National Water Quality Instrumentation Service
•Who are we?
•What service do we offer?
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

•Temperature
•pH
•Dissolved Oxygen
•Ammonium(on request)
• 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
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
• Rapid Deployment – live data to the web within 5 minutes• Robust, self contained sensors for direct immersion
Esnet
• Rapid Deployment – kiosk installed within half a day • Pump system
Kiosk
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://

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

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
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
