    Advances in Modeling Groundwater Flow and Transport with MODFLOW (Feb 3, 2021)

    Advances in Modeling Groundwater Flow and Transport with MODFLOW (Feb 3, 2021)

    MODFLOW is a popular open-source groundwater modeling software program developed, supported, and maintained by the U.S. Geological Survey. The MODFLOW program, first released over 35 years ago, has evolved into rich suite of software programs for the simulation of groundwater flow, solute transport, and a wide range of other groundwater related processes. In 2017, the U.S. Geological Survey released a new core version of the MODFLOW program. This new version, called MODFLOW 6 (the sixth core version), extends the core MODFLOW capabilities to include robust solutions for complex water table problems, support for generalized meshes with focused resolution within areas of interest, and support for multiple models and multiple types of models within the same simulation. In addition to the Groundwater Flow Model, MODFLOW 6 now contains a Groundwater Transport Model, which can run simultaneously with the flow model or as a separate simulation using the results from a previous groundwater flow simulation. The purpose of this presentation is to describe the MODFLOW suite of programs and highlight some of the new capabilities currently available and under development for MODFLOW 6.

    Information for tribes on EPA's Interim guidance on destroying and disposing of certain per- and polyfluoroalkyl substances (PFAS) -containing materials (not consumer products) (Jan 29, 2021)

    Information for tribes on EPA's Interim guidance on destroying and disposing of certain per- and polyfluoroalkyl substances (PFAS) -containing materials (not consumer products) (Jan 29, 2021)

    Under the National Defense Authorization Act for Fiscal Year 2020 (FY20 NDAA), the interim guidance generally describes thermal treatment, landfill and underground injection technologies that may be effective in the destruction or disposal of PFAS and PFAS-containing materials.

    As required by the FY20 NDAA, the interim guidance addresses PFAS and PFAS-containing materials including:
    Aqueous film-forming foam (for firefighting); Soil and biosolids; Textiles, other than consumer goods, treated with PFAS; Spent filters, membranes, resins, granular carbon, and other waste from water treatment; Landfill leachate containing PFAS; and Solid, liquid, or gas waste streams containing PFAS from facilities manufacturing or using PFAS. The interim guidance is not intended to address destruction and disposal of PFAS-containing consumer products, such as non-stick cookware and water-resistant clothing.

    The agency is also providing guidance on testing and monitoring air, effluent, and soil for releases near potential destruction or disposal sites.

    Because EPA will accept comments on the Interim Guidance until February 22nd, 2021, we wanted to provide an overview of the guidance that might be useful to tribes in submitting comments and outline what the guidance covers and what is not included. For more information, please see www.epa.gov/pfas. To view this archive online or download the slides associated with this seminar, please visit http://www.clu-in.org/conf/tio/pfasdd_012921/

    Local Governments and Superfund Sites - Supporting Redevelopment and Addressing the Superfund Liability Concerns of Local Governments (Jan 22, 2021)

    Local Governments and Superfund Sites - Supporting Redevelopment and Addressing the Superfund Liability Concerns of Local Governments (Jan 22, 2021)

    Local governments can play a critical role in the cleanup, redevelopment, and reuse of contaminated properties. When contamination complicates property acquisition, reuse, or stewardship, local governments can help transform these properties from liabilities into community assets. However, local governments can be reluctant to play an active part in redevelopment efforts due to feeling overwhelmed on how to start or what to do. Also, concerns about potential CERCLA liability at Superfund sites may discourage local governments from this role.

    This session will share Superfund Redevelopment Program tools and best practices and highlight real-world case examples where local governments, worked with EPA to facilitate the cleanup, redevelopment, and reuse of contaminated properties in their communities. This session also will explore how Superfund liability protections and EPA's enforcement policies protect local governments during the acquisition, cleanup, redevelopment, and reuse of Superfund sites. Speakers will address EPA's newest policies directly addressing the Superfund liability concerns of local governments. This session will empower local governments by providing specific strategies and tools for local governments to successfully return these blighted properties back to productive use while minimizing their liability risk, including how to attract and form productive partnerships between local governments and developers.
