Abstract (Swedish)
EU:s deponeringsdirektiv har medfört ökade krav på deponier. Mängden deponerat organiskt material har

begränsats kraftigt och deponiernas inre skall nu vara så torrt som möjligt. Konsekvenserna av detta är ännu inte

helt kända. Fläskebodeponin, den deponi som varit i drift längst av de få svenska deponier som är konstruerade

enligt direktivet, har här fungerat som ett exempel på framtidens deponier. Dess lakvatten har studerats med

hjälp av de multivariata analysmetoderna principalkomponentsanalys (PCA) och kanonisk korrelationsanalys

(CCA) samt med den geokemiska beräkningsmodellen PHREEQC. Flera intressanta samband hittades och

resultaten visar tydligt att multivariata metoder... (More)

resultaten visar tydligt att multivariata metoder har en stor potential när det gäller att hantera lakvattendata,

inte minst på grund av deras förmåga att vaska fram den mest relevanta informationen. I kombination med den

geokemiska modellen kan de leda till ökad förståelse av processer som styr lakvattenkemin. Nästa steg i studien

blir att jämföra Fläskebos lakvatten med vatten från äldre deponier för att med hjälp av multivariata metoder

hitta intressanta skillnader och likheter. (Less)
Abstract
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 example of future landfills. Its leachate has been studied with multivariate techniques (principal

component analysis and canonical correlation analysis) and with the geochemical model PHREEQC. Several

interesting correlations were found and the results clearly show that multivariate statistics can be of great use

when studying landfill... (More)

interesting correlations were found and the results clearly show that multivariate statistics can be of great use

when studying landfill leachate. Their ability to extract the most important information is one thing that can

be very useful. Combined with geochemical models they can provide an increased understanding of processes

governing leachate quality. The next part of the study will be to use multivariate statistics to compare Fläskebo’s

leachate with that from older landfills to find interesting differences and similarities. (Less)
