The purpose of the paper is to assess the groundwater quality near the landfill sites using landfill water pollution index (LWPI). In order to investigate the scale of groundwater contamination, three landfills (E, H and S) in different stages of their operation were taken into analysis. Samples of groundwater in the vicinity of studied landfills were collected four times each year in the perio...
abstract governing was disorganized for years, when mongols attached to iran and it caused to clearing way for interference of mongols princes. dispatching of holaku to the west culminated in establishing iilkhanan government. holakus activities in destruction of abbaasis government and activities which shows his staying in iran, made force oulus juji to comparison against iilkhanis gover...
An extensive survey of groundwater quality was performed at the regional scale in peri-urban and industrial contexts Walloon Region (Belgium). To this end, 243 sampling locations from 8 areas located different geological region were sampled outside pollution hotspots related to contaminated sites. Each sample analyzed for 19 inorganic trace elements, 59 organic micro-pollutants major minor elem...
Nowadays, the increase in population growth rate and followed by anthropogenic activities such as urbanization, industrialization, mining and agriculture practices continuously increase the amount of heavy metals in the environment especially groundwater resources. Therefore, qualitative assessment of groundwater resources is of great importance for maintaining public health and for this reason...
Monitoring of Meteorological and groundwater droughts and determining of the lag time between these two types of droughts in spatial various locations can help in consumption management and protection of the groundwater resources. In this study, spatial and temporal changes of droughts were analyzed using the Standard Precipitation and Groundwater Resource Indices (SPI & GRI) in the northern Ma...
introduction: in recent years, due to the reduction in surface water, utilization of groundwater has been increased to meet the growing demand of irrigation water. the quality of these water resources is continually changing, due to the geological formations, the amount of utilization, and climatic parameters. in many developing countries, the irrigation water is obtained from poor quality grou...
The purpose of this research is the investigation of Kashan aquifer situation, the depth of bed rock, thickness of aquifer saturation layer, boundary of salt water and the investigation of sediment permeability in Kashan plain using electric resistance with Schlumberger arrangement. In this study, 41 Latitudinal profiles and 1 longitudinal profile were used in order to evaluate aquifer situatio...
