The revised EU Bathing Waters Directive of 2015 now requires maintaining low levels of E Coli and Enterococci within Bathing Waters. Authorities responsible for these bathing are now using the CTG BACTI-Wader & BACTI-Wader Pro systems. These are low cost & easily deployed, & can be sited close to bathing beaches and within nearby estuaries and rivers to provide early notification of potential non-compliance (e.g. resulting from agricultural run-off following high rainfall or CSO events). Offering un-paralleled sensitivity, the BACTI-Wader sensors can detect small changes in bacteria concentrations, offering the potential of setting alarms to warn when acceptable contamination levels are exceeded. These systems allow surveyors and regulators to assess real-time, in situ levels of bacteria in water systems. This is achieved by detecting UV Tryptophan fluorescence, which has been shown to correlate with bacterial levels.
