Distribution of chlorides in the waters of the catchment of Macintyre Brook southern Queensland, and their effect on tobacco production

Abstract

The main source of chloride in the system was identified as Treverton Creek and its tributaries, waters here containing in excess of 80 p.p.m. chloride. A perched water table of inferior quality probably feeds into Macintyre Brook near the tobacco-growing area, increasing chloride content to an average of 55 p.p.m. Springs of low-quality water also affect the chloride content of the main stream in places. The practical implications of a water supply containing more than 40 p.p.m. chloride for land use in the area are discussed.
