We are California MBE/DBE General Contractors with decades of experience in the management and remediation of HAZMAT, heavy metals, carcinogenic substances, hazardous waste, RCRA, contaminated soils, and VOCs (Volatile Organic Compounds). We are also experts in the new field of PFAS-laden soils and waterways.
We have a wider range of licenses than any contractor in the state, giving us experience over all scopes of work related to HAZMAT, acutely toxic environments, radioactive substances, earthwork and excavation, general engineering and hillside reinforcement, groundwater treatments, and more. This includes the rare AQMD-1166 Various Sites license for contaminated soil management across the state. We are the ONLY company licensed for all comprehensive solutions for all HAZMAT, Biohazard, heavy metals remediation and carcinogen mitigation services at all levels, be it Public Works, Federal/Tribal, police/DEA, commercial or residential.
In particular, we specialize in expert consultation for hydrocarbons, heavy metals (incl. lead, mercury, beryllium, chromium, mercury, arsenic, etc.), TPH, PAH, PFAS, Perchlorate (PERC), PCB-/Dioxin-contaminated soil, and Vinyl Chloride. We are also experienced with a variety of methods for VOC odor reduction (VOC Encapsulation), such as Posi-Shell spraying, solidification, dust palliative options, hydroseeding, and more.
Over the past several decades, California has increasingly regulated soil quality as a step towards development and construction. Depending on the level of contamination following soil testing, contaminated soil must either be treated in-situ with soil vapor extraction and other methods, or exported via manifest to a HAZMAT landfill. When these options pose a risk to produce leachate runoff and violate Water Board, AQMD, or DTSC permitting, soil stabilization is a critical step for contaminated soil management.
While these interventions are usually directed under permit by regulators, we have used a variety of options for soil stabilization ranging from mycoremediation, to bioencapsulation, to soil additives. We are also experts in PFAS soil remediation. Call the Mayfield HAZMAT team to make it happen.
Most often, soil stabilization involves injecting soil additives such as soda ash to bentonite clay to specialized soil selections that harden viscous soils. Mycoremediation involves us using mushroom mycelia substrates to contaminated soil to breakdown pollutants and stabilize loose soil. While this is experimental and largely unproven in the field, it has been most effective against heavy metals and more recently PFAS (Forever Chemicals). Bioencapsulation is another option we’ve used that involves injecting natural enzymes and organisms into the contaminated soil to slowly diminish hydrocarbon chains and recycle contaminated materials.
