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

• 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
![Page 6: CaBA Lancaster 01 June Jones Environment Agency](https://reader031.vdocuments.us/reader031/viewer/2022030303/587c3fd91a28ab5a1d8b60fd/html5/thumbnails/6.jpg)
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

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
