Presentation Description: 

This program will provide LSPs with information on several research studies related to the presence and behavior of PFAS compounds: in rainwater, at wastewater treatment plants, at sewage sludge incinerators, and in supercritical water oxidation technologies. This information will assist LSPs as they undertake the assessment and remediation of PFAS compounds in various media at MCP sites. 

Ten minutes of Q & A time will follow each of the presentations.

A Storm is Brewin’: Results of LSPA WES Grant Study of PFAS in Rain
Presented by the Project Team from Woodard & Curran, Inc. (View presenter biographies)

A recent study conducted across Massachusetts sought to assess the following questions:

  • Is PFAS present in rain falling in Massachusetts and if so, at what levels relative to other studies?
  • Is there a difference in PFAS concentration when different precipitation event types are considered?

Twenty-five distributed sampling stations were identified with a goal of testing presence or absence of PFAS and of collecting samples during both convective and stratiform rain events to assess if the type of precipitation event played a role in the presence or absence of PFAS in rain.  The presentation will discuss the geographic distribution of PFAS detected and explore the different dynamics of each storm event.

This work was conducted with the support of an LSPA WES Professional Practice Grant

Summary of Two Battelle PFAS Studies
Presented by speakers from Battelle (View biographies)

PFAS Fate and Transport at a Wastewater Treatment Plant and Collocated Sewage Sludge Incinerator, Brannon Seay, Battelle

Battelle performed a field study in 2019 to better understand the fate and transport of PFAS at a full-scale wastewater treatment plant (WWTP) and collocated sewage sludge incinerator (SSI).  Beyond this primary objective, subordinate goals included investigating the efficacy with which PFAS is potentially destroyed in the SSI under typical operating conditions; estimating emission factors for PFAS in all WWTP/SSI effluent streams; and assessing the potential impact of SSI stack emissions of PFAS on downwind ambient air concentrations. The presentation will summarize  a subset of the study results. 

Supercritical Water Oxidation  - An Innovative Approach to Destroy PFAS, Stephen Rosansky, Battelle

This presentation will describe the principles of supercritical water oxidation (SCWO) and how it is used to eliminate PFAS from aqueous impacted media.  Factors that differentiate SCWO from other PFAS treatment technologies will be discussed.  Technology limitations and impacts of site-specific factors will be presented with discussion of data collected during bench-scale and mobile demonstration tests.
