2.1 Sampling Process Design:

Random Sampling Transect Sampling Biased/Judgmental Sampling Stratified Random Sampling Search Sampling Systematic Grid Systematic Random Sampling Definitive Sampling

Screening w/o Definitive Confirmation Screening w/ Definitive Confirmation

Sample Map Attached

The proposed sampling scheme will be judgmental, in accordance with the Guidance for Performing Site Inspections Under CERCLA, Office of Solid

Waste and Emergency Response (OSWER) Directive #9345.1-05, September 1992, and Removal Program Representative Sampling Guidance, Volume 1: Soil, OSWER Directive 9360.4-10, November 1991. Judgmental sampling is the subjective (biased) selection of sampling locations based on historical

information, visual inspection, and the best professional judgment of the sampler(s). In addition to judgmental sampling, XRF screening with definitive laboratory confirmation analysis will occur. See Appendices A and B for additional site-specific information and site maps.

Soil screening and sampling activities at residential properties and high-use areas will accord with the Superfund Lead-Contaminated Residential Sites

Handbook, OSWER 9258.7-50, August 2003. Exact sample locations will be determined during reconnaissance activities in the field. The proposed number of samples is a balance between cost and coverage, and represents a reasonable attempt to meet the study objectives while staying within the

budget constraints of a typical site investigation.

INTRODUCTION

The Tetra Tech, Inc. (Tetra Tech) Superfund Technical Assessment and Response Team (START) has

been tasked by the U.S. Environmental Protection Agency (EPA) Region 7 Superfund Division under

contract number EP-S7-13-06 to support a Removal Assessment at the Caney Residential Yards site in

Caney, Kansas. The purpose of the investigation is to determine the impact on residential soil from

previous smelting operations in Caney. This investigation will proceed under authority of the

Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) and the

Superfund Amendments and Reauthorization Act of 1986 (SARA). Removal Assessment activities will

accord with the Superfund Lead-Contaminated Residential Sites Handbook (EPA 2003).

Removal Assessment tasks will include, but not be limited to:

Collection of surface soil samples (0 to 2 inches below ground surface [bgs]) at residences to

determine lead, zinc, and cadmium concentrations.

Collection of subsurface surface soil samples (0 to 2 feet bgs) from residences and suspected

source areas to determine vertical extent of contamination.

Collection of soil samples for lead speciation.

This Quality Assurance Project Plan (QAPP) identifies site-specific features and addresses elements of

the sampling strategy and analytical methods proposed for the investigation.

SITE BACKGROUND INFORMATION

Information regarding the site’s location, description, background, and relevant investigation history is

discussed in this section.

Site Location/Description

The Caney Residential Yards site is in Caney, Kansas, in southwest Montgomery County (see Appendix

B, Figure 1). Removal Assessment activities will focus on residential properties surrounding former lead

and zinc smelting operations in Caney (see Appendix B, Figure 2). Caney covers portions of Sections 12

and 13 in Township 35 South, Range 13 East, and portions of Sections 7 and 18 in Township 35 South,

Range 14 East (U.S. Geological Survey [USGS] 1984). The city is bounded north and east by

undeveloped agricultural land, south by the Kansas-Oklahoma border, and west by the Little Caney River.

X9025.15.0099.000 2

Site Background and Previous Investigations

Two former lead and zinc smelters operated in Caney, Kansas, prior to 1931—the Owens Zinc smelter

and the American Zinc, Lead, and Smelting Company (AZLSC). Zinc and lead ores have been mined

within the Kansas, Missouri, and Oklahoma Tri-State region since the mid-1800s. The area west of the

mining district, including Caney, became a common location for smelters due to proximity of a natural

gas belt (The Governor’s Economic Development Committee 1962).

From 1904 to 1920, AZLSC operated northeast of the current Bording Avenue and North McGee Street

intersection, an area currently occupied by Caney High School. Kansas Department of Health and

Environment (KDHE) investigations at the AZLSC site included a Preliminary Assessment (1990) and a

Screening Site Inspection (1991). Investigation activities identified elevated concentrations of lead, zinc,

and cadmium at the site. A removal action was undertaken from June 1999 through April 2000 to address

contamination. The removal action resulted in creation of an on-site repository to store contaminated soil

and debris (KDHE 2015a).

