A study on environmental conditions of a large number of landfills, in which waste storage has occurred in '70-'80s, has begun on behalf of the Province of Vicenza. The main purpose of the work, resumed on this paper, is to draw up an inquire priority list and, subsequently, to design monitoring networks in order to test groundwater chemical conditions. Based on the results, a site-specific risk analysis for the groundwater shall be performed. The identified sites are a total of 43, distributed throughout the Province of Vicenza. Site locations are shown in the table enclosed to this paper.

Closing down Pääsküla landfill. Post-closedown environmental monitoring and maintenance of the landfill
© NMC Ltd. (10/2010)
Pääsküla landfill is the largest municipal waste landfill in Estonia which was established 1972 and closed 2003. The landfill was closed down during 2003-2006 within ISPA (The Instrument for Structural Policies for Pre-accession) project. At the moment of closing down its volume was 4,5 million cubic metres, relative height 29 metres and its area nearly 30 hectares. The total cost of the project was 11 225 009 EUR (175 633 228 EEK) including V.A.T 18 per cent. Objectives of the projects were to minimize the environmental impacts in a long perspective against main hazards as contamination of groundwater and surface water, landfill gas leakage, health hazards to neighbourhood dwellings and nuisance like smell, fly trash, gulls and other birds and rodents.
METAL SPECIATION IN NINE FRENCH LANDFILL LEACHATES
© IWWG International Waste Working Group (10/2007)
Several heavy metals or metalloids, that may be present in landfill leachates, are considered as priority pollutants for groundwater resources (for example lead, cadmium, nickel; OJEC, 2001). While the fate and transport of such elements are largely influenced by chemical speciation reactions, landfill risk assessments generally adopt a simplified “Kd” approach which assumes steady-state liquid-solid partition between the liquid and solid phases. Such simplification may result in a severe overestimation of long-term environmental or health impact. Speciation reactions such as precipitation or co-precipitation participate in the natural attenuation of landfill leachate and help explain why heavy metals are rarely detected in groundwater at significant distances from landfills (Christensen et al., 2001).
Partizipation betroffener Akteursgruppen zur Minderung der Nitratbelastung des Grundwassers
© Springer Vieweg | Springer Fachmedien Wiesbaden GmbH (10/2020)
Die Nitratwerte im deutschen Grundwasser sind vielerorts seit über 20 Jahren erhöht. Die EU-Kommission beurteilte entsprechende Gesetzesnovellen der vergangenen Jahre mehrfach als unzureichend. Vorgestellt werden Untersuchungsergebnisse dazu, unter welchen Voraussetzungen kleine partizipative Gremien lokal zu einer Einhaltung der Nitratgrenzwerte in ihrer jeweiligen Region beitragen können.
Nitratentwicklung im Grundwasser gegen den Trend

Steigende Nitratwerte im Grundwasser müssen nicht sein. Mit Etablierung einer seit 1996 in Hessen möglichen Wasserschutzgebietskooperation in Verbindung mit einer Wasserschutzgebietsausweisung sind auch in landwirtschaftlichen Einzugsgebieten sinkende Nitratwerte im Grundwasser zu erreichen. Erfolge in Nordhessen.
Fehlentwicklungen verhindern

Das wirtschaftliche Wachstum und der Verbrauch von begrenzt verfügbaren Rohstoffen
müssen voneinander entkoppelt werden. Hierzu können die Vermeidung von
Abfällen und die Gewinnung von sekundären Rohstoffen aus verwertbaren Abfällen einen wichtigen Beitrag leisten.
