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

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

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

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

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
