HSEM applies logical, structured approaches that consider future use of the property, regulatory requirements, onsite and offsite risk assessment and other client-specific factors to select the most suitable remedial action. Our personnel have experience with a variety of available remediation technologies and in applying cost-effective and innovative techniques for soil and groundwater issues. Specific services include Remediation Planning, Remedial Option analysis and design, Project Management and Implementation.
HSEM staff has extensive experience implementing cost-effective engineering methods for properly remediation of contaminated soil. In developing alternative clean-up methods specific to our client's needs, HSEM considers all factors involved, including the type and extent of contamination, soil characteristics, planned future use of the site, and appropriate legislation. HSEM personnel have experience with the implementation of the following remedial methods:
Excavation and Disposal
Based on the volume of soil, type of contaminant, availability of space, time constraints, soil conditions and/or the disruption of businesses, excavation and disposal of contaminated soils may be the most practical and economical alternative available. Our project experience and knowledge of local landfill procedures allows for rapid profiling and disposal acceptance of contaminated materials.
Enhanced Bioremediation
HSEM affiliates have implemented several biofeasibility studies and in situ bioremediation (ISB) projects. During the biofeasibility studies, HSEM and it’s affiliates evaluate the natural or indigenous microbial populations to cleanup the contaminated soil and groundwater. Alternatively, HSEM evaluates specific “degraders” that can be used to accelerate soil and groundwater cleanup. Bioremediation applications include both chlorinated solvents and typical petroleum hydrocarbons.
Soil Vapor Extraction
Soil vapor extraction (SVE) may be applied where volatile organic compounds (VOCs) occur in permeable soil. The method used is typically dictated by economics and the contaminant type.
Groundwater Remediation
HSEM has the ability to evaluate, install, operate, monitor, design and maintain a site-specific groundwater remediation system. HSEM’s staff has experience with water treatment systems using air stripping, carbon adsorption, hydrocarbon recovery, mechanical or gravity separation, biological treatment, and chemical treatment
