01/What problem do we address
We survey in the field and record environmental change
We survey rivers and the sea, from water quality, sediment and biota to subsea electromagnetic fields.

What we do
Seasonal water quality and sediment monitoring
Rivers · Lakes
Water quality and sediment surveys of rivers and lakes to assess the state of contamination and changes over time
- River water quality sampling
- What we survey
- Multi-matrix sampling
- Sampling of river water, lake water and sediment, and by inflow pathway
- Repeated monitoring
- Repeat surveys at the same stations, comparing change across seasons and before and after rainfall
- Standards and trend assessment
- Interpretation of contamination levels against the criteria for each matrix, and of time-series change
- Field surveys
- Safety check before sampling
- River water sampling
- Drainage channel sampling
- Inflow and drainage facility survey
- Survey procedure
- From survey preparation to field sampling
- Review of existing data
- Review of past survey data, research findings and local conditions
- Station selection
- Selection of survey stations using public data and previous survey results
- Field survey planning
- Advance check of stations, sampling parameters, schedule and site conditions
- Field survey and sampling
- Field measurement, sampling and survey of the surroundings after an on-site safety check
- Analysis and assessment
- From field measurement to integrated interpretation
- Field and water quality analysis
- Analysis of field parameters such as water temperature, pH, DO and EC, and of water pollutants
- Sediment analysis
- Analysis of sediment contamination parameters such as organic matter and metals
- Integrated assessment
- Comparison with past survey results to assess the spatial and temporal state of contamination and its trends
