  "field": "Environment",
  "definition": "1. The cloudy appearance of water caused by the presence of tiny particles. High levels of turbidity may interfere with proper water treatment and monitoring.\n\n2. The cloudy appearance of water caused by the presence of suspended and colloidal matter. Turbidity indicates the clarity of water and is an optical property of the water based on the amount of light reflected by suspended particles.\n\n3. A measure of opacity of a substance; the degree to which light is scattered or absorbed by a fluid.\n\n4. (ter-BID-it-tee) The cloudy appearance of water caused by the presence of suspended and colloidal matter. Technically, turbidity is an optical property of the water based on the amount of light reflected by suspended particles. In the waterworks field, a turbidity measurement is used to indicate the clarity of water. Turbidity cannot be directly equated to suspended solids because white particles reflect more light than dark-colored particles and many small particles will reflect more light than an equivalent large particle.\n\n5. The thickness, opaqueness or reduced clarity of water caused by the suspension of sediments. The turbidity of rivers and streams increases after a rainfall.\n\n6. Haziness in air caused by the presence of particles and pollutants.\n\n7. A cloudy condition in water due to suspended silt or organic matter.\n\n8. A measure of the cloudy condition in water due to suspended solids or organic matter.\n\n9. Haziness in air caused by particles, or cloudy condition in water caused by suspended silt or organic matter.\n\n10. Haziness in air caused by the presence of particles and pollutants. Federal Remediation Technologies Roundtable Glossary]\n\n11. Thickness, opaqueness or reduced clarity of water caused by the suspension of sediments. The turbidity of rivers and streams increases after a rainfall.\n\n12. The degree of clearness of a liquid or the lack of visual clarity of a liquid. It is defined by the measure of light scattering due to the presence of particles suspended in the liquid. Turbidity is similar to opacity for particles suspended in the gas phase.",
