There are few studies examining the impacts of groundwater quality on residential property values. Using a unique dataset of groundwater well tests, we link residential transactions to home-specific contamination levels and undertake a hedonic analysis of homes in Lake County, Florida; where groundwater pollution concerns stem primarily from agricultural runoff. We find that testing and contami...

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 Ciric and Khore Azini international wetland is the only unique habitat of Rizophora mucronata in Iran. Due to the limited access and difficulty of sampling, a study has not been done about the amount of heavy metal contamination in the plant community in this region. For this purpose, in 2016, 27 sediments, leaves and roots were sampled from 9 stations with three replications at each statio...

Decontamination, i.e. cleaning by removal of chemicals or germs, is a term commonly used for the process of treating devices, instruments and surfaces in order to ensure their safe operation. It is of exceptional importance in healthcare, food and pharmaceutical industry as well as in the areas of army and public defense. The decontamination process covers several steps like simple washing with...

Contamination of the environment in Kuwait occurred in 1990-1991 during the Iraqi invasion and due to explosion of more than 700 oil wells. Oil contamination caused serious damage to the environment. This study was conducted to estimate the extent and volume of contaminated soil by using remote sensing, GIS application and field survey.. A map of the area was developed by GIS showing four types...

Solid waste management has moved to the forefront of the environmental agenda. Nations are considering restrictions on packaging and controls on products in order to reduce solid waste generation rates. Local and regional governments are requiring wastes to be separated for recycling, and some have even established mandatory recycling targets. However, industrial and everyday activities continu...

Having the ability to identify areas of land that are vulnerable to ground water contamination should facilitate the development of management and regulatory options that may be used on a regional scale. The prevalent approach to modelling land areas has been to identify contamination processes deductively and then construct theoretical models comprised of pertinent variables. Most models for p...

Objective: Metal concentrations in 53 soil samples of Shahr-e-Babak were determined.  Methods: Assessment of enrichment factor and geo-accumulation index revealed higher degree of contamination of Cd, Pb, and Cu in soil samples. Moreover, results of metal fractionation study revealed high amount of Cd and Pb are associated in weakly bounds may lead to environmental risk of these metals.  Result...
