February 2019 – Menindee (New South Wales) – Blue Green Algae


We explore the link between NSW waterways and a toxin that might trigger MND.

Professor Dominic Rowe of Macquarie Neurology says, “From 1986 to 2016, there’s been a 250% increase in Motor Neurone Disease as a cause of death in Australia and that can only be environmental…”

Research overseas has linked the neurotoxin BMAA, a by-product of blue-green algae, to MND. This toxin was recently discovered in Lake Wyangan in NSW.

It’s also been found in a number of other drought-affected New South Wales waterways, including along the Darling River.

Professor Rowe says, “If we can understand what in the environment triggers Motor Neurone Disease, conceivably we could prevent [it] from even occurring.”

Tim Trembath, an MND sufferer, lives at Lake Cargelligo, which is 140-kilometers north of Griffith. He’s spent a lot of time at this lake, where there’s been an outbreak of blue-green algae.

Tim says, “Up until about 2010, the lake water was the water that was used for drinking and washing in the town.”

The disease has stripped Tim of his ability to ride his motorbike and he needs regular care. Two of his friends in the 1500-resident town have died from MND.

“Anyone who lives in this town has probably swum in the lake, and the lake has algal blooms in it nearly every summer.”

While it’s easy to assume there’s a link between these waterways and MND, Professor Rowe says, “It is highly unlikely that there’s going to be one specific environmental trigger, it’s likely to be a combination of factors.”

Menindee locals living with ‘disgusting’, ‘filthy’ tap water that smells like ‘a sewer’


If your tap water was the colour of mud, would you drink it?

Menindee locals in far-west New South Wales say that is what they are being forced to endure.

“This is the disgusting water coming out of our tap today,” Taya Biggs wrote in the Menindee Region Community Group on the Darling River Facebook group.

“They expect us to wash, drink, cook and wash our clothes in the filthy water.”

Another person wrote: “My bathroom water is green. Spewed in the shower again from the stench”.

The town has been in the headlines this week after a million fish were found dead along 40-kilometre stretch of the Darling River at Menindee, near Broken Hill, as a result of a toxic algal bloom.

Ms Biggs’s post has been shared almost 3,000 times.

Her mother Daphne Biggs said while they “don’t have any choice” but to shower in town water, they rely on rainwater for everything else although she expects that will only last another two months.

“The smell [of the tap water] is absolutely disgusting,” she said, adding that no-one in her house had drunk the water for two years.

Locals say water makes them sick

Life-long Menindee local Dorothy Stephens said the water — supplied by Essential Water — has made her sick.

“Right up until Christmas I was still boiling that water and drinking it and then I worked out I was getting diarrhoea from it, so we stopped,” she said.

She is not alone. Ngiyampaa elder Beryl Carmichael has lived in Menindee for 84 years.

“I drink rain water, otherwise I’d be running to the toilet,” she said.

Essential Water to blame says tourism body

President of the Menindee Tourism Association Rob Gregory said the water coming out of the taps was “pretty brown”.

“Prior to the first fish kill, our water had a smell to it which was sort of like a dammy, old, muddy smell that wasn’t too bad,” he said.

“But then straight after the first kill, it started to smell like sewer.”

He said he was “disappointed” with Essential Water.

“Even after the first kill, [they] didn’t even put a media release out to say that the water’s okay,” Mr Gregory said.

“We’re paying top dollar for that water and what are we getting? Second grade, third grade quality; it’s not good enough.”

Essential Water stands their ground

Despite locals’ concerns, Essential Water is defending the quality of water being supplied to the town.

“We’ve received only two water complaints of coloured water at Menindee,” head of operations John Coffey said.

He said both visits resulted in “minor flushing” and said water samples taken at the sites “complied with the requirements of the Australian Drinking Water guidelines”.

“So it was certainly an isolated incident,” Mr Coffey said.

