A river intensively used along its entire course for extracting potable water and for discharging domestic and industrial effluents permanently carries a high load of viruses, including hepatitis A and rotaviruses. In the areas supplied with potable water from this river hepatitis A is endemic. The river has been investigated four times at 16 or more sampling points throughout its course in the years 1981, 1982 and 1983. Coincident with the virological investigation, biological, microbiological and chemical examinations were conducted with the same water sample. At some representatively distributed sampling points along the river course, tests for heavy metals (Cd, Ni, Cu, Cr, Pb) and selected chemical compounds were also performed. The virological quality of the river water largely depends on the virus input via domestic sewage. Statistically significant correlations have been found between virus level, pH, NH4+ and NO3−. Amoebae species are likely to counteract viruses. Knowing the dynamics of river water exploitation above the extraction sites, a model for the estimation of virus content in the raw water could be developed.

Abstract. This study presents strontium isotope and major ion data of shallow groundwater and river water from the Ile du Chambon catchment, located on the Allier river in the Massif Central (France). There are large variations in the major-element contents in the surface- and groundwater. Plotting of Na vs. Cl contents and Ca, Mg, NO3, K, SO4, HCO3, Sr concentrations reflect water–rock interaction (carbonate dissolution for Ca, Mg, HCO3 and Sr because the bedrock contains marly limestones), agricultural input (farming and fertilising) and sewage effluents (for NO3, K, SO4), although some water samples are unpolluted. Sr contents and isotope ratios (87Sr/86Sr vary from 0.70892 to 0.71180 along the hydrological cycle) in the groundwater agree with previous work on groundwater in alluvial aquifers in the Loire catchment. The data plot along three directions in a 87Sr/86Sr v. 1/Sr diagram as a result of mixing, involving at least three geochemical signatures–Allier river water, and two distinct signatures that might be related to different water-rock interactions in the catchment. Mixing proportions are calculated and discussed. The alluvial aquifer of the Ile du Chambon catchment is considered, within the Sr isotope systematic, in a larger scheme that includes several alluvial aquifers of the Loire Allier catchment. Keywords: : Loire river, major and trace elements, Sr isotopic ratio, alluvial aquifer, hydrology

The sustainability of watershed ecosystem functions in managing the water system can be achieved if the utilization pattern of their territories in accordance with the rules of conservation. A decrease in quantity and quality of the river water can be an indicator that condition of the watershed have been damaged. The destruction of the watershed ecosystem as a result of various causes will be able to threaten supply of sustainable water resources. The aim of this research is to determine and analyze the perceptions and behavior of upstream communities and governments about the function and role of water conservation and watershed in their behavior in the preservation of the watershed and its relationship with the current condition of the Ayung river. The study was conducted in the area upstream of Ayung river, which is in the Belok Sidan and Plaga Village, Petang, Badung, stake holder water users Ayung River such as PDAM, AMDK, rafting and farmers, as well as the government of Badung Regency that responsible for the management and conservation of Ayung River. Results of the study found that the public perception of the functions and benefits of watershed in the conservation of water resources classified in the category of high, but was followed by actions or attitudes in the medium category. There was no real relationship between perception and action, but the action affect current watershed conditions. The role and participation of stakeholders Ayung River water users were still relatively low in the preservation of the watershed, while the government's role classified as medium has not been done in an integrated among sectors and regions. From the results of this study it is recommended that the preservation of the Ayung river through various conservation action were integrated by involving communities upstream more active through the empowerment of local knowledge and improve their welfare. Government plays an important role in moving towards unity of this act.
