Confronting the Threat of SARS-CoV-2 and Future Virus Outbreaks as Environmental Contaminants
The SARS-CoV-2 virus (that causes coronavirus disease or COVID-19) has sensitized the world to the threat of outbreaks of novel viruses and viral pandemics. Consistent with Parsons’ mission to deliver innovative, technology-driven solutions to make the world safer, healthier, and more connected, strategy and actions for confronting the SARS-CoV-2 virus and future biohazard threats are presented. These include 1) safe work processes and procedures in the midst of the current crisis, 2) disinfection initiatives, and 3) prospects for enhanced virus detection, monitoring, and surveillance.
Chlorinated Ethene Plume Behavior After Source Area Bioremediation
Full-scale enhanced in-situ bioremediation was implemented at multiple tetrachloroethene (PCE) source areas at an industrial laundry facility to significantly reduce contaminant concentrations. The combination of soluble electron donor (whey) and an insoluble electron donor (EVO) successfully reduced PCE and its degradation products to below-drinking water standards (with minimal rebound) extending through the majority of the project site with significant reductions in the plume down-gradient.
Use of Mobile Form Technology and Data Analytics Dashboards for Investigation and Remediation Projects
Site investigation and remediation work is managed by Parsons using innovative mobile form technologies, Microsoft SharePoint, Microsoft SQL Server, Esri’s ArcGIS Desktop, and an online web mapping interface. The presentation results will focus on return on investment analysis on several project elements. The team is realizing considerable time and cost savings through digital data collection with immediate display and automation of reports, as well as error avoidance using constrained digital data entry that includes on-screen warnings and validation.
Influence of Mulching Operations on Long Island Groundwater – Mechanisms and Mitigation
Elevated manganese, iron, and other constituents were detected in groundwater downgradient of vegetative organic waste (including mulch) processing facilities in Long Island, New York. Parsons supported the development of mulching best management practices to mitigate effects on groundwater. The responsible mechanisms were evaluated, and a field pilot study was conducted to test mulching practices with the potential to reduce impacts to groundwater.
