(7) ACTEW informs me that turbidity increases in the raw water supply from Bendora reservoir are of concern. I am advised that since the bushfire in the Cotter catchment in January 2003, there have been several occasions when storm events have increased the turbidity of the supply from this reservoir. On these occasions ACTEW supplied water from the Googong reservoir, which is fully treated. ACTEW advises that the supply from Googong reservoir will always have a low turbidity level as the supply is filtered.
(8) I am advised that this is a matter for ACT Health as ACTEW does not keep such records.
(9) ACTEW advises me that it informs ACT Health of any incidents under the Drinking Water Quality Code of Practice. Public notification is a matter for ACT Health.
(10) I am advised by ACTEW that it informs ACT Health of any significant variations in turbidity levels beyond those outlined in the Drinking Water Quality Code of Practice. Public notification is a matter for ACT Health.

(2) How many complaints has the Government received regarding a problem with smell or taste of water;
(3) What water testing does the Government conduct to monitor the safety and potability of the water supply;
