Emerging contaminants are the subject of fervent research and discussion within environmental compliance circles. Emerging contaminants are chemicals that are not currently (or have been only recently) regulated and for which there are concerns regarding their impact on human or ecological health.

Per-(and poly)fluoroalkyl substances (PFAS) are a family of emerging contaminants that have upended our understanding of impacted-site management. Unique challenges of PFAS are related to several factors including their complex chemistry, persistence in the environment, mobility, and toxicology.

What are perfluoroalkyl substances (PFAS) and why are they grabbing headlines? PFAS refers to a class of emerging contaminants that have challenged our understanding of water treatment. PFAS are persistent, highly mobile, and are often released as complex mixtures that may include hundreds to thousands of individual compounds. Furthermore, PFAS are ubiquitous in our society, with widespread use in products such as firefighting foams, stain- and water-resistant textiles, food packaging, and other consumer goods. Production and use of these products, coupled with widespread industrial uses for PFAS-containing materials, have resulted in groundwater and wastewater streams impacted with PFAS.

On June 22, 2020, the Toxic Substances Control Act (TSCA), as reformed by the Frank R. Lautenberg Chemical Safety for the 21st Century Act (LCSA), will celebrate its fourth anniversary. Many of the reformed TSCA framework rules have been drafted and are undergoing implementation, including recent changes to the chemical data reporting (CDR) rule. With the next CDR reporting season beginning soon (June 1, 2020), it is necessary to come up to speed on the reformed TSCA and the updated CDR reporting.

In this session, we will focus on 1,4-dioxane, which, like other emerging contaminants, is currently being evaluated by regulatory agencies for further inclusion in environmental compliance regulations. EPA included 1,4-dioxane in its December 2016 list of top 10 chemicals to be reviewed under the ongoing Toxic Substances Control Act reform.

Data collection is increasingly used to characterize natural source zone depletion (NSZD) to support LNAPL site management. While NSZD is called “MNA for smear zones” by some practitioners, the applicability of NSZD is farther reaching. Natural processes can remove hydrocarbon LNAPL bodies even when active remediation is being conducted, and it is often worth characterizing the processes early in the remedy process.

The collection of high-quality subsurface data at contaminated sites is essential to optimize site management before, during, and after remediation. Withdrawal of soil samples from unconsolidated formation can lead to drainage of pore fluids, volatilization of volatile compounds, and loss of sample from the core barrel. Cryogenic core collection is designed to preserve subsurface conditions and provide a high-resolution data set that can improve conceptual site models, facilitating remediation performance assessment and/or optimization.
