Removal of perfluorooctanoic acid (PFOA) in groundwater by nanofiltration membrane
Perfluorooctanoic acid (PFOA) is very persistent in the environment and resistant to typical degradation processes. PFOA has been widely used in surface-active agents and as an emulsifier in several products and can contaminate groundwater. Groundwater is considered as an important source of water; hence removal of PFOA contamination in groundwater is needed. This study aimed to examine the ...

Seasonal variation in the microbial quality of shallow groundwater in the Kathmandu Valley, Nepal
To develop effective groundwater pollution control strategies for the Kathmandu Valley, Nepal, seasonal variations in microbial quality and their underlying mechanisms must be understood. However, to date, there are no studies that address these topics. In this study, groundwater samples from dug wells were collected during the dry and wet seasons from 2009 to 2012, and Escherichia coli (E. ...

Assessment of groundwater quality in the Seraidi region (north-east of Algeria) using NSF-WQI
Scarcity of water, pollution load, political issues and rising population have drawn great attention for proper management of water resources such as groundwater in the 21st century. The evaluation of groundwater quality is a critical element in the assessment of water resources. The quality/potability of water that is consumed defines the baseline of protection against many diseases and ...

Assessment of groundwater quality and health risk in drinking water basin using GIS
Eğirdir Lake basin was selected as the study area because the lake is the second largest freshwater lake in Turkey and groundwater in the basin is used as drinking water. In the present study, 29 groundwater samples were collected and analyzed for physico-chemical parameters to determine the hydrochemical characteristics, groundwater quality, and human health risk in the study area. The ...

Solid waste characterisation and the assessment of the effect of dumping site leachate on groundwater quality: a case study
In this study, the characterisation of the solid waste and the effect of the leachate from the major dumping site in Perungudi, Chennai city, on groundwater is investigated. Various physical and chemical parameters were estimated: this includes pH, total hardness, electrical conductivity, and total dissolved solids, major cations such as Ca2+, Mg2+, Na+, and K+, major anions such as NO32−, Cl−, ...

Nitrate Accumulation and Other Components of the Groundwater in Relation to Cropping System in an Aquifer in Southwestern Spain
Inappropriate farming techniques and 4 years of drought (1992–1995) produced conditions for high nitrate concentration in an aquifer located in the Province of Seville (Southwest Spain). The objectives of this study were to study groundwater components and to determine the relationship between the cropping system and nitrate concentrations in groundwater. From October 1994 to May 1996, 16 ...
