Notes:
Coal ash COPC (See Table 12-2)
Constituent determined to be a human health COPC potentially attributable to coal ash.
Constituent not determined to be a human health COPC potentially attributable to coal ash.
Hexavalent chromium (Cr`s) is a human health COPC but ash pore water data to date suggest that Cr" in groundwater is not attributable to coal ash (7-10).
NA = Not applicable
NE = Not evaluated
