Preliminary Surface Soil Sampling Report

River Terrace Municipal Park

Channelview, Texas

Langan Project No.: 510028401

Dear Dr. Babin:

Langan Engineering and Environmental Services, Inc. (Langan) has prepared this Preliminary

Surface Soil Sampling Report on behalf of the Harris County Pollution Control Services (HCPCS)

for the River Terrace Municipal Park located at 16550 Market Street, Channelview, Texas (the

“site”). A Sampling Location Map is provided as Figure 1.

This report documents the preliminary soil sampling activities at three locations throughout the

park and one off-site background location to sample for the potential presence of dioxins and

furans.

BACKGROUND

Langan understands that construction upgrades are proposed at the River Terrace Municipal

Park. The 13.9-acre park is located adjacent to the San Jacinto River, downstream of the San

Jacinto River Pits Superfund Site. HCPCS requested preliminary surface soil sampling to assess

the potential presence of dioxins and furans at the park.

SAMPLING AND ANALYSIS

On July 25, 2017, Langan collected three composite surface soil samples throughout the River

Terrace Park. Three areas within the River Terrace Park were chosen by the HCPCS for

sampling (Areas A, B, and C). Within each area, three samples were collected for an area

composite surface soil sample. The HCPCS also selected the location for a “background”

surface soil sample. The background composite sample was collected at the Rio Villa Nature

Trail.

A Surface Soil Sampling Standard Operation Procedures (SOP) was prepared by Langan prior to

the field activities. The SOP was reviewed and approved by the HCPCS on July 21, 2017.

The SOP included the following sampling and analysis procedures:

Upon arrival at the sites, a field data sheet was completed at each location. Information

recorded included sample identification, time on-site, weather conditions, and the level

of personal protective equipment (PPE). Langan personnel also collected GPS

coordinates of the sample locations. Copies of the Field Data Sheets are provided in

Attachment A.

The soil samples were collected with a stainless steel hand auger. The top layer of

grass and vegetation were removed and samples were advanced to approximately 6-

inches below grade. This was repeated at three locations within each of the sampling

areas.

Soil samples from each area were combined into clean, re-sealable plastic bags and

mixed to create a composite surface soil sample. Each composite sample was

transferred into pre-cleaned jars that were provided directly from the laboratory.

Each sample collected was assigned a unique identification name, denoting where it

was collected. The River Terrace Park samples were identified as “RTP-X”, where X

indicates the area within the park that the sample was composited from. The

background sample was identified as “RioVilla-1”. Each sample container had a sample

label affixed to the outside with the project name, date, and time of sample collection.

During sampling activities, a blind duplicate sample (DUP) was collected at sample

location RTP-C. In order to keep the duplicate sample separate from the parent sample,

no collection time was listed on either the sample label or the COC.

As requested by HCPCS, a background sample was collected from the Rio Villa Nature

Trail, approximately 3.7 miles northeast of the site. Soil sampling procedures at this

location were similar to those conducted at the River Terrace Park listed above.

The hand auger was cleaned between each sampling location by scrubbing with

Alcanox and water until residual soil was removed from the auger, followed by two

rinses with deionized and distilled water. Given the low potential for significant impacts,

the waste waters in the buckets were emptied back onsite after sampling was

completed.

Immediately after collection, the samples were labeled and placed on ice in an insulated

cooler provided by the laboratory. After sampling, the cooler was secured and shipped

overnight via Fed-Ex under a laboratory provided chain-of-custody (COC) form to

Eurofins Lancaster Laboratories Environmental, LLC, a state of Texas certified

laboratory, located at 2425 New Holland Pike in Lancaster, Pennsylvania. Langan

included a completed COC in each cooler that was shipped to the laboratory. All

samples were reported by the laboratory to have been received intact and within the

appropriate temperature range.

LABORATORY ANALYTICAL RESULTS

Soil sampling results are summarized on Table 1. The laboratory analytical report was prepared

by Eurofins and included a signed statement certifying that the laboratory was NELAP (National

Environmental Laboratory Accreditation Program) accredited under the Texas Laboratory

Accreditation Program for all methods, analytes, and matrices reported in the data package. A

copy of the laboratory analytical report and chain-of-custody forms are provided in Attachment

B.

The soil samples were analyzed for the 17 dioxin and furan congeners identified by HCPCS. To

determine toxic equivalencies (TEQs) of the soil samples, a toxic equivalency factor (TEF) was

applied to each congener. TEFs were applied as outlined in the December 2010 U.S.

Environmental Protection Agency (EPA) Guidance Document “Recommended Toxicity

Equivalence Factors (TEFs) for Human Health Rick Assessments of 2,3,7,8-Tetrachlorodibenzo-

p-dioxin and Dioxin-like Compounds”. As reproduced in Table 1, TEFs listed in this document

ranged from 0.0003 to 1, with most of the equivalency factors being less than one. The TEFs

were multiplied by the detected concentration of the congener within each sample. In the case

where a congener was not detected above the laboratory detection limit (DL), half the DL was

used in calculating the TEQ.

