one of the biggest barriers for agricultural production in iran is water deficit. however, certain optimum approaches for water application can solve this problem. deficit irrigation technique is an approach that could have a better and economic use of water in agriculture. in this regard, a research with three factors including two irrigation intervals of 8 and 12 days, two nitrogen fertilizer...

In the present data article, fluoride concentration levels of drinking water (with spring or groundwater sources) in 10 villages of Asara area located in Alborz province were determined by the standard SPADNS method using a spectrophotometer (DR/2000 Spectrophotometer, USA). Daily fluoride intakes were also calculated based on daily drinking water consumption. The fluoride content were compared...

The urgent demand of integrated water resources management has drawn attention to the issue of transnational water bodies that comprise exploitable resources for two or more countries. It is estimated that 50% of the global surface is lying on transboundary catchments and this percentage is continually increasing due to the creation of new nations, while around 40% of the earth’s population res...

Faecal pollution in stormwater, wastewater and direct run-off can carry zoonotic pathogens to streams, rivers and the ocean, reduce water quality, and affect both recreational and commercial fishing areas of the coastal ocean. Typically, the closure of beaches and commercial fishing areas is governed by the testing for the presence of faecal bacteria, which requires an 18-24 h period for sample...

[1] Chile’s free-market Water Code turned 20 years old in October 2001. This anniversary was an important milestone for both Chilean and international debates about water policy because Chile has become the world’s leading example of the free-market approach to water law and water resources management, the textbook case of treating water rights not merely as private property but also as a fully...

Public concerns over potential environmental contamination associated with oil and gas well drilling and fracturing in the Wattenberg field in northeast Colorado are increasing. One of the issues of concern is the migration of oil, gas, or produced water to a groundwater aquifer resulting in contamination of drinking water. Since methane is the major component of natural gas and it can be disso...

Background: Application of membrane technology to wastewater treatment has expanded over the last decades due to increasingly stringent legislation, greater opportunities for water reuse/recycling processes and continuing advancement in membrane technology. Objectives: In the present study, a bench-scale submerged microfiltration membrane bioreactor (MBR) was used to assess the treatment of tex...
