       This table contains water level records and well characteristics for a network of thirty privately-owned
wells used to supply water for domestic use.  The network of wells was established as part of the National Water-
Quality Assessment (NAWQA) project in the Allegheny and Monongahela River Basin.
	The wells were sampled to assess the status of ground-water quality in areas underlain by a subarea of the
Appalachian Plateau Physiographic Province limited to the glaciofluvial sediments.  This sampling is termed a
Subunit Survey for the NAWQA Program.
	Explanation of column headings- SITE IDENTIFIER: 15 digit unique identifier based on site latitude (first
six digits),longitude (digits 7-13), and a two digit sequence number suffix.  LOCATION:  Name of 1:24000 U.S.
Geological Survey topographic quadrangle.  ELEVATION OF LAND SURFACE: Land-surface at well site, in feet above sea
level.  SOURCE OF DEPTH DATA: D, Driller; O, Owner; M, Measured. WATER LEVEL METHOD:  T, electric tape.

TABLE 1.--PESTICIDES ANALYZED IN GROUNDWATER.

REMARKS.--Water from each of the 30 wells in this study was tested for pesticides.  The table below lists the 47
    pesticides on this schedule, the unit of measure (micrograms per liter, µG/L) the U.S. Geological Survey
    National Water Information System parameter code, and the method detection limit (MDL).
         This pesticide schedule includes selected pesticides and metabolites that are efficiently partitioned
    from a water sample by solid-phase extraction and are sufficiently volatile and thermally stable for analysis
    by gas chromatography. 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. Pesticide compounds measured at
	or above the MDL in one or more samples are listed in the water-quality table following the schedule list.
	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 (<).

TABLE 2.--VOLATILE ORGANIC COMPOUNDS ANALYZED IN GROUNDWATER.

REMARKS.-- Water from each of the 30 wells in this study was tested for volatile organic compounds (VOC's).
	The table below lists the compounds on the schedule, the unit of measure (micrograms per liter, µG/L),
	the U.S. Geological Survey National Water Information System parameter code, and the method detection
	limit (MDL).
		The volatile organic compounds in this schedule included selected (VOC's) that are thermally
	desorbed from a water sample by the purge and trap method and then analyzed by gas chromatography.
		Each sample was analyzed for all of the compounds in this schedule. Volatile organic compounds measured
    at or above the MDL for one or more wells are listed in the water-quality table following the schedule lists.
    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 (<).
