❓ Hon. Alison Xamon questions the Health portfolio regarding the monitoring of specific chemicals (glyphosate, DEET, Triclocarban, salicylic acid) in the Beenyup Managed Aquifer Recharge trial and the protocols for managing their levels, as well as the frequency and triggers for emerging chemical risk reviews.

QuestionView source ↗
I refer to the groundwater replenishment trials at Beenyup, and ask -
(1) Are levels of glyphosate in wastewater monitored for the Beenyup Managed Aquifer Recharge treated wastewater trial?
(2) If yes to (1), what levels of glyphosate have been determined to trigger management responses for treated wastewater reinjection into the Leederville aquifer?
(3) If no to (1), why not?
(4) What method for monitoring glyphosate has been developed?
(5) What are the current reporting levels for glyphosate required under the Australian Drinking Water Guidelines?
(6) Are levels of N.N-diethyl-m-toluamide (DEET) in wastewater monitored for the Beenyup Managed Aquifer Recharge treated wastewater trial?
(7) If yes to (6), what levels of DEET have been determined to trigger management responses for treated wastewater reinjection into the Leederville aquifer?
(8) If no to (6), why not?
(9) What method for monitoring DEET has been developed?
(10) What are the current reporting levels for DEET required under the Australian Drinking Water Guidelines?
(11) Are levels of Triclocarban in wastewater monitored for the Beenyup Managed Aquifer Recharge treated wastewater trial?
(12) If yes to (11), what levels of Triclocarban have been determined to trigger management responses for treated wastewater reinjection into the Leederville aquifer?
(13) If no to (11), why not?
(14) What method for monitoring Triclocarban has been developed?
(15) What are the current reporting levels for Triclocarban required under the Australian Drinking Water Guidelines?
(16) Are levels of salicylic acid in wastewater monitored for the Beenyup Managed Aquifer Recharge treated wastewater trial?
(17) If yes to (16), what levels of salicylic acid have been determined to trigger management responses for treated wastewater reinjection into the Leederville aquifer?
(18) If no to (16), why not?
(19) What method for monitoring salicylic acid has been developed?
(20) What are the current reporting levels for salicylic acid required under the Australian Drinking Water Guidelines?
(21) How often will regular emerging chemical and environmental risk reviews be undertaken during the groundwater replenishment trial?
(22) Will regular emerging chemical and environmental risk reviews be triggered by institutional approval for use of new chemicals, such as pesticides and pharmaceuticals; improved knowledge of hazards of known chemicals; and precautionary community concern for interaction between chemicals of concern?
