There may be one, two, or all three exposure calculations per e xposure scenario.CC is the aquatic concentration of concern. 4 This column displays concentration values for the 7Q10 streamflow, which is defined as the average daily streamflow of the sev en consecutive days of lowest flow within a ten year period.
