To evaluate the risk of cancer from multiple chemicals detected in groundwater, a cancer health risk index must be calculated using the procedure specified in this part.
To evaluate the risk of cancer from multiple chemicals detected in groundwater, a cancer index must be calculated using the following equation:
Cancer health risk index=C1/cHRL1+C2/cHRL2+...+CN/cHRLN |
Where:
CN represents the concentration expressed as µg/L of the first through Nth chemical. In the case of a chemical that is detected but cannot be quantified, CN is determined by acceptable statistical procedures.
