  • Measuring Turbidity, TSS, and Water Clarity - Environmental

    Turbidity and Total Suspended Solids Measurement MethodsA Note on Turbidity, Turbidity Units and Unit ConversionsQuality StandardsMeasuring Turbidity Through Water Clarity MethodsHistorical Turbidity Measurement MethodMeasuring Turbidity with A Turbidity MeterMeasuring Turbidity with A Turbidity SensorTotal Suspended Solids Measurement MethodsMeasurement ComparisonCite This WorkTurbidity, as an optical property of water, is one of the more difficult parameters to measure. How murky or opaque water is can be a subjective measurement 1. Based on the measurement method, different units have been defined to standardize turbidity levels and allow comparisons. Today, there are three modern methods for measuring turbidity, and two for measuring total suspended solids. These methods have expanded the range and accuracy of turbidity measurements from basic object visibility tests and historical visual extinction methods 2. However, each method has its advantages and limitations. Turbidity is caused by particles and colored material in water. It can be measured relative to water clarity, or directly with a turbidity instrument such as a turbidimeter or turbidity sensor. Turbidity sensors may also be referred to as submersible turbidimeters 28. Water clarity methods involve a secchi disc or tube. They are often quick and inexpensive, but are only as accurate as the p...
