Water Quality Monitoring

We specialise in the supply, installation and operation of continuous water quality monitoring sites, typically covering parameters such as temperature, conductivity, pH, and dissolved oxygen (DO).

These are usually supplemented by either automatic volumetric sampling triggered using event specific thresholds, and/or spot samples using either a hand-held sonde or bottled samples.

For full-suite laboratory analysis of bottled samples we work with local specialist laboratories for the most efficient and cost-effective delivery.

Our services

We can monitor and provide data on a range of water quality factors, including:

• Temperature
• Conductivity
• pH
• Salinity
• Turbidity
• Dissolved oxygen
• Biochemical oxygen demand (BOD)
• Chemical pollutants (ammonia, nitrates, etc)

Our experience and expertise

Our recent field data collection has included major studies for UK water companies to assess the impact of abstractions on the aquatic ecology within watercourses, through a programme of spot samples and installation of telemetered sondes at important sites.

Other recent projects include:

• Water quality monitoring for construction sites to ensure consent compliance and prevent enforcement or prosecution
• Continuous turbidity monitoring for a major UK water supply company to enable them to better understand the impact of their activities on river water quality
• Landfill leachate level monitoring telemetry system for waste-disposal operators
• Discharge consent compliance monitoring for an international airport
• Warning system for high turbidity due to tunnelling operations near to public water supply wells in chalk groundwater
• Purge sampling of boreholes to calibrate automatic water quality monitors
• EA R&D study to investigate the feasibility of using Acoustic Doppler Current Profiler (ADCP) technology for the measurement of sediment flux

Our data management capabilities

We are also able to offer specialist data management services through our unique access to Aquarius Time-Series software and via our own Hydro-Logic® Timeview telemetry platform, including remote access to your real-time data.
