The purpose of our study was to describe the dynamics of E. coli in the rivers of the Seine watershed. This watershed is characterized by a poor microbiological water quality due to an important population density, industrial activities and intensive agriculture. The main objectives of our study were to obtain field microbiological data describing the system and to understand the underlying mechanisms in order to build a model able to describe and predict the fate of the fecal bacteria at the scale of the whole watershed. This model was built in order to help management of microbiological water quality. <p>To be able to describe and modelize the fate of fecal bacteria at the scale of such a large and complex system, it was first necessary to identify and quantify the sources of contamination and to be able to describe the processes affecting these bacteria once discharged to the rivers. <p>The quantification of E. coli in the natural aquatic systems through the traditional culture-based techniques has been strongly questioned during the last years because they have a long response delay (24 to 48 h) and they do not take into account the viable but not culturable bacteria (VBNC) which nevertheless could represent a health thread. For this reason we developed in this study two alternative methods: the direct (without passing through a cultivation step) measurement of the â-D-glucuronidase activity and a fluorescent in situ hybridization with an E. coli specific probe coupled with a viability test. The first has the main advangate to give a very rapid evaluation of the E. coli content of the water while the second one was able to enumerate VBNC E. coli. <p>The study of the sources of contamination of the rivers revealed the predominance, in this anthropogenicised watershed, of the point sources (effluents from wastewater tretament plants). Diffuse sources soil leaching and surface runoff) may nevertheless be locally important and have also be quantified. The influence of the land use on these diffuse sources has been quantified demonstrating that soil leaching and surface runoff of grazed areas was mainly responsible of fecal contamination in rural areas.<p>The attachment of E .coli to particles in the river waters was studied as it can influence the fate of this kind of bacteria in the aquatic systems. A linear regression was found between the percentage of particle-associated E. coli and the SM content of the water. Settling velocities of particle-associated E. coli were determined. The mortality rate of E. coli was analysed following various perspectives: the river order, the attachment of E. coli to particles, the importance of the cultivability loss in the disappearance of these bacteria and the importance of protozoan grazing. The results confirmed the importance of grazing and showed that the abondance of free living E. coli bacteria decreased two times more rapidly than particle-associated E. coli. In the Seine river, we showed that the net loss of culturable E. coli was 1.5 time higher than the net loss of viable E. coli. Finally, no relationship was found between mortality rate and river order. <p>These results have been used to build two models CF-SENEQUE and CF-SiAM-3D which describe E. coli dynamics respectively for the whole Seine river watershed and for the Seine for the estuary. Comparisons model calcultaions with field data of fecal coliforms abundances showed that these models correctly simulated the longitudinal distribution of fecal colifoms in the main rivers of the Seine watershed and in the estuary. These models were used to test the impact on the microbiological water quality of various scenarii of wastewater management .<p> / Doctorat en sciences, Spécialisation biologie animale / info:eu-repo/semantics/nonPublished

Les technologies de captage, transport et stockage du CO2 ont pour finalité de capter le CO2 issu des industries afin de le stocker géologiquement et ainsi, réduire l impact de ces activités sur le réchauffement climatique. L Axe-Seine (Paris Le Havre) est un territoire très industrialisé et fortement émetteur de CO2. Dans ce territoire, les décideurs locaux envisagent l utilisation des technologies de CTSC afin de réduire les émissions de gaz à effet de serre. L objectif de notre recherche est de comprendre les futurs possibles de ces technologies dans l Axe-Seine. Dans cette perspective, cette thèse analyse tout d'abord le fonctionnement des technologies de CTSC dans une approche de sociologie des sciences et des techniques et les promesses technoscientifiques initiales associées à ce dispositif technique. Ensuite, cette recherche examine les dynamiques socio-spatiales de la vallée de la Seine concernant l'environnement. Enfin, cette thèse par une exploration des récits relatifs aux technologies de CTSC par les promoteurs de ce dispositif technique et des parties prenantes locales, identifie les hybridations potentielles entre ce dispositif technique et les dynamiques socio-spatiales de l'Axe-Seine. Ainsi est-il possible de décrire les futurs possibles des technologies dans l'Axe-Seine. Par ailleurs, dans cette recherche nous questionnons également la place des sciences sociales au côté des sciences de la vie et de la matière dans la dynamique de l'innovation technologique. / Carbon Capture and Storage enables industrial facilities to capture their CO2 emissions in order to geologically store it and then reduce their impact on global warming. The Seine Waterway Axis (from Paris to Le Havre) counts a lot of industrial facilities emitting huge quantities of CO2. From 2006 local stakeholders of this territory are willing to develop CCS to a commercial scale in order to reduce CO2 emissions.In our research we aim to understand potential futures of CCS technology in the Seine Waterway Axis. In this Phd thesis we first analyse initial technoscientific promises related to Carbon Capture and Storage in using Science and Technology Studies theoretical framework. Then we focus on the Seine Waterway Axis territorial dynamics regarding sustainable development. Finnaly, we focus on narratives related to Carbon Capture and Storage in the Seine Waterway Axis in order to identify hybridations between CCS implementations and territorial dynamics. These cross analysis will enable us to describe potential future of CCS establishment in the Seine Waterway Axis.

