What is Lead Contaminated Soil?

Lead contaminated soil refers to soil that contains an elevated concentration of lead, a toxic heavy metal. Lead contamination in soil can occur due to various human activities and natural processes.

TDJ Group has the knowledge and expertise to aid in the treatment and disposal of lead contaminated soil. We offer a simple solution for treatment of such wastes to prevent leaching called Blastox 215. Some common sources of lead contamination in soil include:

Historical Land Use

Soil can become contaminated with lead through historical land uses, such as industrial activities, mining, smelting, and the disposal of lead-containing waste materials.

Lead-Based Paint

Lead-based paints were commonly used in homes and buildings before the 1970s. As these paints deteriorate, they can release lead dust and chips into the soil around structures.

Battery Recycling

Improper disposal of lead-acid batteries, such as car batteries, can result in lead contamination of soil in the vicinity of recycling facilities or landfills.

Agricultural Practices

The use of lead-based pesticides or fertilizers in agriculture, as well as the disposal of lead-containing agricultural equipment, can contribute to lead contamination in agricultural soils.

Treatment of Lead Contaminated Soil

Efforts to remediate lead contaminated soil involve measures to reduce lead exposure risk, as discussed in the previous response. These measures can include soil testing, excavation and removal, soil stabilization, and other remediation techniques to reduce the mobility and bioavailability of lead in the soil.

If the contamination levels are moderate and the metals can be treated, consider remediation options. Common treatment methods include soil washing, or stabilization of lead contaminated soil. Stabilization is a simple solution for treatment of such wastes to prevent leaching using a product called Blastox 215.

Landfill Disposal

If the soil is heavily contaminated or treatment is not feasible, hazardous landfill disposal may be the most suitable option but very expensive. Using Blastox 215 allows prevention of metal leaching into the ground water. This will allow for local non hazardous disposal saving large amounts of money on the back end.

Disposal Services

Engage licensed waste disposal companies experienced in handling hazardous materials, including contaminated soil. They can assist with transportation, treatment (if applicable), and disposal in accordance with regulations.

Commitment to Excellence

For more than 30 years, TDJ Group has assisted the metal casting industry (ferrous & non-ferrous), lead paint sandblasting, and soil remediation industries in the stabilization of heavy metal contaminated wastes. More than 1,000,000 tons of industrial wastes have been eliminated or safely stabilized using TDJ chemistries.

Our management & staff possess many technical degrees including PhDs, MBAs, MSs, BSs and CPAs. However, at TDJ Group, we never stop learning, which is why we have an on-going education program for our employees. This program provides continuing education units (CDUs) in specific areas of need and encourages various industry certifications.
