Abstract

LEAD IN SOIL MUST BE TREATED IN ORDER TO REDUCE THE EXPOSURE RISK ASSOCIATED WITH LEAD MIGRATION AND LEAD BIOAVAILABILITY. SINCE THE LEVEL OF LEAD IN CONTAMINATED SOIL IS USUALLY VERY LOW, A COST-EFFECTIVE AND SAFE LEAD FIXATION TECHNOLOGY IS NEEDED. THIS RESEARCH WILL INVESTIGATE A NOVEL LEAD FIXATION TECHNOLOGY BASED ON NATURAL SOIL CHEMICAL REACTIONS WITH ENVIRONMENTALLY SAFE MATERIALS. PHASE I WILL DEMONSTRATE THE EFFECT OF SOIL IMPREGNATION AND LEAD FIXATION. PHASE II WILL DEVELOP COMMERCIAL MATERIALS AND ENGINEERING PRACTICES FOR FIXATION OF CONTAMINATED SOILS AND REDUCE LEAD LEACHABILITY IN THESE SOILS.
