LAST November, millions of tiny plastic pellets (nurdles) were dumped illegally into Warrnambool’s sewerage treatment system – polluting our beaches all the way from Thunder Point to Yambuk – and still nobody has been found responsible.

How can this be?

This was a criminal act, but as Bob Brown said recently, crimes against the environment don’t attract police cars with their lights flashing and sirens roaring.

It was also, I suspect, one of the largest pollution spills ever recorded in Warrnambool and one from which it will take months if not years to recover.

Even as I write this, the Good Will Nurdle Hunting action group – set up by film maker Colleen Hughson – and others, are still laboriously picking up thousands of nurdles to avoid them getting stuck in a seabird’s gut and killing them.

And yet five months on, Wannon Water, who is responsible for accepting and treating the waste that comes into the Warrnambool plant, appears no closer to finding a culprit.

In these days of swipe cards, security codes, security cameras, trade waste controls, random testing, checklists, computerised logistics and god knows what else, this seems inconceivable, but it is the current reality.

It is also astonishing that Wannon Water didn’t know exactly what was being poured into its treatment plant on or around November 16.

This might be a harsh assessment if we were talking about the general sewerage system that caters for tens of thousands of customers from across the south-west, including those stupid enough to flush all manner of junk down the loo.

But in this case, the search is not a needle-in-a-haystack scenario, but actually quite narrow.

BEAR with me for a second while I lay this out, because it is critical as to why this spill is considered by many to have been avoidable and why so many people are still angry and demanding answers.

Wannon Water has confirmed that the plastics came into its plant through what is called a Sludge Acceptance Point (SAP). This is where authorised tankers deliver gunk collected from authorised customers. You need a key and a swipe card to get in. In other words, it is not open to just anybody.

As Wannon Water managing director Andrew Jeffers said by email, “Wannon Water’s system is secure and only able to be accessed by approved customers. Volumes received at this point are only a very minor proportion of the total volume of sewage treated at the Warrnambool plant.”

Of these SAP customers, Wannon Water has identified 20 sites that were inspected as part of its investigation, including some sites that might use nurdles or raw plastic.

Yet despite nailing it down to just 20 likely sources, none of these inspections, it seems, has come to anything.

WANNON Water declined to list the 20 sites inspected, or to reveal much of anything about its ongoing investigation, so I asked five local, large industries directly if they had any knowledge of the spill.

Here is what they said:

Midfield Meats: “Midfield doesn’t use nurdles in any processes.”

Murray Goulburn: ‘MG does not use Wannon Water for its effluent disposal. We have our own wastewater treatment system and spray irrigate on to our farmland. In addition, MG does not use a product of this nature in any aspect of its manufacturing.’

Beach Energy: (owners and operators of the Port Campbell gas field, formerly operated by Origin Energy): “No nurdles are used in production on site.”

Fonterra: “I’ve spoken to our site environment manager and can advise that we don’t use nurdles in our production processes”.

Saputo/Warrnambool Cheese and Butter: The questions have been sent to Saputo communications in Canada – still waiting a response.

And what about two of Warrnambool’s septic and trade waste collection services, Berminghams and Sergeants? What do they know?

Sergeants: “As the records would state (we) didn’t dispose of any liquid waste at the Warrnambool facility during the months of October, November or December”.

Berminghams: “We have nothing to tell you about that.” The person said on the end of the phone before ending the call.

Lastly, I called Bartlett’s Environmental in Geelong.

Bartlett’s are contracted to clean the Wannon Water sewer pump stations and truck the sludge to the SAP, so maybe they unknowingly sucked up a load of nurdles around November 16 last year?

At first Barlett’s offered to look into it, and then, a day later, its general manager John McCoy emailed: “For all matters regarding contract work undertaken by Bartlett’s Environmental for Wannon Water, please refer all questions directly to Wannon Water.”

Mr Jeffers, who declined to be interviewed directly for this piece, said via email that Wannon Water had since ruled out the plastics coming in via sludge from a sewer pump station.

So around and around and around we go.

WANNON Water appears keen to find out who has caused it such grief.

It is even using the skills of a private investigator, retired police officer Mick Fennessy, who is a big, no-bullshit kind of guy, to try and flush out the truth.

But what this spill has exposed is not only an environmental vandal in action, but a gaping hole in how the Warrnambool treatment plant has operated – quite legally – to date.

Wannon Water has now realised that its screening systems were not good enough, both before sludge was poured into its plant, and once it passed through.

What has happened since this spill is that two, finer screens have been installed at the treatment plant to catch anything larger than 1.5mm before it reaches the ocean.

Wannon Water is also “now supervising all loads coming in” to the SAP, according to Mr Jeffers.

Both of these are important changes but, some argue, they should have been made immediately when thousands of cotton bud sticks appeared at Shelly Beach en masse in 2015 and turned up in vast numbers again last August.

The slim white sticks were considered to be the canary in the coal mine, sending a highly visual warning that thousands of litres of small plastic could be passing through the Warrnambool treatment plant to the ocean.

Nothing, however, was done, despite Wannon Water being told about the pollution.

“Both the Environmental Protection Authority and Wannon Water were informed by myself and others of the sticks, but they either didn’t believe me or were unwilling to do anything about it,” said Luke Foster, a local plumber and member of Good Will Nurdle Hunting.

If the new 1.5mm screen had been installed before November 16 last year, the argument goes, very few of the millions of dumped nurdles would have made it to the ocean.

“I am happy there is now a 1.5mm screen at the end of the waste water treatment plant to capture these plastics. However, it may be a long time before we are able to remove the majority of plastics that remain in the marine environment from past pollution,” Mr Foster said.

Mr Jeffers, however, has distanced Wannon Water from any responsibility for the cotton bud sticks.

“Wannon Water does not believe the cotton buds were related to the current sewage treatment plant nor the nurdle incident,” he wrote.

THERE is a lot at stake for Wannon Water from this pollution problem, with the EPA continuing its own investigation into potential breaches of the Environment Protection Act by the treatment plant.

As EPA South West manager Carolyn Francis outlined, the maximum penalty through the courts for a breach of an EPA licence is $380,568. The EPA can also directly issue Infringement Notices of $7729.

There is also, of course, the need to reassure the public that Wannon Water is top of its game when it comes to handling pollutants: preventing them from entering the system in the first place and catching them – and the polluters – when they do.

Catching the nurdle culprit so long after the event, however, appears increasingly unlikely and yet time alone, surely, cannot be an excuse to give up the search. We deserve answers.

In the meantime, Colleen Hughson, who really got the ball rolling on the public clean-up, says she has been amazed by the community response.

“The most heartening thing about the nurdles spill is the amount of ‘good will’ the community has shown in coming together to clean the mess up.

“(It) has also highlighted the bigger issue of marine plastic pollution and many people in my community have been inspired to look into ways of curbing their own consumer habits to stop the flow of plastic waste. It’s brought about conversations, generosity and a willingness to take positive action.”

  1. Your article asks questions many concerned people wanted answers to Carol however the answers to them from the relevant authorities raise even more suspicions that is there are cover up here?
    Thanks for the read and like a number of residents who care for their environment and regularly participate in collecting nurdles from our beaches, thank you for your article.

  2. Wannon water infrastructure of now installing the finer screen seems to be too little too late – for the amount of $$$$$$$being charged by Wannon water for services of sewerage and water you think they would have been better prepared for something of this proportion
    Too little too late
