- 1. National Water Quality Instrumentation Service (NWQIS)
- 2. National Water Quality Instrumentation Service •Who are we? •What service do we offer?
- 3. National Water Quality Instrumentation Service •Previously a regional team •New national team created in 2011, sits within the National Laboratory Service •Provide hand held meters and mutli-sensor sondes to area teams, DEFRA partners and external organisations •Equipment used in WFD investigations, water quality monitoring, incident response and research
- 4. National Water Quality Instrumentation Service Hand Held meters Pro Plus Meter • Specific Conductivity/Salinity •Temperature •pH •Dissolved Oxygen •Ammonium(on request)
- 5. • Rugged IP67 PELI enclosure • Twin batteries with quick release • Lightweight • Shockproof • Multiple connectors for sensors • External Power Options • Simple User Operation • GPRS real time comms Environmental Sensor Network - ESNET
- 6. Using the ESNET a wide range of parameters can be measured: • Flow • Temperature • Ammonium • Conductivity • Dissolved Oxygen • PH • Turbidity • Chlorophyll And interface to control equipment: • Autosampler (for analysis of nutrients, metals and pesticides) This can be supplemented by other measurements: • Rainfall • Level / Flow • Meteorological Data
- 7. • Rapid Deployment – live data to the web within 5 minutes • Robust, self contained sensors for direct immersion Esnet
- 8. • Rapid Deployment – kiosk installed within half a day • Pump system Kiosk
- 9. Web display via Meteor Data Communications (MDC) website • Secure password access • Intuitive controls • Clear graph or table view •View on PC / smart phone / tablet • Multiple user access • Open data access options- •http://www.telemetry- data.com/open?profile=Leeopen
- 10. Working in Partnership •Barton Brook WFD waterbody failing for phosphate •Collaborative project with Blackpool and Fylde College •Allowed a greater area to be covered and additional information gathered •Data analysed by students and fed back to area staff
- 11. Data from Barton Brook Upstream Downstream
- 12. The benefits of using Volunteers: • Security of equipment •Maintenance of equipment • Can monitor the data in real time, receive alarms. Can be on site quicker if an event occurs •Larger area can be covered •Data fed back to improve knowledge/understanding of water quality which feeds into WFD basin planning
- 13. The benefits of real time, high resolution data: • More detailed view of events • Transient events are captured • Earlier warning of issues • Greater understanding of the relationships between the measurement parameters • Clear linkage of the timing between events and the effect of one parameter upon another • Ability to pinpoint events very clearly by time and geography

Editor's Notes
- Monitoring for a snap shot of data, useful when doing walk over surveys
- Obviously we can’t be everywhere all the time, so this piece of equipment allows us to get a better look at what is happening over a longer period. It helps to have eyes on the ground to check that the equipment is still in place and working properly. Volunteers can help with security, cleaning equipment if required-Hogsmill
- Data to any web enabled device Can create bespoke graphs, interactive weblinks to view sites geographically Training on how to interpret data
- This study will potentially help the area team address this WFD failure and is therefore extremely important. Students will analyse data on a daily basis and will plan their additional field samples / observations accordingly.