As this sampling was conducted for preliminary assessment purposes, a data validation and

usability report was not completed for this project. Therefore, for congeners where the data

was qualified with a Q values by the laboratory, Langan used the reported value in the TEQ

calculation. However, when the laboratory was calculating the TEQs, congeners where Q

values were reported were treated as non-detects, and half the DL was used in calculating the

TEQ. As such, TEQ values calculated below differ slightly than those calculated and reported by

the laboratory.

Based on guidance provided by HCPCS, the 2,3,7,8-TCDD TEQs were compared to the USEPA

2,3,7,8-TCDD Residential Soil Regional Screening Level (RSL) based on current USEPA Non-

Cancer (nc) risk endpoint. The TEQs for soil samples collected ranged from 4.037 ng/kg to

17.614 ng/kg, which are below the USEPA Residential Soil (nc) RSL of 51 ng/kg for 2,3,7,8-

TCDD.

Additionally, a background sample was collected at the Rio Villa Nature Trail to compare soil

samples in the project areas to background concentrations of dioxins and furans soil outside the

project area. The TEQ of the background sample RioVilla-1 was 3.899 ng/kg thus below the US

EPA Residential Soil (NC) RSL

CONCLUSIONS

The following is a summary of the major findings of this investigation:

The surface soil composite sample 2,3,7,8-TCDD TEQs ranged from 4.037 ng/kg to

17.614 ng/kg, which are below USEPA Residential Soil (nc) RSL of 51 ng/kg.

The TEQ for the background surface soil composite sample was 3.899 ng/kg, also

below the USEPA Residential Soil RSL.

Thank you again for selecting Langan to assist you on this project.

Sincerely,

Langan Engineering and Environmental Services, Inc.

Explanation of Symbols and Abbreviations

3768 0717

The following defines common symbols and abbreviations used in reporting technical data:

BMQL Below Minimum Quantitation Level C degrees Celsius cfu colony forming units CP Units cobalt-chloroplatinate units F degrees Fahrenheit g gram(s) IU International Units kg kilogram(s) L liter(s) lb. pound(s) m3 cubic meter(s) meq milliequivalents

mg milligram(s) mL milliliter(s) MPN Most Probable Number N.D. non-detect ng nanogram(s) NTU nephelometric turbidity units pg/L picogram/liter RL Reporting Limit TNTC Too Numerous To Count µg microgram(s) µL microliter(s) umhos/cm micromhos/cm

< less than > greater than ppm parts per million - One ppm is equivalent to one milligram per kilogram (mg/kg) or one gram per million grams. For

aqueous liquids, ppm is usually taken to be equivalent to milligrams per liter (mg/l), because one liter of water has a weight very close to a kilogram. For gases or vapors, one ppm is equivalent to one microliter per liter of gas.

ppb parts per billion Dry weight Results printed under this heading have been adjusted for moisture content. This increases the analyte weight basis concentration to approximate the value present in a similar sample without moisture. All other results are reported on an

as-received basis. Analytical test results meet all requirements of the associated regulatory program (i.e., NELAC (TNI), DoD, and ISO 17025) unless otherwise noted under the individual analysis.

Measurement uncertainty values, as applicable, are available upon request.

Tests results relate only to the sample tested. Clients should be aware that a critical step in a chemical or microbiological analysis is the collection of the sample. Unless the sample analyzed is truly representative of the bulk of material involved, the test results will be meaningless. If you have questions regarding the proper techniques of collecting samples, please contact us. We cannot be held responsible for sample integrity, however, unless sampling has been performed by a member of our staff.

This report shall not be reproduced except in full, without the written approval of the laboratory.

Times are local to the area of activity. Parameters listed in the 40 CFR Part 136 Table II as “analyze immediately” are not performed within 15 minutes.

Data Qualifiers

Qualifier DefinitionC Result confirmed by reanalysis

D1 Indicates for dual column analyses that the result is reported from column 1

D2 Indicates for dual column analyses that the result is reported from column 2

E Concentration exceeds the calibration range

J (or G, I, X) Estimated value >= the Method Detection Limit (MDL or DL) and < the Limit of Quantitation (LOQ or RL)

P Concentration difference between the primary and confirmation column >40%. The lower result is reported.

U Analyte was not detected at the value indicated

V Concentration difference between the primary and confirmation column >100%. The reporting limit is raised

due to this disparity and evident interference.

W The dissolved oxygen uptake for the unseeded blank is greater than 0.20 mg/L.

Z Laboratory Defined - see analysis report

Additional Organic and Inorganic CLP qualifiers may be used with Form 1 reports as defined by the CLP methods.

Qualifiers specific to Dioxin/Furans and PCB Congeners are detailed on the individual Analysis Report.
