A $32,000 attempt to fix problems with hard water in Attunga doesn't appear to have made much difference.

Residents noticed scaling in their kettles and soap scum rings in the bath in 2019 because of the high water hardness.
Tamworth Regional Council resolved in May last year to solve the problem with the installation of Magnetic Energised and Activated (MEA) devices.
But, a survey of residents shows there was no clear evidence the $32,000 investment had helped the water they previously said "leaves skin feeling itchy and dry" and a "large build up of calcium on all appliances."
Councillors received the report on Tuesday night, where similar issues with Nundle's water supply were identified and councillors discussed looking to that community next.
Five of the 50mm devices were installed on the main supply from the bores to the reservoir in Attunga so that all residents would receive water that had been treated.
Given the devices have already been installed and do not require power to operate, it will cost more to remove them.
For that reason the councillors decided on Tuesday that the devices will be left installed.
The water supply system in the town services 155 houses with an average consumption of 49.4 ML per year.
It is not a lot compared to an average of 15ML each week in Tamworth, Moonbi and Kootingal.
The hardness concentration in Attunga's bore water sits around 300mg per litre.
The Australian Drinking Water Guidelines limit aesthetic hardness to 200mg per litre, so while it won't affect consumers who drink it, it will affect the washing.

Water hardness is caused by high concentrations of calcium and magnesium ions in the water.
The average hardness of Tamworth's water sits at 151mg per litre, compared to Attunga's bores that have tested at up to 336mg per litre.
No further action will be taken in Attunga at this stage.
