The acceleration of urbanization and rapid development of economy led to making surface water pollution problem becoming more critical. Water treatment technologies can be generally classified as insitu or ex-situ. In this paper, a comprehensive review describing the latest surface water remediation developments and technologies that can be suitable for in-situ applications. The review covers t...

Few studies have examined the impacts of ground water quality on residential property values. Using a unique data set of well tests, we link residential real estate transactions to home-specific contamination and conduct a hedonic analysis of sales in Lake County, Florida, where pollution concerns relate primarily to agricultural run-off. We find that recent testing and contamination of ground ...

The safety of groundwater resources is a serious issue, particularly when these resources are the main source of water for drinking, irrigation and industrial use in coastal areas. In Italy, 85% of the water used by the public is of underground origin. The aim of this report is to analyze the main factors that make groundwater vulnerable. Soil characteristics and filtration capacity can promote...

This paper summarizes the currently available information on gasoline exposure to the general population. In general, the largest contribution to the time weighted exposures results from exposures while indoors, which are influenced by the outside air, indoor sources, and attached garages. Personal activities, including refueling and commuting, contribute significantly higher exposures but last...

The problem of chemically contaminated water supplies are in general terms followed by a description of three examples of water supply problems in China. A large-scale prospective epidemiological study, now in the early planning stages, to be carried out in China is also described.

drinking water contaminated by cholera feces. Mettupalaiyam is the south-west terminus of the Madras Railway. It comprises three villages,?Odandurai in the north, Kariyampalayam in the middle, and Chikkadasampalayam in the south. The river Bhavani, which runs through the town from west to east, separates Odandurai from Kariyampalayam. Thus Odandurai lies on the northern bank of the river Bhavan...

Intensive crop production involves a high consumption of pesticides. This is a cause of major environmental concern because the presence of pesticides in water is becoming increasingly common. Physicochemical methods based on soil modification with organic residues have been developed to enhance the immobilization and/or degradation of pesticides in agricultural soils, which may control both th...

In April 1994, chemical contamination of the River Severn aVected the water supply to a population of 160 000 in Worcestershire. During the incident the health authority free phone emergency helpline received 106 complaints of symptoms attributed to consumption of contaminated water. These complaints were important as they alerted the emergency incident team to the possibility of illness being ...

Affected by regular tides, bidirectional water flows play a crucial role in surface river systems. Using optimization theory to design a water quality monitoring network can reduce the redundant monitoring nodes as well as save the costs for building and running a monitoring network. A novel algorithm is proposed to design an optimum water quality monitoring network for tidal rivers with bidire...

The response of two dominant coniferous species (Picea obovata Ledeb. and Pinus sylvestris L.) of eastEuropean taiga to industrial pollution in the impact zone of the Severonickel metallurgical combine (Murmansk Region, Kola Peninsula) was investigated. The water deficit of the needles and shoots described by shoot water potential ( ) was used as indicator of the pollution level in the area. Th...
