- Guidelines for Preparing SAPs: Using Systematic Planning and PBMS

Much environmental data is generated using very prescriptive requirements for sample analysis because it is assumed that this will ensure "high quality data." However, deficiencies in project planning compromise the ability of this "high quality data" to support reliable project decisions. This article, written by Barry Lesnik and Deana Crumbling of USEPA and published in the Jan/Feb 2001 issue of Environmental Testing & Analysis, discusses how a properly designed sampling and analysis plan (SAP) will address the greatest sources of decision uncertainty, which invariably stems from sampling issues. Stringent laboratory requirements cannot address this major cause of erroneous project decisions, but careful planning and increased sampling density can. Field analytical methods (used with adequate project-specific analytical QC protocols) permit cost-effective resolution of sampling uncertainty through the generation of "effective data" that provide high confidence in the reliability of project decisions.

- Clarifying the Use of SW-846 Test Methods

It has become a widespread misconception that EPA "approves" (in a restrictive sense) which methods may be used to generate data within the RCRA or Superfund programs, and that these methods must be used as written in SW-846. The reasoning then becomes that new technologies or analytical methods cannot be used unless they appear in SW-846. This is a myth! This August 7, 1998 Memorandum reiterates previous EPA guidance that "SW-846 methods need not be applied in a prescriptive manner."Additional discussion about the relationship between SW-846, the Performance Based Measurement System (PBMS) and the use of innovative analytical technologies is provided in a accompanying summary.

- Soil Sampling Quality Assurance User's Guide

Reliable environmental decisions require data of known quality, which in turn requires an adequate QA/QC program to identify and control sources of error. When investigating a relatively inhomogeneous medium such as soil, the sampling component introduces much greater error than the analytical component. This 1989 document explains vital aspects of a representative sampling and analysis design, such as the concept of "sample support," using real-world examples and detailed discussion.

DQO terms have not been used consistently over the years, and DQO terminology usage in this 1989 document is out-of-date according to current recommendations. This paper is intended to provide a basic conceptual understanding of DQO-related terms in the context of today's hazardous waste site cleanup activities. The discussion provided in this paper has been reviewed by the various DQO and data quality specialists within USEPA Headquarters to ensure that the concepts presented are consistent with EPA's original intent for DQO terminology and with the direction that program needs are currently taking.

- Superfund Representative Sampling Guidance

This December 1995 EPA Superfund guidance walks the reader through the variables that relate to the site-specific conditions, the sampling design approach, and the techniques for collection and preparation of representative samples. The importance of the conceptual site model (CSM) is discussed, and with the need for representative data collection to capture the concentration of the contaminant(s) of concern at a given time and location, reflecting the variation in pollutant presence and concentration throughout a site. Since important and potentially costly decisions are based on sampling data, it is critical that project managers and field personnel understand how accurately the sampling data characterize the actual site conditions when identifying threats, delineating sources and extent of contamination, and confirming the achievement of clean-up standards.

The Superfund guidance for representative sampling is available in 5 volumes covering soil, water, waste, air, and biological materials.

- Volatile Organic Compound (VOC) Sampling and Analysis

USEPA has updated its guidance to reflect the latest evaluation of currently available data and technologies for VOC sample handling and preservation procedures for solid samples. The procedures are designed to minimize VOC losses through the two most common mechanisms, volatilization and biodegradation. This guidance appears in SW-846 Method 5035A, which includes an accompanying 30-page appendix of detailed explanatory material.

The U.S. Army Corps of Engineers (USACE) has prepared a "Strategies" document to guide its staff to use sample collection and handling procedures that minimize VOC losses from solid samples. The USACE document supplements existing guidance provided in SW-846 Method 5035, and addresses selected aspects of sample collection, handling, preparation, and shipment. A decision tree is also provided to guide the selection of high-level and low-level sample preservation methods

Other USACE documents relevant to VOC sampling and analysis are available through the Corps' Cold Regions Research and Engineering Laboratory (CRREL), such as the Sampling and On-Site Analytical Methods for Volatiles in Soil and Groundwater: Field Guidance Manual (CRREL Report 99-16); Storage and Preservation of Soil Samples for Volatile Compound Analysis (Special Report 99-5); and Soil-Vapor Versus Discrete Soil Sample Measurements for VOCs in the Near-Surface Vadose Zone: Feasibility Study (Special Report 98-7). These reports (and other useful reports) are available for download from the USACE Reports and Products/Technical Reports website.