From 1915 to 1931, the Owens Zinc smelter operated in northern Caney, north of Highway 166 and west

of Highway 75. KDHE investigations at the Owens Zinc site included a Preliminary Assessment (1991),

Screening Site Inspection (1992), Site Inspection Prioritization (1995), and an Expanded Site

Inspection/Preliminary Removal Site Evaluation (2001). Investigation activities identified elevated

concentrations of lead, zinc, and cadmium at the site. A potentially responsible party (PRP) was

identified, and a Corrective Action (CA) was undertaken in 2004 to address contamination. The CA

included excavating and consolidating impacted soils and waste (KDHE 2015b).

KDHE investigations at residences in Caney have identified elevated concentrations of lead, cadmium,

and zinc in surface soils at residences near the former smelters. KDHE concluded that locations of future

sampling should include residential properties between the two smelters (KDHE 2015c).

SAMPLING STRATEGY AND METHODOLOGY

In support of EPA Region 7, under this task order, Tetra Tech START will conduct soil sampling at

residences to assess impact(s) from historical smelting operations in Caney, Kansas. The Removal

Assessment will include determinations of metal concentrations and identification of lead species in

surface and subsurface soils. Sampling activities are tentatively scheduled to begin in May 2015, and will

require two to four people. Field sampling activities are anticipated to last several months. When

applicable, the standard operating procedures (SOP) and chain-of-custody (COC) procedures referenced

Page 13: QUALITY ASSURANCE PROJECT PLAN REMOVAL ASSESSMENT … · X9025.15.0099.000 2 Region 7 Superfund Program Addendum to the Generic QAPP for Superfund Lead Contaminated Sites (updated

X9025.15.0099.000 3

in this QAPP will be followed throughout the sampling activities to verify the integrity of the samples

from time of collection until submittal for laboratory analysis. Disposal of investigation-derived wastes

(IDW) and procedures for equipment and personal decontamination will be addressed in a site-specific

health and safety plan prepared by Tetra Tech. Most IDW is expected to consist of disposable sampling

supplies (gloves, paper towels, etc.) that will be disposed of off-site as uncontaminated solid waste.

Descriptions of the sampling strategy and procedures are as follows:

RESIDENTIAL PROPERTY SCREENING

To conduct soil screening activities, the Tetra Tech START field crew will attempt to obtain access at up

to 200 residential properties. START will target residences for sampling based on prevailing wind

patterns and proximity to former smelting operations to include the most likely impacted properties (see

Appendix B, Figure 2). Soil screening activities will follow guidelines established in the Superfund Lead-

Contaminated Residential Sites Handbook. Residential property screening will include collection of

surface and subsurface samples as described in the following sections.

Surface Soil/Gravel Screening

A signed access agreement from each property owner will be obtained prior to initiation of sampling

activities. After receiving access permission from the property owner, Tetra Tech START will divide the

property into distinct areas or cells for screening purposes. While the maximum size of a cell will be

100 by 100 feet, actual sizes of cells will be determined in the field based on site features. A cell will

extend from the circumference defined by the drip zone around the building or house in all directions

100 feet or to the property line, whichever distance is shorter. Additional areas or cells to be screened

include: the drip zone; fine-grained material if used for driveways, sidewalks, or under carports; road

easements; vegetable gardens; and children’s play areas at least 25 by 25 feet. A composite sample

consisting of nine aliquots, each from 0 to 2 inches bgs (to get below the root zone), will be collected in

each cell by use of a disposable stainless steel spoon or hand trowel, and placed in a labeled, sealed

plastic bag. This procedure differs from EPA Region 7 SOP 4230.19, which specifies collection of

samples from the top 1 inch of soil.

