In this study, movement of phosphorus pollution which is leachate to groundwater was investigated in Seri Petalling Landfill. Visual MODFLOW was used to predict subsurface and surface migration of pollution within 10 years. The results of sample analysing of phosphorus has shown its concentration in place of landflill was 2.38 mg/l since the National Water Quality Standard for Malaysia defined ...

At the “Pašino vrelo” source, groundwater is exploited by means of wells which tap a carbonate aquifer of Badenian age. The natural quality of groundwater complies with the provisions of the Regulation on health and safety of drinking water. However, anthropogenic impacts in the form of microbiological pollution have been observed. Extensive hydrogeological investigations have been conducted in...

There is rapidly growing interest in the use of market-based (MB) instruments in environmental policy. The papers in this session discuss three relatively new areas for such policies: groundwater contamination, nonpoint source surface-water pollution and carbon sequestration. The papers point out the potential for MB policies in these areas, but significant challenges remain. This comment highl...

This paper deals with the analysis of different realizations regarding groundwater pollution. The groundwater behaviour can be implemented using a mixture of diffusion and convection equations. The analysis of the convection diffusion equation is also interesting for other research areas, for example biology, chemistry and the stock market. The first part will deal with the derivation of the re...

Human activity greatly influences nitrogen (N) pollution in urbanized and adjacent areas. We comprehensively studied the N cycling in an urban–rural complex system, the Greater Hangzhou Area (GHA) in southeastern China. Our results indicated that subsurface N accumulation doubled, riverine N export tripled and atmospheric N pollutants increased 2.5 times within the GHA from 1980–2004. Agricultu...

Q.5-How do I assess the risk of groundwater quality problems arising from pollution of urban aquifers? Written specifically for this Web-site by Brian Morris and Stephen Foster, drawing extensively from Foster and Hirata 1988, Morris and Foster 2000 (see references) and unpublished material.

Trichloroethylene (TCE) is a common industrial solvent that poses a particular pollution problem in groundwater; while TCE disappears from surface water within a few weeks, groundwater contamination can take months or years to degrade. Humans have not conclusively been shown to develop cancer in response to TCE exposure, but rats and mice exposed to TCE have an increased incidence of liver and ...

during recent years there has been increasing consciousness of, and concern about, groundwater water pollution and monitoring in iran. in this context, a comprehensive review of the trace elements and heavy metals in groundwater of oshtorinan plain in northern part of boroujerd has carried out to investigate the effects of weathering minerals, agricultural and industrial activities. groundwater...

In the Pingtung Plain of southern Taiwan, elevated levels of NO₃--N in groundwater have been reported. Therefore, efforts for assessing groundwater vulnerability are required as part of the critical steps to prevent and control groundwater pollution. This study makes a groundwater vulnerability assessment for the Pingtung Plain using an improved overlay and index-based DRASTIC model. The improv...
