Agp L ~ potential acidity exceeds the neutralization potential <br />The list includes all Phase I <br />parameters which had values that exceeded unsuitable levels or had maximum concentration <br />greater than 50 percent of the threshold value. Total combustible solids, an indicator of <br />.... the fire hazard potential, wilt not be analyzed on Phase II samples since carbonaceous <br />.- overburden materials, other than the Lennox coal seam, are not present at Yoast. No <br />-. mercury or arsenic analyses are warranted at Yoast due to the extremely remote chances of <br />any potential mercury or arsenic toxicity. There have been no documented cases of arsenic <br />or mercury toxicity to plants or to animals under normal conditions (Munshower, 1983). <br />Mercury and arsenic toxicity is limited to industrial or agricultural situations where <br />mercuric or arsenic fungicides or other contaminants are used (Barrett et al., 1980). <br />- Nitrate analyses will be completed on the Phase II samples because elevated levels have <br />been previously reported i erbu den-samf~les_ m the Seneca II and II-W mine areas. <br />Manganese and lead ana.lyse~ecortmlende~d-~o confirm or deny the drill stem <br />• ~ contamination hypothesis. <br />Laboratory Methods <br />/ 1 / ~ J. <br />The analysis list for the four Phase II salmple s tes wi 11 include pH, EC, saturation <br />percent, scid base potential, iron, manganese, ni rate, and particle size.
