This chapter explores the application of emerging technologies for waterborne pathogen detection from a market perspective. The water market, particularly in terms of monitoring, is heavily driven by regulation and regulatory compliance. Adoption of new technologies for the detection of pathogens can be challenging within this framework. This chapter will first describe the application of water safety plans (WSPs)and the water safety frameworks (WSF) in various countries, to set the background in which water monitoring is performed across the globe. There will be a particular focus on the situation in the UK as an in-depth case study. The chapter will also identify those pathogens which are currently of most concern to the market, providing a perspective from a public health point of view as well as the market view of existing technologies. Finally, the chapter will conclude by discussing future trends and the challenges of bringing new technologies to market in the water monitoring sector
