Project Summary

Deposition of ambient particulate matter (PM) has been implicated as a major source of nitrogen (N), phosphorus (P) and sediment to Lake Tahoe. The "Lake Tahoe Source Attribution Study" (LTSAS) study was an extension of the previously completed "Sampling and Analysis for the Lake Tahoe Atmospheric Deposition Study" (LTADS), conducted by the California Air Resources Board, and the "Lake Tahoe Source Characterization Study."

The LTSAS included data analyses and receptor modeling performed on the LTADS and source characterization data sets, with the primary goal to identify and quantify the source types contributing to ambient PM levels in the Lake Tahoe Basin.
