There is a great need to design and deploy chemical sensor systems for monitoring aquatic systems. Electrochemical sensing principles come to the environmental sciences from fields where they have previously been very successful, such as clinical diagnostics. The level of stability and reproducibility required in clinical monitoring, which is on the order of microvolt, is assured by careful temperature control and repetitive recalibration after sample measurement. This talk will explain the different electrochemical methodologies that are most attractive to electrochemical monitoring of aquatic systems, including our newest research direction, the development of calibration-free sensing concepts based on thin layer coulometry. Parallel efforts to use microelectrode integrated systems to detect trace level contaminants in natural waters and that has already found numerous applications for in situ monitoring will subsequently be summarized.
