Description:
Abstract:
This data set provides statistical summaries of water quality monitoring
for 47 physical and chemical-related parameters. The parameter specific
statistics were computed by station for 5-year intervals from 1970 to 1994
and a three year interval from 1995 to 1997. The data are extracted from
the U.S. EPA Storage and Retrieval of US Waters Parametric Data (STORET)
which is contributed by a number of organizations including federal,
state, interstate agencies, universities, contractors, individuals and
water laboratories. Data updates are performed weekly. Each provider of
data is responsible for the data it submits to STORET.
For distribution with BASINS v.2.0, the spatial attributes of the database
were prepared in Arcview shape file format while selected relational
attributes were prepared in Arcview DBF file format.
Purpose:
The STORET database serves as a repository of waterway parametric data,
including information on ambient, intensive survey, effluent and
biological water quality.
Supplemental_Information:
Intended use of data:
This data set was prepared to support the U.S. EPA BASINS (Better
Assessment Science Integrating Point and Nonpoint Sources) System.

Process_Description:
The BASINS Water Quality Monitoring and Data Summaries for the
conterminous U.S. are created by retrieving the source data from the
STORET database using the STORET MEAN program. Monitoring
stations characterized as ambient stream, lake, reservoir, canal,
estuary or ocean were selected.
Summary statistics were computed by the program by station for 5-year
intervals from 1970-1994 and for the period from 1995-1997. Statistics
include number of observations, standard deviation, mean, 15th, 25th,
50th, 75th and 85th percentiles. A BASINS water quality station ID was
assigned to each station in order to facilitate links and joins within
BASINS between station data and the monitoring data summary.
For distribution with BASINS v2.0, ARCVIEW shapefiles which included the
spatial extent of each of the ten U.S. EPA Regions, plus the 8-digit
hydrologic units that crossed region boundaries were prepared to
indicate the geographic locations of the monitoring stations within the
region.
