Note 1: If analytical method detection limit or concentration exceeds soil RSL Indicates constituent is not a groundwater COPC attributable to coal ash. Note 2: If no soil RSL Deg C = Degree Celsius Spec Cord = Specific Conductance DUP = Duplicate S.U. = Standard Unit ug/I = microgram per liter mg/I = milligrams per liter Temp = Temperature mV = millivolts umhos/cm = micro mhos per centimeter NE = Not established NTU = nephelometric turbidity unit < = concentration not detected at or above the reporting limit.
