Mining companies are increasingly challenged to protect water quality and avoid negative impacts to the environment and local communities. Innovative approaches to managing mine-impacted waters can help the mining sector grow and evolve. Initial mine planning, water treatment improvements, and water reclamation practices can minimize compliance issues, reduce operation and maintenance demands, and assist companies in meeting their sustainability goals. This presentation will describe several water quality challenges that mining companies face and innovative approaches and technologies to mitigate these challenges. Examples include innovative capping solutions, pit lake treatment, Gravel Bed Reactors (GBR), passive treatment systems, and more.

Water Supply Reliability: Hydrological Perspectives on Planning and Implementing Projects to Improve Reliability

Tuesday July 13, 2021, 9 am PT/12 pm ET
Speakers: Robert (Bob) Anderson, LHG, CWRE and Mark Hanna, Ph.D., P.E., LEED AP

A reliable water supply is increasingly important to meet current and future needs of municipalities, industry, agriculture, and the environment. Using basic concepts of reliability, resiliency, and a “balanced portfolio” of water supplies, presenters will address water supply reliability from the cooperative perspectives of groundwater and surface water hydrology practitioners. Groundwater is often a foundational component of water supply systems and associated watershed functions. Surface water creates the intricate architecture of our water supply, its physical infrastructure, and its connections to ecological health. Case studies will be provided of how new tools and ideas about water supply reliability can be used to solve pressing/critical issues.

New Perspectives on Remedial and Exit Strategies at Contaminated Sites

Tuesday August 10, 2021, 9 am PT/12 pm ET
Speakers: Julie Konzuk, Ph.D., P.Eng. and Rebecca Daprato, Ph.D., P.E.

Remedial strategies often evolve over time. Particularly at complex sites, remedial performance may not meet expectations and alternative technologies may be tried, with similar results. Millions of dollars and decades can be spent implementing and adjusting the remedial program. Stakeholders may lack consensus on a path to site closure. Taking a step back to re-assess conceptual site model (CSM) limitations and data gaps and identify where and why contaminants persist longer than expected can lead to insights for optimizing the remedial approach and improving performance. This presentation will describe various tools and approaches used to interrogate areas with persistent contamination, how to capitalize on and communicate the extent of natural attenuation to stakeholders, and concepts for beginning a dialogue and developing a path to closure. Case studies will illustrate potential benefits of revisiting the CSM and remedy basis, as well as the process for reaching agreement on a path to site closure, depending on the regulatory framework, stakeholder input, applicability of risk-based closure strategies, acceptable remedial timeframes, and impact on receptors.

Environment, Social, Governance Performance Versus Random Acts of Sustainability Kindness

Tuesday September 14, 2021, 9 am PT/12 pm ET
Speakers: Jill Cooper, MBA, JD and Lynn McGuire, P.E.

During this webinar, you will learn about the tools and strategies Geosyntec uses to help corporate leaders respond to and align with environment, social, and governance (ESG) and sustainability directives, aspirations, and global initiatives (e.g., the United Nations sustainable development goals (SDGs), Paris Accord, and Science-Based Targets). Presenters will describe how an analytical framework can be applied to ESG-related activities to reveal how to better contribute to financial success. Data visualization can be used with cost/feasibility and benchmarking data to better inform decision-making. Examples of tools and strategies presented will include risk management and value creation ‘balance sheets’, benchmarking data visualization, marginal abatement cost curves, and more to represent actions and ambitions, generate buy-in, and build support for sustainability actions.

Integrating Environmental Solutions with Waterfront Improvement Projects

Tuesday October 12, 2021, 9 am PT/12 pm ET
Speakers: Howard Cumberland and Christopher Robb, P.E.

Geosyntec supports large integrated waterfront redevelopment and sediment remediation projects across the United States, Canada and Australia. Our team has delivered comprehensive waterfront solutions that balance environmental remediation, geotechnical requirements, economic factors, and community needs. A conceptual site model of redevelopment objectives and potential environmental impacts to receptors (via soil, sediment, groundwater, and surface water pathways) is critical to develop, evaluate, and gain regulatory approval. Engineering design processes and specialty construction solutions have been developed and demonstrated to navigate complex subsurface and in-water environmental conditions. Examples include horizontal barrier systems, buried shoreline structures, sediment capping solutions, approaches to beneficial reuse of soil and other impacted materials, and stormwater improvements. In this presentation, we will showcase lessons learned as lead consultant or engineer of record for an urban waterway project in New York and the Waterfront Toronto project in Canada, a 1,000-acre, $1.25 billion flood protection and redevelopment effort. A third case study will feature the Crab Bank restoration project in South Carolina, which was conducted by ATM, a Geosyntec company.

A portfolio of web-based tools will also be presented – these tools allow consultants and project managers to view, validate, and analyze critical data as soon as they are available from the laboratory. Presenters will describe how these technologies have been applied to visualize data from soil, groundwater, sediment, and vapor monitoring and the direct benefits to remediation programs.

Asset Management and Reporting Strategies for Stormwater Facilities

Tuesday January 11, 2022, 9 am PT/12 pm ET
Speakers: Aaron Poresky, P.E. and Matt Bardol, P.E., CFM, CPESC, D.WRE

Stormwater facilities are a diverse class of assets, varying by facility type scale, design function, and operation and maintenance responsibility. The variability of this asset class poses unique challenges in how to assess management parameters, such as level of service, maintenance activity prioritization, and maintenance cost forecasting. Additionally, facility stakeholders (e.g., owners, local/state jurisdictions, and watershed interest and planning groups) are often required to report on the condition and performance of these assets relative to permit requirements or watershed plan goals. An effective asset management system can facilitate traditional asset management functions, support regulatory reporting and inter-agency collaboration, and serve as a foundation for stormwater system modeling. This presentation will describe how both traditional and integrated asset management frameworks can be adapted, augmented, or developed for stormwater facility assets. Examples of approaches utilized by municipal and private clients for management, reporting, and planning purposes will be discussed.

