<p>This Engineer Manual (EM) provides guidance and background for the appropriate screening and selection of in situ thermal remediation (ISTR) technologies, including steam enhanced extraction injection, electrical resistivity heating, and thermal conductive ...

This study evaluates the formation of hydraulic barriers for secondary containment through the permeation of colloidal silica grout. A simplified infiltration model is presented to predict the downward movement of the colloidal silica grout into a soil layer, ...

Development and optimisation of fast, efficient, quantitative, economic and environmentallyfriendly analytical extraction techniques for the extraction clean up, and pre-concentration in the quantification of 16 USEPA priority polycyclic aromatic hydrocarbons ...

This paper examines the extent to which government, implementors, and users are adopting different butinterrelated mechanisms to deal with water stress in Nigeria. The paper also identifies the challenges ingovernance, government policies and priorities as ...

Samples of polluted soil contaminated with used motor oil spillage were collected to studywhether such soils may be remediated, i.e. whether the remediation of hydrocarboncontaminated soil is achievable using microbial strain sampled from the same site where ...

This article reviews literature related to the utilization of E. crassipes in the biosorption and recovery of metals from aquatic environments.

A laboratory study was conducted to investigate the ability of neutralization of red mud (RM) using carbon dioxide gas sequestration cycle at ambient conditions. The neutralized red mud (NRM) was characterized by XRD, SEM, EDX, FT-IR and auto titration method. ...

In this paper is presented a research in which samples of Romanian zeolitic (clinoptilolite) volcanic tuff and clay minerals of Lower Badenian age were tested in the ammonium removal process from wastewaters.

The technological implications of retrievability in geological disposal concepts are explored in this report. Scenarios for retrieving emplaced waste packages are considered and the report aims to identify and describe any related technological provisions ...

Geological disposal of radioactive wastes is based on the principle that the deep rock environment is stable and largely unaffected by environmental change for hundreds of thousands – even millions of years – times that are longer than those since the appearance ...
