“…On the other hand, they are related to the concentration of the dissolved minerals in water which is an intrinsic property of each site and did not considerably differ from the springs to the pools. Generally, the physical-chemical properties of thermal springs are most dependent on geological, lithological, and tectonic parameters, and these kinds of parameters markedly vary in different areas (Tanasković et al 2012) and hence the influence of site as observed in our results.…”

Microbial quality and physical-chemical properties of recreational spas were surveyed to investigate the health aspect of the spas' water. A total of 195 samples were collected from pools and springs of the spas in five sites from Ardebil Province of Iran. The effects of an independent factor defined as 'condition' and its component sub-factors (i.e., sampling point, location, and sampling date) on microbial quality and physical-chemical properties of the spas were studied by applying path analysis. The influence of physical-chemical properties on microbial quality was also considered. The percentage of samples exceeding the ISIRI (Swimming pool water microbiological specifications (vol 9412), Institute of Standards and Industrial Research of Iran, Tehran, 2007) limits for Staphylococcus (spp.) was up to 55.8 in the springs and 87.8 in the pools, 58.1 and 99.2 for HPC, 90.7 and 97.8 for total coliform and fecal coliform, and 9.3 and 34.4 for Pseudomonas aeruginosa, respectively. There were significant differences between the pools and springs for both physical-chemical properties and microbial quality. From the path analysis, sampling point was the most effective sub-factor of 'condition' on both the physical-chemical properties and microbial quality. Among the physical-chemical properties, water color had the most enhancing or additive influence on microbial pollution, while EC indicated a reducing or subtractive effect.

“…As seen in Table 5, there exists a strong positive correlation (r=0.72) between 232 Th and 226 Ra, while a very weak negative correlation is observed between 40 K and these two (r=0.093 for 40 K and 226 Ra; −0.018 for 40 K and 232 Th). These degrees of association among the radionuclides may be because radium and thorium decay series come from the same origin and exist together in nature, whereas potassium is from a different origin (Tanasković et al 2012). Furthermore, the measured absorbed dose rates have a very strong positive correlations with 226 Ra and 232 Th (r=0.82 and 0.92,respectively).…”

Understanding the public awareness concerning the Lynas Advanced Material Plant (LAMP), an Australian rare earths processing plant located in Malaysia, a radiological study in soil and water samples collected at random surrounding the LAMP environment was undertaken using HPGe gamma-ray spectrometry. The mean soil activities for (226)Ra, (232)Th, and (40)K were found to be 6.56 ± 0.20, 10.62 ± 0.42, and 41.02 ± 0.67 Bq/kg, respectively, while for water samples were 0.33 ± 0.05, 0.18 ± 0.04, and 4.72 ± 0.29 Bq/l, respectively. The studied areas show typical local level of radioactivity from natural background radiation. The mean gamma absorbed dose rate in soils at 1 m above the ground was found to be 11.16 nGy/h. Assuming a 20 % outdoor occupancy factor, the corresponding annual effective dose showed a mean value of 0.014 mSv year(-1), significantly lower than the worldwide average value of 0.07 mSv year(-1) for the annual outdoor effective dose as reported by UNSCEAR (2000). Some other representative radiation indices such as activity utilization index (AUI), H ex, H in, excess lifetime cancer risk (ELCR), and annual gonadal dose equivalent (AGDE) were derived and also compared with the world average values. Statistical analysis performed on the obtained data showed a strong positive correlation between the radiological variables and (226)Ra and (232)Th.

“…Based on the position in the van Wirdum's diagram, the groundwater can be classified as atmospheric, At (rainwater), lithotrophic, Li (calcium-rich freshwater), thalassotrophic, Th (seawater) or anything in between, such evaporite deposits effect. The samples are distributed among the three reference water types from the hydrological cycle (Tanaskovic et al 2012). The samples are distributed among the three reference water types from the hydrological cycle.…”

Evaluation of groundwater chemistry and its suitability for drinking and agricultural uses in the Lenjanat plain, central Iran

Study of the 59 groundwater samples from Lenjanat area, central Iran, was carried out in order to assess their chemical compositions and suitability for drinking and agricultural purposes. Based on Gibbs' diagram, weathering of rocks and evaporation were found to be the dominant processes in the ion concentration of the water samples. The saturation index calculated through geochemical modeling indicates a suitable chemical environment for anhydrite, aragonite, calcite, dolomite, fluorite, and gypsum dissolution in both wet and dry seasons. All samples have the SO 4 2-? HCO 3 -more than 5 meq/l indicating that in addition to calcite and dolomite, dissolution of gypsum is the probable process in this plain. Assessment of the concentration of Mg 2? ? Ca 2? proportion to SO 4 2-? HCO 3 -demonstrates that the advanced direct and reverse ion exchange between groundwater and surrounding environment has occurred. The Chadha diagram indicates that the amount of earthalkali parameters is more than alkali ones and by considering the high value of strong acids, the dominant hydrochemical facies in both wet and dry seasons are Ca 2? -Mg 2? -Cl --SO 4 2-. According to pollution index, in the selected time domain, all samples are in safe conditions. Calculation of entropy weighted water quality index for groundwater samples demonstrates that in the wet and dry seasons, over 57 and 42 % of the samples are in the range of ''excellent'' to ''medium'' quality, respectively. The values of SI, RSC, SSP, SAR, KR, PI, MAR, and CI show that 90 and 85 % of the samples in wet and dry seasons have the good quality for agricultural purposes.
