Flux measurements are valuable throughout the remediation process, aiding in risk characterization, performance monitoring, and long-term site management. They are particularly beneficial for complex or inaccessible sites, including those with mixed pollutants or under buildings, and for brownfield projects. Strategic flux monitoring can lead to cost savings of 20 to 30% on total remediation expenses.
More accurate characterization
Given the high costs of soil remediation, it's critical to execute these projects effectively to avoid wasting resources, which can make redevelopment prohibitively expensive or even unprofitable. Leveraging precise data, especially on contamination mobility, is key to accurately assessing and mitigating groundwater contamination risks, thereby ensuring remediation is both efficient and financially viable.
Design remediation plan
In situ contaminant flux measurements provide critical data to fine-tune remediation designs, identifying high flux zones and tailoring techniques to the specific pollution load.
Determine remediation urgencies and priority source zones
Flux results identify the strongest sources of contamination, quickly informing remediation priorities: identifying critical contaminations, prioritizing zones, and optimizing efforts for efficient pollutant removal.
Follow up of remediation efficiency
Monitoring the decrease in pollutant load and flux downstream from the treated area also enhances the accuracy of assessing remediation effectiveness.
Monitoring of Natural Decomposition
Measuring pollutant fluxes effectively gauges natural attenuation by comparing total pollutant loads across contamination plume sections and tracking decomposition parameters and nutrient fluxes, yielding critical insights.
Risk-based management of contamination
Removing all contamination is often unrealistic and economically unfeasible. Risk-based management considers the true risks to people and the environment, using flux sampling to accurately assess and manage these risks based on the contamination's mass and movement toward receptors.
