Bioremediation of Oil-Contaminated Soil in Kazakhstan - Case Study
Project Description The project consisted of the bioremediation of soil contaminated with mineral oils and approximately 3% crude oil. The soil matrix consisted of a fine grain composition with high salt contents. Therefore, a special bioremediation process employing static regeneration had been developed. The remediation procedure also included the sensor assisted addition of air and steam ...

Svratka Site: Innovative NZVI Geochemical Barrier Supported by Direct Current (DC)
Massive contamination by chlorinated ethenes (CHCs) under an engineering plant showed to be problem for a near groundwater receiving river. The innovative approach including formation of nZVI reactive geochemical barrier was chosen by the remediation company MEGA. Moreover, a prolongation of activity of the applied NANOFER was achieved thanks to the usage of DC. Long-term monitoring and ...

Texas Mold Inspections by Texas Licensed Mold Consultant with No Conflict of Interest
Texas Mold Inspections and Mold Remediation Many Texas Mold Assessment Consultants also do mold remediation. The Texas regulations on Licensed Mold Consultants do not prevent mold inspections and mold remediation being performed by the same organization. Clearly, this is a conflict of interest. Mold Remediation is far more lucrative than mold inspections in most cases. It is clear that most ...

IEG multi level sampling well (MLSW) case study - IEG Technologie GmbH
The MLSW-system is used for the recovery of multiple high-quality samples of soil-gas and groundwater from numerous isolated horizons in a single standard borehole. The system is also used to accurately delineate contamination profiles in three dimensions, which is vital or the design, installation and monitoring of remediation systems. MLSWs also can be used for activly dispersing ...

Mechanistic sediment quality guidelines based on contaminant bioavailability: Equilibrium partitioning sediment benchmarks
Globally, estimated costs to manage (i.e., remediate and monitor) contaminated sediments are in the billions of U.S. dollars. Biologically based approaches for assessing the contaminated sediments which pose the greatest ecological risk range from toxicity testing to benthic community analysis. In addition, chemically based sediment quality guidelines (SQGs) provide a relatively inexpensive ...

Linking mechanistic toxicology to population models in forecasting recovery from chemical stress: A case study from Jackfish Bay, Ontario, Canada
Recovery of fish and wildlife populations after stressor mitigation serves as a basis for evaluating remediation success. Unfortunately, effectively monitoring population status on a routine basis can be difficult and costly. In the present study, the authors describe a framework that can be applied in conjunction with field monitoring efforts (e.g., through effects‐based monitoring programs) ...

Economic returns from monitoring and remediation of acid soils with lime application - Case Study
A long term soil acidity monitoring study was conducted in the Gabby Quoi Quoi catchment located in the central agricultural region of Western Australia, measuring change in soil pH at GIS located sample points in 1999 and 2006. Of the 300 sites sampled, 75% of the topsoil and 85% of the midsoil sampled in 1999 had pH values < 5.0, with 15% of these soils having a pH value of < 4.0. Liming ...

Detailed hydraulic assessment using a high-resolution piezocone coupled to the GeoVIS
Department of Defense (DoD) ground water assessment and remediation projects require cost effective methods for determining the direction and rate of ground water and contaminant flow. Monitoring wells have typically been used to estimate these parameters. However, detailed three-dimensional ground water and contaminant flow pathways cannot typically be delineated using monitoring well data. ...

What are some ways to monitor the impact of environmental remediation projects on wildlife and ecosystems?
To monitor the impact of environmental remediation projects on wildlife and ecosystems, several key methods can be employed:1. Environmental Surveys: Professional biologists conduct wildlife and vegetation surveys to inventory valuable species in the area. These surveys help develop mitigation measures and wildlife protection plans to safeguard rare plants and animals[1].2. Baseline Data ...
