“…A biomonitor is useful only if it supports sound decision‐making. Biomonitor alarms are typically used in conjunction with available chemical monitoring data to trigger further analysis (Gunatilaka & Diehl, 2000; Kramer & Foekema, 2000). As with any early warning system in general (Gullick et al, 2003), a response plan must be put in place before a biomonitor alarm occurs.…”

“…Although federal and state agencies do not mandate that water utilities monitor raw water in real time, many water suppliers have adopted a proactive approach (Gullick et al, 2003; Schreppel, 2003; Grayman et al, 2001; Stoks & Penders, 2001). The desire for rapid identification of adverse water quality changes is evident in the development of early warning systems for both individual water utilities and regional source water protection (Gullick et al, 2004; Grayman et al, 2001; Gunati‐laka & Diehl, 2000; ILSI, 1999).…”

Automated biomonitoring systems provide continuous, real-time monitoring of changes in water quality and can rapidly identify toxicity associated with a wide range of chemical contaminants and increase public confidence in drinking water quality. Although widespread in Europe, biomonitor use is rare in the United States. Using case studies of a biomonitor that continuously monitors fish ventilatory patterns, this article illustrates how biomonitors can contribute to an early warning monitoring system for source and finished water protection.The case studies provide a context for a discussion of considerations important for biomonitor implementation, including toxicant responsiveness, event confirmation, implementation of biomonitors in a decision-making process, and cost. Recommendations are also provided for biomonitor use at raw water intake and distribution systems.

“…For real-time monitoring, sensor-based methods are widely used by detecting changes in the physicochemical factors such as pH, dissolved oxygen demand, and biochemical oxygen demand. However, use of devices for such methods requires expensive analysis and manpower (Gunatilaka, 2001).…”

In this paper, based on the behavior of Caenorhabditis elegans (C. elegans) in response to a toxic substance, we propose a novel biological monitoring method for the detection of water contamination. Both before and after the introduction of formaldehyde into the water at the concentration of 0.1 ppm, the swimming activities of C. elegans are continuously recorded by a charge coupled device camera at the rate of four frames per second. The behavior in each of the image frames is characterized by the branch length similarity (BLS) entropy profile. The shapes quantified by the BLS entropy profiles are classified into seven shape patterns via the self-organizing map combined with the k-means clustering algorithm. Subsequently, a monitoring scheme composed of two hidden Markov models decides the water quality based on the sequence of shape patterns over a certain observation time. The performance of the proposed method is generally affected by the observation interval; yet, experimental results show an accuracy of about 83% for an observation time of five minutes. It is also observed that, by taking the distribution of individual decisions into account, the accuracy of the proposed method can be improved up to 93% and the false negative rate can be reduced to 10%.

“…Due to the randomised occurrence of accidental spills the only way to quickly detect hazardous situations is to perform continuous monitoring of surface water quality. General questions of monitoring and early warning are widely discussed by Kramer and Botterweg (1991), Baldwin and Kramer (1994), Helmer and Hespanhol (1997), Gunatilaka and Diehl (2000), Schneider (2001), Grayman et al (2001) and Gunatilaka and Dreher (2003).…”

Possible way to substantial improvement of early warning system in the International Odra (Oder) River Basin

Water ecosystems are threatened by accidental spills of pollution. Rapidity and trueness of information gathering the biological impact of accidental pollution is crucial for the efficiency of the minimisation of possible deterioration of ecosystems and for success in detecting the source of pollution. Due to the randomised occurrence of accidental spills the only way to quickly detect hazardous situations is to perform continuous monitoring of surface water quality. The current situation in the field of early warning in the International Odra (Oder) River basin is not satisfactory. The actual number of monitoring stations and list of routinely continuously monitored parameters are not able to meet the needs of sensitive and rapid detection of biological impact of accidental pollution spills. An effort to change this unfavourable situation was the reason for the offer survey, selection and a model operation of a commercially produced biological monitoring device. This apparatus was located on the border-line profile on the territory of the Czech Republic and represented the first and only one tool of continual biological monitoring of surface water quality in the International Odra (Oder) River Basin. The selected apparatus was the Daphnia Toximeter produced by the firm bbe Moldaenke (Kiel, Germany). This device exploited for rapid detection of changes of biological quality of surface water evaluation of behavioural response of monitoring organisms-daphnids. Five years of model operation proved its suitability for early warning purposes. The apparatus was reliable in function and sensitive enough to detect the deterioration of the biological quality of the river water. The given examples document its applicability not only for detection of accidental spills but also of illegal emissions of pollution, which are very often toxic.
