Environmental Services

Arctic Data Services provides a wide range of environmental services in Alaska. We work diligently to achieve your objectives, throughout the site assessment, characterization, cleanup, and closure process. We offer extensive experience and technical expertise at very competitive rates. Being a small firm with low overhead, we are able to complete small projects much more efficiently than larger firms. With our dedication to client service, our experience working in northern and rural Alaska, and our strong working relationships with the Alaska Department of Environmental Conservation, we will help make your next project a success.

Spill Response and Cleanup


From home heating oil releases to tanker-truck rollovers, we work with our clients and emergency responders to minimize the negative repercussions and lasting impacts (both environmental and financial) of these tragic incidents. Our qualified environmental professionals have experience working with private clients, regulators, insurers, responders, and other stakeholders to coordinate quick, efficient, and effective cleanup operations. We maintain a teaming partnership with Anchorage firm Rescon Alaska to provide quick response times for all of Alaska’s roadways and rural villages. Our team has over four decades of combined experience in field management and remediation (including alternative soil treatment technologies such as phytoremediation), and excellent working relationships with the spill prevention and response division at the Alaska Department of Environmental Conservation. We bring unparalleled value, extremely competitive rates, and greater responsiveness and flexibility than larger firms.

Environmental Site Assessments


Looking to purchase commercial property?

In order to qualify for landowner liability protections under federal environmental law, you must exercise due diligence and conduct a Phase I environmental site assessment (ESA). Otherwise, you can be held responsible for cleanup of historic contamination, turning your new asset into a major liability.

We conduct Phase I ESAs for a wide variety of clients, with very affordable rates and quick turnaround times. With a lifetime of local experience in Fairbanks, Alaska, and nearly a decade of professional experience conducting ESAs, we have the knowledge and the expertise to make sure your pending purchase doesn’t come with an unexpected environmental liability. Our professionals are familiar with the particular challenges of conducting Phase I ESAs for rural properties, and work closely with rural communities on all aspects of our rural Phase I ESAs. We provide affordable ESA services in accordance with ASTM Standard E1527-13, meeting the EPA’s “All Appropriate Inquiries Rule” requirement for due diligence under CERCLA.

A Phase II ESA goes one step further to confirm the presence of environmental contamination and to evaluate the source, nature, and extent of contamination if present. We strive to collect sufficient field data at minimal cost to our clients. We tailor our assessments to your needs and appetite for risk. Unlike larger firms, we have a great deal of flexibility and responsiveness, even on smaller projects.

Groundwater Monitoring


We provide a full range of groundwater monitoring services, from initial assessment with temporary well points to monitoring well decommissioning following site closure. Interior Alaska can be a challenging place to successfully delineate and monitor groundwater contamination. Our unique experience using extreme-cold-weather sampling techniques and navigating other Arctic challenges such as discontinuous permafrost, frost heave, and frozen wells help ensure project success and keep costs reasonable. We also employ innovative sampling techniques for affordable groundwater assessment at rural and remote sites.

  • Temporary well points
  • Monitoring well installation
  • Well development
  • Sampling
  • Monitored natural attenuation (MNA) studies
  • Plume delineation
  • Hydrogeological characterization and modeling (with partner firm)
  • Well decommissioning and closure

Soil and Groundwater Remediation and Mitigation


Our qualified environmental professionals have experience implementing a wide range of soil and groundwater remediation technologies, designing cost-effective solutions to fit project objectives and overcome site-specific challenges. We specialize in bioremediation of petroleum-contaminated soil and groundwater using low-cost, passive, and sustainable approaches. Our principal chemist Rodney Guritz is involved with the first large-scale field study of phytoremediation in Alaska, using native Alaskan willows and grasses to treat nearly 1,000 cubic yards of diesel-contaminated soil. Arctic Data Services, working with teaming partner Ahtna Engineering Services, recently completed a rural brownfield site cleanup using phytoremediation for treatment of diesel-contaminated soil.

We recognize that complete remediation is not always feasible. We have experience in long-term monitoring and mitigation projects to reduce exposure risk levels to below acceptable criteria, and work closely with regulators to see that a reasonable monitoring program is approved. Our staff designed and installed a sub-slab depressurization system for a commercial building in Fairbanks over soil with extremely high tetrachloroethene (PCE) concentrations. The low-cost system succeeded in reducing indoor air concentrations of PCE by two orders of magnitude within months, meeting stringent health-based target levels. We also have experience with natural attenuation monitoring, institutional controls, soil capping, and other exposure mitigation measures.

We partner with Rescon Alaska for engineering expertise on projects involving remediation-system design and construction. Rescon’s skill set complements our background in chemical fate and transport, making for optimal remedial design and expedient site closure.

Vapor Intrusion Assessment


Vapor intrusion (VI) is the process where volatile organic compounds (VOCs) migrate from soil or groundwater into buildings above a contaminated site or downgradient groundwater plume. VI is a significant potential exposure pathway that must be evaluated for sites contaminated with VOCs. ADS professionals have experience with all aspects of the VI investigation process, including designing and installing mitigation systems.

VI guidance (from the ADEC, EPA, and ITRC) suggest taking a multiple-lines-of-evidence approach to VI investigations. VI is a very complex process, and potentially an expensive one if the right approach is not taken. The science of VI is constantly changing, as are the sampling strategies that support VI investigations. Additionally, every building with VI potential is different, especially in Fairbanks where our building codes are lax and cold-climate conditions present specific challenges.

We take a staged approach, often utilizing passive sampling to reduce sampling costs and improve representativeness and reproducibility of results. We are well aware of the complications of common indoor background sources, and have significant experience identifying such sources and ensuring they don’t interfere with the investigation. With our experience in analytical chemistry, we are prepared to support large-scale VI investigations through field gas chromatography/mass spectrometry (e.g. HAPSITE).

Field Screening


Looking for a “dirt sniffer” to support your next construction project at Eielson Air Force Base, Fort Wainwright, or Joint Base Elmendorf-Richardson? We provide field screening (“dirt sniffing”) services at a competitive rate using experienced staff that will work with your project managers, dirt-work crews, the US Army Corp of Engineers, and the Alaska Department of Environmental Conservation to ensure a successful project with minimal down time.
