Remediation – Cleanup or other methods used to remove or contain a toxic spill or hazardous materials from a site. Stabilization – Conversion of the active organic matter in sludge into inert, harmless material.

Helical piles are ideal in areas of limited access, such as areas with low overhead or width restrictions.  Installation is unaffected by weather or high water table.  No vibration during installation means no damage to sensitive structures or instrumentation in the construction zone. The term Helical Piers, Screw Piles and Helical Piles are all used interchangeably.

Biosurfactants are surface-active substances synthesized by living cells. They have the properties of reducing surface tension, stabilizing emulsions, promoting foaming and are generally non-toxic and biodegradable. Biosurfactants enhance the emulsification of hydrocarbons, have the potential to solubilize hydrocarbon contaminants and increase their availability for microbial degradation. The use of chemicals for the treatment of a hydrocarbon polluted site may contaminate the environment with their by-products, whereas biosurfactant treatment may efficiently destroy pollutants, while being biodegradable themselves.

Hazardous materials are solids, liquids, or gases that can harm people, other living organisms, property, or the environment.
Field Testing is an experiment, research, or trial conducted under actual use conditions, instead of under controlled conditions in a laboratory.

Completely tearing down buildings, razing them to the ground and removing the debris to a landfill or waste treatment facility.

Procedures to control fiber release from asbestos-containing materials in a building or to remove them entirely, including removal, encapsulation, repair, enclosure, encasement, and operations and maintenance programs.

The term heavy metal refers to a group of toxic metals including arsenic, chromium, copper, lead, mercury, silver, and zinc. Heavy metals often are present at industrial sites at which operations have included battery recycling and metal plating.

The Resource Conservation and Recovery Act, or RCRA, is a law that addresses the safe and environmentally responsible management of hazardous waste in the United States. The Environmental Protection Agency (EPA), which oversees RCRA compliance, defines waste as hazardous if it meets certain criteria. To qualify as hazardous or RCRA waste, a substance must first be a solid waste. It must then fit the EPA’s definition of a “listed” or “characteristic” waste. Stabilization – Conversion of the active organic matter in sludge into inert, harmless material.

In-Situ – In its original place; unmoved unexcavated; remaining at the site or in the subsurface.

Chlorinated Solvent – An organic solvent containing chlorine atoms (e.g., methylene chloride and 1,1,1-trichloromethane). Uses of chlorinated solvents are aerosol spray containers, in highway paint, and dry cleaning fluids.

Technology that oxidizes contaminants dissolved in ground water, converting them into insoluble compounds.