La dégradation de la qualité de l’eau de la Seine à Paris et dans sa banlieue depuis la deuxième moitié du XIXe siècle a fait l’objet de plusieurs études. Rares sont les études qui confrontent les perceptions de médecins, d’ingénieurs, d’hygiénistes ou d’administrateurs sur la qualité des eaux des rivières et l’évolution de leur état. Cette confrontation permet d’analyser sur la longue durée l’efficacité des réponses apportées pour améliorer la qualité, ce que nous avons réalisé ici pour la ville de Versailles et ses eaux. La première partie du mémoire décrit les perceptions de la qualité des eaux des rivières par des experts entre 1854 et 1964 sur la base de l’analyse de revues d’hygiène et d’assainissement urbain, montrant l’évolution des indicateurs de qualité et de la réglementation. Versailles a pour particularité d’être, au XIXe siècle, essentiellement alimentée par de l’eau de Seine grâce à la machine de Marly, par le biais d’un Service dépendant directement de l’Etat, conséquences de son passé royal. Mais la qualité de l’eau du fleuve se dégradant à cause des rejets des égouts de Paris, les différentes administrations, locales et nationales, doivent résoudre la question d’approvisionnement en eau alimentaire et recourent à l’aide d’experts pour s’assurer de sa qualité. Les analyses chimiques et bactériologiques effectuées sur les eaux conduisent à l’abandon de l’eau de la Seine en 1894 au profit des eaux de la nappe de Marly-Croissy. En même temps, Versailles rejetait ses eaux usées dans des cours d’eau à faible débit : le ru de Marivel et le ru de Gally. Epidémies et plaintes accompagnent la dégradation de leur état. Les nombreuses expertises menées témoignent de l’intérêt pour la qualité des eaux de surface et en même temps de l’absence de la volonté politique et des limites techniques pour l’améliorer, conduisant à leur sacrifice pendant plus de 100 ans. / The Seine River pollution both in Paris and its suburbs has been already the subject of several studies. Few studies compare perceptions that physicians, engineers, hygienists or managers might have of the quality of water resources, and the evolution of their state. This confrontation makes it possible to analyze over the long term the effectiveness of the responses made to improve quality. We have achieved this here for the city of Versailles and its waters. The first part of this work describes perceptions of river water quality by experts between 1854 and 1964 based on an analysis of hygiene and urban sanitation reviews, showing the evolution of quality indicators and of regulations. In the 19th century, Versailles has the peculiarity of being essentially fed by water from the Seine thanks to the Marly machine, through a service directly dependent on the State, consequences of its royal past. But as the water quality of the Seine River deteriorates because of the discharges from the Paris sewers, the various administrations, local and national, have to solve the question of water supply and asked for the help of experts to ensure its quality. The chemical and bacteriological analyzes carried out on waters lead to stopping the use of the Seine waters in 1894 in favor of the Marly-Croissy water table. At the same time, Versailles rejected its wastewater into two low-flowing streams: Marivel and Gally. Epidemics and complaints accompany the deterioration of their state. The numerous experiments carried out show the interest in the quality of surface water and at the same time the absence of the political will and the technical limits to improve it, leading to their sacrifice for more than 100 years.
