Description:

Abstract:: This dataset contains locations of monitoring stations and statistical summaries of water quality monitoring for 47 physical and chemical-related parameters.
Purpose:: This data set was prepared to support the U.S. EPA BASINS Better Assessment Science Integrating Point and Nonpoint Sources System. 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 5year intervals from 19701994 and for the period from 19951997. 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.

THE DATA INCLUDED IN THIS APPLICATION ARE BASED ON INTERPRETATION OF AVAILABLE INFORMATION AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING.

Scale is an important factor in data usage. Certain scale data sets are not suitable for some projects, analysis, or modeling purposes. Please be sure you are using the best available data.

1:24000 scale data sets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries.

1:100000 scale data sets are recommended for projects that are at the multi-county or regional level. 1:250000 scale data sets are recommended for projects that are at the regional or state level or larger.

Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our web pages at: <http://www.geoplan.ufl.edu/education.html>

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: The coverage feature attribute table contains the primary attributes of the monitoring stations. The related tables WQXXXX, contain the statistical summaries for these stations. The WQPARM and WQCRIT tables contains the STORET parameter codes and definitions. This data set provides statistical summaries of water quality monitoring for 47 physical and chemicalrelated parameters. The parameter specific statistics were computed by station for 5year 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.

Logical_Consistency_Report:

Certain node/geometry and topology (GT)-polygon/chain relationships are collected or generated to satisfy topological requirements. Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout the transfer, and the chains representing the limits of the file (neatline) are free of gaps. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data outside the enclosed region are ignored and all data crossing these geographically straight lines are clipped at the neatline. (Exception: During the QA/QC process all data is examined and if errors are found and corrections are possible, then data is corrected accordingly. This process is documented in the Process_Step.) Data within a specified tolerance of the neatline are snapped to the neatline. Neatline straightening aligns the digitized edges of the digital data with the generated neatline, that is, with the longitude/latitude lines in geographic coordinates. All internal polygons are tested for closure. Certain attributes and/or entities, e.g. closure line, convey data quality information. When information to be encoded in the subfield is known to be not applicable (undefined, not relevant), then the subfield is valued by a string of "9s"; and when the information to be encoded is relevant but unknown (or missing), then the subfield is valued by a string of "9s."

Process_Step:

Process_Description:: The process step describes, in general, the process used in the production of data sets. The originating agencies created the original spatial coverage. GeoPlan, during the QA/QC process included the following aspects: (1) Reprojected data to FGDL Albers (2) Set Precision to DOUBLE (3) Set Tolerances to FGDL Standards.
