The sites impressive documentation of data and sources is better than in many reference books. For example, each claim of toxicity references the studies establishing that claim and the scope of the EPA data is thoroughly explained. The overall design is professional and there are viewing options such as a text-only mode or a personalized home page focused on an individual area. The amount of data available on this site is huge, covering more than 17,000 facilities and more than 5,000 chemicals. The entire site is searchable, but using the six major sections, some of which are individually searchable, is more effective.
Some rural areas return a report on the whole state.
The report includes location and contact information for polluting facilities, the amount of pollution released, the health risks caused by the pollution, the ranking of the facilities as compared to the rest of the U.S., and the specific chemicals involved. It is searchable by name or CAS number and includes links to many other web sites with relevant information. Although any information presented by an activist group must be taken with a grain of salt, The Chemical Scorecard mostly sticks to well-documented facts. The only problem with the site is the overwhelming quantity of information. Students or faculty working in environmental or chemical fields will get the most out of this site.
