    Description / Table of Contents: Fractured bedrock aquifers have traditionally been regarded as low-productivity aquifers, with only limited relevance to regional groundwater resources. It is now being increasingly recognised that these complex bedrock aquifers can play an important role in catchment management and subsurface energy systems. At shallow to intermediate depth, fractured bedrock aquifers help to sustain surface water baseflows and groundwater dependent ecosystems, provide local groundwater supplies and impact on contaminant transfers on a catchment scale. At greater depths, understanding the properties and groundwater flow regimes of these complex aquifers can be crucial for the successful installation of subsurface energy and storage systems, such as deep geothermal or Aquifer Thermal Energy Storage systems and natural gas or CO2 storage facilities as well as the exploration of natural resources such as conventional/unconventional oil and gas. In many scenarios, a robust understanding of fractured bedrock aquifers is required to assess the nature and extent of connectivity between such engineered subsurface systems at depth and overlying receptors in the shallow subsurface.

    Description / Table of Contents: Zusammenfassung Es werden Methoden zur Mikrobestimmung von Chlor, Brom und Jod in fluorhaltigen organischen Substanzen beschrieben. Die Probe wird in einer Nickelbombe mit Natrium erhitzt. Das hierbei entstehende Chlorid wird mit Quecksilberoxycyanid nach einem modifizierten Verfahren titriert. Das Bromid wird nach Oxydation zu Bromat mit Natriumhypochlorit titriert. Das Jodid wird mit Brom zu Jodat oxydiert. Nach Zugabe von Jodid wird die sechsfache Jodmenge mit Thiosulfat bestimmt. Das Verfahren wurde für die gleichzeitige Bestimmung von Chlor, Brom und Jod in fluorhaltigen organischen Substanzen erweitert. Alle vier Halogene können somit unabhängig von ihrem gegenseitigen Verhältnis in einer Verbindung nebeneinander ineiner Einwaage bestimmt werden.
    Abstract: Résumé Des méthodes sont décrites pour le microdosage du chlore, du brome, de l'iode dans les composés organiques contenant du fluor. L'échantillon est chauffé avec du sodium dans une bombe de nickel et l'ion chlorhydrique produit est déterminé titrimétriquement par une méthode modifiée mettant en jeu l'emploi d'oxycyanure mercurique. Le brome est dosé volumétriquement après oxydation en bromate a ec l'hypochlorite de sodium. L'iode est déterminé également par une methode amplifiée après oxydation en iodate par le brome. La méthode a été étendue au dosage simultané du chlore, du brome, de l'iode quand ils sont présents dans des composés organiques contenant du fluor. Les 4 halogènes et toutes les combinaisons possibles d'halogènes peuvent être déterminées sur un seul composé après une simple fusion.
    Notes: Summary Methods are described for the micro determination of chlorine, bromine, and iodine in organic compounds containing fluorine. The sample is heated with sodium in a nickel bomb, and the chloride ion produced is determined titrimetrically by a modified procedure involving the use of mercuric oxycyanide. Bromide is determined titrimetrically after oxidation to bromate with sodium hypochlorite; iodide is also determined by an amplified procedure after oxidation to iodate with bromine. The method has been extended to the simultaneous determination of chlorine, bromine, and iodine when present in organic compounds containing fluorine. All four halogens, and all possible combinations of halogens, can be determined in one compound after a single fusion.

    Description / Table of Contents: Zusammenfassung Eine Methode zur Bestimmung von Schwefel in fluorhältigen organischen Verbindungen wird beschrieben. Nach Zerstörung der Substanz mit metallischem Natrium in einer Niekelbombe wird das Sulfid zu Sulfat oxydiert und dieses mit Barium gefällt. Der Niederschlag wird abfiltriert und in überschüssiger ammoniakalischer Äthylendiamintetraessigsäure gelöst. Der Überschuß wird mit einer Standardlösung von Magnesiumchlorid gegen Solochrom-Schwarz als Indikator zurücktitriert.
    Abstract: Résumé Description d'une méthode de dosage du soufre dans les composés organiques fluorés. Après décomposition de la prise d'essai par le sodium métallique en bombe de nickel, le sulfure formé est transformé en sulfate par oxydation et précipité sous forme de sulfate de baryum. Celui-ci est séparé par filtration et dissous dans un excès d'acide éthylènediaminetétraacétique ammoniacal de titre connu que l'on dose en retour à l'aide d'une solution étalon de chlorure de magnésium en présence de noir Solochrome comme indicateur.
    Notes: Summary A method for the determination of sulphur in organic compounds containing fluorine is described. After decomposing the compound with sodium metal in the nickel bomb, sulphide is oxidised to sulphate and precipitated as barium sulphate. The latter is filtered off, dissolved in an excess of standard ammoniacal E. D. T. A., which is then backtitrated with a standard solution of magnesium chloride using Solochrome Black as indicator.

