Through continuous monitoring of remedial progress, LiORA enabled data-driven system optimization, reducing operating costs by identifying optimal shutdown periods and enhancing system efficiency. The project demons

Executive Summary

LiORA`s comprehensive sensor monitoring system successfully enabled risk-based closure at a longstanding hydrocarbon-contaminated commercial site, demonstrating how continuous data collection can accelerate regulatory approval processes. Through the strategic deployment of soil and water sensors, LiORA provided definitive evidence of plume stability and natural source zone depletion, transforming a decades-old contamination challenge into a regulator

Executive Summary

LiORA`s comprehensive sensor network successfully demonstrated the effectiveness of natural attenuation at a large midstream crude oil and condensate facility, providing regulators with definitive evidence of plume stability and depletion. Through the deployment of 17 sensors, LiORA collected over 23 million data points in one year, quantifying an annual depletion rate of 4,490 L/year (benzene equivalents) and confirming the stability of the LNAPL pl

Executive Summary

LiORA`s monitoring system successfully guided remediation decision-making at a contaminated site in an urban area, where historical impacts had migrated onto neighboring property near residential buildings. Through integrated soil and water monitoring, LiORA provided real-time assessment of remediation effectiveness and Natural Source Zone Depletion rates, enabling data-driven decisions about transitioning from active remediation to natural attenuati

Executive Summary

LiORA`s integrated monitoring system successfully characterized the relationship between seasonal groundwater fluctuations and petroleum hydrocarbon concentrations at a former gas station site, providing critical insights for risk assessment and regulatory decision-making. By combining continuous contamination monitoring with groundwater level tracking, LiORA delivered the comprehensive data necessary to understand plume behavior and demonstrate mini

Executive Summary

LiORA`s sensor system for continuous monitoring of hydrocarbon depletion successfully supported regulatory approval for risk-based site management at a historical pipeline spill site in California. Through strategic deployment of soil sensors monitoring temperate, pressure, humidity, C02, CH4, 02, and hydrocarbon concentrations, LiORA provided real-time quantification of Natural Source Zone Depletion (NSZD) rates and plume stability data. This compre

Client Overview

Our client operates a portfolio of 350 active retail fuel sites located across multiple regions. These stations are involved in both fuel retailing and bulk transfer, and are predominantly equipped with underground fuel storage tanks (USTs). Our client is responsible for approximately 1,000 sites, which include both active and legacy sites. Over the past few years, the client has encountered rising costs associated with compliance and closure processes

Executive Summary

LiORA`s innovative technology successfully guided the remediation strategy at a former bulk fuel facility, enabling a precise Natural Source Zone Depletion (NSZD) assessment that reduced the excavation area and optimized site management. Through continuous monitoring and data-driven analysis, LiORA demonstrated how advanced sensor technology can transform traditional remediation approaches from broad-scale excavation to targeted, efficient interventi

Executive Summary

LiORA`s comprehensive sensor network successfully characterized three distinct contamination plumes at varying depths within a large industrial facility that experiences extreme seasonal groundwater fluctuations of up to 50 feet. By deploying 20 water sensors across the complex site, LiORA provided critical insights into plume behavior under dynamic hydrogeological conditions, enabling reduced monitoring requirements while maintaining comprehensive s

Executive Summary

Decades of site activities that reduced sources of hydrocarbons resulted in a complex picture of the contaminated groundwater plume. Now that immediate human and ecological health risks were addressed, the management team needed to determine if the groundwater plume was stable or if further remediation was needed to protect groundwater resources. LiORA Trends, utilizing historical sampling data, was integrated with sensor monitoring results to delive
