<br />TABLE A <br />NEW HORIZON MINE <br /> <br />SUMMARY OF ANALYTICAL DATA <br />SELECTED HYDROLOGICAL MONITORING PARAMETERS <br />1992 (1ST QUARTER) - 1994 (3RD QUAATER) <br />PARAMETER UNIT MIN. MAX. REMARKS <br />Acidity mgll 0 208 The maximum value pertains to Well GW- <br /> N14 (coal); otherwise, exduding this well, <br /> the maximum value is 33 in Well GW-N20 <br /> (coal). Well GW-N74 has consistently <br /> shown higher acidity. tt appears to have <br /> penetrated through a pyritic zone In the coal. <br /> Most of the results show a value of zero. <br />Alkalinity mgll 0 845 No significant variation over time in <br /> individual locations. <br />Aluminum mgll -0.25 20.1 The maximum value pertains to Wells GW- <br /> N14; otherwise tl~ maximum value is 1.1 in <br /> Well GW-N20. No significant variation over <br /> dme in individual locations. <br />Arsenic Ngll -10 20 The maximum value pertains to Well GW- <br /> N13 (underburden), The neM highest value <br /> Is 24 for Weli GW-N40 (alluvium) for the <br /> Znd quarter, 1993. Of the remaining data, <br /> the maximum value is 7. No significant <br /> variation over time in individual locations. <br />Barium Ngll -100 130 No significant variation over tlme in <br /> individual locations. <br />Boron ugA -20 490 No significant variation over time in <br /> individual locations. <br />Cadmium {rg/I -50 270 Na significant variation over time in <br /> Individual locations. <br />Copper Ngll -50 -10 No significant variation over tlme in <br /> individual locations. <br />
