A turbidity tube is a simple field tool used to check how cloudy or turbid the water is (NTU), which can help identify silt sediment volume from a development site (TSS) — part of surface water monitoring commitment on construction sites. Watch the short video below, or follow the steps.
Bring the turbidity tube to your designated surface-water monitoring point.
Slowly fill the tube with your water sample until the cross marker at the base disappears from view.
The scale reading at that fill level is your turbidity result — record it in the site’s monitoring log.
Empty the sample and rinse the tube with clean water so it’s ready for the next reading.
A clear tube used to visually assess the turbidity, or cloudiness, of a water sample. The sample is viewed against a marker, and the result read from the tube's scale.

A turbidity tube is a field-monitoring method and can be used in conjunction with laboratory analysis or other specified monitoring methods. Always follow the monitoring methodology and requirements applicable to your individual project.
Check the tube regularly against a clean light source. Scratches, cloudiness or yellowing on the plastic scatter light and can make readings look worse than the water actually is. If it won’t polish clean, it’s time to retire it — request a quote for a replacement.
