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
Influence of common solar and climate cycles on groundwater level variations
(Corresponding) Chapanov Y., Bournaski E.
Topic:
Estimation and prediction under past and future conditions (climate, population, land use change)
The groundwater is one of the most important natural resources. It provides drinking water and water for businesses. The level of groundwater varies in time. It has significantly seasonal oscillations and long-term variations, induced by rainfalls and climatic droughts. The seasonal, interannual...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
Investigating the impact of landfill leachates in groundwater quality through the monitoring of multiclass emerging contaminants by LC-HRMS
(Corresponding) Nika M., Gkotsis G., Vasilatos K., Gkogkou A., Stasinakis A., Thomaidis N.
Topic:
Emerging pollutants
Due to their economic advantages, landfills are the primary repository of municipal solid wastes, receiving everyday by-products such as food wastes, plastic containers and product packaging materials, unused pharmaceuticals, textile and other products. As a result of the higher demand and better...Read more
