Glossary
The glossary of terms below is listed for the purpose of this retrieval website. They do not necessarily
reflect actual EPA STORET field names.
STATIONS
COUNTY NAME County in which the station is located.
 
LATITUDE A latitude measurement indicates the angular distance (00 to 90 degrees) of a location north or south of the equator. North denotes a positive value for latitude, and south denotes a negative value. For example, the US has positive latitudes and Australia has negative latitudes. Latitude measurement is further specified by measuring the minutes (00 to 59 minutes) and seconds (00 to 59 seconds) of each degree. One degree of latitude equals 111.1 km or approximately 60 nautical miles.
 
LONGITUDE A longitude measurement indicates the angular distance (0 to 180 degrees) of a location west or east of the prime meridian. The prime meridian is a measurement line that is drawn from pole to pole around the Earth, passing through Greenwich, England. East denotes positive values; west denotes negative values. For example, Australia has positive longitudes and the US has negative longitudes. Longitude measurement is further specified by measuring the minutes (00 to 59 minutes) and seconds (00 to 59 seconds) of each degree.
 
DATUM The code that represents an acknowledged standard reference scheme of known coordinates from which calculations or measurements may be taken.
 
METHOD The code that represents the method used to determine geographic coordinates of a location point.
 
PRIMARY TYPE Type refers to the principle designation of the station (e.g., estuary, ocean, great lake, facility, etc.). Sometimes this primary station type can be further clarified.
 
SECONDARY TYPE Secondary type is a more detailed description of the principal designation of the station. Only some primary station types require the listing of a secondary type. For example, if the primary type is facility, the secondary type must specify what type of facility the station is ( e.g., Industrial, Municipal Sewage (POTW), Municipal Water Supply (PWS), etc.).
 
STATION ID This ID identifies the station within the organization; therefore it must be a unique ID within the organization. If you enter a duplicate ID, the system will reject the ID when you attempt to accept the station. Station ID is a 15-character, alphanumeric field.
 
STATION NAME This is the name by which an organization refers to a station. For example: Jones Point Station. Station Name is a 60-character, alphanumeric field.
 
USGS HUC CODE The US has been mapped into different drainage basins to identify where water will flow when it rains. These basins are identified by a series of hydrologic levels. The Hydrologic Unit Code (HUC) is an eight-digit number that describes the four hydrologic levels into which the US has been divided: Region, Sub region, Accounting Unit, and Cataloging Unit. For more information, visit http://water.usgs.gov/GIS/huc.html .
 
WBID Water Body ID. An identifier for a homogeneous portion of water that the Department will assess and evaluate for purposes of determining whether a TMDL will be required.
 
RESULTS
ACTIVITY DATE This is the date on which the sampling activity began (note: This entity could be interpreted differently for different activity types. For example, if the activity type was a data logger event, the activity date would most likely reflect the date of logger deployment).
 
ACTIVITY TYPE Indicates the nature of an activity; whether the activity performed is a field measurement/observation, a laboratory sample, a data logger event, or a trip QC sample.
 
ACTIVITY CATEGORY A descriptor used to distinguish different kinds of samples and different kinds of Measurements & Observations. The permitted value list is controlled by the choice of Activity Type (i.e. if ACTIVITY TYPE is ‘Sample’, CATEGORY may be ‘Routine Sample’ or ‘Field Replicate/Duplicate’).
 
ACTIVITY DEPTH This is the distance from the surface to the point in the water column at which the activity is conducted.
 
ANALYSIS DATE The date on which laboratory analysis of the sample for a particular result was performed.
 
CHARACTERISTIC A characteristic is the name of the biological, chemical or physical constituent being investigated. For example, in an analysis for fecal Coliform bacteria, the name of the characteristic is ‘Fecal Coliform’.
 
DATE RANGE In reference to the search engine interface, this is the date range chosen for a desired set of results.
 
DATA SOURCE Indicates the database of origin for retrieved result records (i.e. FLASTORET, FDEP (STORET), Legacy, etc.).
 
MINIMUM DETECTION LIMIT (MDL) Refers to the least amount of the target substance that could be detected by the instrument or analytical process that was used to determine the result. Above this value, the target substance is presumed to be present.
 
ORG ID The Org ID is the unique identifier of the State, Federal, local, academic, commercial, or other agency responsible for and in ownership of retrieved data. For a list of Org IDs and names, visit http://publicfiles.dep.state.fl.us/DEAR/storet/tsmorgan.pdf
 
PARAMETER CODE A previously used numeric code uniquely identifying a STORET parameter. This code indicates unit of measure, method, medium, and sample fraction for specific parameters. Originally used with Legacy STORET, these codes are still used as a reference by many agencies.
 
PRACTICAL QUANTITATION LIMIT (PQL) Represents the least amount of the target substance which could be quantified by the instrument/analytical process employed to determine the result. Values above the minimum and below the maximum quantitation limits are reported as valid numeric results.
 
PROCEDURE NAME The abbreviated name or identifying code of the analytical procedure.
 
PROJECT A project or survey is a planned activity or set of activities conducted for the purpose of collecting information concerning environmental quality.
 
RELATIVE DEPTH This is a general description of the depth at which the activity is conducted (i.e. surface, midwater, or bottom).
 
RESULT COMMENT This field is a free text metadata field (up to 1999 characters) that provides additional information about a result record, particularly if the result is anomalous or in some way questionable.
 
RESULT VALUE The alpha-numeric representation of the result of analyzing, measuring, or observing a Characteristic.
 
SAMPLE FRACTION When results are obtained from a physically partitioned sample. This field is used to select the portion of the sample that was associated with the results.
 
VALUE QUALIFIER A code describing specific quality assurance conditions as reported by the data provider. This field is exclusive to FDEP STORET. For definitions of the specific codes, visit http://www.dep.state.fl.us/water/storet/docs/EAS01-01_help.pdf .
