The research area of this study is the city of Khorramabad . The data of this study are 23 wells and springs in Khrorramabad and from 1381 to 1392, which is seasonal. Information and data on the chemical elements present in the water parameters: ph., total hardness (TH), electrical conductivity (EC), Total Dissolved Solids (TDS), sulfate (SO4), chlorine (Cl), nitrite (NO2) and nitrate (NO3). . The results showed that Ph. of all wells and springs allowed within acceptable limits and standards. The total hardness (TH) is higher than the desirable standards in all seasons in all of resources and is lower than the allowed maximum of standards. According to the conducted researches, the amount of the electrical conductivity, total dissolved solids (TDS) and sulfate (SO4) are lower than optimum and maximum in all wells and springs in all seasons. The amount of chlorine (Cl) in all wells and springs is lower than the limit on the number of allowable standards but is higher than the desirable standard of EPA. In all seasons the amount of nitrate (NO3) on all resources is lower than the allowed Iranian national limit, and desirable and permissible World Health Organization (who), and the limit of EPA standard, but in all of the resources is higher than the desirable limit of (EPA). Also, in all seasons, the amount of nitrites (NO2) in all wells, springs and the study area is lower than the standards.

Abstract Background: Zone 3 of Zahedan City includes the most deprived areas in province and country. The purpose of this research was assessing the distribution of the health care center (hospitals) and determining the underserved areas based on hospital locating concidering standards and criteria. Materials and Methods: In order to achieve accurate results based on GIS software, spatial and descriptive data using statistics and field observation gathered and connected to database. Besides, AHP Model used to set priorities in locating the optimal urban spaces for building hospitals in the city. Results: Suitable zone with special symbol severance divide from another zones was determine to develop landuse based on dependency to health care centers aimed at providing services in local level . Similarly, two Places recommended constructing health care centers in complete suitable zone. Unsuitable and compeletly Unsouitable zones was determined in zone three of zahedan city in finaly map. Conclusion: study analysis based on urben percapita, population and needed availibilty to health care centers suggests that Zahedan city need two new hospitals setting which has been indexed on final map.

Water shortage is one of the most important environmental challenges in arid and semiarid regions. Unfortunately, today, due to low precipitation and over pumping of groundwater resources in recent years and also lack of attention to aquifer and artificial feeding; therefore more attention to ground water resources is an inevitable and important issue. The review of quantitative and qualitative situation of the underground water tables is of such issues which shall be considered. In this study, the qualitative and quantitative variations of the groundwater water tables have been investigated for feeding and discharge in some pizometers of Jovain prolific plains in south Khorasan province. Firstly, the data statistics of hydro static levels at 50 pizometers as quantitative and at sixty pizometers as qualitative were prepared as selected pizometers and sufficiency and homogenous tests of the data were performed. Then the imperfect data were reconstructed and finally the data were extracted and analyzed in 12 years common statistics base of 1995-2007. The aim of this paper is to determine the qualitative and quantitative maps of underground waters based on the variables of hydrostatic levels through inverse distance interpolation method (ID) by the use of GIS system (Geographical Information System). So that, based on the results of mapping Annual Groundwater Unit Hydrograph (AGUH) of Jovain province, on average the water ground level from years of 1995 to 1999 up to aqueous year 2006-2007 shows a drop of 10 m. Also the Annual Groundwater Unit Hydrograph (AGUH) of Jovain plain and three periods of diverse drop of hydrostatic level from years 1995 up to 1998 from 53.07 to 54.09m shows approximately a normal drop status. But from statistical year 1998 on ward up to year 2003, the drop has reached from 53.07 to 54.09 m, that is 4.5 m of drop during four aqueous years. With respect to the obtained results of analysis of quantitative and qualitative results by Inverse Distance Interpolation Method (ID) and mapping qualitative and iso- drop maps , the interpolated qualitative parameters are critical in some areas and show a drastic decrease of quality of this aquifer.
