Washington River Protection Solutions Awards Freestone Subcontract to Support Tank Farm Soil Investigations

October 3, 2013

Richland, WA - Washington River Protection Solutions, LLC (WRPS), has awarded Freestone Environmental Services, Inc. a subcontract to develop regulatory documents and interpret characterization data in support of Hanford Tank Farm soil investigations. WRPS is the Department of Energy Office of River Protection prime contractor at the Hanford Site and is responsible for safely managing radioactive tank waste and reducing the risk to the environment until it is prepared for disposal. The waste is stored in 149 older single-shell tanks and 28 newer and safer double-shell tanks that are grouped into 18 farms near the center of the 586-square-mile Hanford Site in south-central Washington. There are 56 million gallons of highly radioactive and chemical tank waste material left over from years of World War II and post-war production of nuclear weapons. Historic losses of waste from the tank systems have led to soil contamination in and around the Tank Farms.

As part of interim and final remediation actions for the tank farms, soil contamination associated with the tank farms must be evaluated. Freestone will evaluate historical data and develop detailed plans for obtaining new soil characterization data. The new data will be analyzed and interpreted to develop visualizations and site conceptual models. The conceptual model information will address contaminant sources, environmental setting including historical release information and hydrogeologic data, spatial variability, flow pathways relative to shallow and deep vadose zone contaminant distributions, and associated groundwater contamination. In addition to developing technical and regulatory documents, Freestone will provide WRPS technical support at meetings with DOE, regulators and stakeholders through all phases of the work. With option years the contract may extend through Fiscal Year 2017.

Small Business Innovation Research Grant Awarded for Hexavalent Chromium Sensor Development

June 21, 2013

Richland, WA The U.S. Department of Energy Office of Science awarded Freestone Environmental Services, Inc. a Phase II Small Business Innovation Research (SBIR) Grant to develop a sensor capable of measuring hexavalent chromium while submerged in a groundwater monitoring well. Hexavalent chromium is a carcinogen and industrial contaminant found in groundwater. The $1Million research grant follows the successful demonstration of a Phase I SBIR proof-of-principle feasibility study that Freestone conducted in 2012. The Phase II grant will be applied over a two-year period and is intended to advance the development of new, promising technologies in areas deemed critical to the Department of Energy's mission. The ability to provide real-time, direct measurement of hexavalent chromium in groundwater, and send that data out via radio signals from a remote monitoring location has world-wide application.

Hexavalent chromium is used for the production of stainless steel, textile dyes, wood preservation, leather tanning, and as anti-corrosion and conversion coatings. The popular movie, "Erin Brockovich" led to the wide spread notoriety of the extensive hexavalent chromium contamination found in groundwater beneath Hinckley, California and health effects attributed to exposure to industrial workers and residents.

At the U.S. Department of Energy's Hanford Site, enormous quantities of sodium dichromate (which dissolves in water to hexavalent chromium) were shipped in by rail tanker cars for use as an anticorrosion agent in reactor cooling water systems. Spills and leaks of dichromate solutions and direct discharge of cooling water to the ground adjacent to the Columbia River resulted in over 5 square miles contaminated at levels above 10 parts per billion. Sodium dichromate was also used in the plutonium separation process performed in the central plateau of the Hanford Site and is found in groundwater contaminant plumes there as well.

Hexavalent chromium readily moves with groundwater. Its concentration in groundwater contaminant plumes is affected by proximity to the spill source, interactions with surface water, or when drawn toward a pumped well. The ability to measure hexavalent chromium plumes is important in determining whether drinking water supplies or sensitive species such as young salmon may be exposed to harmful amounts of the contaminant. Measuring plume movement and distribution is also important for determining the approach taken to remediating a contaminated site, and in evaluating the effectiveness of a cleanup.

Inspiration for this sensor springs from Freestone's experience investigating chromium contaminated soil, groundwater, and river bed sediments at the Department of Energy's Hanford Site over a number of years. Conventional methods for measuring hexavalent chromium concentration require collecting a sample and then performing multiple steps to prepare the sample for analysis either in the field or for shipping to an off-site laboratory. That conventional process is time consuming, cumbersome, and subject to human error. The costliness of conventional methods limits the quantity of measurements that can be practically obtained.

Freestone's Senior Geochemist, Steve Hall is the inventor of this novel technology which uses near-ultraviolet absorbance spectrophotometry and compensates for turbidity interference. The sensor does not require addition of chemical reagents or sample filtering like conventional methods. It is also sensitive across a broad range from a few parts per billion to very high concentrations, while conventional methods must first be carefully diluted before measuring high concentrations.The sensor will be equipped so data can be transmitted from remote locations to a data management platform for visualization, analysis, and real-time input to treatment system operations.

A team of Freestone scientists and locally based engineers and fabricators are working together to develop and test sensor prototypes. Freestone plans to begin field testing sensor prototypes this summer. After engineering refinements are made, the firm hopes to demonstrate the sensor at various chromium cleanup sites. In addition to its configuration as a submersible sensor, a portable field test kit has been developed, and a flow-through cell for direct in-line measurement will be built for use in water treatment and industrial wastewater treatment systems.

