Understanding Suspended Sediments, Solids, and Turbidity
Webinar Overview
Different standard methods of turbidity field measurement are recommended based on the desired outcome and program protocol requirements. In this webinar, Larry Freeman walks through the definition of these methods, defines which indicators should be monitored based on a specific application, and discusses the confusion between TSS, TDS, and SSC.
After attending this webinar, you will understand:
- The difference between turbidity, total dissolved solids (TDS), total suspended solids (TSS) and suspended sediment concentrations (SSC), and why they’re often confused.
- Common measurement methods and when to use them (ASTM, EPA etc.)
- Surrogate measurement methods.
- The state of turbidity sensor technology.
This webinar will cover content relevant to the following industries:
- Government agencies with responsibilities related to:
- Regulatory compliance and program oversight
- Watershed management
- Fishery services
- Climate change research
- Cooperative monitoring agencies
- Boating and waterways
- Dredging
- Source water protection
- Wastewater/Drinking water treatment
- Environmental protection
- Watershed management
- Research organizations
- Lake and Reservoir management
- Engineering & consulting services

Larry Freeman is the owner of Freeman Hydrologic Data Services. He retired from the USGS after 36 years prior to establishing his consulting firm in May 2015. The last 17 years he served as the Field Office Chief for the Salinas, then Marina, and finally the Santa Cruz offices in California. He holds a Level 3 Hydrologic Technician Water Quality Certification (Sediment focus) from the American Institute of Hydrology. He was recently appointed to serve on the Soquel Creek Water District Supplemental Water Supply Committee. He has extensive experience with data program management as well as technical expertise with instrumentation, field data collection protocols, and records computation of streamflow, fluvial sediment transport, and ground-water-level monitoring. He has several publications in these disciplines and was a regular instructor for several USGS training classes for many years.
