Presumptive Remedies
A presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site. EPA is establishing presumptive remedies to accelerate site-specific analysis of remedies by focusing the feasibility study efforts. EPA expects that a presumptive remedy, when available, will be used for all CERCLA sites except under ...

The use of vetiver (Vetiveria zizanioides L.) for the remediation of wastewater discharged from tapioca factories
Three experiments were conducted to study the potential use of vetiver (Vetiveria zizanioides L.) to remediate wastewater discharged from a tapioca factory. Two experiments studied the tolerance of vetiver to grow in wastewater, and the other studied the factors influencing the effectiveness of vetiver for the remediation of the wastewater. Vetiver grew well in all wastewater preparations and was ...

Reviewed - Top 5 Thermal Soil Remediation Companies
Soil remediation broadly refers to the ‘repair’ and ‘renewal’ of contaminated land. To preserve the sanitation of the area, contaminants in the land are treated or removed using different soil remediation techniques. However, one of the most effective techniques that have greatly evolved over the years to restore the damaged soil is the thermal soil remediation technique. ...

Sustainable Remediation: Harnessing Bioremediation Power With Delta Remediation
What Is Sustainable Remediation? Sustainable remediation is the process of remediating polluted environments using environmentally friendly and sustainable methods. It seeks to reduce the environmental impact of cleanup processes while effectively addressing the contamination issue. Sustainable remediation also means remediation processes that end the lifecycle of the contamination rather than ...

Sustainable remediation
The term remediation refers to procedures implemented to eliminate contaminants and toxic waste from polluted landfills, water bodies and other places to promote environmental health and safety. Since its inception in the 1970s, remediation itself has evolved into a full-fledged industry. Organizations engaged in environmental construction activities typically execute remediation projects. In ...

Remediation consultancy, South Wales
Project Remediation Strategies were retained to assist a large chemical facility with the long term management of a groundwater contamination issue. Contaminants had historically entered groundwater following a spill event and despite previous remediation works by others, a residual contaminant plume remained present and was continuing to migrate off-site. Following on from previous ...

China Case Study (In Situ Gas Thermal Remediation (GTR™))
Gas Thermal Remediation (GTR™) was recently used to successfully remediate benzene and chlorobenzene impacts in China. This was the first time in situ thermal remediation was used in the history of Chinese remediation efforts. In partnership with JSDDBS, GEO used its Thermal Conductive Heating (TCH) to remove contaminants from soil and groundwater at 100 degrees Celsius. The final ...

Key Elements of a Successful Horizontal Remediation System
Environmental remediation professionals around the country (and internationally) are rapidly learning that Horizontal Remediation Systems are an essential “tool in their remediation toolbox”. When designed and executed by experienced horizontal environmental drilling experts, Horizontal Remediation Systems can be extremely effective at achieving rapid site closure compared to vertical ...

Treatability Study for Contaminated Soil Projects
What is a Treatability Study? When done correctly, a treatability study can be an important component of the remedial investigation/feasibility study (RI/FS) and the remedial design/remedial action (RD/RA) process. Engineers use this tool to help identify the full range of remedial options that are available to their client regarding safe & cost-effective remedies in the market. Remedial ...

What is Environmental Remediation?
Environmental remediation is cleaning up hazardous substances by removing, treating, and containing pollution or contaminants from environmental media like soil, groundwater, and sediment. This process is crucial for protecting the environment and public health by reducing the presence of harmful substances[1][2][3]. Remediation can involve various methods categorized as ex-situ (excavation and ...

A fuzzy multi-criteria decision analysis approach for the management of petroleum-contaminated sites
This paper presents an effective Fuzzy Multi-Criteria Decision Analysis (FMCDA) approach for contaminated site management. The development was based on: selecting eight criteria for remedial alternative evaluation and determining the weight of criteria importance under uncertainty; addressing various uncertainty issues in remedial alternative assessment process using a fuzzy-set approach based on ...

Improving Contaminated Soil Remediation
How to Improve Contaminated Soil Remediation Performance Contaminated soil remediation involves encapsulation and chemical conversion during remediation projects rendering them non-leachable to allow disposal of a non-hazardous waste. The TDJ Group has been providing heavy metal fixation technologies for more than 3 decades to the soil remediation, metal casting, and lead paint abatement ...

Groundwater remediation using simulation-optimisation approach: A review
Optimal design of a remediation system has been an active and important area of research since the past several years due to its potential to reduce the remediation cost substantially. The paper presents the state-of-the-art for application of simulation-optimisation approach to design an optimal groundwater remediation system. In the simulation-optimisation approach, the researchers have used ...

Groundwater Remediation Strategies Tool
This guide provides strategies for focusing remediation efforts on 1) the change in contaminant mass flux in different subsurface transport compartments (e.g. the vadose zone, smear zone or a zone within an aquifer of interest) and 2) the change in remediation timeframe. In this approach, groundwater flow and contaminant concentration data are combined to estimate the rate of contaminant ...

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 ...

Review of ecological‐based risk management approaches used at five Army Superfund sites
Factors used in environmental remedial decision making concerning ecological risk are not well understood or necessarily consistent. Recent Records of Decision (RODs) for Army CERCLA sites were reviewed to select case studies where remedial management occurred in response to ecological risks. Thirty‐four Army RODs were evaluated representing decisions promulgated between 1996 and 2004. Five were ...
