Glossary of Fields

Field Name	Description
Quad	Quadrant in which the work was performed - A, B, C, or D
ZIP_CODE	Postal zip code
Z CNSUS_TRCT	Census Tract, which is a geographical area used by the Census Bureau. Census tracts in the United States, Puerto Rico, and the Virgin Islands of the United States generally have between 1,500 and 8,000 people, with an optimum size of 4,000 people. The spatial size of census tracts varies widely depending on the density of settlement.
Index	No Unique Apartment Identifier

CLEAN_VS_TEST	Field to identify if the apartment was "Cleaned and then Tested" or "Tested Only"

CLEANUP_METHOD	Cleanup Method used - Scope A or B
Activity Type:	Monitoring Activity - Regular, or Special Pre(Cleaning) or Special Post(Cleaning) Monitoring
Sampling Location:	Location in which the sample was collected

SAMPLING_PROCEDURE	Aggressive or modified-aggressive air disturbance used prior to collection of samples
Collection Method:	A description of the procedure used to collect a sample of a specific matrix
Sample Category:	Field Sample, Field Blank or Lot Blank
Sampling Date	The date the sampling activity started
Sampling Time	The time the sampling activity started. This field was not used for wipe samples as there is not a time component associated with collecting wipe samples.
Sampling EndDate	The date the sampling activity completed. This field was not used for wipe sampling because all sampling was completed on the same day in which it started.
Sampling EndTime	The time the sampling activity completed. This field was not used for wipe samples as there is not a time component associated with collecting wipe samples.
Analysis	Sample analysis to be performed
Sample Number	A unique identification number assigned by Region 2 to field samples and field QC samples that appears on the Chain of Custody Record
Abbrev	Abbreviation for Analyte Category Analyte The name of the compound, element, parameter or substance an analytical process seeks to determine
Analytical Method	Method citation that indicates the analytical method used to perform the required analysis
Detected	Laboratory-assigned identifier indicating if an analyte has been detected above the method detection limit
Lab Flag	Code assigned by the analytical laboratory that qualifies the sample concentration for an analyte; U - analyte not detected at or above EPA Reporting Limit, R - result is unusable due to serious deficiencies in meeting quality control (QC) criteria of method, analyte may or may not be present, J - result is an estimated quantity due to method blank contamination or failure to meet method requirements
CAS Number	Chemical Abstract Number or Type of asbestos present in sample
Result	Number/Count of Fibers or Asbestos structures. This field was only used for asbestos measurements.
Result Units	Units of measure associated with a result. This field was only used for asbestos measurements.
Concentration	The relative amount of an analyte in a unit amount of the sample. This field was only used for asbestos measurements.
Concentration Units	The units of measure associated with concentration. This field was only used for asbestos measurements.
Sample Concentration	The relative amount of an analyte in a unit amount of the sample based on the sample volume/area collected
Sample Concentration Units	The units of measure associated with the Sample Concentration
Lab Sample Volume/Area	The size of the section, region or surface assessed to determine analytical results for asbestos and total fibers, in square mm (mm2)
Lab Reported Volume/Area	For asbestos - the volume of air (in liters) sampled, for wipe samples - the area of surface (in cm2) wiped
Reporting Limit	A minimum limit that a compound, element, parameter or substance is reported
MDL/ML Units	Units of measure associated with the Reporting Limit
Lab Result Comments	Pertinent remark or explanation associated with any issues or circumstances that may affect the results for an analyte
Validation Flag	Identifier used to flag sample results/concentrations; N = Not Analyzed, O = Overloaded, For PCMe Analyte=Asbestos - TEM >=5u F = sample concentration >0.0009 P = sample concentration <=0.0009, For TEM Analyte=Asbestos - TEM >0.5u (Total) E = sample concentration >0.022 P = <=0.022, For Fibers E = >0.0100 P = <=0.010
Validation Comments	Pertinent remark or explanation associated with any issues or circumstances that may affect the results for an analyte
