Reliable water-quality results begin before the sample reaches a laboratory. A clear objective, suitable containers, clean technique and complete field notes reduce avoidable uncertainty.
Before leaving for the site
Confirm what decisions the results need to support. That determines the parameters, sampling points, preservation method and laboratory coordination.
- ✓Prepare labelled containers and field forms
- ✓Check meter batteries, standards and calibration status
- ✓Confirm access, safety and weather conditions
- ✓Arrange cooling and transport where required
At the sampling point
Avoid disturbing sediment unless it is part of the objective. Record the exact location, time, water appearance, weather and any unusual activity nearby. Field observations often explain results that otherwise look surprising.
A repeatable method and complete field record are just as important as the sample itself.