He said Essential Water sourced water from the Darling River, Lake Copi Hollow, and the Menindee common bore.

Mr Coffey refused to say what triggered Essential Water’s water source switch from the Darling River to Lake Copi Hollow in December 2018.

“The choice of raw water supply to the Menindee Treatment Plant is based on raw water quality at the time,” he said.

He said anyone with complaints of poor water quality should contact Essential Water on 13 23 91.

Brown tap water across Western NSW deserves state of emergency response

By Roy Butler and Helen Dalton

The NSW Government must supply and distribute free bottled water across the growing number of rural towns unable to drink their tap water.

It’s only fair government step in to help those enduring third world living conditions, due to government draining of lakes and mismanagement of our river system.

Brown water crisis

The small town of Billmari, near Cowra, is one of several towns where potable water is too dangerous to drink.

Ironically, Billmari is an Aboriginal word meaning ‘plenty of water’.

Menindee now has plenty of brown water coming out of taps. Menindee is where locals begged governments not to drain their lake in 2017, because the lake supplies their drinking water. Governments ignored them.

Residents in Wilcannia, Hay, Cootamundra, Ganmain, Coolah and Yass have also reported foul-tasting tap water to us.

Walgett has faced such severe drinking water restrictions that generous Dubbo residents have supplied them with bottled water via a Facebook campaign.

But why are drought-stricken neighbouring towns carrying the can for the governments who caused this mess?

Last weekend, NSW Premier Gladys Berejiklian went to Coogee Beach. She pledged millions of dollars to clean the beach swimming water there.

It’s now time for Gladys to come out west to help those who can’t even drink the tap water.

State of emergency time

If an oil spill poisoned a river, killing one million fish and robbing towns of their drinking water, the NSW Government would declare a state of emergency.

This would force government agencies to get out to affected areas; and help the many residents who can’t afford expensive bottled water.

Under NSW state law, the Premier can call a state of emergency due to: fire, flood, storm, earthquake, explosion, accident, epidemic or warlike action which endangers people’s health.

This law needs to be changed, to include man-made disasters — like governments draining a town’s supply of drinking water during a drought —  in the list of emergencies.

There are several state government departments that administer water, employing thousands of bureaucrats.

Why not get them out to Menindee, Walgett, Billmari and other affected towns, to set up water hubs and to distribute free bottled water?

It’s the least the government could do.

Royal Commission next

We’ve both traveled to third world countries like Papua New Guinea, India and Cambodia. Not being able to drink the tap water was the biggest difference between those places and Australia.

That’s why it’s disgraceful we’ve let things come to this in our regional towns.

Clean drinking water should be the number one priority of any civilised nation, ranking well above Sydney stadiums and beaches.

This is why we urgently need a federal royal commission into how governments manage our rivers.

A royal commission will expose the government’s bad decisions on draining lakes; and flush out wealthy National Party donors who rort the system.

But Royal Commissions can take years, and we have a crisis now.

The state government needs to get cracking. It’s time for immediate state of emergency-style provision of free bottled water to towns like Menindee, Walgett and Billmari, where tap water is too dangerous to drink.

Motor neurone disease link to algae toxin exposure a developing path of research, scientists say

March 28 2019: https://www.abc.net.au/news/2019-03-28/scientists-say-link-between-algae-and-mnd-needs-further-look/10943826

Menindee resident John Brereton has a theory about what caused his wife, Pam, to develop motor neurone disease (MND), and it is a path that scientists are investigating.

Key points:

  • Research suggests toxin in blue-green algae blooms may increase neurological diseases
  • Incidence of MND in Griffith is seven times higher than the national average
  • CEO of MND NSW is not convinced of link between blue-green algae and MND

Up to 2,000 Australians are estimated to have MND, but diagnosis is painstakingly difficult because researchers are not yet sure how the disease is triggered.

“I couldn’t really say for certain, but I do believe the blue-green algae has got something to do with it,” Mr Brereton said.

