TITLE: US EPA STORAGE AND RETRIEVAL (STORET) SYSTEM FOR WATER QUALITY MONITORING IN FLORIDA - JULY 2012

Geodataset Type:       SHAPEFILE
Geodataset Feature:    Point
Feature Count:         99772
GENERAL DESCRIPTION:
This data set contains locations of and information on water quality monitoring sites that are within EPA's Storage and Retrieval (STORET) System. Water quality monitoring information comes from EPA's STORET System, a repository of physical, chemical and biological monitoring data from state and federal agencies, watershed organizations, volunteer groups and many others. Surface water, Ground water, and Others are general categories for more specific STORET Station Types. Water quality monitoring is a crucial aspect to protecting water resources. State, Tribal, and Federal agencies must monitor lakes, streams, rivers, and other types of water bodies to assist them in determining water quality condition. From these monitoring activities, water quality monitoring data is generated. Without this data, water resource managers cannot know where pollution problems exist, where we need to focus our pollution control energies, or where we've made progress. The STORET Data Warehouse is EPA's repository of the water quality monitoring data collected by water resource management groups across the country. These organizations, including states, tribes, watershed groups, other federal agencies, volunteer groups and universities, submit data to the STORET Warehouse in order to make their data publically accessible. Data can then be re-used for analysis. WQX is the framework by which organizations submit data to the Warehouse. This is an update to the FGDL layer EPASTORET_MAY11.

LATITUDE Latitude of facility, site, or operable unit, in Decimal Degrees.

LONGITUDE Longitude of facility, site, or operable unit, in Decimal Degrees.

USNG_FL_1K Facility's 1-kilometer United States National Grid (USNG) address. The USNG is an alpha-numeric reference system based on the UTM coordinate system and is similar to the Military Grid Reference System. Use of the USNG ensures a uniform grid mapping and positional reporting system for search and rescue, emergency planning, response, and recovery.

DESCRIPT Based on the field LOCATION.

FGDLAQDATE The date FGDL acquired the data from the Source.

AUTOID Unique ID added by GeoPlan

The attributes provided within this data set are derived from the USEPA's 
Envirofacts Data warehouse.  For additional background on the attributes listed 
within this service, please visit http://www.epa.gov/enviro/html/ef_overview.html.
USER NOTES:
Locations are tested and reported individually
Completeness of the data set varies for individual features.
GeoPlan relied on the integrity of the attribute information within
the original data.
The STORET Data Warehouse
All data supplied to EPA since January 1, 1999 have been placed in the STORET 
Data Warehouse. A full description of the design of this system can be examined 
on our introduction page.

The STORET Data Warehouse is currently receiving new data on a regular basis,
including data being submitted via WQX, and will continue to do so for the 
foreseeable future. Downloads performed for the same sites may differ over time 
as a result of the addition of new data by their owners.
http://www.epa.gov/storet/dbtop.html

The Storage and Retrieval (STORET) System is used by EPA programs, regions, 
states, and water programs for monitoring water quality.

FRS uses a best-pick algorithm to provide horizontal positional information.  This 
assigns the latitude and longitude with the best accuracy value to each facility.  
Because information in FRS is collected across numerous states and programs, 
positional accuracy for the data set varies for each individual feature and is stored 
on a record-level basis. Overall horizontal positional accuracy for the entire data 
set fluctuates as new information is received and is not estimated for the entire 
data set within this record. For more information on accuracy of FRS locations, 
visit http://iaspub.epa.gov/sor_internet/registry/facilreg/home/overview/home.do

This data is provided 'as is' and its vertical positional accuracy
has not been verified by GeoPlan

EPA: None. Please check sources, scale, accuracy, currentness and other 
available information. Please confirm that you are using the most recent copy of 
both data and metadata.  While EPA has used its best efforts to include complete 
and accurate information in this system, EPA cannot be held responsible for errors
or omissions and is not liable for any direct, indirect or consequential damages 
resulting from using this information. Reliance on the information contained in this 
system by any party cannot be used as a defense in any administrative or judicial 
proceeding. In such proceedings, the specific language of the relevant regulation 
or statute is binding. Acknowledgement of the EPA would be appreciated.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. The University of Florida GeoPlan Center
shall not be liable for any damages suffered as a result of using,
modifying, contributing or distributing the materials.

A note about data scale: 

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

1:24000 scale datasets 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 datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets 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 analysis. 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 webpage at:
