Finnish Well Water Quality in Rural Areas Surrounded by Agricultural Activity
In this study 136 wells (88 shallow and 48 deep) from rural areas in Western and Eastern Finland were analyzed during the years 2005 and 2006. The objectives of this study were to assess the general quality of the wells based on conventional indicators and novel organic matter analyses with the aid of High Performance […]
Intensiva regn i Malmö / Intensive storms in Malmö
Short-term intensive storms of duration up to an hour the years 1980–2007 from rain gauges in Malmö have been analyzed to find intensities of long return periods. Non-dependent observations from different stations have been combined into a series to which probability functions have been adjusted. The extreme events have been investigated individually. The reliability of […]
Kvalitet i nya deponiers lakvatten – resultat från Renovas deponi Fläskebo / Quality of leachate from new landfills – results from Renova’s landfill Fläskebo
The European landfill directive increases demands on landfills. The amount of organic matter being landfilled is restricted and landfills should be as dry as possible. The consequences of these changes are not yet fully understood. In this study the first landfill in Sweden to be constructed according to the directive, Fläskebo, has served as an […]
Cost effectiveness and fairness of the Helcom Baltic Sea Action Plan against eutrophication / Kostnadseffektivitet och rättvisa i Helcoms aktionsplan för minskad övergödning i Östersjön
This paper evaluates the Baltic Sea Action Plan (BSAP) proposed by Helcom (Helsinki Commission) to combat eutrophication in the Baltic Sea with respect to cost effectiveness and fairness. The background is the documented needs of both these factors for truthful implementation of international agreements, such as the ministerial adoption of BSAP in autumn 2007. The […]
Variabilities and uncertainties in important coastal water variables
The focus of this work is on general patterns in uncertainty as well as temporal and spatial variability in key water variables in coastal science and management. These patterns are essential since they regulate how many samples must be taken to get reliable mean or median values characterising coastal water quality and which variables are […]
Supercritical oxidation of Water work sludge From Ringsjöverket
This paper presents how super critical water oxidation (SCWO) performs on the iron rich sludge from the drinking water treatment plant Ringsjöverket. The pilot-test shows that the SCWO-technique is capable of treating the sludge from Ringsjöverket. During the pilot- test all organic material were oxidized while the rest precipitated as ferric oxide crystals. Chromium and […]
Brunnsvatten och grönsaker från sura respektive basiska områden – vilka skillnader i mineralinnehåll föreligger? / Well waters and vegetables from acid areas and an alkaline region –what differences are there in mineral content?
Well waters and women’s hair from acid, and an alkaline area, were analysed on about 40 elements and ions in 1997. The alkaline waters and hair had significantly higher concentrations of e.g. Ca, Mo and Se. In april 2006, 30 women from the acid area, northern Scania, southern Småland and southern Älvsborg counties, and 30 […]
Why the Oxidation Ditch disappeared in Sweden? / Varför försvann Ringkanalerna i Sverige?
The Oxidation Ditch has played a very important role as a foregoer for a number of low load activated sludge systems in the water industry. Today different models are found around the world. The ditch system developed in the late 1950’s originated in the Netherlands. Early Swedish research and development work took place in the […]
