More search options are available by clicking the "More Search Options..." link or by selecting the Search tab (http://toxmap.nlm.nih.gov/toxmap/search/setupSearch.do). The resulting search page allows you to search a chemical (in either TRI, Superfund, or both datasets) and specify more search options pertaining to TRI and Superfund. TRI-specific options include facility name, release medium, and on-site release amount. Superfund-specific options include site name and Hazard Ranking System (HRS) score.
TOXMAP can optionally zoom the map to the area of your search results. Note that in some cases this will zoom the map to an area larger than North America (e.g., to include Hawaii or the Mariana Islands). The "Zoom To" drop down box will zoom the map to a state or other pre-defined map area.