Recent research, too, has pointed to environmental toxins such as those found in blue-green algae for a range of neurological diseases.

Ms Brereton grew up in Ballarat, near Lake Wendouree, which experiences algal blooms like many waterways in Australia.

John and Pam Brereton also lived in the Darling River town of Menindee for 19 years and used river water for cleaning and bathing, but drank filtered rainwater.

Menindee, in far-west NSW, was the scene of mass fish kills over summer, which the Department of Primary Industries said were caused partly due to blue-green algae.

“The algae has killed the fish. It’s killing everything, actually,” Mr Brereton said.

Fears in Menindee reflect those of people in Griffith in central NSW, where the incidence of MND is seven times higher than the national average, according to recent research.

The common link between the towns is proximity to a water source that is frequently beset by outbreaks of blue-green algae.

However, the CEO of the Motor Neurone Disease Association of NSW (MND NSW) Graham Opie is not convinced.

“There are so many theories. The fact is we just don’t know what causes or triggers MND,” he said.

Can BMAA cause motor neurone disease?

Blue-green algae, or cyanobacteria, are the oldest living organisms on the planet precisely because they are good at out-competing others by releasing toxins.

What’s known about link between BMAA and MND:

  • BMAA is a neurotoxin found in cyanobacteria, also known as blue-green algae
  • BMAA affects the neurological function of the brain by causing protein misfolding
  • Protein misfolding is a key characteristic of neurological disease
  • Scientists say while there is a link between BMAA and MND, more research is needed to determine the risk associated with exposure

One of these is the neurotoxin BMAA.

Dr Ken Rodgers from the Neurotoxin Research Group at the University of Technology Sydney specialises in environmental neurotoxins and how they interfere with the body’s functions.

“I think people should be worried. I get contacted regularly by people who have MND and have had obvious exposure to cyanobacteria,” Dr Rodgers said.


Cyanobacteria are always present in rivers and lakes, but only bloom into blue-green algae when conditions are favourable.

Low water flows, high temperatures, and nutrient build-up from agricultural run-off are all factors that contribute to algal blooms.

“I’m not trying to be alarmist,” Dr Rodgers said.

“Algal blooms are dangerous, but they’re being monitored by professionals so just follow the guidelines.”

Alerts issued by water authorities stipulate that people should not swim in, drink from, or eat seafood from algae-affected waterways.

Dr Rodgers said governments should be doing more than that to mitigate risk.

“You’ve got to try to take away the risk, even if it’s not going to affect everybody,” he said.

“Governments have got to start looking after the waterways, keep flows going, stop allowing big companies to dump chemicals into the waterways.”

More research needed

Mr Opie of MND NSW said there had been no recorded increase in its membership base in the far-west of NSW, an area struck by repeated blue-green algae events in its waterways.

“We’ve had fairly constant numbers, and those numbers haven’t changed in the 13 years I’ve been with the organisation,” he said.

Dr Rodgers said that just because toxins may be present in the water, it did not mean people exposed to blue-green algae would get sick.


“Someone who smokes from 16 to when they’re 100 years old doesn’t disprove that smoking causes cancer, it just shows that some people have resistance genes, and some have susceptibility genes,” he said.

“It’s the same story with exposure to environmental toxins.”

But he believed “there’s no question that BMAA can cause neurological disease”.

“The question is — how big is the risk and what makes you susceptible?” Dr Rodgers said.

He is calling on governments to invest more research dollars into the environmental factors that may trigger MND.

“What we’re trying to do is understand how the toxin affects us, and from there we could try to work out what the susceptibility genes might be,” he said.

Mr Brereton of Menindee said he believed he would never know exactly why his wife got sick, but hoped that some day the cause would become clear.

“She was a fit woman all her life, worked, never had any illnesses, and then all of a sudden — bang,” he said.

“I just hope that no-one has to put up with it. It’s a very cruel disease.”
