"1,4 Dioxane - A Review & Evaluation of Analytical Methodologies"

A widely used chemical compound, 1,4-dioxane has a multitude of industrial uses and may be present in a variety of commercial products. Historically, 1,4-dioxane had not been seen as an environmental compound of concern. When it was included on VOC target lists, many of the physical and chemical properties that make it such a useful industrial chemical also made it very difficult to determine using conventional analytical methods.

Due to the relatively recent classification of 1,4-dioxane as “likely to be carcinogenic to humans,” many regulatory standards and guidelines have been lowered. This presentation will review the three most commonly used analytical methods for low level 1,4-dioxane analysis – Method 8260 SIM, Method 8270 SIM, and Method 522. Each method will be evaluated and the data generated in a method comparison study will be presented.

The webinar will present recent experiences with the management of mature remediation sites which involve 1,4-dioxane in light of the new lower state groundwater criteria for this compound. The talk will present some analytical challenges that have resulted from field sampling and analysis of 1,4-dioxane in groundwater at varying concentrations. In addition the results of multi-laboratory QA studies conducted by Dow’s Analytical Services Department will be presented.

"Air Sample Collection and Analysis"

This discussion provides an overview of sample collection using canisters and flow controllers for both soil vapor and ambient air sampling. Various state guidance documents and requirements as related to vapor intrusion investigations are also included in this presentation. In addition, Alpha Analytical's Andy Rezendes will describe and discuss the use of digital gauges in the sampling process.

Sampling gases is different than soils and waters and represents different challenges in all phases of empirical data collection, planning, field sample collection and laboratory analysis.

With EPA and State focus on addressing ambient and indoor air quality, the risk posed by the "inhalation exposure pathway"; this focus has lead to much guidance published on Vapor Intrusion.  It is more critical than ever that data quality objectives are defined and agreed upon upfront, to meet potential scientific, legal and regulatory challenges.  This is done in the pre-program planning phase; then executing the sampling and analysis in compliance with the defined Quality Assurance plan.

This webinar addresses the question: "How do I ensure that my data is relevant and representative?"

Subjects covered include:

  • Incorporating published guidance, and defining Data Quality Objectives (DQO's) in the pre-project planning phase
  • Method selection: Review of available methods both current and emerging for Volatiles Organic Compounds: Method TO-15, TO-17, Passive Monitors Methods for Semi-Volatiles: PAH's, PCB's
  • Field Sampling: soil gas, indoor and ambient air
  • What makes my data legally defensible?

The critical importance of collecting relevant and representative data for Vapor Intrusion investigations and risk assessments cannot be overstated.  The outcomes of these investigations can include both human health risk exposure and may have significant financial implications.  Many states have or are incorporating these assessments into their guidance and regulations.  These assessments are currently incorporated into the EPA environmental programs and have also been incorporated into Brownfields programs.  This webinar will provide an overview of the analytical process for VOCs and how these processes directly relate to the data reported.  The concepts presented can be related to most analytical methods.  Additionally, the webinar discussion covers the basics of project pre-planning, sample collection, and the review of reported data.  It will provide basic information of data quality review and assessing the usability of data.

Environmental analytical laboratories play a key role in generating the information used for decision making in support of environmental assessment, remediation and numerous other project applications.  Yet typically, most laboratory clients have never been inside a laboratory and have had little exposure to how analyses are actually conducted.  This webinar will review the basic operations of the laboratory with a focus on how what takes place during the analysis of your samples ultimately affects the analytical results you receive.   The analytical procedures and instrumentation utilized to conduct several of the most common sample analyses will be discussed.

This webinar describes and discusses the potential sources for the wide variability in simultaneously extracted metal (SEM) and acid volatile sulfide (AVS) concentrations being reported by commercial and research laboratories.  Since the method is predicated on maintaining anoxic conditions required to sustain metal sulfide concentrations, exposure of sediment samples to oxygen during sample collection and analysis can result in false positive assertions of metal bioavailability.  A pilot study was conducted to evaluate the extent to which metal sulfide concentrations are affected by sample container head space and holding time.  The analysis of total metal concentrations was included to assist in the evaluation of changes in SEM concentrations given that the total metals are not predisposed to the effects of sediment oxidization.  This presentation will review and explain the pilot study as well as its findings.

In September 2009, the EPA issued warnings related to the presence of polychlorinated biphenyls (PCBs) that may be present in building materials commonly used during the construction or renovation of buildings between 1950 to 1978. This presentation and discussion will focus on the analytical considerations associated with the determination of PCBs in building materials, i.e. caulk.

Traditionally PCB sampling programs have had to choose between inexpensive, but qualitatively limiting aroclor analysis, and PCB congener analysis by high resolution GC/MS, which is highly definitive but economically challenging. 
This webinar begins with an overview of PCB chemistry and focuses on another option for PCB analysis - low resolution GC/MS which is much more comprehensive than aroclor analysis without the high cost of high resolution GC/MS.  Applications of this PCB analytical approach are discussed.

Ecological Evaluation programs, unlike conventional soil and aqueous sampling programs, pose  analytical challenges that need to be considered when scoping data collection activities. Sediment and  tissue sample media can be the most difficult sample media an environmental laboratory has to work  with yet they can also be associated with the most stringent requirements for analytical sensitivity and  data quality.  They often require additional analytical parameters and specialized methodology to meet  these requirements.  This webinar will discuss how to set up these projects for success in the  planning and scoping stages.  It will also review the analytical methods and the techniques that are  utilized to mitigate the additional laboratory challenges posed by these project applications.

The EPA has announced the long anticipated update to the 2002 OSWER Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater and Soils (Subsurface Vapor Intrusion Guidance). Many states, organizations and groups have published information, data and guidance on the Vapor Intrusion pathway investigations. After ten years, the EPA is in the final stages of updating both the guidance and their approach to evaluating the risk associated from the sub-surface vapor cloud. This presentation will focus on a laboratory’s view of Vapor Intrusion landscape and the challenges of providing data that complies with the quality requirements in order to meet the needs of these evolving regulations and programs.

Subjects the webinar will cover:

  • Status of State guidance and what we might expect from the EPA’s update
  • Screening data versus legally defensible data, current and future analytical methods
  • Best practices and some challenges to collecting relevant samples
  • What is important when collecting data?

Delivered by Will Elcoate, Alpha Analytical's National Air Sales Manager, the presentation is approximately 45 minutes in duration and will also include a question & answer session.
