The issue was debated Monday night at the council's meeting, with concerns mounting from residents and local officials alike.
Sections of the Horace Williams tract have held hazardous waste material for the University since 1973. Now, town and UNC officials are at odds as to how immediate the need is to clean it up.
Chapel Hill Mayor Kevin Foy said he envisions it taking at least 12 to 16 months to secure funding for the endeavor.
"If you look at the steps that need to be taken ... it's going to take some amount of time to secure the funding," Foy said.
Once this preliminary step is completed, he said, preparation must be made to decontaminate the site.
"It seems like it's going to be a very tedious and time-consuming job," Foy said.
He said he would like to see the University develop a timetable for the project in the near future and added that the procedure will be quicker if the town and University collaborate.
Foy said the town is willing to participate in remediation of the hazardous material at the site.
He said that although town residents have been aware of the dump since 1973, recent development and other factors have threatened the area with contaminants leaching through the soil.
