Small and unsealed storage facilities were overflowing and there were large volumes of effluent ponded on paddocks from over irrigation. All of these discharges posed a significant risk of contaminating groundwater.
"This is a large fine and sends a very clear message," said council investigations manager, Patrick Lynch.
"A fine of $116,000, as well as the convictions for the company and director, has to be seen as a sign the court is losing patience with those remaining farmers who, quite simply, are causing environmental harm.
"In this case, the company owned five dairy farms and should have been setting an example as to how to do things correctly and sustainably," said Patrick.
"I am sure the rest of the dairy industry, as well as the wider community, who are working hard to improve the environment, are extremely disappointed with the farmer in this case, as he will be seen to be undoing the good work of so many."
