Frustration is growing in Tasmania’s east coast town of Scamander over water quality issues.

Scamander, on the heavily promoted Great Eastern Drive, has a population of about 500 but that triples with tourists during summer.

During peak demand the water treatment plant cannot cope and could carry dangerous contaminants.

There has been a temporary boil water alert in place for about 10 years but that has recently been upgraded to a permanent alert.

Residents and business owners have had enough, and are stepping up their campaign to have the water supply fixed.

Shack owner Jim Rudling wants answers.

“Whilst I understand that there can be issues in relation to water quality at times, for it to go on over 10 years, you get to a point where it just becomes pure frustration,” he said.

Resident Pam Bretz said it was bad for the town’s image.

“To have to tell people they have to buy water to drink is a shocking thing, this is clean green Tasmania and I think we should be able to drink the water,” she said.

Tourism is suffering, operators say

Accommodation owner Maureen Gill said it was not good enough.

“This is a first-world country and people expect when they travel in a first-world country to be able to drink water and they’re quite horrified when they arrive here and find that they can’t,” she said.

“It’s pristine, it’s clean but the water’s not and it’s just something people are very surprised to find.”

Local hotel operator Brian Forsyth is concerned about the effect it is having on tourism.

“Everybody’s got to have water for something and that comes back to where do we go, why stay here when we’ve got to buy water, when we’ve got to boil water, when we can go up the road to St Helens 15 kilometres, go 50 kilometres down the road to Bicheno,” he said.

“A lot of people will take those choices.”

It is also an extra cost to business owners who supply bottled water to guests.

System upgrades a ‘priority’

TasWater’s Lances Stapleton said they were planning an upgrade and hoped to have the alert lifted by next year

“We have a big range of investments in terms of removing boil water alerts from around the state,” he said.

“Scamander’s been given some priority now so we’re starting the project in the next six to eight weeks.”

Break O’Day Mayor Mick Tucker was optimistic.

“It’s not good enough for anybody no matter where you live and we all accept that but TasWater are in control of that and they’re working hard to try to get funding to try and get on and fix the job,” he said.

But Ms Gill was not convinced.

“It’s the same as what we’ve been told before and all of those promissory dates have come and gone,” she said.

In the meantime Mr Forsyth is taking direct action.

“We are withholding our bill to TasWater, you cannot refuse to pay it but we are withholding it until the water supply is correct,” he said.

Residents want a town meeting with TasWater.

Scamander  (Tasmania) – Chloroketones 

27/8/24: Scamander (Tasmania): 1,1,1-trichloropropanone 1.9 ug/L

Data are inadequate to set guideline values for chloroketones in drinking water. GENERAL DESCRIPTION The chloroketones are produced in drinking water as by-products of the reaction between naturally occurring organic matter and chlorine. No data are available on other sources or uses for these compounds. Concentrations of chloroketones in drinking water reported overseas are very low and are estimated at less than 0.01 mg/L.

TYPICAL VALUES IN AUSTRALIAN DRINKING WATER In major Australian reticulated supplies 1,1,1-trichloropropanone has been recorded in concentrations up to 0.02 mg/L, but it is usually below the limit of determination of 0.0005 mg/L. No data are available for other chloroketones.

LIMITING FORMATION IN DRINKING WATER The presence of chloroketones in drinking water can be minimised by removing naturally occurring organic matter from the source water, by reducing the amount of chlorine added, or by the use of alternative disinfectants.” 2011 ADWG

Scamander (Tasmania) – Haloacetonitriles 

27/8/24: Scamander (Tasmania) Bromochloroacetonitrile 1.2ug/L Dichloroacetonitrile 1.3ug/L

“GUIDELINE
Data are inadequate to set guideline values for haloacetonitriles in drinking water
GENERAL DESCRIPTION
Haloacetonitriles are formed from organic precursors during chlorination or chloramination of drinking  water. Concentrations of dihaloacetonitriles reported overseas range up to 0.04 mg/L but are typically  less than 0.003 mg/L. Concentrations of trichloroacetonitrile are less than 0.001 mg/L.
Trichloroacetonitrile has been used as an insecticide. No data are available on uses for the other haloacetonitriles.

GUIDELINE

“No guideline is set due to the impracticality of controlling water temperature.
Drinking water temperatures above 20°C may result in an increase in the number of
complaints.

Temperature is primarily an aesthetic criterion for drinking water. Generally, cool water is more palatable than warm or cold water. In general, consumers will react to a change in water temperature. Complaints are most frequent when the temperature suddenly increases.

The turbidity and colour of filtered water may be indirectly affected by temperature, as low water temperatures tend to decrease the efficiency of water treatment processes by, for instance, affecting floc formation rates and sedimentation efficiency.

Chemical reaction rates increase with temperature, and this can lead to greater corrosion of pipes and fittings in closed systems. Scale formation in hard waters will also be greater at higher temperatures…

Water temperatures in major Australian reticulated supplies range from 10°C to 30°C. In some long, above-ground pipelines, water temperatures up to 45°C may be experienced…

The effectiveness of chlorine as a disinfectant is influenced by the temperature of the water being dosed. Generally higher temperatures result in more effective disinfection at a particular chlorine dose, but this may be counterbalanced by a more rapid loss of chlorine to the atmosphere (AWWA 1990).
