(2) If yes to (1), -
(a) what levels of NDMA N-Nitrosamines will trigger greater levels of analysis and monitoring; and
(b) what management measures are in place to monitor, mitigate and prevent NDMA N-Nitrosamines in excess of Australian Drinking Water Guidelines being reinjected into the Leederville aquifer?
(3) What method for monitoring NDMA N-Nitrosamines has been developed?
(4) What are the current reporting levels for NDMA N-Nitrosamines required under the Australian Drinking Water Guidelines?
