A CONSERVATION group has demanded that Kirklees Council tackle 10 grot spots in the area.
UK and Kirklees Friends of the Environment handed council environmental officers a list of the eyesores 15 days ago.
And the group claims nothing has been done since.
The two worst sites are allegedly at Grimescar Woods, off Old Halifax Road in Huddersfield, and Kilner Bank, near to the McAlpine Stadium.
The group says general litter is also creating an eyesore and health hazard in the River Holme at Holmfirth, at Chapel Hill, Milford Street in Huddersfield, and in an area behind Ravensthorpe train station.
Ian McCourtie, a director of UK and Kirklees Friends of the Environment, said: "At the other sites it is general litter, but at these two there are out-of-date rotting chickens, hypodermic needles and chemical drums.
"I can see it is a very difficult job for the council and I understand the problems. But it should be a priority for the council to clear hazardous things like this up."
Tipping sites at Bradley Mills Road in Huddersfield, the junction of New Hey Road and Pinfold Lane, Rastrick and at Sands Road, Earlsheaton, have also been branded unsightly.
Mr McCourtie said his group was thinking of legal action if the council did not clean up the problem sites. He said: "Nothing has been done. We are going to give it a week, then we will take action."
A council spokesman said workers had acted although the legislation quoted by the group did not apply to all the areas.
"Sites already dealt with are Chapel Hill near the electricity substation, Sands Road at Earlsheaton and Milford Street," he said.
"The gullies at Huddersfield Town Hall are a problem as they are completely inaccessible.
New Hey Road at Rastrick is in Calderdale, not Kirklees. All the rest of the sites have been inspected and land-owners are being traced in order for waste to be removed."