    Description / Table of Contents: Zusammenfassung Die früher beschriebene Methode zur Mikrobestimmung von Fluor in organischen Verbindungen durch Schmelzen mit Alkalimetall in einer Nickelbombe und nachfolgende Titration mit Thoriumnitrat unter Verwendung eines Rücktitrationsverfahrens wurde weiter ausgearbeitet, um Störungen durch allenfalls anwesenden Phosphor oder Arsen zu vermeiden. Die vonOverman undGarrett angegebene Bindung von Phosphat und Arsenat durch Zusatz von festem Zinkcarbonat wurde zu einer quantitativen Entfernung dieser Ionen entwickelt. Schwierigkeiten bei der C-H-Bestimmung in fluor- und phosphorhältigen Verbindungen können durch Mischen der Probe mit Wolframoxyd umgangen werden.
    Abstract: Résumé Les perturbations apportées par la présence du phosphore et de l'arsenic ont conduit à modifier la méthode antérieurement décrite pour le microdosage du fluor dans les composés organiques et qui comportait une fusion en présence d'un métal alcalin dans une bombe de nickel suivie par un titrage par le nitrate de thorium d'après une technique de dosage en retour. La méthode deOverman etGarrett pour l'élimination des ions phosphate et arseniate par addition de carbonate de zinc solide a été adaptée à l'élimination quantitative de ces ions. Les difficultés rencontrées lors du dosage du carbone et de l'hydrogène dans les composés simultanément fluorés et phosphorés ont été surmontées par le mélange des prises d'essais avec de l'oxyde tungstique.
    Notes: Summary The method previously described for the micro-determination of fluorine in organic compounds by fusion with alkali metal in a nickel bomb followed by a thorium nitrate titration using a back-titration procedure, has been modified to meet the interferences caused by the presence of phosphorus and arsenic in the organic compound. The method ofOverman andGarrett for the removal of phosphate and arsenate ions by the addition of solid zinc carbonate was adapted for the quantitative removal of those ions. Difficulties in the determinations of carbon and hydrogen in fluoro-phosphorus compounds were overcome by mixing the samples with tungstic oxide.

    Description / Table of Contents: Zusammenfassung Bromierungsverfahren zur Bestimmung von Sulfid- und Disulfidgruppen in Einwaagen von nur etwa 50μg organischer Substanz wurden beschrieben. In manchen Fällen eignet sich die direkte Titration mit visueller Endpunktbestimmung, aber die Rücktitration ist allgemeiner anwendbar. Die Genauigkeit ist von der gleichen Größenordnung wie bei wesentlich größeren Einwaagen.
    Abstract: Résumé On décrit les méthodes de bromation pour le dosage des groupements sulfures et disulfures dans les échantillons organiques, sur environ 50μg de prise d'essai. Le titrage avec indication visuelle du point équivalent convient dans certains cas, mais une méthode avec titrage en retour se montre d'une application plus générale. La précision que l'on obtient est du même ordre de grandeur que pour le travail à échelle beaucoup plus grande.
    Notes: Summary Bromination methods are described for determination of sulphide and disulphide groups in organic samples weighing onlyca. 50μg. Direct titration with visual end-point indication is suitable in some cases, but a back-titration method is of more general application. The accuracy obtained is of the same order as on much larger scales of working.

    Description: The Dumfries Basin aquifer supports groundwater abstraction for public supply, agriculture and industry. Abstraction is concentrated in the western part of the basin, where falling groundwater levels and deteriorating water quality both reflect the effects of intense pumping. There are two bedrock units: a predominantly breccia-coarse sandstone sequence in the west, interfingering with a predominantly sandstone sequence in the NE and east. The basin is bounded by weakly permeable Lower Palaeozoic rocks, and is largely concealed by variable superficial deposits. Surface water flows onto the basin from the surrounding catchment via the Nith and the Lochar Water and their respective tributaries. Direct rainfall recharge occurs via superficial sands and gravels, especially in the north, and discharge is predominantly to the rivers in the central area rather than the sea. A picture is developing of two main aquifer types within the basin: the high-transmissivity western sector underlain by a fracture-flow system with younger water and active recharge and a high nitrate content, compared with the east where groundwater residence times are longer and the storage capacity is higher.

    Description: The Tōhoku earthquake and tsunami of March 11, 2011, resulted in unprecedented radioactivity releases from the Fukushima Dai-ichi nuclear power plants to the Northwest Pacific Ocean. Results are presented here from an international study of radionuclide contaminants in surface and subsurface waters, as well as in zooplankton and fish, off Japan in June 2011. A major finding is detection of Fukushima-derived 134Cs and 137Cs throughout waters 30–600 km offshore, with the highest activities associated with near-shore eddies and the Kuroshio Current acting as a southern boundary for transport. Fukushima-derived Cs isotopes were also detected in zooplankton and mesopelagic fish, and unique to this study we also find 110mAg in zooplankton. Vertical profiles are used to calculate a total inventory of ∼2 PBq 137Cs in an ocean area of 150,000 km2. Our results can only be understood in the context of our drifter data and an oceanographic model that shows rapid advection of contaminants further out in the Pacific. Importantly, our data are consistent with higher estimates of the magnitude of Fukushima fallout and direct releases [Stohl et al. (2011) Atmos Chem Phys Discuss 11:28319–28394; Bailly du Bois et al. (2011) J Environ Radioact, 10.1016/j.jenvrad.2011.11.015]. We address risks to public health and marine biota by showing that though Cs isotopes are elevated 10–1,000× over prior levels in waters off Japan, radiation risks due to these radionuclides are below those generally considered harmful to marine animals and human consumers, and even below those from naturally occurring radionuclides.
