Importance of Soil TestingAs we’ve already covered, soil testing before breaking ground on a new construction project is required by law in the State of California. This is because common soil hazards including lead, asbestos, Volatile Organic Compounds (VOCs), and chemicals including PCE and TCE often leech into the soil, polluting the dirt on a job site. To be clear, chemicals of any amount in the soil are never good for human health. However, construction often uncovers chemicals in the soil, exacerbating the previously unknown effects of soil contamination, creating even worse conditions for human health.
Importance of Ongoing Soil ManagementIf you think your job is done after initial soil testing and remediation, think again. Once your initial testing is complete, it’s crucial to employ ongoing soil management practices to ensure that your soil remains clean. Ongoing soil management can include the following:
- Complying with hazardous waste cleanup regulations following the initial soil test.
- Re-testing your soil if there is suspicion that it might be contaminated again.
- Working with an environmental professional to develop a soil management plan that suits both your needs and the needs of applicable regulatory agencies.
Types of Hazards Commonly Found in SoilAs previously mentioned, soil hazards can come in many different forms. It’s best for your project timeline and budget to test for soil hazards well before breaking ground on the project (six months before breaking ground is recommended), as waiting to characterize and dispose of contaminated soil can delay the project. Anyone involved in the industry knows that delays equal unplanned expenses. The chart below lists a few chemicals commonly found in the soil and their health risks.
- Lead: It’s well known that lead has adverse health effects in children, including a wide variety of developmental risks. Brain damage, for instance, is one common effect lead can pose on a child exposed to it. This article by the WHO further details lead exposure in children.
- Asbestos: In the past, asbestos was commonly used in commercial products, including insulation, fireproofing materials, and textile products. Today, asbestos can be found in insulation during construction, and naturally occurring in soil. When one is exposed to asbestos for long enough, he or she is at risk for asbestosis, lung cancer and mesothelioma.
- VOCs: VOCs, or volatile organic compounds, are toxic gases emitted from specific liquids. Usually, VOCs are emitted from common products, including paints, solvents, fuels, and cleaning products. Common VOCs found in soil are TCE and PCE, known commercial degreasing agents. TCE and PCE have been known to cause developmental effects in children, detailed in the Woburn, Massachusetts case that caused a leukemia cluster between 1969 and 1986.
