When stormwater occurs near human activity the water gets polluted. The purity and composition vary widely depending on the types of activities in the area, the type of surface the water comes in contact with, precipitation and many more parameters. It has long been known that stormwater quality can affect both human health and the environment as stormwater is a major contributor to pollution of receiving waters.A human activity that has an impact on the environment in several different ways is traffic and stormwater is no exception. Airborne gases that react with precipitation, oil leaks and fuel systems that drops down on the ground, metals from brake linings and rubber particles from tire wear are some of the aspects you have to take into account when categorizing the relationship between traffic and polluted stormwater.In this project, stormwater samples from a parking lot in Halmstad, Sweden were collected and analyzed with an atomic spectrophotometer. The presence and relationship between copper, cadmium and zinc with different rainfall parameters have been studied.

In Europe, the central governments are the ones to coordinate the international standards and strategies regarding GPP; Green Public Procurement. However in Spain a GPP program was introduced late and only applied to the Central Government Institutions, (AGEA) (BOE nr. 027, 2008). These means that smaller administrations, such as, Autonomous Regions, Municipalities and Town Councils were not included in the program. The absence of a national program which excludes those governments made them introduce their own criteria for GPP, and the difference in criteria varies from one government to the other.

Klimatanpassning är ett aktuellt ämne i dagens stadsplanering och en utmaning för landskapsarkitekter och stadsplanerare. Klimatförändringarnas effekter är ökad nederbörd, stigande medeltemperatur och havsnivåer samt ett mer extremt klimat överlag. Detta får konsekvenser för ekosystem och städer, där den ökade nederbörden har direkt påverkan på dagvattensystemet. Som landskapsarkitekt har man möjlighet att ta vara på dagvattnet genom att utforma mångfunktionella och variationsrika miljöer. I det här arbetet har vi studerat den naturliga vattenbalansens processer och hur dessa kan användas för att återskapa vattenbalansen i den urbana miljön.