- An Assessment of Protocols for Splitting Soil Samples

The heterogeneous particulate nature of soil samples can cause wide variability in analytical results if the subsampling and sample splitting procedures used are not carefully selected and controlled. This study (published on-line May 14, 2002 through the Journal of Chemometrics by Gerlach et al) demonstrates the ability of riffle splitting to minimize subsampling error. In contrast, grab sampling (the most common form of subsampling) produced the worst data quality. Sample mixing prior to grab sampling may not be sufficient to avoid sampling errors when matrices are composed of particulates of different sizes and densities, as is typical of environmental soils. Sampling accuracy was at least 2 orders of magnitude worse than the analytical method accuracy of this study.

- Guidance on the Use of Passive-Vapor-Diffusion Samplers to Detect Volatile Organic Compounds in Ground-Water-Discharge Areas, and Example Applications in New England

Polyethylene-membrane passive-vapor-diffusion samplers, or PVD samplers, have been shown to be an effective and economical reconnaissance tool for detecting and identifying volatile organic compounds (VOCs) in bottom sediments of surface-water bodies in areas of ground-water discharge. Examples of applications at nine hazardous-waste sites in New England demonstrate the utility of PVD samplers in a variety of hydrologic settings, including rivers, streams, ponds, wetlands, and coastal shorelines. Results of PVD sampling at these sites have confirmed the presence and refined the extent of VOC-contaminated ground-water-discharge areas where contaminated ground water is known, and identified areas of VOC-contaminated ground-water discharge where ground-water contamination was previously unknown. The principal VOCs detected were chlorinated and petroleum hydrocarbons. Vapor concentrations in samplers range from not detected to more than 1,000,000 parts per billion by volume. These results provided insights about contaminant distributions and ground-water-flow patterns in discharge areas, and have guided the design of focused characterization activities.

- Frozen Storage of Soil Samples for VOC Analysis

The study described in this article evaluated the simplification of VOC collection and storage by freezing the sample within its storage device at -12 ±3°C. It was demonstrated that freezing the sample in its storage device immediately after collection preserves VOC concentrations in all samples matrices (including biologically active soils that would tend to degrade BTEX compounds) and for both types of VOC analytes for up to 14 days of storage. Sample integrity was maintained with less than a 5% loss of analyte concentrations even after a 14-day holding time.

This case study describes how systematic planning allowed the U.S. Army Corps of Engineers (USACE) to design and implement cost-effective cleanup of pesticide-contaminated soils at the Wenatchee Tree Fruit Research and Extension Center site. Immunoassay kits for pesticides provided real-time results that guided a dynamic work plan to seamlessly integrate site characterization and cleanup (soil removal, segregation and disposal) with surgical precision. Expensive fixed lab analyses were reserved for demonstrating that decisions based on the immunoassay data were reliable, and for generating a statistically valid data set to comply with State closure requirements. Characterization, cleanup and site closure activities were completed within a 4-month time frame. The entire project cost ($589K) was half the cost estimated under a more traditional site characterization and remediation scenario ($1.2 million). Additional details about project implementation can be found in the project's work plans and in the FRTR/USACE Cost and Performance Report.

- TCE Plume Characterized Using Field Portable GC/MS

This technology evaluation report describes deployment of the HAPSITE GC/MS by an analytical service provider to produce low-cost, real-time VOC data in the field using EPA Method 8260. The U.S. Army Corps of Engineers (USACE) used the data to make real-time decisions concerning borings placement and long-term monitoring wells installation within a single field mobilization of 3 weeks. The USACE estimated they saved $27,000 (26% of total projected costs) and 4 days of field time over project costs that would have been incurred if fixed laboratory analyses had been used. The report includes a summary of the QA/QC protocol used and project-specific analytical performance.

- Argonne National Laboratory

The Environmental Assessment Division of Argonne National Laboratory has for many years been using the same concepts and strategies captured in the Triad approach. Within DOE, these activities are often called by the name Expedited Site Characterization (ESC) or Adaptive Sampling and Analysis Programs (ASAPs). Projects managed using ASAPs or ECS have been written into several reports which can be accessed here.

- Triad Support at Five South Dakota UST Sites

In the fall of 2004, the South Dakota Petroleum Release Compensation Fund (PRCF) conducted a study to evaluate the effectiveness of the Triad approach to manage decision uncertainties at petroleum release sites with assistance from the United States Environmental Protection Agency (EPA) and Columbia Technologies. Results of the study indicated that use of the Triad reduced overall data collection and analysis costs by as much as 70% for a given site. The approach also assisted in expediting work and allowing the project team flexibility to collect data necessary for decision making in a single mobilization.
