About STORET
The U.S. Environmental Protection Agency (EPA) maintains two data management
systems containing water quality information for the nation's waters: the
Legacy Data Center, and STORET.
The Legacy Data Center, or 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., along with portions of Canada and Mexico, are
represented in these systems.
Each sampling result in the LDC and in STORET is accompanied by information
on where the sample was taken (latitude, longitude, state, county, Hydrologic
Unit Code and a brief site identification), when the sample was gathered, the
medium sampled (e.g., water, sediment, fish tissue), and the name of the
organization that sponsored the monitoring.
In addition, STORET contains information on why the data were gathered;
sampling and analytical methods used; the laboratory used to analyze the
samples; the quality control checks used when sampling, handling the samples,
and analyzing the data; and the personnel responsible for the data.
The LDC and STORET are web-enabled. With a standard web browser, you can
browse both systems interactively or create files to be downloaded to your
computer. If you want to browse or download data from the LDC or STORET, click
on "Obtaining Water Quality Data" on the main STORET homepage.
