EQuIS Data Tables and Fields Used in EnviroInsite

DT_ACTION_LEVEL

Field Name	Obligatory to Populate	Notes
ACTION_LEVEL_CODE	Yes	Used to populate action level selection list.
MATRIX	Yes	Must match DT_SAMPLE.MATRIX to be applied to a particular sample / result.
FRACTION	No	If not populated, the fraction field in DT_ACTION_LEVEL_PARAMETER must be populated.

DT_ACTION_LEVEL_PARAMETER

Field Name	Obligatory to Populate	Notes
PARAM_CODE	Yes
ACTION_LEVEL	Yes
UNIT	Yes	Value against which results are compared to determine exceedance.
ACTION_LEVEL_MIN	No	If populated, result will be flagged as exceedance based on value being less than this field’s value.
MATRIX	No	If not populated, the matrix field in DT_ACTION_LEVEL must be populated.
FRACTION	No	If not populated, the fraction field in DT_ACTION_LEVEL must be populated.

DT_COORDINATE

Plot types that are not location-dependent, such as boring logs, Stiff diagrams and Piper diagrams, may be created with no associated DT_COORDINATE record. Other plot types require a DT_COORDINATE value with a legitimate X and Y coordinate.

EnviroInsite determines the coordinate system recorded in the DT_COORDINATES table based on the value in the EQuIS data fields DT_FACILITY.COORD_TYPE and the associated record in RT_COORD_TYPE.SRID.

•An SRID value of 4326 in RT_COORD_TYPE.SRID indicates that the coordinate values are in latitude-longitude coordinates. In that case, the display coordinates will be in UTM, within the UTM zone at the center of the extent of the location positions.

•SRID values starting with 326 are presumed to indicate UTM coordinates within the northern hemisphere. SRID values starting with 327 are presumed to indicate UTM coordinates within the southern hemisphere. The final two digits in either of these cases are taken to be the UTM longitudinal zone. For example, an SRID value of 32617 would represent UTM longitudinal zone 17 in the northern hemisphere. State plane coordinates are not supported at this time.

•Other SRID values for MTM, State Plane or Spherical Mercator coordinates are not presently supported.

Field Name	Obligatory to Populate	Notes
SYS_LOC_CODE	Yes	Foreign key to DT_LOCATION
COORD_TYPE_CODE	Yes
IDENTIFIER	Yes
X_COORD Y_COORD	No*	Time-history plots, boring logs, Stiff diagrams, Durov diagrams and Piper diagrams can be created with these values not populated. The values are either provided as latitude-longitude pairs or assumed to have length units that are consistent with the coordinate system selected in EnviroInsite. If the user has selected either State Plane and metric or UTM, the horizontal units are in meters. If the user has selected State Plane and feet, the units are in feet. If the user has selected Local, the units are ambiguous and assigned within EnviroInsite. * These values are required to plot DT_DOWNHOLE_POINT_DATA in a boring log.
ELEV	No*	This value is used to determine the ground surface elevation. The program will assign the maximum value of the DT_COORDINATE.ELEV for records where the value is not populated. *If DT_WELL.TOP_CASING_ELEV is populated, DT_COORDINATE.ELEV is required to plot locations.
ELEV_UNIT	No	If not populated, the value will default to DT_WELL.DEPTH_UNIT, DT_LOCATION.UNITS or DT_FACILITY.ELEV_UNIT in that order.

DT_DOWNHOLE_POINT_DATA

Data from this table is used to generate profile charts on cross sections and strip logs.

Field Name	Obligatory to Populate	Notes
SYS_LOC_CODE	Yes	Foreign key to DT_LOCATION
DEPTH	Yes	Values are presumed to be in the same units as DT_FACILITY.ELEV_UNITS.
PARAM	Yes
PARAM_VALUE	Yes
PARAM_UNIT	No	The program does not make any unit conversions based on the PARAM_UNIT value. All PARAM_VALUES for a particular plot are presumed to be in consistent units.

FACILITY_ID	Yes	Must be populated in this instance and in all other tables where it appears, whether or not cited in this document.
COORD_TYPE_CODE IDENTIFIER	Yes	Change either of these to select rows within DT_COORDINATE.
ELEV_UNIT	Yes	All elevation and depth values will be converted to these coordinates.
X_MIN X_MAX Y_MIN Y_MAX	No	EnviroInsite uses these values as the default query limits and the initial view limits. If not populated, the program will use the calculated limits of the coordinates from DT_COORDINATE for the specified COORD_TYPE_CODE and identifier.

Geotechnical Data

If the Geotech Schema has been applied to the database, the following Geotechnical tables will be available in the Downhole Point Data section or Downhole Intervals section for boring logs:

•Downhole Point Data - DT_GEO_RESULT

•Downhole Intervals - DT_GEO_STANDARD_PENETRATION and DT_GEO_CORING

DT_LITHOLOGY

EnviroInsite treats lithology data as being derived from either borehole-scale inspection at a single location, or regional-scale observations representative of stratigraphic units. The latter, referred to as stratigraphy, may be used to generate geologic models in both 3D and on cross-sections. The former, referred to as geology, are not used within EnviroInsite to interpolate between boreholes. The stratigraphy values are required to conform to a layer-cake representation, although pinch-outs and missing units are handled within EnviroInsite.

Field Name	Obligatory to Populate	Notes
SYS_LOC_CODE	Yes	Foreign key to DT_LOCATION
START_DEPTH	Yes	Values are presumed to be in the same units as DT_FACILITY.ELEV_UNITS. Each record’s end-depth is given by the START_DEPTH of the succeeding interval (from top to bottom). For the deepest interval, the interval bottom is taken from the first non-null of DT_LOCATION.TOTAL_DEPTH or DT_WELL.DEPTH_OF_WELL.
MATERIAL_NAME	No	Should be populated for representation of small-scale variation in soil and rock. Used in boring logs and boreholes plotted on cross-sections and in 3D.

DEPTH_UNIT	No	Should be populated if DEPTH_OF_WELL field is populated.
TOP_CASING_ELEV	No	May be accessed by water level calculations where the Calculate Water Elevation option is selected and the top of casing elevation is designated as the reference point. Also used in plotting of wells on cross-sections and in 3D. * If this field is populated, populating DT_COORDINATE.ELEV is required in order to plot locations.
DEPTH_OF_WELL	No	EnviroInsite uses DT_LOCATION.TOTAL_DEPTH to determine total depth at a particular location. If TOTAL_DEPTH field is not populated, then DT_WELL.DEPTH_OF_WELL will be accessed. If both fields are null, then the total depth will be assigned a zero value.

DT_WELL_SEGMENT

The DT_WELL_SEGMENT table will be used to specify the elevation horizon of sample intervals for sample matrix values designated as such in the EQuIS Options dialog box. For example, when repeat samples are collected from the same interval (e.g. well screens), it may not be advisable to use the depth fields in DT_SAMPLE. In those cases, the sample intervals would be a record in the DT_WELL_SEGMENT table. The option to use DT_WELL_SEGMENT for the sample interval is selected by the EnviroInsite user as described in the Sample Interval Horizon Tab section of the EQuIS Options dialog box.
