Abstract
This study investigate the pollution levels (heavy metals) in Skurups city’s storm watersystem. Rain and runoff water (storm water) can be polluted and pose an environmental problem because it rarely gets purified on the way to our waterways. To find the various outlets where storm water reaches waterways, Skurups urban storm water systems were mapped. The city’s different businesses inside industrial areas were also mapped to see if pollution level could be correlated to industrial density. Six test locations were found throughout the city and two tests were taken on each site. Most of the outfalls exists on the city’s east side (4 outfalls on the east side and 1 outfall and 1 dam on the west side).

This study investigate the pollution levels (heavy metals) in Skurups city’s storm watersystem. Rain and runoff water (storm water) can be polluted and pose an environmental problem because it rarely gets purified on the way to our waterways. To find the various outlets where storm water reaches waterways, Skurups urban storm water systems were mapped. The city’s different businesses inside industrial areas were also mapped to see if pollution level could be correlated to industrial density. Six test locations were found throughout the city and two tests were taken on each site. Most of the outfalls exists on the city’s east side (4 outfalls on the east side and 1 outfall and 1 dam on the west side).

Metal pollution were found in each site in large variance to each other. Highest total metals in the storm water were found on the city’s east side although most businesses inside industrial zones were found on the west side. When the amount of metal pollution were compared to the health limits which different municipalities and organizations have set, the levels were not as high to cause any threat to health or the environment. However, the test were only taken during one day and just gives a small sample size of the situation. Data for rainfall amounts were also collected for the test day and a period past and showed that the only day with rain was the day before test day with 3.5 mm. This means that the metal level in Skurup storm water can be higher during a rain period. In summary, this study of metal concentrations in Skurup storm water is existing but relatively low and cannot be traced to any business. (Less)

Föroreningssituationen i Skurups dagvattensystem
Regn- och avrinnande vatten, så kallat dagvatten riskerar att förorena vattendrag, mark och grundvatten med dagens separerade avrinningssystem som oftast leder direkt till recipient utan behandling. Tungmetaller är några av dessa föroreningar som undersöktes i Skurups stads dagvattensystem. På alla undersökta platser kunde tungmetaller återfinnas men halterna låg under gränsvärdet för dagvatten och dricksvatten.

Provtagningen skedde endast under en dag och ger bara en ögonblicksbild av situationen. Nederbördsmängd påverkar tillexempel förorenings nivån, vilket var väldigt låg under provtagningsperioden enligt datan. För att se om stadens industrier hade någon påverkan på metallhalterna... (More)
Föroreningssituationen i Skurups dagvattensystem
Regn- och avrinnande vatten, så kallat dagvatten riskerar att förorena vattendrag, mark och grundvatten med dagens separerade avrinningssystem som oftast leder direkt till recipient utan behandling. Tungmetaller är några av dessa föroreningar som undersöktes i Skurups stads dagvattensystem. På alla undersökta platser kunde tungmetaller återfinnas men halterna låg under gränsvärdet för dagvatten och dricksvatten.

Provtagningen skedde endast under en dag och ger bara en ögonblicksbild av situationen. Nederbördsmängd påverkar tillexempel förorenings nivån, vilket var väldigt låg under provtagningsperioden enligt datan. För att se om stadens industrier hade någon påverkan på metallhalterna kartlades Skurups industrier. De högsta totala metallhalterna hittades på stadens östra sida även om den högsta industritätheten fastställdes till den västra sidan, vilket innebär att det inte gick att hitta något samband. Totalt blev det sex provplatser i staden och två prov togs på varje plats. De flesta av utloppen finns på stadens östra sida (4 utlopp på östra sidan och ett utlopp och en damm på den västra sidan).
