The Substance Registry Services (SRS) is the authoritative resource for basic information about substances of interest to the U.S. EPA and its state and tribal partners. Substances, particularly chemicals, can have many valid synonyms. For example, toluene, methyl benzene, and phenyl methane, are commonly used names for the same chemical. EPA programs collect environmental data for this chemical using each of these names, plus others. This diversity leads to problems when a user is looking for programmatic data for toluene but is unaware that the data is stored under the synonym methyl benzene. For each substance, the SRS identifies the statutes, EPA programs, as well as organization external to EPA, that track or regulate that substance and the synonym used by that statute, EPA program or external organization. Besides standardized information for each chemical, such as the Chemical Abstracts Services name and the Chemical Abstracts Number and the EPA Registry Name (the EPA standard name), the SRS also includes additional information, such as molecular weight and molecular formula. Additionally, an SRS Internal Tracking Number uniquely identifies each substance, enabling cross-walking between synonyms. EPA is providing a large .ZIP file providing the SRS data in CSV format, and a separate small metadata file in XML containing the field names and definitions.

The Socrata Open Data API (SODA) allows software developers to access data hosted in Socrata data sites programmatically. Developers can create applications that use the SODA APIs to visualize and “mash-up” Socrata datasets in new and exciting ways. Create an iPhone application that visualizes government spending in your area, a web application that allows citizens to look up potential government benefits they'd overlooked, or a service that automatically emails you when new earmarks are added to bills that you wish to track.
To start accessing this dataset programmatically, use the API endpoint provided below. For more information and examples on how to use the Socrata Open Data API, reference our Developer Documentation.

Using a digitally signed dataset, it is possible to prove using cryptographically secure methods that a particular copy of a Socrata dataset has not been tampered with. This is useful if, for instance, you are looking to publish findings based on this data, and you want to be able to prove its integrity.
To obtain a signed version of this dataset, simply click on the link below to generate a key and begin the download. The key and downloaded data are specific to the current version of this dataset; if the owner updates the dataset in the future, you will have to restart the process to get the new data. Publish the downloaded data along with the key that you receive, and using the instructions found within the downloaded package, third parties will be able to confirm that your data is legitimate.
To generate a signed version of this dataset, simply click on the link below to generate a key. Note that if you update this dataset in the future, you will have to return and regenerate the key in order for consumers to again have access to it. Also note that this process involves operations on the entirety of the data, so it may take some time if your dataset is very large, or contains large attachments.
Only dataset owners may generate signed keys.
