Natural waters of relatively low ionic strength are especially sensitive to contamination. There is particular interest in changes in the acid status of such waters. Studies of acidification and any consequent changes in the chemistry of low ionic strength waters rely heavily on the accurate determination of pH value. This measurement poses problems which might be difficult to detect and overcome unless appropriate Analytical Quality Control (AQC) procedures are implemented. The aim of this work was to test the suitability of several samples for use in routine AQC for pH determination in low ionic strength waters. Four solutions, two dilute mineral acids and two low ionic strength buffer solutions, were tested.
