Rescue and relief begin after occurrence disaster and continues until the border of reconstruction phase. Assessing the quality of the rescue and relief phase can be done by considering qualitative and quantitative variables. Qualitative variable use to evaluate performance of this phase of managing of disaster .These kinds of variables measured condition without interference of quantities data. Result of using qualitative assessment can present in indexes such as satisfaction of damaged people and acceptability of operation in people which are in damaged zone or in other areas. In this research by definition qualitative Indexes which can be used after an earthquake disaster, assessing the performance of the rescue and relief phases by using these Indexes was done. For receiving the objective of this study a new method was suggested. Step by step method is one method which can be used in assessing the quality performance of disaster management. Result of this research acknowledges that qualitative assessment has permissible consequence and can be done in measuring the rate of efficiency of rescue and relief phase of disaster management.<\div>

Nowadays, with the ever–increasing growth of the population and thedevelopment of various industries, we are experiencing an increase inenvironmental problems, resulted from man–made contaminants (such as urbansolid wastes, wastewater, etc).Generally, the ease of the exposure of groundwater to aquifers is determined bythe vulnerability of these waters. The vulnerability assessment is a processthrough which we can distinguish those areas with the lower vulnerability fromthe ones with the higher vulnerability. Hydro geological parameters which areeffective in polluting ground waters and also presented in Modified DRASTICmodel involve: Depth to groundwater surface (D), Recharge (R), Soil media (S),Topography (T), Impact of vadose zone (I) ,Conductivity of aquifer Hydraulic(C),the effect of Land use activity(L).This study aims at zoning the pollution potential of Mashhad aquifer by using theModified DRASTIC method and GIS software in order to locate and select somenew landfill sites as well as to assess the previous existing ones.The results showthat new and existing landfill sites for solid waste disposal in Mashhad siteselections were wrong, while they are located in high vulnerability zones andwhere the risk of groundwater pollution is high.<\div>

Groundwater quality regarding major anions and cations in the Birjand Plain located in the largest desert in Eastern Iran was monitored in this study. Fifteen boreholes were considered as sampling stations and the parameters pH, TDS, EC and major anions and cations were measured in groundwater samples. The dominant groundwater types can be introduced as sodium–chloride and magnesium–sulphate. The majority of samples were within the not–suitable category for drinking uses. Regarding agricultural use, around 80 and 50 per cent of samples indicated a very high salinity hazard and a very high sodium alkali hazard, respectively. Spatial distribution of salinity was also monitored within the study area. If the study area was considered to be a semicircle, the centre appeared to be the least polluted area, while towards the peripheral surroundings, an increasing behaviour was observed. Intrusion of salt water from eastern and western parts of the study area caused severe groundwater degradation. The relatively better quality of groundwater in southern areas may be attributed to a chain of mountains located along south of the study area. The prevention of uncontrolled groundwater withdrawal must be regarded to cease the salinization trend and to prepare the required infrastructure for implementing the artificial recharge projects.
