  Background and Objective: Development of agriculture, industry and population growth, the exploitation of groundwater resources has increased and has affected its quality. In order to prevent the occurrence of quantitative and qualitative problems of aquifers, management of optimal operation of groundwater resources is essential. Therefore, the purpose of this study is the optimal utilization of groundwater resources and to investigate its quantitative and qualitative effects on the Shahriar plain aquifer. Material and Methodology: Groundwater level changes and its quality from the perspective of index (TDS) in Shahriar plain aquifer have been simulated by ANN. Then (TDS) of groundwater has estimated by regression. Finally, the multi-objective genetic algorithm (NSGA-II) was used for optimal utilization of groundwater resources and with the aim of minimizing groundwater level changes and total dissolved solids of groundwater. Findings: According to the results of the study, the evaluation criteria (RMSE) in three modes of training, testing and validation for groundwater level changes are equal to 1.27e-06, 0.0025 and 0.003, respectively, and for total dissolved solids of groundwater was calculated to be 0.24, 27.64 and 14.608 and the correlation coefficient (R) at the level (0.05) in three situations was significant for both variables. Also, during the study period, the volume of optimal withdrawal from the aquifer has decreased by 29.12 percent and the optimal amount (TDS) of groundwater on average, 120.87 Mg./l, has been calculated less than the estimate of artificial neural network. And Groundwater level has also increased by an average of 9.27 meters per year. Discussion and Conclusion: The results confirm that the proposed simulation-optimization method as an application tool with good performance, low cost and desirable speed can support several effective factors simultaneous with optimal operation policy. It also reduces the quantitative and qualitative problems of the aquifer and cause increases the stability of the groundwater system.   Manuscript profile

  Iran is located in the dry and semi dry zone of the world and almost 90% of its drinking waterrequirement is supplied from groundwater resources. Considering the increase of pollution and declineof groundwater resources quality due to agricultural and industrial activities and urban development,this study was conducted to evaluate As, Zn, Cr and Mn concentrations in groundwater resources ofRazan plain and to prepare the zoning map during spring and summer in 2012. For this purpose,samples were randomly collected from 20 wells across the plain, and pH and temperature parameterswere measured in situ. Concentration of heavy metals in groundwater samples was cited by AtomicEmission device after laboratory preparations. The results showed that the mean concentrations of As,Zn, Cr and Mn in the samples were respectively 5.86±0.69, 30.28±3.42, 0.044±0.005, and 3.69±0.40ppb in spring and respectively 6.83±0.68, 34.50±3.11, 0.046±0.006 and 4.50±0.51 ppb in summer.Moreover, comparison of heavy metals mean concentrations with WHO permissible limits showedthat they were lower than standard levels. The results from comparison of variations in heavy metalsmean concentration in two seasons revealed the lack of meaningful difference (p<0.05). Thedetermined correlation between pH, water temperature and heavy metals mean concentrationaccumulated in the samples indicated no correlation between parameters and heavy metalsaccumulated concentration.Although the groundwater resources in Razan plain are not currently over polluted with heavy metals,long-term and excessive use of agricultural inputs as well as construction of polluting industries canthreaten the groundwater resources of this area in addition to bearing some irretrievable consequences.

  Background and Objective: Providing safe drinking water is so essential for human consumption adequately and healthy. Therefore, knowledge of the physicochemical quality of water resources can play a major role in their utilization and consumption for drinking. Measurement and monitoring of water quality parameters is the first step for ensuring safe water. The aim of this study was to investigate the quality of drinking water wells of Zarghan plain in Fars province.Methods: For this purpose, the data of meteorology, groundwater level and physicochemical experiments of 12 parameters including Total Dissolved Solids, Total Hardness, Electrical Conductivity, pH, Sulfate, Bicarbonate, Nitrate, Sodium, Calcium, Magnesium, Chloride and Fluoride of ten drinking water wells in Zarghan rural district during 2011-2016 were used.Findings: Data were analyzed by Pearson correlation matrix and one sample t-test using SPSS software. The results of comparing different parameters of water wells in Zarghan area with the national standard during 5-year-period showed that with decreasing groundwater level due to drought, the amount of Magnesium, Chloride, Sodium, Total Hardness and Electrical Conductivity increased and exceeded the maximum standard limit for drinking.Discussion and Conclusion: Water wells no. 1, 2, 4 and 7 have a better level of drinking water quality than water wells no. 5, 6, 9 and 10 due to decreasing rain and drought, uncontrolled harvesting of groundwater resources, and differences in the matter nature and type of soil of each part of the area.

  Nitrate and nitrite ions are important pollutants of surface waters and groundwater resources which can have adverse effects on the health of consumers. Therefore the purpose of this study was determination of nitrate and nitrite concentrations in groundwater resources of Dehgolan City.Groundwater samples were collected from20 selected stations during before and after of fertilization periods in 2012. The samples are prepared according to APHA method and concentrations of nitrate and nitrite anions analyzed using spectrophotometer on the wavelengths of 420 and 543 nm respectively. All statistical analyses were performed using the SPSS statistical package.The results showed that mean concentrations of nitrate and nitrite anions in groundwater samples for before fertilization period were 8.66±0.97 and 0.001±0.0003 mg L-1, respectively, and for after fertilization period were 69.20±8.82 and 0.013±0.006 mg L-1, respectively. Also comparison of the mean concentration of nitrate in groundwater samples after fertilization period with Iran DOE permissible limits for drinking use showed that significant difference (p<0.05). So that the mean concentration of nitrate significantly upper than permissible limits.Conclusion: According to the results of this study because of the mean concentration of nitrate significantly upper than permissible limits, therefore long-term excessive use of agricultural inputs and construction of polluting industries, can cause a threat to groundwater resources, and health of residents in this area.

  Maintaining food security is one of the requirements of development, but agricultural development policy has led to unsustainable development in Iran. The purpose of this research is to identify the impact of agricultural development on the instability of groundwater resources. Most studies have criticized the government management in the field of agricultural hardware; however, this article studies the research community along with evaluating the unilateral role of government in policy advice, and methods of sustainable agricultural development to conserve groundwater resources. The analytical method has been used in the present study. Among the goals of sustainable development in the UN document, economic growth and agricultural promotion along with sustainable water use has been selected.Based on the development plans of Iran as an upstream document, can be concluded that since we have practically witnessed the imbalance of production and consumption, the agricultural development policy of the government has violated the standards of sustainable development by ignoring stakeholder participation in maintaining water inventory. In the end, with understanding the importance of the water cycle as one of the requirements of sustainable development, it is suggested that by relying on good governance and integrated management, we can use the previous researches and local actors to achieve sustainable agricultural development.
