99 Observed properties (data types) available - with data from 1969-05-15 to 1975-12-29
71 Sampling activities
Discrete sample data are derived from manual field collection and laboratory analysis of physically collected samples collected during a visit to the monitoring location.

The table below summarizes the discrete field and laboratory sample results that have been collected at this monitoring location. The sample results can be downloaded from the Download Discrete Sample Data  page or by clicking the observed property link in each row of the table. The sample data are now identified by observed property, replacing the parameter and pcode USGS has used for many years. Additional information and explanation is provided in the Observed Properties and Parameter Codes section of the Code Dictionary tools .

The summary of sample data table is produced with the summary service API
