Asbestos Surveys, Abatement Designs, and Abatement Inspection
Buildings built before 1981 are likely to have asbestos containing materials (ACM) in a variety of potential forms. EPA and OSHA have steadily tightened regulations pertaining to asbestos in renovations and demolitions, so many clients now recognize the need for qualified asbestos surveys in preparation for any such project. CDI has had EPA-certified asbestos building inspectors and abatement project designers on staff continuously since 1988, when EPA first required AHERA inspections of all school facilities.

In the intervening years, we have performed asbestos surveys throughout Alaska on facilities ranging from private dwellings slated for demolition to multi-million dollar hospital renovation and expansion projects.

In many cases, we have gone on to prepare asbestos abatement contract documents to support demolition projects and/or renovations, and then provided inspection services during abatement.

Our AHERA-certified asbestos inspectors and designers have close working relationships with municipalities and architects throughout Southeast Alaska, and we have worked with all the major abatement firms that are active in Alaska.

It is our goal to prepare documents that will result in trouble-free abatement jobs with the minimum number of change orders. We strive for fair value for our clients as well as for the abatement contractors.

Environmental Monitoring
CDI has a wide range of experience in developing and implementing sampling programs for a wide variety of projects. These can include:
  • Indoor air sampling for mold, dust, asbestos, or volatile organic compounds
  • Surface water and storm water sampling for parameters such as fecal coliform, turbidity, pH, or total suspended solids
  • Long-term groundwater monitoring for petroleum hydrocarbons or heavy metals

We will evaluate the problem and review the environmental regulations with you to develop a sampling program that will meet both your needs and those of the regulating agency.

Hazardous Materials Management
CDI can inspect your facility and determine whether there are any associated hazardous waste concerns. We can prepare waste profiles and manifests for the proper shipping and disposal of your hazardous and non-hazardous wastes including used oil, antifreeze, flammable liquids, paint-related materials, and corrosive liquids. CDI is the prime contractor for the Southeast Conference Household Hazardous Waste Collection Program serving 12 communities in Southeast Alaska and Prince William Sound.


Underground Storage Tank (UST) Assessment and Release Investigations
Over time, underground storage tanks can fail, particularly if the tank is in contact with groundwater or if the fill and return lines get damaged. CDI can provide rapid spill response in the event of a catastrophic loss, or CDI can conduct a site assessment to determine if the ground has been contaminated from a slow leak. We can develop clean-up plans for contaminated soil removal and disposal, and work with you and the regulators to get your site cleaned and approved.

Contaminated Site Characterization and Clean-Up
CDI has many years of experience identifying and addressing contamination in soil and groundwater at sites ranging from small, residential heating oil tank clean-ups, to CERCLA clean-ups on federal lands. Whether it’s initial site characterization, directing the clean-up effort, on-site soil remediation, groundwater monitoring or hazardous waste iidentification transport and disposal, CDI has the expertise as well as the
working relationships with regional clean-up contractors and waste shipping and disposal facilities to get the job done efficiently and in compliance with environmental regulations.

Health and Safety Plan Preparation
Government regulations require that most companies have a health and safety plan for their operations, as well as for environmental clean-up operations. CDI has developed Safety Site and Health Plans for a wide variety of projects and company safety programs.


Quality Assurance/Quality Control and Data Review
CDI provides third-party data review for quality assurance/quality control (QA/QC) purposes to assist clients in data validation. Our expertise is generally in water quality data review; however, we have a chemist on staff that can perform QA/QC reviews for a wide variety of data

Phase I and II Environmental Site Assessments
CDI routinely performs site assessments for property owners seeking to sell their property or for prospective buyers of a property. Our Phase I assessments include a thorough on-site inspection of the property, research into the property history, and a review of all available environmental information about the property and the surrounding area. Where potential sources of contamination are identified during the Phase I, we may recommend a Phase II assessment, which involves sampling and further investigation. For other property transfers we may conduct a more streamlined version of a Phase I Environmental Site Assessment, called a Transaction Screen Analysis.
