Environment monitoring Design and prototype develpment of an innovative technological platform based on wireless sensor networks for remote monitoring and sampling of surface waters Smart Water Sampling 16
Surface water monitoring A variety of technological challenges are faced in the development of water monitoring technologies: The list of regulated contaminants is growing thereby creating a greater incentive for automated monitoring. Water utilities are typically financially constrained and generally unable to invest in expensive monitoring systems, hence lower-cost, reliable systems are desirable. Furthermore, from a water security perspective, many measurement points are likely needed. This further substantiates the need for lowcost systems that are data-networked for maximum effectiveness. Additionally, for water security applications, timely measurements (on the order of tens of minutes) are needed in order to provide adequate time to respond to the phenomenon prior to the diffusion of contaminated water. False positive and negative measurement rates must be low for any monitoring technology to be useful to the water industry for the purposes of detect-to-warn. Consequently, monitor performance must be reliable and well understood. 17

Purposes of monitoring The in situ specific chemical and biological analyses are out of the scopes of monitoring! Ø To aggregate measurements of basic parameters in order to evidentiate the presence of polluting substances Ø To plan a space-time sampling sequence in order to estimate the dangerousness and capture samples for successive analysis Ø To alert the control center (detect to warn) Ø To pick up samples and bring them to the lab for specific analyses The system operates autonomously Human Intervention 20
