Databases

"The purpose of the Micropollutants Clearinghouse project is to provide an on-line, publically accessible, research resource on the legal, regulatory, institutional, policy, and related scientific aspects of micropollutants in fresh water systems. It is designed as a dynamic and robust database of documents, reports, information, analyses, articles, and other materials."

"EPA developed the NCOD to satisfy the statutory requirements set by Congress in the 1996 amendments to the Safe Drinking Water Act (SDWA) to maintain a national drinking water contaminant occurrence database using samples data for both regulated and unregulated contaminants in public water systems. This site provides a listing of water sample analytical data that EPA is currently using and has used in the past for analysis, rulemaking, and rule evaluation. The data have been extensively checked for data quality and analyzed for national representative-ness."

Allows you to "search over 11,000 full text, EPA documents online."

"A comprehensive set of digital spatial data that contains information about surface water features such as lakes, ponds, streams, rivers, springs and wells. Within the NHD, surface water features are combined to form "reaches," which provide the framework for linking water-related data to the NHD surface water drainage network. These linkages enable the analysis and display of these water-related data in upstream and downstream order."

"Stores and analyzes nutrient water quality data and serves as an information resource for states, tribes, and others in establishing scientifically defensible numeric nutrient criteria. It contains ambient data from our Legacy STOrage and RETrieval (STORET) data system, the US Geological Survey's National Stream Quality Accounting Network data and National Water Quality Assessment data, and other relevant sources such as universities and states/tribes. The ultimate use of the data is to derive ecoregional waterbody-specific numeric nutrient criteria. We will also use this database to develop ecoregionally representative nutrient criteria for all waterbodies of the United States."

Provides wetlands maps from the U.S. Fish and Wildlife Service.

"NEclimateUS.org (a.k.a. 'neXus') is a searchable online database that provides a gateway to climate information for the Eastern US. It summarizes needs for climate information as articulated in publications; identifies available data, products and services; and captures planned and on-going projects"

"Since 1974, the Heidelberg College Water Quality Laboratory has collected more than 90,000 water samples as part of its Ohio Tributary Monitoring Program. These samples have all been collected at U.S. Geological Stream Gaging Stations and have been analyzed for major nutrients and suspended solids. The sampling program has been designed to provide accurate and long-term pollutant loading data for Ohio's major tributaries to Lake Erie and the Ohio River. The data also provide uniquely detailed information on ambient water quality in the streams and support investigations on pollutant sources and transport."

Provides detailed information (heat of vaporization, water solubility, soil sorption) for more than 300 pesticides.

"An on-line database and interactive mapping system that highlights work by organizations and individuals to improve water quality and reduce practices that contribute to formation of the Dead Zone in the Gulf of Mexico."

"The Soil Climate Analysis Network (SCAN) is a comprehensive, nationwide soil moisture and climate information system designed to provide data to support natural resource assessments and conservation activities. Administered by the United States Department of Agriculture Natural Resources Conservation Service (NRCS) through the National Water and Climate Center (NWCC), in cooperation with the NRCS National Soil Survey Center, the system focuses on agricultural areas of the U.S. monitoring soil temperature and soil moisture content at several depths, soil water level, air temperature, relative humidity, solar radiation, wind, precipitation, barometric pressure, and more."

"The U.S. Environmental Protection Agency maintains two data management systems containing water quality information for the nation's waters: the Legacy Data Center (LDC), and STORET. The LDC contains historical water quality data dating back to the early part of the 20th century and collected up to the end of 1998. STORET contains data collected beginning in 1999, along with older data that has been properly documented and migrated from the LDC. Both systems contain raw biological, chemical, and physical data on surface and ground water collected by federal, state and local agencies, Indian Tribes, volunteer groups, academics, and others. All 50 States, territories, and jurisdictions of the U.S. are represented in these systems."
