbestos containing materials. Due to data obtained from previous environmental studies, no soil sampling was conduct-ed within these borings. On August 30, 2016 soil samples were collected via dry-core sampler from the first five feet of borings TH-61 through TH-65. Soil material was collected from the top five-foot interval and placed in a stainless bowl and composited prior to being placed in laboratory provided glassware, and then into a cooler on ice. One soil sample was submitted for each of the five borings in the

northern portion of the former UPRR parcel. The samples were submitted to Origins Laboratory for analysis of Lead and Arsenic by EPA Method 3050B/6010C.
Three suspect building materials were observed and submitted to EMSL
Analytical, Inc. for analysis of bulk materials via EPA 600/R-93/116 Method using Polarized Light Microscopy. Two samples were collected from TH-55 and one sample from TH-60 were submitted for analysis for detection of asbestos fibers.
Field Screening
We used a Mini-Rae photo ionization detector (PID), and our visual and olfactory observations to field-screen soil samples obtained during drilling. The PID was calibrated to isobutylene. During field-screening, samples were placed in resealable plastic bags for testing with the PID. The bagged samples were warmed and the vapor headspace inside the bags was then field-screened. The PID de-tects total volatile organic compounds (VOCs) with the ionization potential of less than or equal to 10.6 eV. The PID does not provide a direct measure of com-pounds in the samples and it does not identify specific compounds, therefore, the results of field-screening are identified in units of parts per million volume (in air) (ppmv).
No readings were detected above 1 ppmv by the PID at any of the sampled
intervals; we believe these readings to be within background levels. We did not observe obvious visual or olfactory indicators of contamination in the soil samples or cuttings from the borings with the exception of a dark fill layer encountered intermittently in the first five feet of TH-61 through TH-65. Environmental protocol was used by CTL and its subcontractors during drilling and sampling. Gloves and plastic bags were used by CTL to obtain and screen subsurface soils. Logs of Exploratory Borings are included in Attachment A.
Laboratory Results and Discussion
Based on laboratory analytical results, concentrations of Lead and Arsenic were detected in all five samples. Tables I presents a summary of the laboratory analytical results. A complete copy of the laboratory results is presented in Attach-ment B.

The five samples exceeded the residential EPA RSL for Arsenic. Arsenic is naturally occurring in some geologic environments in Colorado due to weathering and erosion of bedrock and soil, including highly mineralized areas that are mined for metal ores. The average concentration for US EPA Region 8 Urban Mixed Use is 6-19 mg/kg and therefore we consider the concentrations of TH-62 and TH-64 to be within background levels; however, the Arsenic concentrations in TH-61, TH-63 and TH-65 exceed the background limits.
Lead exceeded the residential EPA RSL in TH-61 and TH-65 and are below
the industrial EPA RSL. The soil sample locations are shown on Figure 1 and the metals concentrations are shown on Figure 2.
The suspect building materials collected from TH-55 and TH-60 were non-
detect for asbestos. The asbestos laboratory results are included in Attachment B. Conclusions
Based on the results of field screening and limited sampling and evaluation
at the site, we believe some of the soil within the shallow fill material contains concentrations of Arsenic higher than those generally encountered in native Colo-rado soils. Lead concentrations were above the residential EPA RSL but below the industrial EPA RSL within TH-61 and TH-65. If this soil is excavated during future development activities, workers should be informed and properly protected under a Materials Management Plan or other similar type of plan.
Limitations
This letter was prepared for the use of Merrick & Company and Urban
Drainage and Flood Control in evaluating shallow soil quality. Our sampling and analytical plan was designed using previously obtained environmental background information and our judgment for the performance of a limited subsurface investi-gation based the area of proposed work. Chemical analyses were performed by Origins Laboratory in Denver, Colorado for specific parameters during this investi-gation. The accuracy and reliability of environmental studies are a reflection of the number and type of samples taken and extent of the analyses conducted by CTL. This investigation does not result in any guarantee that the site is free and clear of hazardous materials other than those that may be indicated by CTL in this report. We believe our environmental site evaluation was conducted in a manner consistent with that level of care and skill ordinarily exercised by members of the profession currently practicing in the locality of the project. No warranty, express or implied, is made by CTL.

EMSL maintains liability limited to cost of analysis . This report relates only to the samples reported and may not be reproduced, except in full, without written approval by EMSL. EMSL bears no
responsibility for sample collection activities or analytical method limitations. Interpretation and use of test results are the responsibility of the client. This report must not be used by the client to claim
product certification, approval, or endorsement by NVLAP, NIST or any agency of the federal government . Non-friable organically bound materials present a problem matrix and therefore EMSL
recommends gravimetric reduction prior to analysis. Samples received in good condition unless otherwise noted. Estimated accuracy, precision and uncertainty data available upon request. Unless
requested by the client, building materials manufactured with multiple layers (i.e. linoleum, wallboard, etc.) are reported as a single sample. Reporting limit is 1%
