Site Characterization, Remedial Investigation and Feasibility Studies
Investigating the type, concentration, and extent of contaminations
AVENV can assist clientele in site characterization, to determine potential contamination. This includes investigating the type, concentration, and extent of the contamination, as well as studying the feasibility and cost of alternative remedial measures. AVENV staff can provide cost- effective approaches and detailed evaluations of various remedial options. This allows clients to choose the best approach for their business needs. AVENV is qualified to provide remedial recommendations on asbestos containing materials (ACM), lead-based paint (LBP), mold, polychlorinated biphenyl (PCB) contamination, soil contamination and other pertinent areas related to industrial hygiene.
Site Characterization – This is a preliminary process to determine the potential contamination of a site. Typically, a site investigation/facility characterization includes evaluating media and structure to access the extent of contamination. During an investigation, AVENV collects samples from the site, submits them to a laboratory for analyses, and interprets the laboratory data in order to make recommendations for exposure monitoring, remediation and clean-up.
Remedial Investigations – Should contaminants be discovered on-site, AVENV consults will perform a remedial investigation to determine the nature, extent, and environmental/health impacts of the contamination. This typically involves more detailed and comprehensive examination of the site, further characterization of contaminants, and documentation of the investigation.
Feasibility Study – Using information developed in the remedial investigation, AVENV scientists can draft a feasibility study. This study involves the identification and evaluation of alternative remedial technologies, as well as detailed cost analyses regarding remedial alternatives. Feasibility studies also involve the development of a preliminary remedial design. AVENV can also perform on-site testing, as needed, to assist in the preliminary design and cost estimation of these remedial approaches.
Remediation – AVENV performs the technical oversight and documentation for on-site remedial projects. Staff monitor the use of heavy equipment and provide waste management assistance, as needed. AVENV also conducts periodic sampling of contaminants, in order to monitor the remediation process and offer further assistance to clientele.

Industrial Hygiene Services
AVENV performs Industrial Hygiene services, including asbestos inspections, project design, project oversight, quality control, and air monitoring. Industrial Hygienist with AVENV successfully participate in the Proficiency Analysis Test (PAT) rounds, and are certified by the American Industrial Hygienist Association (AIHA). AVENV’s environmental Industrial Hygienist’s evaluate indoor air quality and assist in occupational exposure assessments to ensure a healthy working environment.
Exposure Monitoring and Assessments
AVENV Industrial Hygienist’s can conduct exposure monitoring for a broad spectrum of Occupational Safety and Health Administration (OSHA) regulated contaminants. These include dusts, fumes, mists, particulates, vapors and bio-aerosols. AVENV’s staff is trained to conduct lead, arsenic and silica exposure assessments. These are required under the OSHA Standard for Construction, in order to determine potential exposure levels to employees.
Indoor Air Quality Assessments
AVENV has extensive experience with indoor air quality or “sick building” assessments. These assessments include site reconnaissance to evaluate chemical usage, analysis of Heating, Ventilation and Air Conditioning (HVAC) systems and review of facility work practices. Direct read instrumentation is utilized to monitor common indicators of indoor air quality problems.
Construction and Demolition Project Management
AVENV and its team of professionals have extensive experience with construction and demolition project management. Projects related to this field of expertise include Environmental Site Assessments (ESAs), remediation, emergency response and structure demolition. From simple residential inspections to more complex projects involving the remediation and demolition of large commercial sites, AVENV can meet the growing needs of its clients in an efficient and cost- effective manner.
Cost Projection and Feasibility
AVENV staff has experience with construction cost evaluations, project design/feasibility and value engineering. From specification designs, to bid evaluations, to contract administration, construction inspections, and technical oversight, AVENV’s environmental specialists deliver comprehensive expertise.
ASTM Transaction Screen Process
AVENV performs Transaction Screen Processes, based upon standards established by the American Society for Testing and Materials (ASTM). Through this process, AVENV inquires as to the potential environmental liability associated with a specific property.
ASTM Phase I ESAs
AVENV’s team performs Phase I ESAs, in accordance with ASTM Standard E 1527-98 (ASTM-ESA). These assessments include a physical review of the site, investigations of past and present usage, and identification of previous and existing on-site structures and owners. AVENV staff also review documentation (i.e.) aerial photographs, street directories, historical documentation, government records, etc.), evaluate site characteristics, assess adjacent properties, and draft a written report that incorporates all information obtained during the Phase I ESA. This report communicates hazardous materials of concern on and adjacent to the site (such as asbestos, polychlorinated biphenyls (PCB), and underground storage tanks), as well as the potential for other environmental concerns.
AVENV provides oversight on projects involving the removal and off-site treatment and disposal of hazardous or contaminated materials. This includes oversight on the removal of asbestos, the excavation, transportation and disposal of contaminated soil, and re-containerizing drums.
AVENV has experience in a variety of environmental remediation, demolition and flood damage activities. These include, but are not limited to, the Federal Emergency Management Agency’s (FEMA) 403 Eminent Threat Program, the FEMA 404 Hazard Mitigation Grant Program, the Community Development Block Grant Program (CDBG), the FEMA 325 Public Disaster Assistance Debris Management Guide, the FEMA 19 Point Checklist, historic renovations, and flood-affected structures requiring comprehensive parcel documentation and resolution.
Debris Monitoring Services
AVENV staff has experience with debris monitoring activities. These include monitoring asbestos waste, household hazardous wastes (HHWs) and general demolition debris. AVENV technicians have established protocols for the identification and documentation of all debris generated during remediation and demolition activities.
Health & Safety
AVENV staff is knowledgeable with OSHA 29 Code of Federal Regulations (CFR) 1910.120 and 1926 and can certify that projects comply with the applicable requirements. Personnel are trained in such areas as: lead-based paint/risk assessment, asbestos building inspections, certified hazardous material management (CHMM) and other industrial hygiene areas.
