Human Health Benchmarks for Pesticides

Environmental Protection Agency.

"Advanced testing methods now allow pesticides to be detected in water at very low levels. These small amounts of pesticides detected in drinking water or source water for drinking water do not necessarily indicate a health risk. The EPA has developed human health benchmarks for approximately 350 pesticides to enable our partners to better determine whether the detection of a pesticide in drinking water or source waters for drinking water may indicate a potential health risk."

Integrated Risk Information System (IRIS) Database for Risk Assessment

Environmental Protection Agency.

"A compilation of electronic reports on specific substances found in the environment and their potential to cause human health effects. (IRIS) was initially developed for EPAstaff in response to a growing demand for consistent information on substances for use in risk assessments, decision-making and regulatory activities. The information in (IRIS) is intended for those without extensive training in toxicology, but with some knowledge of health sciences."

International Stormwater Best Management Practices (BMP) Database

MyWATERS Mapper also contains water-related geographic themes such as 12-digit watersheds, the national stream network known as the National Hydrography Dataset, and other water-related map layers. MyWATERS Mapper enables you to create customized maps at national and local scales."

National Contaminant Occurrence Database

EPA. Office of Water.

"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."

National Environmental Methods Index

Environmental Protection Agency; DOI. United States Geological Survey.

Provides "a mechanism to compare and contrast the performance and relative cost of analytical, test, and sampling methods for environmental monitoring." The index can be used to compare methods based on analyte, media and performance data. NEMI is a project of the Methods and Data Comparability Board, developed with funding from the U.S. Environmental Protection Agency and the U.S. Geological Survey.

Environmental Protection Agency logo National Environmental Publications Information System

National Estuaries Restoration Inventory

DOC. National Oceanic and Atmospheric Administration.

"Created to track estuary habitat restoration projects across the nation. The purpose of the inventory is to provide information on restoration projects in order to improve restoration methods and to track acreage restored toward the Act's one million-acre goal." [NOAA requires certificate authorization for access to this site.]

National Hydrography Dataset

DOI. United States Geological Survey.

"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."

National Land Cover Database (NLCD)

Multi-Resolution Land Characteristics (MRLC) Consortium

Serves as the definitive Landsat-based, 30-meter resolution, land cover database for the United States.
