Maintaining the microbial quality in distribution systems and connected installations remains a challenge for the water supply companies all over the world, despite many years of research. This book identifies the main concerns and knowledge gaps related to regrowth and stimulates cooperation in future research. Microbial Growth in Drinking Water Supplies provides an overview of the regrowth issue in different countries and the water quality problems related to regrowth. The book assesses the causes of regrowth in drinking water and the prevention of regrowth by water treatment and distribution.

Biological wastewater treatment plants can be adversely affected by influent toxicity. The effects can range from poor clarifier biomass settling and elevated effluent BOD and ammonia levels to total plant kills. These problems could be minimized or eliminated if an effective method existed for continuously monitoring biological wastewater treatment plant influent for toxicity to the treatment plant microorganisms. Current influent screening methods have not been proven to be adequate for adaptation to continuous screening in the field. The primary reasons include the batch-wise nature of the assays and an inadequate correlation between the assays and plant performance. The goal of the research team was to create new bioluminescent biosensors from different types of bacteria found in biological wastewater treatment plants for the development of a multi-channel continuous monitoring system. A system built from multiple biosensors would make it possible to differentiate between potential influent toxicity effects to different classes of bacteria (such as nitrifying and heterotrophic bacteria). The research team found it unexpectedly challenging to apply common microbiological transformation methods for laboratory strains to the wastewater treatment plant strains. The research team generated six new bioluminescent bioreporters from bacteria that are typical constituents of activated sludge. Of particular significance is a bioreporter developed using a Hyphomicrobium sp., which is a slow growing bacterium known to be present in significant numbers in some activated sludge plants. Of the six generated, initial bioluminescence and toxicity screening indicated that one strain (a Pseudomonad) was a particularly promising candidate due to its ease of cultivation and high light production. Further toxicity testing, however, determined that the response of the strain to 48 organic compounds and 8 metals commonly found in wastewater was similar to that of a previously created strain, Shk1 (also a Pseudomonad). Further work is therefore needed in the generation of appropriate biosensors and test conditions for populations not represented by the new heterotrophic biosensor.

Surface water in European countries is monitored by permanent monitoring stations by public agencies in accordance with the Water Framework Directive (2000/60/EC) and national water legislation. In addition, water companies also monitor surface or ground water near the intake of the drinking water treatment plant, but also drinking and waste water. Part of the monitoring is performed by sensors; however, these are for basic physico-chemical parameters only, such as flow rate, turbidity, pH, temperature, conductivity and pressure. Apart from these parameters and as a function of specific requirements of each site, other parameters such as chlorine, fluoride, nitrate, particle count or total organic carbon can be also monitored online. During recent years, the increase in concerns that possible deliberate or accidental contaminations might reach the final consumer, has contributed to early warning systems becoming a good alternative for water managers.^An early warning system is an integrated system for online monitoring, collecting data, analysing, interpreting, and communicating monitored data, which can then be used to make decisions early enough to protect public health and the environment, and to minimise unnecessary concern and inconvenience to the public. To this end, new sensors are being placed into the market by small to medium-sized enterprises especially. Their main target is the detection of chemical and microbiological compounds, measuring single or a combination of parameters at the same time. In addition, due to the large amount of data collected, an easy to use and robust software is necessary to treat all data generated and provide clear information to the end-user.^The main drawbacks at the moment to effectively implement sensors are that, on one hand, there is a lack of standards for contamination testing in drinking water both in the EU and in USA and, on the other hand, there are poor links between available sensor technologies and water quality regulations.

The drinking water and wastewater industries are interested in developing a better understanding of sources of fecal contamination. Microbial source tracking (MST) offers the potential to apportion the contribution of various animal groups to this contamination. However, while there are many methods available there is no clear indication as to the most appropriate approach. There has been little systematic comparison of methods and only a few blind trials, and issues of reproducibility, accuracy, sensitivity, specificity, resolution, and robustness need to be addressed. There is confusion among potential end-users and some disagreement among scientists. Therefore, due to the uncertainty surrounding the most appropriate tools and applications of MST, a workshop of 45 experts representing water and wastewater utilities, academia, state and federal government agencies, medical institutions, and private laboratories was convened in San Antonio, Texas over a three-day period (February 16 – 18, 2005). The overall objective of the workshop was to identify the knowledge gaps and research needs for application of MST technologies by the wastewater and drinking water industries.
