Abstract [en]

The purpose of this project was to optimize the filtration process when analyzing ground water for risk assessment. Particulate (>0.45 μm), colloidal (0.45 μm<diam.<0.01 μm) and dissolved metal species were studied using different filtration methods: flow filtration in the field using peristaltic pump and in-line filter; replaceable filters and syringe filter in the field; replaceable filters and syringe filter in a laboratory environment.

Studies where metal concentrations in the filtrate are measured as a function of the amount of material enriched in the filter was carried out. MP-AES were used for analyzing the metals in controlled systems and the reference method was done with ICP-MS. The project was done on the behalf of Structor and evaluation were also made between the sampling methods that Structor has undertaken and the methods that was examined in this report.

The results were evaluated by comparison of guideline values set by the World health organization, WHO on drinking water and the regulation and status classification and environmental quality values of ground water recommended by the Swedish Geological Survey, SGU. Produced data was assessed by conventional statistics.
