Screening of 102 organic pollutants in groundwater along the Beijing-Hangzhou Grand Canal in China by GC×GC-TOFMS
(Corresponding) Rao Z., liang m., Liu L., Gong J., Zhu T.
Topic:
Emerging pollutants
Screening of 102 organic pollutants in groundwater along the Beijing-Hangzhou Grand Canal in China by GC×GC-TOFMS. A total of 45 samples were collected. The targets of the investigation involve multiple types of organic pollutants such as Polycyclic aromatic hydrocarbons (PAHs) and their...Read more
WATER SALINIZATION IN IRAN: SPATIAL VARIATION OF SALINITY IN GROUNDWATER RESOURCES OF NORTH WEST (URMIA LAKE)
Shakerkhatibi M., Jahanimoghaddam H., Esmat Saatloo M., (Corresponding) Mosaferi M.
Topic:
Water policy, management and society
This study presents the quality of drinking water in terms of salinity in the western margin of Lake Urmia, Iran. During the study a total of 121 samples from 116 wells and 5 springs were collected which constitute drinking water resources of 301 villages in the study area. Approximately more than...Read more

Fuzzy Relation Between The RDIst Index And The Water Table Of A Coastal Aquifer of Nestos Delta, Greece
(Corresponding) Papadopoulos C., Gkiougkis I., Spiliotis M., Pliakas F., Papadopoulos B.
Topic:
Floods, droughts and water scarcity
Drought is a complicated natural extreme event associated with the decline of water availability below the normal conditions of a hydrological system, both from a temporal and from a spatial point of view. This work aims to assess the drought impacts on groundwater fluctuation in a shallow coastal...Read more

A pilot test in Eastern Bohemia for chlorinated aliphatic hydrocarbons groundwater remediation
Silvestri D., (Corresponding) WACŁAWEK S., STEJSKAL V., VLKOVA D., KVAPIL P., KOHOUT P., HRABAK P., (Corresponding) ČERNÍK M.
Topic:
Soil and groundwater contamination and remediation
The bioremediation of chlorinated solvents is considered as cheap and eco-friendly approach, among the bioremediation techniques the stimulation of organohalide-respiring bacteria by adding substrates is considered as one of the most popular methods. Application of cheese whey was performed in...Read more
Mobilisation of Arsenic in groundwater, Lesvos Island, Greece
(Corresponding) ZKERI E., ALOUPI M., GAGANIS P.
Topic:
Heavy metals in the environment
In the present study, a geochemical analysis was conducted to investigate the As occurrence and release in groundwater from two different geological environments on Lesvos island: (i) the volcanic area of Mandamados (ignimbrite) and (ii) the metamorphic area of Tarti that comprises the geologic...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
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
