The Sampling Locations selected from the map are listed below. Use the checkboxes to select/deselect individual Sampling Locations. Initially the Selected Parameters list includes any parameter for which there is data from at least one Sampling Location. Refine the list to include those parameters of interest by clicking the Modify button and selecting/deselecting parameters using the checkboxes. Choose an Activity Date Range by using the date selection boxes or typing in dates in the form MM/DD/YYYY. Both Start Date and End Date are optional; leave Start Date or End Date blank to select data collected after or before a specific date, respectively. Leave both blank to select all data within the activity date range for the chosen Sampling Locations.
