#  METADATA Data Description:  
#
#  ABSTRACT:  This data set contains water-quality results of major and 
#             minor ions detected in groundwater blank samples collected by the
#             U.S. Geological Survey National Water-Quality Assessment
#             Project, May 2012 through December 2013
#
#  SUPPLEMENTAL INFORMATION: Data included in this file are from all wells 
#             that were sampled for blank quality assurance samples. 
#             Types of blank samples include equipment blanks, source 
#             solution blanks, and field blanks. Blanks are used to test 
#             for bias from an unintentional introduction of contamination
#             to environmental samples.  
#
#             There are 25 tables, including this one, that are part of the 
#             Report. Table 1 has a list of all wells that were sampled during 
#             the time period represented by this report.  Table 2 lists 
#             all of the constituents for which samples were analyzed. 
#             Analytical results of environmental samples are presented 
#             in tables 3-11. Analytical results of quality control samples
#             are presented in appendix tables A3-2 through A3-15.
#
#             Data in this file are separated by a tab-delimiter. The data 
#             are preceded by lines of metadata describing the contents of 
#             the file. Metadata lines begin with a # character.  The 
#             last line of the metadata is numbered. The first line after 
#             the last line of metadata contains the column names of the 
#             data. To import these data into a spreadsheet application,
#             begin importing after the last line of metadata.

#
#   DATA FIELDS:
#
#   Data Field: Network_type
#   Data Field Type: string
#   Data Field Description: Type of network
#   Data Field Values:

#   Data Field Description: Sequential site identifier. Sites 
#        listed within a network may not be contiguously numbered.  
#        Some sites within a network may not have been sampled for 
#        various reasons (including well was destroyed or damaged, 
#        had too little water to sample, or permission to sample 
#        could not be obtained from the land owner).
#
#   Data Field: State
#   Data Field Type: string
#   Data Field Description: 2-letter postal abbreviation for the 
#        state in which the site is located
#   
#   Data Field: Sample_date

#   Data Field Description: Measurement date mm/dd/yyyy
#
#   Data Field: Sample_time
#   Data Field Type: numeric
#   Data Field Description: Time of measurement, in local military time
#
#   Data Field: Blank_type
#   Data Field Type: string
#   Data Field Description: Type of blank quality assurance sample.
#   Data Field Values:
#        Equipment = Equipment blank.  Equipment blanks are for 
#            testing that equipment is clean and free of contamination.
#        Source Solution = Source Solution blank. Source solution blanks 
#            are used to test that the water used to make the 
#            blank is free of contamination. 
#        Field = Field blank. Field blanks are used to test for any 
#            contamination that may be introduced during sample collection, 
#            processing, handling, and the environment around where the 
#            sample was collected.
#
#   Data Field: Number_of_detections
#   Data Field Type: numeric
#   Data Field Description: Number of compounds detected at the site
#
#   Data Field: Number_of_detections_above_the_reporting_level
#   Data Field Type: numeric
#   Data Field Description: Number of compounds that were detected at a
#        concentration above the reporting level shown 
#        in table 2 of the subject report.
#
#   Data Field GROUP: Major Ions. 
#        There are two data fields for each water-quality parameter. 
#        The first data field, with a label that begins with "R_", provides 
#        a remark code for each constituent result. The second data field, 
#        with a label that begins with "V_", provides the result value. 
#        The prefixes "R_" and "V_" in the data field labels are followed 
#        by a 5-digit number that gives the USGS parameter code (pcode) 
#        for the water-quality parameter. The pcodes in the data field 
#        labels are followed by the name of the water-quality parameter. 
#        A value of NC in the V_ value field indicates that a sample was 
#        not collected for that analyte. A value of -- in the V_ value field 
#        indicates analyte was not detected.

#
#      Remark   Description
#      ------   ------------------------------------------------------------
#        <      Not detected. Value reported as less than the Maximum Long-
#               Term Method Detection Level. Actual value is less than the 
#               value shown.
#
#        E      Detected. Concentration is estimated. Reasons for estimated 
#               concentration include (Childress and others, 1999):
#               1. Result was below the laboratory reporting level but
#                  above the long-term method detection level, or, for
#                  information-rich methods, result was below the 
#                  long-term method detection level.
#               2. Result was extrapolated above the calibration curve.
#               3. Data quantification was not performed according to 
#                  method-specific criteria.
#               4. Performance of the analyte does not meet acceptable 
#                  method-specific criteria.
#               5. Deviation from the standard operating procedure was 
#                  required.
#               6. Some moderate losses occurred in sample preparation 
#                  but were not quantifiable.
#               7. Moderate matrix interference conditions occurred.
#
#         --     No remark. If Value column is 'NC' then no sample was 
#                collected.  If Value column has '--' then no analyte 
#                was detected. If Value column has a number, then the 
#                analyte was detected.
#
#         >     Greater than. Actual value is greater than the value shown.
#
#         R     radiochemistry not detected, result was below the sample 
#               specific critical level
#
#         V     Analyte was detected in both the environmental sample and 
#               in the associated blanks.  Value may be affected by 
#               contamination.
