ChemIDplus Lite is a chemical dictionary that provides names, synonyms and structures for over 400,000 chemicals.
EPA Green Chemistry
Green chemistry is the design of chemical products and processes that reduce or eliminate the generation of hazardous substances. EPA's efforts to speed the adoption of this revolutionary and diverse discipline have led to significant environmental benefits, innovation and a strengthened economy.
EPA Toxic Release Inventory (TRI) Program
What is the TRI? The Toxics Release Inventory (TRI) is a resource for learning about toxic chemical releases and pollution prevention activities reported by industrial and federal facilities.
National Renewable Energy Laboratory
The National Renewable Energy Laboratory (NREL) is transforming energy through research, development, commercialization, and deployment of renewable energy and energy efficiency technologies.
NIST Material Safety Data Sheets
Search for MSDS and certificates. PDFs when available may be viewed online.
PubChem (National Library of Medicine)
PubChem is the world's largest collection of freely accessible chemical information. Search chemicals by name, molecular formula, structure, and other identifiers. Find chemical and physical properties, biological activities, safety and toxicity information, patents, literature citations and more.
USGS Alkalinity Calculator
The Alkalinity Calculator will analyze the titration curve and calculate the alkalinity or acid neutralizing capacity (ANC) of the sample using one or more of several different methods.
USGS DOTABLES (Dissolved Oxygen Solubility tables)
DOTABLES is an on-line program that generates tables of dissolved oxygen (DO) solubility values and (or) salinity correction factors over a range of user-specified values for water temperature, barometric pressure, and salinity or specific conductance. In addition to generating tables, DOTABLES can compute a single-value of oxygen solubility and percent saturation for a specific instance of temperature, pressure, and salinity.
USGS National Water Quality Laboratory
The NWQL offers a wide-range of environmental analytical services, including inorganic, organic, and radiochemical constituents, and provides high-quality, reproducible data.

United Nations Environmental Data Explorer
The Environmental Data Explorer is the authoritative source for data sets used by UNEP and its partners in the Global Environment Outlook (GEO) report and other integrated environment assessments. Its online database holds more than 500 different variables, as national, subregional, regional and global statistics or as geospatial data sets (maps), covering themes like Freshwater, Population, Forests, Emissions, Climate, Disasters, Health and GDP. Display them on-the-fly as maps, graphs, data tables or download the data in different formats.
