A waste firm based in Dorset has been ordered to pay more than £40,000 for environmental offences.
Buckland Newton Hire ignored a warning from the Environment Agency to not store cesspit or chemical toilet waste and for not keeping proper records.
The company offered various services including ground works, plant hire, waste disposal, skip hire and haulage.
It had permission to store septic tank sludge at the farm but not cesspit or chemical toilet waste.
The Environment Agency’s officers found untreated cesspit and toilet waste at the site which they said can spread disease, pollute watercourses and infect the food chain if used on farmland as a soil improver and fertiliser.
It also found the firm failed to keep proper waste transfer notes which are accurate records of consignments of waste that companies have to provide.
Further checks of the site revealed a lack of adequate procedures and that staff working for the company was not properly trained.
An Environment Agency spokesperson said: “There have been longstanding problems at this site that lies within an Area of Outstanding Natural Beauty. Despite advice and support from the Agency, the operator failed to put the necessary measures in place and the business continued to be poorly managed.
“Illegal waste operators put human health at risk and can harm the environment. They also put legitimate businesses at a financial disadvantage.”
