Environmental Restoration

There are many approaches to site remediation — but which is the best one for your site? Battelle can help you cut through the complexity and understand your risks and options so you can make the best remediation decision. 

Applications

Battelle provides comprehensive environmental services for site assessment, characterization, management, monitoring and closure. We can help you address sites contaminated with a broad range of contaminants, including hydrocarbons, Persistent Organic Pollutants (POPs), per- and polyfluoroalkyl substances (PFAS) and other emerging contaminants. PFAS are fluorinated organic chemicals and include PFOA, commonly referred to as C8 or ammonium perfluorooctanoate, and PFOS also known as perfluorooctane sulfonate.

Capabilities

Battelle is leading the way in the development of new approaches for characterization and remediation of sites contaminated with a broad range of problematic contaminants. We do more than standard studies and remediation activities. Our team brings unmatched scientific and technical expertise in remediation options, as well as a deep understanding of regulatory requirements and stakeholder concerns, to find new and innovative options.

We can help you at every stage of the remediation process, from initial site assessment to site closure. Our team will: 
  • Design a characterization strategy to find the answers you need for effective decision making 
  • Identify and quantify human health and exposure risks and develop a framework for determining unacceptable risks
  • Optimize your remediation plan to address regulatory concerns and meet the needs of all stakeholders 
  • Develop new technologies and methods to address emerging contaminants and difficult remediation challenges

Services

Site Characterization 
Battelle combines field experience and world-class laboratory analytical services to give you the answers you need to understand complex contamination problems. We bring together all the expertise you need—including fate and transport modeling, chemistry, environmental science, toxicology and data analytics—to provide accurate, defensible data and objective analysis.

We offer: 
  • Accurate identification and quantification of a broad range of contaminants (including persistent volatile organic compounds  (VOCs), per- and poly-fluorinated alkyl substances (PFASs), heavy metals and hydrocarbons) in soil, sediment, water, air and biological tissue 
  • State-of-the-art sampling and analytical methods for low-level detection, high-resolution site characterization, source zone characterization and analysis of comingled contaminant plumes
  • Modeling and 3D visualization tools to help you understand the nature, extent, fate and transport of contaminants on your site and analyze exposure scenarios
  • Accurate, objective evaluation of human health and ecological risks
  • Method development and validation for non-standard sampling and analytical challenges

Remedy Selection and Optimization 
Selecting the right remedy for contaminated sites requires a clear understanding of the end goals, costs and treatment options. Battelle can help you optimize your remediation plan to control costs, improve treatment effectiveness, and move your site towards closure as safely and efficiently as possible. We offer objective, science-based answers tailored to the unique characteristics of your site.

Our team provides: 
  • Feasibility studies to evaluate the cost and effectiveness of different remediation options based on site characteristics, contaminant levels, and cleanup goals 
  • Remedy selection, design and optimization
  • Assistance with developing remedial exit strategies, transitioning to lower-cost, less aggressive methods (treatment train approach) and achieving final site closure
  • Designing and implementing optimized long-term monitoring strategies
  • Technology development and transfer to address non-standard remediation challenges

Benefits

At Battelle, we are working to make contaminated site remediation more effective, affordable and sustainable. Our deep understanding of the science allows us to develop site characterization and management strategies tailored to your site characteristics, goals and priorities. We can work with you to find the most time- and cost-efficient approach to remediating your site and help you move towards site closure with confidence. 

Encapsulating Fungal Enzymes for Safer Oil Remediation

Challenge

Mycoremediation is a form of bioremediation that uses fungi to break down and extract contaminants from the environment. Ligninocellulosic enzymes (including lignin peroxidase (LiP), manganese peroxidase (MnP) and laccase) produced by wood-rotting fungi can also break down complex carbon-based chains found in heavy crude oils and other persistent environmental pollutants such as dichlorodiphenyltrichloroethane (DDT), polychlorinated biphenyls (PCBs) and dioxins. This makes mycoremediation a promising treatment alternative for soils and sediments contaminated with crude oil wastes, textile effluents, organochloride agrochemicals, pulp effluents and other pollutants. 

However, using live fungal cultures is problematic. Fungal organisms must have specific substrates and environmental conditions in order to produce the necessary enzymes. Introducing live non-native species may also present its own environmental risks. Applying the enzymes rather than the live cultures is considered to be safer and enables more precise application and dosage. Because the protein molecules in the enzymes degrade quickly when exposed to unfavorable environmental conditions, a solution was needed to stabilize the enzymes for storage and transport and activate them once they are applied. 

Solution 

Battelle developed an encapsulation technology to protect the enzymes from physical and chemical degradation. Fungal enzymes are extracted from the fungi in the lab and encapsulated in a special polymer. The biodegradable shell is engineered to swell and break open in the presence of water and/or by the action of microbes on the polymer. This allows the enzyme to be kept in a stable formulation. The shells also provide necessary ions and activators for the enzyme to stay in the active state and reduce the potential for denaturation. This ensures that the enzymes will be delivered exactly when and where they are needed, without the risk of introducing a potentially invasive fungal species into the environment. The shell design may be altered to target different contaminants of interest. 

Results

Studies conducted at Battelle have demonstrated that the encapsulated fungal enzymes are highly effective for biodegradation of heavy weathered crude oil with alkane chains representing fractions higher than C35. The enzymes break down the heavy hydrocarbon chains into shorter chains that can be more easily biodegraded by naturally occurring microbes. The technology has since been patented and is now available for remediation efforts at sites contaminated by petroleum hydrocarbons. Battelle is currently conducting tests to demonstrate its efficacy for sites contaminated by agrochemicals, PCBs and munitions constituents.
