Various measurements utilizing soils, plants, precipitation and free water surfaces indicate that approximately 7 to 9 kg/ha of sulphate S was deposited annually within an area of 4600 km('2). This area contained or had adjacent to its boundaries 10 S emission sources for which the provincial government had established a combined allowable daily emission of approximately 330 tonne S. At distance of 40 or more km from the emission sources the annual deposition rate had declined to 4 to 6 kg/ha.
