The analysis list for the four Phase II sample sites will include pH, EC, saturation <br />percent, acid base potential, iron, manganese, nitrate, and particle size. Sulfur <br />fractionation (i.e., pyritic, sulfate, and organic) analyses will only be performed when <br />potential acidity exceeds the neutralization potential. 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, will 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 previousl in overburden samples from the Seneca I I and II-W mine areas. ~. <br />/f~ Manganese a d iron lyres are recommended to confirm or deny the drill stem , <br />lJ 1 contamination hypothesis. <br />Laboratory Methods <br />The parameter/procedure list to be used for the Phase II samples collected from the Yoast <br />study area is listed in Table 2. <br />Cited Literature <br />American Society for Testing Materials (ASTM). 1960.
