Basic Features of Remediation Services

Remediation service providers are much in demand in the civil construction, mining and oil and natural gas sectors where clients require specialized services in order to manage their liabilities regarding contamination of natural environment, groundwater, soil or surrounding infrastructure. Specialized remediation services are required for site restoration in the contaminated areas as it involves expert management of sophisticated machineries, workers and community safety. Remediation also requires extensive planning so that the process is in compliance with national safety regulation.

Remediation of Contaminated Soil

This is commonly done to rectify environmental imbalances and to prevent the contaminants from seeping further into the soil and contaminating the groundwater. The technology was developed in the 1950s and is still used widely today to treat different types of industrial wastes and other contaminants. Remediation of contaminated soil reduces the need for creating more landfills and therefore helps in reclamation of land for better use. The process uses chemically reactive substances and other less harmful binding agents that solidify and form a stable layer on the contaminated soil. Common binders used are Portland cement, limestone, clay, slag, gypsum etc.

Both in situ and ex situ methods are followed for remediation of contaminated soil. In the in situ method, the binding agents are mixed into the contaminated soil at the site itself whereas in the ex situ method, the remediation is done at another site where the contaminants are excavated and removed to. The mixing is done there and the less contaminating material is then transported back to the original site.

Civil works contractors offer services for labour hire, project fencing, site clearing, road works, etc.
