Chemical Fixation
Chemical Fixation is a process to treat soil contaminated with lead and other heavy metals.
Soil contaminated with heavy metals and heavy hydrocarbons can be treated using the chemical fixation process. A chemical agent added to the contaminated soil begins a reaction that will leave the contaminants virtually insoluble, preventing them from migrating out if the soil.
The chemical agents are first mixed with water into the contaminated soil, usually in a pugmill. Once the reaction has begun the mixture is evenly spread out on a lined cell and left for several days to complete the treatment.
When the process is complete and laboratory testing confirms the results, the chemical reaction has transformed the contaminated soil into non-hazardous material. In most cases chemical fixation is a cost-effective method of remediation because a high volume of contaminated soil can be treated in a relatively short period of time.
