' Water samples were kept refrigerated and delivered to the water <br />quality lab either the day of collection or overnight. Field <br />water quality measurements were also done on 5 sampling stations <br />and the values obtained are shown in table 2.04.7(1)-2. <br />On seven instances the water from TP-W1 exceeds EPA domestic <br />water standards (EPA, 1976). These are shown in the following <br />table: <br />Table 2.04.7(1)-4.

The roof <br />and floor sample analyses (table 2.04.7(1)-5) do not show <br />exceptionally high contents of barium. The most conspicuously <br />high values in the above table are those of iron. Iron is also <br />high in the roof and floor strata (table 2.04.7(1)-5) and it may <br />be assumed that the rocks are the source of the high iron in the <br />water. <br />-In addition to iron, table 2.04.7(1)-5 shove anomalous values <br />for mercury, cadmium, copper, lead, manganese, nickel and zinc, <br />while molybdenum has borderline values. It is common to find <br />that ground waters high in fluoride are also high in pH (Hem, <br />1970). Fluoride and pH values for the roof and floor material in <br />TP-W1 appear to follow this pattern as well. The higher pH in <br />the overburden strata also agrees with its relatively lower <br />sulfur and carbonate - bicarbonate content as compared with that <br />of the floor. The difference in sulfur content between the two <br /> <br />JFSA-40
