                                            COAL MINING LAND-USE STUDY

   This table contains water level records and well characteristics for a network of thirty five 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 downgradient of reclaimed surface
coal mines. These areas are underlain by a subarea of the Appalachian Plateau Physiographic Province limited to
the Pittsburgh Series fractured rock.  This sampling is termed a Land-Use Study for the NAWQA Program. Five wells
were selected as reference sites. These wells fall inside the Land-Use Study boundary but are not influenced by
mine drainage.
   Explanation of column headings- SITE IDENTIFIER: 15 digit unique identifier based on site latitude (first

TABLE 1.--VOLATILE ORGANIC COMPOUNDS ANALYZED IN GROUND-WATER.

REMARKS.-- Water from each of the 35 wells in this study was tested for volatile organic compounds (VOC's).
   The table below lists the compounds analyzed, 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, result will be qualified 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 (<).
