Screening of polar pesticides in groundwater in Hebei Province, China

Huang Y., (Corresponding) Rao Z., GUO X., YANG Z., LIU C., SHI Z.

Topic:

Soil and groundwater contamination and remediation

As a big agricultural country，China has a relatively high pesticide usage in unit area , which is three times higher than developed countries. About 80% of pesticides directly enter the soil and the water through leaching or surface runoff during the usage of pesticides. In particular, some of the...Read more

Analysis of hydrochemical time series

(Corresponding) Kolarec B., Žeravica A.

Topic:

Soil and groundwater contamination and remediation

Agricultural activity of spreading fertilizers may, in case they are washed away to an aquifer, result in a groundwater contamination. There was a research conducted in Croatia on the lower part of the Danube-Sava canal which is occupied by extensive agricultural production to measure the...Read more

Per-and polyfluoroalkyl substances (PFAS): an emerging contaminant

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

Topic:

Soil and groundwater contamination and remediation

PFAS compounds are ubiquitous in the environment and in consumer products. Unlike other emergent contaminants this is a family of compounds with, literally, thousands of compounds. Our knowledge of toxicological and environmental fate and transport properties is an evolving field. On the other hand...Read more

Groundwater quality and hydrogeochemical characterization of Khetri copper mining region, India

(Corresponding) Punia A., Siddaiah N., (Corresponding) Bharti R.

Topic:

Soil and groundwater contamination and remediation

The impact of copper mine on groundwater quality in the semi-arid region is evaluated, and also characterized for hydrogeochemical processes. Groundwater samples (post monsoon and pre monsoon) from Khetri copper mine region of Rajasthan, India were studied. In majority of groundwater samples, the...Read more

Geochemical modeling as a tool to investigate chromium contamination in groundwater

(Corresponding) Apollaro C., Fuoco I.

Topic:

Soil and groundwater contamination and remediation

The geochemical modeling is an essential tool to understand the water-rock interaction processes. In this work has been used the reaction path modelling to investigate the release and fate of geogenic Cr in ophiolitic Italian areas. During the water-rock interaction the geogenic trivalent Cr...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

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
