ADVANCED ENVIRONMENTAL BIOCHEMICAL SENSOR FOR WATER MONITORING

The protection of water resources and the secure delivery of clean water to consumers are important tasks for humans in the future. Therefore, it is necessary to have novel analytical systems to control water quality. Here we give a review on the performance of the AWACSS (Automated Water Analyser Computer Supported System) biosensor and describe the results obtained during a field test and for a validation with drinking water. The system was developed during a research project (EVK1-CT-2000-00045) supported by the European Commission under the Fifth Framework Programme and contributes to the implementation of the Key Action "Sustainable Management and Quality of Water" within the Energy, Environment and Sustainable Development. The system is based on immuno- chemical technology and can measure a variety of small organic pollutants in water at the low nanogram per liter level in a single few-minutes analysis without the need of any pre-concentration or pre-treatment steps. Furthermore, this instrument is equipped with a software package for remote control and web-based networking between the measurement and control stations, global management, trend analysis, and early-warning applications. The AWACSS biosensor is a fully automated, sensitive, cost-effective, and easy-to-use analytical system for the continuous monitoring of surface, ground and drinking water.
