Reductive Debromination of 1,2-dibromoethane and tribromoethylene by a Shrimp-Shell Biochar and Green Rust Composite

(Corresponding) Lindhardt J., Holm P., Lu C., Hansen H.

Topic:

Soil and groundwater contamination and remediation

Simple brominated ethanes and ethylenes like 1,2-dibromoethane (DBA) and tribromoethylene (TrBE) are widespread, toxic contaminants and able to persist in soil and groundwater. Some of these compounds are used as intermediates in the production of resins and as wood preservatives. Previous uses...Read more

Groundwater Flow Dynamics in Shallow Coastal Plain Sands Aquifer, Abesan Area, Eastern Dahomey Basin, Southwestern Nigeria.

Joseph A.

Topic:

Soil and groundwater contamination and remediation

Thirty hand-dug wells were identified and evaluated to study the groundwater flow dynamics and anionic species distribution in the study area. Topography and water table levels method with the aid of Surfer were adopted in the delineation of six recharge and discharge zones correspondingly...Read more

Biodegradation of anthracene by an Antarctic fungal strain a member of genus Alternaria

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

Topic:

Soil and groundwater contamination and remediation

By the aim to characterize the ability of an isolated from Antarctic soils fungal strain termed Alternaria maritima AL10 to degrade anthracene as sole carbon sources at different temperature conditions (23°C and 10°C), research has performed. The results from GC-MS analysis have shown that the...Read more

Preliminary assessment of groundwater Hydrogeochemistry in Kanye Area, SE Botswana

(Corresponding) Tafesse N., Mapeo R., Laletsang K., Segobaetso1 T.

Topic:

Soil and groundwater contamination and remediation

A hydrogeochemistry study was conducted in Kanye region, located in south east of Botswana, to determine the main composition controlling mechanisms in the groundwater chemistry of the area. Groundwater samples were collected and analyzed. The samples were analyzed for major cations, anions and...Read more

Groundwater recharge in Molepolole area, SE Botswana

(Corresponding) Tafesse N., Laletsang K., Mapeo R., Appia R.

Topic:

Soil and groundwater contamination and remediation

Groundwater recharge estimation using chloride mass balance (CMB) method was conducted in Molepolole area, SE of Botswana. The study area is semi-arid area with uneven distribution of rainfall throughout the year. The mean annual rainfall of the area is 423.64 mm. Climatically the area is...Read more

Modelling the Evaporation Flux from Shallow Sandy Aquifers

(Corresponding) Al-Suwaiyan M.

Topic:

Soil and groundwater contamination and remediation

A mathematical model based on Richard’s equation and the soil hydraulic properties was developed in order to understand the influence of the soil depth to the water table on the maximum potential evaporative flux through the unsaturated zone. The model was applied on shallow aquifers using...Read more

PFAS removal performance of novel technologies for treatment of firefighting water and groundwater

(Corresponding) Hjort M., Dalmijn J., Roest K., ter Laak T., Vaiopoulou E.

Topic:

Soil and groundwater contamination and remediation

Per- and polyfluoroalkyl substances (PFAS) are a group of widely used man-made organic chemical substances. PFAS have been used because of their particular physicochemical properties: most are stable at high temperatures, recalcitrant to chemical oxidation and biological degradation, and act as a...Read more

CONTAMINATED SOIL MANAGEMENT IN GREECE: EU AND INTERNATIONAL BEST AVAILABLE PRACTICES AND RECOMMENDATIONS

(Corresponding) Panagiotakis I., Strompoula E., Dermatas D., Toskos T.

Topic:

Soil and groundwater contamination and remediation

Contaminated soil management is one of the most rapidly developing environmental protection subjects. Unlike most EU countries, Greece does not have a robust Soil Strategy and as a result a Contaminated Soil Management Framework. Currently in Greece, contaminated soil management is part of the...Read more
