A toxicity/tissue residue database for aquatic organisms exposed to inorganic and organic chemicals. This database is a resource for use in the systematic investigation of hypotheses related to effect/residue relationships.

The AirData site provides access to yearly summaries of United States air pollution data, taken from EPA's air pollution databases. AirData has information about where air pollution comes from (emissions) and how much pollution is in the air outside our homes and work places (monitoring).

The National Status and Trends Program is comprised of three nationwide programs: Benthic Surveillance, Mussel Watch, and Bioeffects. These programs are in place to observe estuarine and coastal waters nationwide to describe the current status and detect changes in the environmental quality using long-term, continuous monitoring. Special Studies is another program which assesses the environmental impacts of different events, such as Hurricane Katrina. Mussel Watch is the longest continuous, nationwide contaminant monitoring program, running from 1986 to present, analyzing sediment and bivalve tissue for organic contaminants and trace metals. Bioeffects Assessment Program has completed over 30 regional studies since 1991, studying sediment contaminants, toxicity, and the condition of benthic communities. Benthic Surveillance monitored chemical concentrations of bottom-swelling fish and sediments, as well as biological effects of contaminant exposure. This project was discontinued in 1993.

Envirofacts integrates information from a variety of EPA's environmental databases. Each of these databases contains information about facilities that are required to report activity to a state or federal system. Using this API, you can retrieve information.

The Envirofacts Data Warehouse contains information from select EPA Environmental program office databases and provides access about environmental activities that may affect air, water, and land anywhere in the United States. The Envirofacts Warehouse supports its own web enabled tools as well as a host of other EPA applications.
