Short description Urban sprawl is eroding the traditionally compact, diverse, and mixed Southern European cities. Besides the rise in land and energy consumption, the expansion of low density urban forms also affects water, a critical resource in the region. The main purpose of the presentation is to examine how physical, but also economic, social and cultural processes are behind the current u...

Infrastructure for the provision of drinking water and the treatment of wastewater and stormwater, is essential for an urban society. In this project methods are developed which measure and assess the sustainability of urban water systems. A first set of environmental sustainability indicators (ESIs) was constructed, covering technical and environmental aspects, with a division within tradition...

Medical centers (that is, hospitals and clinics) in metropolitan areas produce substantial amounts of hazardous waste in both solid and liquid (wastewater) forms. Unless medical centers manage their waste with appropriate care, the significant hazards posed to urban residents and areas far outweigh the benefits of their services. Therefore, comprehensive environmental management programs need t...

background : the present paper aims to study the effect of human and urban activities on the quality of groundwater within the city of khoy in terms of heavy metals, chemical salts, and minerals from the geological formations of this region. methods : samples were provided from 32 pumping wells and the concentration of heavy metals ( cd, cu, mn, pb, zn, fe, as, and b), the main ions (hco 3 ,so ...

Victoria Harbour has received substantial loadings of pollutants from industrial and municipal wastewater discharged since the 1950s. Inputs of contaminants have declined dramatically during the last two decades as a result of better controls at the source and improved wastewater treatment facilities. To assess the spatial and temporal changes of metal contaminants in sediments in Victoria Harb...

recycling and reuse of wastewaters are of the new policies that provide water resources to respond to the need of the growing population. in many societies, social acceptability of these processes has an important role in the success of the reuse from refined wastewater, because the final product of this process is in direct relation with the consumer. therefore, social and cultural implication...

Treatment of domestic wastewater, at both the village and urban level, remains a problem in most developing countries. This is a review paper illustrating the use of duckweed-based wastewater treatment systems that provide genuine solutions to these problems. They are inexpensive to install as well as to operate and maintain. They do not require expensive technologies. Therefore, this review pa...

While studies have documented the presence of pyrethroid insecticides at acutely toxic concentrations in sediments, little quantitative data on sources exist. Urban runoff, municipal wastewater treatment plants and agricultural drains in California’s Sacramento-San Joaquin River Delta were sampled to understand their importance as contributors of these pesticides to surface waters. Nearly all r...
