measurements use EPA 160.2, 2540D, or unknown methods.  For both the EPA 160.2 and the 2450D method, the well-mixed samples are filtered through a glass fiber filter and then dried to a constant weight at 103-105 degress Celsius.

Turbidity is measured by EPA method 180.1 (using Nephelometry)

Data format: HTML, excel, text, or zipped text file

Period of collection: Minimun and maximun dates available,
TSS: 1975-2007
Turbidity: 1967-2009

Parameter collection location:  100's of locations throughout the Delta and SF Bay for both TSS and turbidity
