Tiivistelmä
Mätäjoki and Haaganpuro have been important urban streams in Helsinki in terms of their ecological and recreational values. These streams have been well known as a spawning place for trout. They have been home to many flora and fauna and carry a significance importance in the surrounding ecosystem.
The main aim of this thesis was to study the current condition of water quality in these streams in terms of physical and chemical parameters that include temperature, pH, electrical conductivity, dissolved oxygen, turbidity, total iron, total phosphorus and total nitrogen.
First, literature review was done to know about parameters and their effects on water quality. Parameters such as temperature, pH, electrical conductivity, dissolved oxygen were determined onsite and other parameters such as nutrients, iron and turbidity were determined in the Environmental Engineering Laboratory of Metropolia University of Applied Sciences. Five water samples of each streams were taken from five different locations of streams for the chemical analysis.
The result shows that the overall water quality of Mätäjoki and Haaganpuro is good. Concentration of dissolved oxygen was found to be very low in the first two sampling sites of Mätäjoki. Average concentration of total phosphorus in Mätäjoki is more than it was in 1995-1996 and 2004. Haaganpuro has better water quality than Mätäjoki.
