This report includes data collected by the U.S. Geological Survey (USGS) starting in January 2019. These data append to long-term datasets extending back to 1974. This dataset supports the City of Palo Alto\u2019s Near-Field Receiving-Water Monitoring Program, initiated in 1994.\nThis data release is presented as two datasets each on its own child page. The first child page contains clam tissue metals data, sediment metals data, percentage fine sediment, total organic carbon, and the salinity of the overlying water. The second child page contains clam reproduction and benthic community data.
