Contaminant removal from dry and wet sands by thermal desorption
Infrared heating was used to determine the effects of temperature and moisture on the removal of selected organic compounds from contaminated sand matrices. Quartz sand was used as a chemically inert surrogate for soil to isolate the heat transfer and mass transfer effects without any chemical contribution from soil. The selected organic contaminants were 3-nitrobenzene sulphonic acid, sodium ...

Metal Contaminated Soils Fixation
Treatment of Metal Contaminated Soils The EPA requires a Toxicity Characteristic Leaching Procedure (TCLP) test to determine if metal contaminated soils needs to be managed as hazardous or non-hazardous waste. Soils exhibiting hazardous characteristics need to be disposed of at a facility permitted for that material at a high cost. Soils treated in the field prior to off-site disposal can be ...

Impact–based cost–benefit analysis model for management of crude oil contaminated agricultural soil
Evaluating the compensation payable to farmers whose farms/farmlands have been rendered unproductive due to oil spill requires adequate scientific research and improved decision–making. This work proposes a bacterial–based mathematical framework as a decision–support system for evaluating crude oil spill impact on agricultural soil. The rate of 'in situ' biodegradation of the crude oil predicts ...

Kartotrak allows Dekra to justify undoubtely their conclusions
Problematics “Our work is to provide our clients with the elements of decision they need to prepare site management plans for future remediation. Before we decided to include geostatistical approach in our projects, we were used to produce contamination maps based on very simple interpolation methods and empirical calculations. We needed a rational solution which enabled us to justify ...

Local eco-systems and some sustainable development problems of Georgia
One general understanding of sustainable development concept is this being a socio-economic model of society life, satisfaction of life's necessities for the current generation should be reached without deprivation of such opportunity for next generations. Thus, rational usage of natural resources, both renewable and non-renewable ones, not causing irreversible negative influences to the ...

Lower costs, fewer delays - a highway expansion project applies XRF technology to obtain cost-effective remediation.
X-ray fluorescence (XRF) spectrometry is a non-destructive, analytical method used primarily to detect the metal composition in soil/solids samples. Portable XRF instruments can provide rapid, accurate analysis of heavy metal levels in soil on new construction or redevelopment sites. In response to the growing need for field analysis of metals, many of these units have been adapted for use in the ...

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 ...

Canadian Soil Quality Guidelines for PAHs
The document provides detailed guidelines on Canadian Soil Quality for protecting environmental and human health, focusing on Polycyclic Aromatic Hydrocarbons (PAHs). It revises the 2008 guidelines, incorporating improvements in the understanding and implementation of PAH soil quality guidelines, superseding those from 1997. The key points include:PAH Sources and Nature: PAH contamination is ...

Use of domestic sewage effluent for sustainable production of vegetable in Kashmir valley
Trace metals in discrete portions of knoll kohl were evaluated along with chemical composition of sewage effluent, irrigation water, and soil. High nutrients, Fe and Mn levels were noticed in the sewage effluent, whereas irrigation water showed recommended norms. Knoll kohl grown on sewage-irrigated soil accumulated sufficiently good amount of trace metals available to consumers. This study also ...

Deriving site‐specific soil clean‐up values for metals and metalloids: Rationale for including protection of soil microbial processes
Although it is widely recognized that microorganisms are essential for sustaining soil fertility, structure, nutrient cycling, groundwater purification and other soil functions, soil microbial toxicity data were excluded from the derivation of Ecological Soil Screening Levels (Eco‐SSL) in the United States. Among the reasons for such exclusion were claims that microbial toxicity tests were too ...

Lead Soil Contamination
What is Lead Soil Contamination? The keys to successful stabilization of lead soil contamination are: using the right reagent, using the right dosage and achieving good mixing of the reagent with the waste. Lead soil contamination involves encapsulation and chemical conversion during remediation projects rendering them non-leachable to allow disposal of a non-hazardous ...

Contaminated Soil Fixation
Contaminated soil is one that has heavy metals present within the project site. The EPA requires a Toxicity Characteristic Leaching Procedure (TCLP) test to determine if metal contaminated soil needs to be managed as hazardous or non-hazardous waste. Soils exhibiting hazardous characteristics need to be disposed of at a facility permitted for that material at a high cost. The alternative is to ...

Why is Medical Waste Management So Important?
The term “medical waste” refers to hazardous material generated from healthcare activities. It needs to be carefully managed to prevent it from posing a threat to public health and/or the environment. This means that any business, organisation, or individual involved with delivering healthcare needs to take medical waste management very seriously. To explain further, Sarah Vernau, ...

Large-scale contaminated soil investigations using Environmental Data Management Software
The Problem - Data Management Challenges Large-scale contaminated soil investigations generate hundreds, often thousands, of samples. Soil samples are collected from multiple locations, at varying depths, over many days, and by different people. Each sample is then tested for a suite of parameters and compared to regulatory guidelines to determine whether it is contaminated. This generates a ...
