Environmental studies of motor vehicles typically focus on air pollution or noise, but ignore water pollution. In this paper, we examine some of the impacts of motor vehicle transportation on non-point source and on groundwater pollution. Our estimates of the present value of costs for cleaning up leaking underground storage tanks and for controlling highway runoff for major arterials range fro...

Background: Chronic arsenic pollution is now recognised as a worldwide problem, with 21 countries experiencing arsenic groundwater contamination. It is a particularly important issue in developing countries, where groundwater is generally the preferred drinking source (as an alternative to polluted surface water). Technologies to remove or mitigate arsenic contamination of groundwater include p...

The large number of municipal solid waste (MSW) landfills and the many hazardous materials which they contain pose a serious threat to both surrounding environment and human populations. Once waste is deposited at the landfill, pollution can arise from the percolation of leachate to the porous ground surface. Contamination of groundwater by such leachate renders it and the associated aquifer un...

A considerable number of studies have been made of institutional arrangements that can prevent excessive groundwater pumping based on Hardin’s seminal work, the “tragedy of the commons.” In contrast, this paper is concerned with groundwater quality control for which policy studies are very limited. This paper not only clarifies institutional challenges specific to groundwater contamination, but...

Agricultural-induced increase of nitrate (NO3) loading in groundwater is a worldwide problem. This study investigates the impacts of agricultural activities on groundwater NO3 pollution in a Yellow River irrigated region. The agricultural land use patterns are dependent on the land and water conditions. Besides wheat–maize rotation, the most popular cultivation pattern, other patterns with high...

Leachate and groundwater samples were collected from Gazipur landfill-site and its adjacent area to study the possible impact of leachate percolation on groundwater quality. Concentration of various physico-chemical parameters including heavy metal (Cd, Cr, Cu, Fe, Ni, Pb and Zn) and microbiological parameters (total coliform (TC) and faecal coliform (FC)) were determined in groundwater and lea...

background: iran is located within the dry and semi dry regions, thus almost 90% of the required water is secured via the use of groundwater. owing to the increasing pollution of water resources, this study was performed to evaluate water quality pollution indices for heavy metals (as, zn, pb and cu) contamination monitoring in toyserkan plain during spring and summer in 2012. methods: a total ...

In the absence of available surface water in semi-arid areas, groundwater has become the main water resource for various purposes. In many places in southern India, groundwater even is the only source of drinking water in rural areas. Therefore, quality and quantity aspects of groundwater management constitute acute issues for the well-being of Indian rural populations. This study proposes to u...