All soil and gravel samples will be transported back to a sample preparation facility with their

corresponding screening forms. At the sample preparation facility, each sample will be transferred to a

clean, dedicated paper tray. Because moisture content of a soil or gravel sample can adversely affect

accuracy of x-ray fluorescence (XRF) spectrometer readings for lead, the samples will be allowed to

completely air dry or will be placed in ovens to heat and dry the samples. If used, ovens will not be

Page 14: QUALITY ASSURANCE PROJECT PLAN REMOVAL ASSESSMENT … · X9025.15.0099.000 2 Region 7 Superfund Program Addendum to the Generic QAPP for Superfund Lead Contaminated Sites (updated

X9025.15.0099.000 4

operated above a temperature of 350 degrees Fahrenheit (°F). Because the melting point of lead is

approximately 620 °F, the drying process should not alter lead concentrations in the samples. Once dried,

samples will be homogenized, passed through a number 10 sieve (2-millimeter), and then screened for

lead by use of an XRF spectrometer. XRF screening of soils will accord with EPA Method 6200. Three

separate XRF readings will be taken from each sample, and then the average of the three readings will be

calculated and recorded on the screening form.

To determine XRF screening precision and accuracy, a subset of screened soil samples will be sent to the

EPA Region 7 laboratory for confirmation analysis. In general, screened samples will be selected at a

10 percent (%) frequency for laboratory confirmation analysis. During the initial phase of the

investigation, samples may be submitted at a higher frequency. Sample analytes will include total lead,

cadmium, and zinc. Laboratory data and XRF screening results for lead will be compared to determine a

site-specific data correlation. For this project, a regression coefficient (r2) of at least 0.7 is required for

the XRF results to be considered reliable for decision making regarding removal.

Subsurface Soil Screening

Tetra Tech START will attempt to define the vertical extent of contamination through collection of

subsurface soil samples within 0 to 2 feet bgs at a subset of properties. Subsurface soil samples will be

collected within approximately 10% of sampled cells. Initial subsurface sampling will occur at residential

properties sampled by KDHE during previous investigations. Surface contamination is well defined at

these properties; therefore, subsurface sampling will target areas of highest metal concentrations to

determine the vertical extent of contamination. Subsequent subsurface sampling will be conducted at

residences sampled by START during the Removal Assessment. EPA and START will use professional

judgement to select properties for subsurface sampling. START will contact Kansas One-Call to ensure

that all underground utility lines within the areas of interest are marked prior to initiation of subsurface

sampling activities.

Subsurface sampling will proceed by use of a manual soil boring device (i.e., slide hammer or slam bar).

At all subsurface sampling locations, samples will be collected at 6-inch depth intervals (i.e., 0-6 inches,

6-12 inches, 12-18 inches, 18-24 inches bgs). Each subsurface sample will undergo the same processing

procedures, field screening, and laboratory analyses applied to surface soil samples (see above section).

Field-screened subsurface samples will be submitted for laboratory confirmation analysis at frequency of

10%. XRF and analytical data from subsurface sampling will be used to determine the vertical extent of

Page 15: QUALITY ASSURANCE PROJECT PLAN REMOVAL ASSESSMENT … · X9025.15.0099.000 2 Region 7 Superfund Program Addendum to the Generic QAPP for Superfund Lead Contaminated Sites (updated

X9025.15.0099.000 5

contamination at the site, including identification of subsurface contamination within areas where no

contamination had been identified in surface soils.

SAMPLING FOR LEAD SPECIATION

To identify forms and potential origins of lead at the site, START will collect samples for lead speciation

analysis. Six samples will be collected to undergo lead speciation analysis: one from the Owens Zinc

site, one from the AZLSC site, one from a background location, and three from residences. Composite

surface soil samples (0 to 1 inch bgs) consisting of nine aliquots each will be collected and processed

following the same procedures outlined in the residential soil screening section. After completion of

processing, samples will be submitted to the Laboratory of Environmental and Geological Studies

(LEGS) at the University of Colorado in Boulder, Colorado. Results from lead speciation analyses will

be used to determine influence of previous smelting operations on lead in soils at the site.

QUALITY CONTROL SAMPLES

Quality control (QC) samples for the site will consist of field duplicates collected at a 10% frequency.

ANALYTICAL METHODS

Soil sample analysis will accord with SOPs and methods referenced in Tables 1 and 2. Soil samples for

analyses for lead, cadmium, and zinc will be submitted to the EPA Region 7 laboratory in Kansas City,

Kansas. Soil samples selected for lead speciation analysis will be submitted to LEGS at the University of

Colorado in Boulder, Colorado. Standard turnaround times and detection limits for those methods will be

adequate for this project. Appropriate containers and physical/chemical preservation techniques will be
