The aim of the study is to assess boron content of Emet, Orhaneli and Mustafakemalpa?a streams in Susurluk basin. Mustafakemalpa?a stream consist of a blend of Orhaneli and Emet streams and ends to a very important ramsar site, Lake Uluabat. The water quality data were obtained from Turkish General Directorate of Electrical Power Recourses Survey and Development Administration (EIE). Samples were taken between 1995-2008 for Emet stream, 1984-2008 for Mustafakemalpa?a and 2005-2008 for Lake Uluabat. The water samples for Orhaneli stream were taken from two different locations and the sampling years were 1992-2008 for one location, 2005-2008 for other location. The mean boron contents of those two locations on Orhaneli stream were measured 0.13 and 0.18 ppm and found safe as irrigation water. Boron content in Emet stream increased dramatically after 2004. While mean boron content was 4.68 ppm before 2004, it increased up to 28.24 ppm after 2004. This data reveals that while, earlier than 2004 the stream water should not have been used as irrigation water, later than 2004, it became even more dangerous to habitat and perhaps to human life. In the irrigation seasons (between March and September), mean boron content was 0.90 ppm until 2004 and then increased up to 3.22 ppm after 2004. Pollution in Emet stream moved into Mustafakemalpasa stream and made it unusable as irrigation water. Since there was no data earlier than 2004 for The Lake Uluabat, it was not possible to reveal the change in boron content. On the other hand, data between 2005 and 2008 shows that especially in irrigation season (March-September) mean boron content was 5.60 ppm, which this makes the lake unsuitable for irrigation.
