REMARKS.--The following data are for analytes from the National Water Quality laboratory (NWQL)
  schedule 2010--pesticides in filtered water.  Samples are filtered through a glass-fiber membrane filter with
  openings that are 0.7 microns in size to remove sediment and microorganisms.  The filtered water is field
  extracted on C-18 Solid Phase Extraction Cartridges and analyzed by a gas chromatography/mass spectrometric
  detector.
    The method detection limit (MDL) provides an index to indicate where measurement uncertainty
  is increased.  When an analyte is detected and all criteria for a positive result are met, the concentration
  is reported.  If the concentration is less than the MDL, an 'E' code will be reported with the value.  If the
  analyte is qualitatively identified as present, but the quantitative determination is substantially more
  uncertain, the NWQL will identify the result with an 'E' code even though the measured value is greater than
  the MDL.  A value reported with an 'E' code should be used with caution.  When no analyte is detected
  in a sample, the default reporting value is the MDL preceded by a less-than sign (<).

REMARKS.--The following data are for analytes from the National Water Quality laboratory (NWQL)
  schedule 2051--pesticides in filtered water.  Samples are filtered through a glass-fiber membrane filter with
    openings that are 0.7 microns in size to remove sediment and microorganisms.  The filtered water is field
    extracted on Carbopak B solid phase extraction cartridge and analyzed by high performance liquid
    chromatography.
    The method detection limit (MDL) provides an index to indicate where measurement uncertainty
  is increased.  When an analyte is detected and all criteria for a positive result are met, the concentration
  is reported.  If the concentration is less than the MDL, an 'E' code will be reported with the value.  If the
  analyte is qualitatively identified as present, but the quantitative determination is substantially more
  uncertain, the NWQL will identify the result with an 'E' code even though the measured value is greater than
  the MDL.  A value reported with an 'E'code should be used with caution.  When no analyte is detected
  in a sample, the default reporting value is the MDL preceded by a less-than sign (<).
