Karst groundwater in the Niangziguan spring fields is main source to supply domestic and industrial water demands Yangquan City, China. However, safety of this region has recently suffered from deteriorating quality levels. Therefore, identifying pollution sources causes crucial for maintaining a reliable supply. In study, systematic sample collection karst was implemented identify hydrochemica...

Recently one of the most prominent activity focusing in Indian cities is the retrofitting the urban drainage system. Millions of rupees spent on the construction of stormwater drains in towns and cities to prevent flooding during the rains. These drains that extend several kilometers across the town or city are expected to feed all the collected surface runoff into the nearest surface water bod...

BACKGROUND Studies of water-related gastrointestinal infections are usually directed at outbreaks. Few have examined endemic illness or compared rates across different water supply and sewage disposal systems. We conducted a cohort study of physician visits and hospitalizations for endemic intestinal infectious diseases in a mixed rural and urban community near Vancouver, Canada, with varied an...

the main objective followed in this research was to study some of the factors influencing water users' participation in management of the irrigation and drainage networks on the lands under jiroft dam. the kind of research method of the study was a descriptive- correlational one. the statistical population of the study consisted of all the water users of irrigation and drainage networks ac...

-Water pollution has become one of the most serious problems of today’s civilization. In the last few years considerable amount of research has been done on the potential of aquatic macrophytes for pollutant removal or even as bio-indicators for heavy metals in aquatic ecosystems. Water hyacinth is one of the aquatic plant species successfully used for wastewater treatment. It is very efficient...

In arid and semi-arid areas, low soil fertility and water deficit considerably limit crop production. The use of sewage sludge as an organic amendment could contribute to the improvement of soil fertility and hence the agronomic production. The study aims to highlight the behaviour of durum wheat to the application of sewage sludge associated with water stress. The assessment focused on morphop...

Great attention has been paid to the potential of wastewater irrigation as a sustainable water source, particularly due to water scarcity and water pollution issues. However, few studies have focused on its adverse effects and on the health risks it may pose. In this study, the physicochemical properties of soils and plants irrigated with rural domestic wastewater and associated microbiological...

Microbiological source tracking (MST) methods are increasingly being used to identify fecal contamination sources in surface waters, but these methods have been subjected to limited comparative testing. In this study, 22 researchers employing 12 different methods were provided sets of identically prepared blind water samples. Each sample contained one to three of five possible fecal sources (hu...

In the study, Drainmod model was used to compare measured water table depth fluctuations on the farm with those simulated by the model, also comparison of measured drainage outflow of the farm drains and model simulated was investigated. This study was made in a part of the Irrigation and Drainage Network of ABADAN Date palms. By statistical analysis of the measured and predicted water table de...
