Suspended Solids Concentration (mg-l 1 ) 



Figure 2-3. Plot illustrating the results of the laboratory calibration to determine the 



correlation between relative turbidity (in NTUs) measured by the Seapoint 

 turbidity sensor versus suspended solids concentrations (in mg-l" 1 ) 

 determined by laboratory procedures. A linear relationship was used to 

 convert from NTUs to mg-l"' for all monitoring data.
