Commercial property owners often face hidden environmental liabilities. Understanding the most prevalent types of soil contamination is the first step toward successful site remediation and safe redevelopment. Whether you are managing a former industrial site or a retail complex, identifying these pollutants early can save thousands in future cleanup costs.
Common Contaminants Found in Commercial Soil
Soil contamination rarely happens in isolation. Often, “historic fill”—soil brought in from other locations decades ago—contains a cocktail of hazardous materials. Here are the primary culprits found during environmental site assessments:
-
Petroleum Hydrocarbons (TPH/EPH): These usually leak from underground storage tanks (USTs) or old machinery.
-
Toxic Metals: Lead, arsenic, and mercury are common byproducts of industrial manufacturing.
-
Solvents and Industrial Chemicals: Dry cleaners and degreasing operations often leave behind volatile organic compounds (VOCs).
-
Polychlorinated Biphenyls (PCBs): These “forever chemicals” often originate from old electrical transformers.
-
Pesticides and Herbicides: Even urban commercial lots may have high concentrations if they were previously used for large-scale landscaping or agriculture.
How Remediation Companies Manage Contamination
Professional soil remediation companies do more than just dig. They follow a strict protocol to ensure safety and compliance with EPA soil screening standards.
-
Onsite Sampling: Technicians collect core samples to map the horizontal and vertical extent of the plumes.
-
Data Interpretation: Experts analyze the lab results to identify the specific types of soil contamination present.
-
Disposal Strategy: Based on the concentration of chemicals, the team determines if the soil requires hazardous waste disposal or if they can treat it onsite.
By identifying these risks early, developers can protect both their investment and the local ecosystem.
