Deposition Monitoring Locations

Wet deposition is monitored at 44 national parks and dry deposition is monitored at 29 national parks. Some sites have been operating for over 20 years. The NPS recently started monitoring mercury in wet deposition and currently has monitors in 13 national parks. More information on the monitoring sites and access to the data is available on the NADP and CASTNet web pages directly. The graphic below illustrates the different types of monitoring at NPS deposition monitoring locations. The same information is available in table format below the map.
