What Can I Do Here?
This tool helps you explore which parameters were sampled at a station or which stations have data for a parameter. Also explore where detections and exceedances have occurred and for which parameters. Your query produces a chart of the number of samples, number of samples where a parameter was detected, and the number of samples that exceed a benchmark. A table also provides the minimum and maximum measurements and the lowest applicable benchmark source.

How Do I Proceed?
Select exploration by station or parameter by clicking the appropriate circle. To see data for a parameter group at a particular station, select station and then the parameter group of interest. Only parameter groups that have data that match your query will appear. Narrow your exploration to a particular monitoring program and time period if desired. Exceedance is defined as a concentration greater than any of the selected benchmarks.
