     SUBUNIT OF THE PITTSBURGH SERIES IN THE FRACTURED ROCK OF THE APPALACHIAN PLATEAU PHYSIOGRAPHIC PROVINCE

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 Pittsburgh Series fractured rock.  This sampling is
termed a Study-Unit 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.  AQUIFER CODE: 317WBRG, Waynesburg Formation; 321CNMG, Conemaugh Formation; 321CSLM, Casselman Formation;

TABLE 1.--PESTICIDE SCHEDULE FOR GROUND-WATER WELLS.

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 (mircograms per liter, µG/L) the U.S. Geological Survey
	National Water Information System parameter code, and the method detection level.  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 method detection limit (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 SCHEDULE FOR GROUND-WATER WELLS

REMARKS.-- Water from each of the 30 wells in this study was tested for Volatile Organic Compounds.  The table
    below listes 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 reporting level.  Each sample was
    analyzed for all of the compounds in this schedule. Compounds measured at or above the reporting level 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 (<).
