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 ...

Contamination plumes evolve over time, and our understanding of subsurface conditions improves as data accumulates. A well that provided critical information during initial site characterization may become redundant as the plume stabilizes, while a well installed based on conservative assumptions about contaminant transport may prove to be outside the actual zone ...

Modern land development, infrastructure, and remediation projects rely on two distinct but connected streams of information: engineering-focused ground data and environmental condition data. While both come from the same physical site, they serve very different decision-making purposes. ...
Reducing Risk in the Brownfields Process If a Phase 1 ESA for a prospective Brownfields investment property indicates environmental impacts are possible or likely, Aestus offers Phase 1.5 Site Inspection scanning to image the site’s subsurface at much higher data density. This non-intrusive screening approach provides a better understanding of ...
Machine learning in oil and gas industry is used to explore data related issues. In order to Predict Operating Cash Flow Sota-X analyze Real-time operational data, Asset static data, and Variable expenses. ...
Each utility segment depicted on the final drawing is assigned a QL level from QLD to QLA under ASCE 38-02 Standard Guideline for Collection and Depiction of Existing Subsurface Utility Data. Geophysical methods employed stand at second place in the uncertainty scale as QL B, only usurped by exposing of the utility through vacuum or other means of safe ...
In fact, the ASCE 38-02 Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data is currently undergoing an update to implement a 3D standard. ...
See What You've Been Missing As consultants, we’re always looking to find the most efficient ways to understand our project site data and maximize our understanding of the conditions and processes in the subsurface. Understanding data begins with quality data management, but it's important to have a streamlined process for ...
Sand with low organic content and less specific surface area was selected to represent the ‘worst available case’ of subsurface environment in Japan. Overall, annual data (n ≥ 14) indicated that the average concentrations of THMs and HAAs for water passed through SAT with HRT less than 7 days were below the standard of drinking water. ...
The purpose of the survey was to help locate the Miraflores fault and to provide P and S wave velocity data of the sub-subsurface. The Miraflores fault is located near the Pedro Miguel Fault that runs beneath the Panama Canal west of Panama City. ...
HRSR data indicated a few topographic lows in the perched zone SDC. HRR data confirmed one known saturated topographic low and indicated two additional possibly saturated topographic lows. ...
Recently, incorporation of poultry litter by subsurface band application into pasture has been shown to reduce surface runoff transport of nutrients; however, data to evaluate the impact of this potential management strategy on forage production, forage nutrient concentrations, or the accumulation of soil nutrients after multiyear applications is limited. ...
As part of Remedial Investigation (RI) activities at the facility and surrounding areas, Black & Veatch employed the TRIAD approach to minimize investigation costs while maximizing value of data collected during subsurface soil exploration. Using historical knowledge of site activities and topography, risk assessment sampling locations were aligned with the ...
These issues have considerable practical importance in groundwater management, and in the oil industry, particularly in solving new problems posed by projects concerned with the trapping of CO2 in the subsurface. In order to manage this complexity, one must be able to prioritize the respective influences of various relevant geological and physico-chemical phenomena occurring at ...
When the effort required to find and obtain data from a previous study is comparable to collecting the data in the first place, it is just as good as having no data to begin with! ...
With time it became apparent that conventional water supply generalizations of 'homogeneity' did not adequately represent field data regarding pollution of these subsurface resources. The important role of 'heterogeneity' became increasingly clear not only in geologic terms, but also in terms of complex physical, chemical and biological ...
The seamless integration of subsurface environmental geology and analytical chemistry data with the latest tools and technology for data management and analysis make site characterization and investigation more efficient than ever before. EarthSoft’s Environmental Quality Information System—EQuIS—has been chosen by many military agencies and ...