NOAA Selects Freestone for Scientific, Technical and Programmatic Consulting Support Services Contract

April 23, 2013

Richland WA- The U.S. National Oceanic and Atmospheric Administration awarded Freestone Environmental Services, Inc. a five-year contract to provide Scientific, Technical and Programmatic Consulting Support Services to the National Ocean Service's Office of Response and Restoration (OR&R). OR&R is a center of expertise in preparing for, evaluating, and responding to threats to coastal environments, including oil and chemical spills, releases from hazardous waste sites, and marine debris. Freestone will serve as a prime contractor to OR&R with I.M. Systems Group, Inc. as their team subcontractor. Under this contract Freestone will support the OR&R divisions for Emergency Response, Assessment and Restoration, and Marine Debris; and perform related research and development, and business systems support.

OR&R's Emergency Response Division supports emergency response and restoration activities in coastal areas for oil and hazardous chemical spills, provides preparedness aids for response communities, and offers training on the scientific aspects of oil and chemical spill response. They provide scientific support and 24-hour, seven-day-a-week response to spill events.

The Assessment and Restoration Division is responsible for evaluating and restoring coastal habitats damaged by hazardous waste releases, oil spills, and vessel groundings. The division manages this with other federal partners in the Damage Assessment, Remediation and Restoration Program.

The Marine Debris Division undertakes national and international efforts focused on researching, reducing, and preventing debris in the marine environment. It serves to centralize and coordinate supporting activities within NOAA and other federal agencies, as well as using partnerships to support projects carried out by state and local agencies, tribes, non-governmental organizations, academia, and industry.

OR&R has geographically and technically diverse responsibilities such as preparing for potential oil spills in the arctic, and responding to events like Hurricane Sandy, the Deepwater Horizon/BP, and the arrival of Japanese Tsunami debris on the West Coast. The Freestone/IMSG team will employ over 28 scientists, engineers, economists, communication specialists and business administrators primarily in Silver Spring MD and Seattle WA. Staff will also be based at other NOAA locations including Charleston SC, St. Petersburg FL, Baton Rouge LA, Ann Arbor MI, Oak Harbor OH, Honolulu HI, and Anchorage AK.

Phase I Small Business Innovation Research Grant Award for Hexavalent Chromium Sensor

April 12, 2013

Richland, WA. - The U.S. Department of Energy Office of Science awarded Freestone Environmental Services, Inc. a Phase I - Small Business Innovation Research (SBIR) Grant to demonstrate the technical feasibility of a sensor capable of making direct measurement of hexavalent chromium in groundwater and streams. Hexavalent chromium is a human carcinogen and harmful to young salmon at very low concentrations. Phase I explores the feasibility of innovative concepts with awards up to $150,000 over 9 months.

A number of Department of Energy sites have groundwater with large plumes of hexavalent chromium contamination. At the Hanford Site north of Richland, WA over 5 square miles of the aquifer adjacent to the Columbia River are contaminated at levels above 10 μg/L which is a cleanup criterion for protecting salmon. Of the Hanford Site plumes, nearly one square mile is contaminated at concentrations above the drinking water standard of 100 μg/L. Currently available hexavalent chromium analysis methods are time consuming, labor-intensive, and not conducive to obtaining more frequent measurements when rapidly changing environmental conditions must be evaluated.

Freestone has supported their geochemist and Principal Investigator, Steve Hall in creation of a bench top proof-of-principle device for testing and patenting. The infusion of Phase I funding will be used to advance the preliminary proof-of-principle results, and show that the technology can be configured for submersion in monitoring wells. It is envisioned that this new sensor technology will allow automated, real-time measurements to be made from remote locations, and is expected to reduce the considerable costs for monitoring and remediation of hexavalent chromium contaminated sites.

Under the SBIR program, the Department of Energy supports scientific excellence and technological innovation through the investment of Federal research funds in critical American priorities to build a strong national economy. The Department of Energy's SBIR program identifies specific technology development needs and invites proposals from small businesses to address those needs. The competition for a Phase I SBIR Grant is rigorous with a proposal to award ratio of 10-to-1. Small businesses that win awards in these programs keep the rights to any technology developed and are encouraged to commercialize the technology.

Web-Based Platform for Automated Real Time Environmental Monitoring Demonstrated

June 24, 2011

Dan Tyler and Steve Airhart of Freestone Environmental Services, Inc., collaborated with Groundswell Technologies, Inc. in authoring an article published in the Summer 2011 issue of Remediation Journal. The article describes an innovative, web-based, data management platform named Waiora, and its applicability to environmental remediation projects. Freestone has worked with Groundswell (http://www.groundswelltech.com), the developer of the Waiora platform to add new features and demonstrate its performance in acquiring and processing real-time and historical data at a large groundwater remediation project.

Environmental monitoring, data processing, and reporting methods are expensive, labor and resource-intensive, time-consuming, and often inaccurate. The Waiora platform integrates environmental monitoring sensors, telemetry, complex databases, geographical information systems, models, and geostatistical algorithms to provide easy point and click access to real-time data and apply powerful data analysis and visualization tools. Waiora automatically generates contour maps and time-stamped renderings of sensor attributes and multivariate analyses. Algorithms converting sensor-derived head and solute concentration values allow for automated monitoring of mass flux and discharge to evaluate groundwater remediation system performance and contaminant discharges from aquifers to surface-water receptors. The platform provides an opportunity to reduce remediation project life-cycle costs and carbon footprints by minimizing the energy and labor expenditures associated with transportation, data collection, laboratory efforts, report generation, and information dissemination.
