In 1999 was applicated of zeolite in to soils contaminated with heavy metals after non controlled application of sewage sludge. The heavy metal contents , mainly lead and zinc, was very incresed. During 2000-2002 the soil samples was collected and analyzed on heavy metal contents. After zeolite application was increased pH, sorption capacity (CEC) and hydrolytical acid was decreased. The content of lead was decreased about 0,25-120,4 mg per kg and zinc 1,02-52 mg per kg at zeolite application. The decrease in cuprum content was observed, but fall in the content of nickel and chromium was insignificated.
