groundwater quality assessment and selection of appropriate methods of zoning depends on the region conditions, and data availability. the correct choice is a key milestone and a major step forward in the management of groundwater resources. the aim of this study was to evaluate the quality of groundwater for drinking and irrigation purposes in the west of marivan city, iran. for this purpose, ...
BACKGROUND Bacteria used as indicators for pathogenic microorganisms in water are not considered adequate as enteric virus indicators. Surface water from a tropical high-altitude system located in Mexico City that receives rainwater, treated and non-treated wastewater used for irrigation, and groundwater used for drinking, was studied. METHODS The presence of enterovirus, rotavirus, astroviru...
Aims & Backgrounds: One of the most important parts of Planning and management in arid areas is land evaluation surveys and determines the compatibility of the desired area for previously considered land use. The purpose of this research is to emphasize the importance and role of land suitability assessment classification as one of the main parts of management in this region. Methodology: In t...
According to Italian Ministerial Decree No. 185 of 12 June 2003, water is considered suitable for irrigation if levels of fecal bacteria (i.e., Escherichia coli and Salmonella) are within certain parameters. The detection of other microorganisms is not required. The aim of this study is to determine the bacteriological quality of groundwater used for irrigation and the occurrence of enteric vir...
Background and Objectives: Fluoride has both beneficial and detrimental effects on health. Therefore, it is important to determine its concentration in drinking water. Dental fluorosis and skeletal fluorosis are health effects caused by long term exposure to high levels of fluoride in drinking water. The aim of this research was to investigate fluoride removal using modified diatomite-supported...
In order to assessment of SDI system application in the condition of wastewater reuse, three treatments with three replications were design. These treatments included check treatment with drinking water (CH), surface drip irrigation with wastewater (DI) and subsurface drip irrigation with wastewater (SDI). In addition, before pipeline, a SDI filtration designed to improve biological index of wa...
Introduction: Being located in an arid and semi-arid region, Iran has always faced with limited water resources. As groundwater extraction has now exceeded the permitted limits all over Iran and the country faces considerable constraints in developing groundwater resources, severe water crisis looms large in the horizon. In this regard, a quick solution should be considered to supply water from...
Economic development and human life depend on groundwater resources in arid regions around the world. To define water quality Northwest Gulf of Suez, its elements, geogenic anthropogenic sources, suitability for various purposes, ten samples were collected analyzed from wells tapping Quaternary Tertiary aquifers. Average ion distribution was following order: Na+ > Mg2+ Ca2+ K+ Cl− SO42− HCO3...
