Integrated Water Management Planning for Industrial Facilities
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
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.
Asset Management and Reporting Strategies for Stormwater Facilities
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.
The Changing Face of Surface Water Planning and Resiliency
Climate change has threatened coastal infrastructure and drinking water supplies globally. Communities, regulators, and industry can examine and mitigate these impacts through the lens of resiliency. Coastal infrastructure planning can draw from detailed data analyses and leverage appropriate and feasible technical approaches. Drinking water source protection planning may be expanded to consider droughts, reduced snowpack, floods, wildfires, and harmful algal blooms. Presenters will describe multiple projects and processes that have been used to quantify current and future scenario risks to coastal infrastructure and drinking water utilities.
Key Issues and Tools for PFAS: Source Evaluation, Stormwater, and Ecological Risk
This presentation will provide an update on several areas of continued client and regulatory focus for per- and polyfluoroalkyl substances (PFAS) including PFAS source evaluation, presence and engineering controls for PFAS in stormwater, and ecological risk assessment. Several factors make it challenging to interpret PFAS detections including the use of PFAS in a multitude of industrial and commercial products and processes, degradation of PFAS precursors over time in the environment, and the longevity of terminal PFAS end-products. Forensic tools will be described to evaluate likely sources of PFAS in the environment, compare PFAS detections and on-site signatures to background concentrations, and develop a conceptual site model. Regarding stormwater, regulatory agencies are beginning to evaluate PFAS occurrence and transport to aquatic receptors, and develop monitoring programs for PFAS under the National Pollutant Discharge Elimination System (NPDES) framework. Tools for evaluating and assessing PFAS in stormwater and the effectiveness of passive and active stormwater controls for PFAS will be described. Finally, the latest and greatest research on PFAS aquatic toxicity and implications for ecological risk assessment will be presented. Tools and references to guide the establishment of science-based site-specific screening levels for PFAS will also be discussed.
