Maghull Labour Action Team has been working on getting a local grot spot cleared which they say could be dangerous to people in the community.
Sudell Ward Labour Councillors Patrick McKinley and Lynn Gatherer have called for the rubbish behind Central Square shops to be cleared up immediately.
Among the piles of rubbish are dangerous items, including an industrial battery.
Cllr McKinley said: "Cllr Gatherer, the Labour Action Team and I are very concerned by this rubbish, which has clearly been there for some time.
"It would appear to have been dumped illegally.
"We are concerned about the dumped rubbish's close proximity to houses and the shops, and the likelihood that it will attract rats and other vermin.
"And we have grave concerns about the type of rubbish which has been left. There's an industrial battery which in itself is a danger. these batteries contain hazardous chemicals which can do people serious harm."
Cllr Gatherer said the team has requested that the rubbish be cleared and an investigation carried out to find out who was responsible.
Cllr Gatherer said: "We have asked for the rubbish to be cleared away as a matter of urgency.
"There is a real danger to the public because of this rubbish.
"I am particularly concerned about children and young people climbing through the rubbish and coming to harm.
"As well as asking for the site to be cleared, we are asking for those responsible to be more considerate. Dumping rubbish is a health and safety issue. If you are caught, then the authorities will take action against you.
"There are facilities available in Sefton for rubbish of this kind to be disposed of legally and safely. If you aren't prepared to use those facilities, then you are breaking the law and the penalties can be, and should be, quite severe."
