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 runoff from a development site (TSS).

Take a water sample from the designated monitoring point — where safe and practical, collect from flowing water rather than stagnant areas. Slowly pour the sample into the turbidity tube.