PFAS Remedy Design and Implementation in Challenging Hydrogeological Settings

Tuesday February 8, 2022, 9 am PT/12 pm ET
Speakers: Matt Vanderkooy, M.Sc., P.Geo. and Chris Shores, P.E.

Geosyntec’s site characterization and remedy design teams faced a hydrogeologically-challenging site with per- and polyfluoroalkyl substances (PFAS) contamination. The site had steeply-sloping topography and aquifers that thinned out near a major surface water body which experienced episodes of seasonal flooding. Geosyntec developed a robust conceptual site model by studying the site setting, formulating critical hydrogeological insights, and developing these through iterative field investigations. Investigation results revealed a previously unidentified major PFAS transport pathway at the Site: a set of upwelling groundwater channels. Geosyntec engineers then designed and implemented an innovative, fully passive water treatment remedy for the upwelling groundwater channels. The remedy, a set of flow-through cells, has consistently removed over 99% of target PFAS from influent water.

Advances in Dam Safety and Risk Quantification

Tuesday March 8, 2022, 9 am PT/12 pm ET
Speakers: Derek Morley, P.E. and Glenn J. Rix, Ph.D., P.E.

Many dam owners and regulators are transitioning to risk-informed dam safety programs for their portfolios. Risk assessments are a structured and systematic method of understanding potential failure modes, interactions between components of the dam system, and areas of importance and uncertainty. The webinar will describe the techniques and tools used for risk assessment and the benefits of risk-informed decision making (RIDM) for dam owners.

Science Dictates Policy through Key Regulated Chemicals on EPA’s IRIS Program

Tuesday April 12, 2022, 9 am PT/12 pm ET
Speakers: Chris Saranko, Ph.D., DABT and Travis Kline, MEM, BCES

Integrating the findings from scientific studies to form the basis for sound public policy is an ongoing challenge that has created shifting targets for some of the most prevalent environmental chemicals. This presentation will focus on three chemicals: (1) arsenic, a naturally-occurring metalloid that is present in soil at most remediation sites; (2) hexavalent chromium, a naturally-occurring metal which has been assessed by some state environmental regulatory agencies to develop toxicity values for carcinogenicity via oral exposure; and (3) polychlorinated biphenyls (PCBs), a group of man-made chemicals used extensively in wide array of industrial applications from the 1930s to the 1970s. This webinar will describe the potential changes to the toxicity values for these chemicals and opportunities for public participation in the United States Environmental Protection Agency (EPA)’s process for developing toxicity values under the Integrated Risk Information System (IRIS) program. The implications of changing toxicity values will be discussed, along with strategies and factors to consider during remediation planning and liability assessment.

An Integrated Approach to Managing Pipeline Geohazard Risks: From Identification to Permitting to Mitigation

Tuesday May 10, 2022, 9 am PT/12 pm ET
Speakers: Anica Haynes and Alex McKenzie-Johnson, P.G., L.G., L.E.G.

With changing regulatory, corporate, and societal norms, increased focus has been placed on integrity management of pipeline assets in order to reduce the impacts of pipeline operation to as low as reasonably possible. As a result, pipelines have become safer than ever before. Midstream pipeline operators can continue to improve Integrity Management Programs by efficiently identifying and managing negative impacts before they occur. Examples include geohazards such as landslides and riverine processes, potential ecological and permitting constraints, and cultural resource impacts. Combined with technical know-how for mitigation, and deep knowledge of permitting constraints that could affect the viability of mitigation options, Geosyntec has provided innovative and sound solutions to improve pipeline industry Integrity Management Programs. This presentation will provide examples of integrated approaches, demonstrating early identification of potential geohazards, complexities in the permit process, design and implementation of appropriate mitigation measures, and large-scale effective monitoring techniques that allow for early intervention.

Integrated Water Management Planning for Industrial Facilities

Tuesday June 14, 2022, 9 am PT/12 pm ET
Speakers: Philip Benson, P.E., PMP and Janet Goodfellow, P.Eng.

Water availability, quality, use, treatment, and discharge are central considerations for new and existing industrial facilities. Integrated planning considers ways to optimize social, environmental, and economic outcomes by expanding the water conversation beyond the facility’s four walls and into the affected watershed. Engineers, scientists, policy experts, and operational leaders must all be involved. This presentation will describe factors to consider and examples of inter-related decision-making regarding water supply, usage, and discharge.

Use of Geotechnical Instrumentation to Support Real Time Decision Making for Infrastructure

Tuesday July 12, 2022, 9 am PT/12 pm ET
Speakers: Chris Conkle, P.E., G.E. and Rodolfo Sancio, Ph.D., P.E., D.GE.

Geosyntec's clients have critical infrastructure that requires robust real-time monitoring during construction and operation. This work frequently occurs at remote locations and data needs to be presented to our clients as an "early warning system" in a way that allows for decision making in real time. Examples of infrastructure that requires this fully integrated instrumentation / geotechnical decision-making capability are dams, landfills pipelines, and bridges. This presentation will provide background on geotechnical instruments and their uses, as well as an illustrative example of recent project that involved the identification and mitigation of a landslide threatening four operating natural gas pipelines.
