REMARKS.--Samples are filtered through a glass-fiber membrane filter with openings that are 0.7 microns in size to
   remove sediment and microorganisms. Therefore, this schedule is suitable for compounds dissolved in water.
   Each sample was analyzed for all of the compounds in this schedule.  The 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
   (<).
