Dive into soil and groundwater remediation for former heavy equipment manufacturing site in New York impacted with chlorinated volatile organic compounds. The remediation process involved an innovative new method of auger soil mixing developed by Geo-Solutions, Inc. that significantly reduced the volume of water needed relative to the traditional auger mixing method. The technique was used to reduce the risk of construction-related discharge to adjacent wetlands and hydrologic features of regulatory interest. This new method not only reduced concerns relative to potential fluid discharges, but also incorporated sustainable use of water resources and landfill space and left the site in better condition for post-remedial management.

A big need in the environmental space is finding a way to capture environmental data to ensure regulatory compliance. For many sites, a vast and rich dataset exists in text form, and mining this text presents the opportunity to build or enhance our knowledge about a site. Discover how custom AI models, tools and capabilities can turn text from documents into data assets, providing unprecedented access to information and improving the performance of predictive models.

Natural source zone depletion (NSZD) has evolved as a viable solution for the remediation of sites contaminated with non-aqueous phase liquid (NAPL) and refers to the restoration NAPL source zones through a combination of physical, chemical, and biological processes. We will compare NSZD rates at multiple sites contaminated with NAPL quantitatively. Comparison of NSZD rates under various field conditions in terms of geological, hydrogeological, and contaminant compositional parameters will provide insight into biogeochemical processes and how these can be enhanced in a complementary fashion to achieve complete remediation and site closure.

Learn about the role that remediation practitioners can play in supporting their client’s decarbonization journeys. Many organizations around the world have set decarbonization targets and are looking for ways to reduce greenhouse gas emissions from a variety of sources. Hear about lessons learned from a case study of a decarbonization project involving construction work, fleet management, and remediation activities. This case study will be used to illustrate challenges and opportunities associated with the implementation of sustainable remediation practices and tools, and how they can provide co-benefits and solutions for other environmental impacts.

Recent years have brought a new understanding of the importance of sustainable remediation and nature-based management strategies at petroleum NAPL sites. Using a site with a pipeline release as our focus, we will examine the use of LNAPL transmissivity and NSZD in the decision-making process to transition to enhanced NSZD (eNSZD) and in the planning process for the future transition away from eNSZD to NSZD. This presentation will include a review of the effectiveness of the low-temperature heating eNSZD.

Metals can be precipitated out of groundwater by altering geochemical conditions to make the metals less soluble or by causing the metals to undergo a chemical reaction that results in an insoluble product. Groundwater chemistry can be complex however, and laboratory and pilot testing can enable us to tailor treatment to the chemistry at the site. Learn about laboratory and pilot testing performed to design treatment for the removal of hexavalent chromium and nickel from groundwater at a former automobile industry site in Michigan. We will explore the use of sulfur-containing reducing agents, such as sodium dithionite and sodium sulfide, to remove these metals such that the removal was unlikely to be reversed.

In the face of modern problems such as climate change, energy shortages and air pollution, excessive remediation can be a contributor rather than a solution. In order to successfully gauge the true value of a remediation program, additional considerations beyond those typically included in site evaluations should be considered; for example, carbon footprint, resource consumption, risk to human health, and historic efficacy of remediation on plume reduction. In this presentation we review the value of select mature real world remediation programs with these considerations, and propose that our communities and industry would benefit from the standardization of these considerations, especially with respect to mature site evaluations.
