Specific conductance (SC) is widely used as a measure of mineral salt concentration and a variety of models have been employed which relate SC to total dissolved solids (TDS) and individual ionic concentrations. This paper attempts to evaluate several models and highlights two major problems associated with them from analysis of water samples collected from two small catchments in East Devon and North Warwickshire. First, the presence of dissolved organic material, at the levels encountered in soil solutions, may seriously affect the SC/TDS relationship and will often be an undetected component of dissolved load. Secondly, the low pH of some water samples is shown to affect those models which calculate SC on the basis of individual ionic concentrations. This results from high H+ ion levels and associated increased solubility of other ions, such as Fe3+, Al3+ and Mn2+ which are not normally determined in water quality studies. |
