National Priorities: Per-and Polyfluoroalkyl Substances. EPA is seeking applications that generate new information for nationally assessing per-and polyfluoroalkyl substance (PFAS) fate and transport, exposure, and toxicity. PFASs are manmade chemicals designed to resist heat, water, and oil. Used in a variety of consumer products and industrial applications, PFASs are moderately to highly water soluble, persistent, bio accumulative, and toxic. This RFA will inform new strategies that protect public health and the environment from PFAS exposure and adverse outcomes. The EPA anticipates funding approximately two awards under this RFA for a total of $1,984,400. The total project period requested in an application submitted for this RFA may not exceed three years. The due date for applications is June 18, 2018 at 11:59:59pm ET. For information and application instructions, see

Phytoremediation is the practice of using plants to mitigate environmental contamination and reduce exposure of humans and ecological receptors to that contamination. This webinar will introduce participants to the science of phytotechnology in the context of contaminated site remediation. Technical experts will discuss the practical aspects of phytoremediation and explore opportunities where the use of plants could be integrated as part of a remedial approach. The webinar will discuss the considerations and future of phytotechnology at contaminated sites and share additional resources. Participants will have a better understanding for evaluating phytoremediation as a remedial approach for contaminated sites. For more information and to register, see

Perspectives on the Implementation of Greener Cleanups - June 28, 2018, 2:00PM-3:30PM EDT (18:00-19:30 GMT). The practice of implementing greener cleanups to secure protective remedies with a lower environmental footprint continues to mature and expand, with greater levels of experience among regulators, site owners, and cleanup professionals alike. Through this webinar we will hear first-hand from individuals in all three sectors on their experiences with actual sites where greener cleanups have been implemented. Three of the projects applied the ASTM Standard Guide for Greener Cleanups (E2893), and represent three major federal agencies involved in site cleanups. We will also learn how greener cleanups are implemented by a corporation owning a portfolio of sites requiring remediation work. For more information and to register, see

Highlight from the CLU-IN Seminar Archives. Each edition of TechDirect highlights a previously recorded internet seminar from our archives that may be of interest to our readers. We welcome your feedback on this addition to TechDirect.

ITRC Geospatial Analysis for Optimization at Environmental Sites, Interstate Technology and Regulatory Council, Archive of Jan 30, 2018 Seminar (2 Hours, 15 Minutes). Optimization activities can improve performance, increase monitoring efficiency, and support contaminated site decisions. Project managers can use geospatial analysis for evaluation of optimization opportunities. Unlike traditional statistical analysis, geospatial methods incorporate the spatial and temporal dependence between nearby data points, which is an important feature of almost all data collected as part of an environmental investigation. The results of geospatial analyses add additional lines of evidence to decision making in optimization opportunities in environmental sites across all project life cycle stages (release detection, site characterization, remediation, monitoring and closure) in soil, groundwater or sediment remediation projects for different sizes and types of sites. The purpose of ITRC's Geospatial Analysis for Optimization at Environmental Sites (GRO-1) guidance document and this associated training is to explain, educate, and train state regulators and other practitioners in understanding and using geospatial analyses to evaluate optimization opportunities at environmental sites.

Examples of Groundwater Remediation at NPL Sites (EPA 542-R-18-002). This report highlights a select number of example National Priorities List (NPL) sites where EPA has used innovative and established technologies to restore groundwater for use as a source of drinking water. In these examples groundwater was successfully restored for drinking water use at 17 NPL sites and significant progress toward groundwater restoration was made at an additional 13 NPL sites where contaminants remain above safe drinking water levels. These sites demonstrate how the Superfund program can overcome challenges related to difficult contaminants of concern and complex hydrogeologic settings (May 2018, 114 pages). View or download at

All Hazards Waste Management Planning (WMP) Tool. EPA recommends that communities have a WMP that addresses the management of waste generated by all hazards, particularly from homeland security incidents ranging from natural disasters and animal disease outbreaks to chemical spills and nuclear incidents to terrorist attacks involving conventional, chemical, radiological, or biological agents. This tool is intended to assist emergency managers and planners in the public and private sectors in creating or updating a comprehensive plan for managing waste generated from manmade and natural disasters. The tool walks the user through the process of developing and implementing a plan. The tool also contains many resources that can be used as aids to various aspects of the planning process.
