Trifluralin-polluted soil treatment using nanosecond pulsed DBD plasma

Hatzisymeon M., Tataraki D., Rassias G., (Corresponding) Aggelopoulos C.

Topic:

Soil and groundwater contamination and remediation

Cold atmospheric plasma (CAP) was examined as an advanced oxidation process (AOP) for the remediation of trifluralin in soil. Trifluralin is a commonly used herbicide, which is toxic and persistent in soil. CAP experiments were conducted using a cylinder-to-cylindrical-grid reactor layout, driven...Read more

Column experiments to investigate the fate of per- and polyfluoroalkyl substances (PFASs) in the subsurface during soil stabilization with colloidal activated carbon

(Corresponding) Niarchos G., B. Kleja D., Ahrens L., Fagerlund F.

Topic:

Soil and groundwater contamination and remediation

Remediation of sites contaminated with per- and polyfluoroalkyl substances (PFASs) is key to reduce the contamination of drinking water sources and subsequent human exposure. PFAS production and use is increasingly being restricted worldwide, however, legacy contamination plumes in soil and...Read more

Implementation of hydroseeding methods as bioengineering techniques for soil stabilization and reclamation projects

(Corresponding) Kolkos G., Stergiadou A.

Topic:

Soil and groundwater contamination and remediation

The protection of soil from erosion is an essential element for projects where we have to deal with steep slopes terrains. Those could be construction of roads, quarry and open-pit mines. The soil stabilization occurs with the implementation of technical works such as the installation of synthetic...Read more

Phytoextraction of cadmium contaminated soils by ornamental plant: growth response, tolerance index and accumulation

(Corresponding) Gul I., Manzoor M., Zaheer M., Ahmad I., Shah G., Kallerhoff J., Arshad M.

Topic:

Soil and groundwater contamination and remediation

Cadmium (Cd) contaminated soil is a global concern and restoration of contaminated soil is challenging due to its persistence and non-biodegradability. In this study the phytoextraction capability of ornamental plant (Pelargonium zonale) for remediating Cd contaminated soil was assessed. For this...Read more

Study of the potential of Rhodococcus strains for degradation of the pesticide Glyphosate (Roundup)

Gerginova M., Peneva N., (Corresponding) Alexieva Z.

Topic:

Soil and groundwater contamination and remediation

The experiments were aimed at studying the tolerance of the studied strains of Rhodococcus sp. M1 and Rhodococcus sp. D1 to the presence of Glyphosate (N- (phosphonomethyl) glycine) in the culture medium. A rich organic medium (YEPD), a mineral medium (VD) with 1% glucose and a mineral medium...Read more

Fire-induced oxidation of Cr(III) in serpentine soils

(Corresponding) Botsou F., Vitzilaiou S., Guerra G., Valla P., Kelepertzis E., Dassenakis M., Argyraki A.

Topic:

Soil and groundwater contamination and remediation

Ophiolite rocks and their weathering products are the major hosts of Cr(III)-bearing phases in the Earth’s crust. Trivalent Cr is rather benign, but risks arise because of its potential for oxidation to the toxic and carcinogenic hexavalent form. Manganese oxides are the most effective natural...Read more

Practical Applications of Groundwater Modeling in Contaminated Site Investigation and Remediation

(Corresponding) Toskos T.

Topic:

Soil and groundwater contamination and remediation

Modeling is a very useful tool in the investigation and remediation of contaminated sites, that is generally misunderstood and underutilized. Often, modeling is perceived as requiring protracted and expensive efforts, beyond the means of most projects. However, developing a clear set of objectives...Read more

Data Visualization Techniques for Contaminated Site Investigation and Remediation

(Corresponding) Toskos T.

Topic:

Soil and groundwater contamination and remediation

Site investigations and remedial actions generate large amounts of data. While tabulating the data is necessary for the purpose of satisfying reporting requirements and comparisons to standards, it does not allow us to understand and explore relationships in the data to obtain important information...Read more

In-situ bioremediation of groundwater polluted with Cr(VI) under anaerobic conditions

Galani A., Anastopoulou P., Noutsopoulos C., (Corresponding) Mamais D.

Topic:

Soil and groundwater contamination and remediation

The natural capacity of several microbes to reduce Cr(VI) to Cr(III) has been considered of much interest in order to remediate soil and groundwater polluted with Cr(VI). The objective of this work is to evaluate the enhancement of the activity of indigenous Cr(VI) reducing bacteria by the addition...Read more

CO2-Uptake Enhances Chromate Release from Fresh Chromium Ore Processing Residues (COPR)

(Corresponding) Lapp F., Brück F., Mansfeldt T., Dohrmann R., Göske J., Weigand H.

Topic:

Soil and groundwater contamination and remediation

Chromium ore processing residue (COPR) still contains considerable chromate which can lead to groundwater contamination at uncontrolled dumpsites. The alkaline pH and presence of portlandite introduced in the high-lime roasting render COPR a potential CO2-trap. To assess whether this feeds back on...Read more
