Geographical Trends in Water Chemistry of Wetlands in Western Cape South Africa

Conductivity and pH measurements were made at 73 wetlands in the south-western Cape Province. The concentrations of the major cations and anions were determined in samples from 42 of these wetlands. Total dissolved salts (TDS) concentrations ranged from below 20 mg/L to more than 200 000 mg/L, and pH values as low as 4 and greater than 10 were recorded in some wetlands. Despite these extremes, the ionic ratios showed regional trends: Na+ and Cl are the dominant ions in wetlands near the coast, and HCO3 is the dominant anion in inland wetlands
