CTG showcasing latest sensor technologies now available to rapidly detect microbiological contaminants.
Chelsea Technologies Group will be exhibiting & demonstrating their range of sensors to monitor water at the SWIG/RSC “Water & Health Workshop” on 31 January at University of the West of England, Bristol. Download Conference Agenda
Clean water and healthy food are seen as critical elements in ensuring a healthy nation, reducing the burden on the NHS. Our health can be put at risk if our water supplies become polluted or contaminated with bacteria, toxins or other chemicals and heavy metals.
In ensuring that the health of the nation is given priority, the Engineering and Physical Sciences Research Council (EPSRC) have identified a “Healthy Nation” as one of their Prosperity Outcomes of the strategy and delivery plan up to 2020. The EPSRC identifies that the development of new technologies materials will enhance our ability to predict, detect and treat disease. The application of new sensing technologies along with more traditional approaches and the application of connected systems can be used for the early detection of microbial pathogens and toxic chemicals preventing disease and ensuring the supply of clean water protecting the population from disease and contribute towards a healthy nation.
Justin Dunning will be showcasing the latest sensor technologies from the Chelsea Technologies Group that are now available to rapidly detect microbiological and chemical contaminants. He will be demonstrating the newly launched V-Lux Fluorometer which is configured to provide high quality in situ detection of either Algae, Aromatic Hydrocarbons or Tryptophan like fluorescence.
Chelsea Technologies Group have been working closely with the UWE & Bristol University to develop a fluorescence sensor for monitoring microbial processes of freshwater systems. This work addresses the urgent need for real-time in-situ monitoring of the microbial health and status of freshwater systems (surface and ground). One example of need is that, even within the UK, the increase in the frequency and intensity of rainfall is beginning to overstretch the capacity of existing infrastructure and sewage pollution in the country’s rivers and potentially in potable drinking water supplies is becoming a significant problem.
Dr James Sorensen, British Geological Survey (BGS) will be presenting on the “Applications of Fluorescent measurement in water monitoring”. The BGS developed a new way to measure faecal pollution in groundwater by using a Chelsea Technologies’ UviLux field sensor that measures the protein tryptophan. Dr Sorensen addressed the urgent need to screen drinking water for faecal contamination rapidly. His research involved multi-country assessment of tryptophan like florescence (TLF) as an indicator of faecal contamination. He found that a 1.3 ppb dissolved tryptophan threshold is effective to infer contamination. TLF is strongly correlated with thermotolerant coliform concentration.
