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. 

Characterizing and Monitoring Contaminants at a Complex Fractured Rock Site

Challenge

Battelle has been working with the U.S. Navy for more than 15 years to characterize, treat and monitor groundwater at the former Naval Air Warfare Center (NAWC) Warminster. Groundwater in fractured rock beneath the site is contaminated with chlorinated volatile organic compounds (CVOCs) from historic activities at the site. Testing determined that groundwater concentrations were above maximum contaminant levels set by the EPA. Because groundwater from the site is a source of drinking water for surrounding communities, finding solutions is a high priority for the Navy. The Navy needed to fully characterize the CVOC plume and optimize the treatment and long-term monitoring (LTM) strategies associated with plume remediation.  

Solution

Battelle implemented a passive groundwater sampling approach and optimized the monitoring well sampling network to significantly reduce LTM costs. High-resolution site characterization was used to provide better insights into vertical CVOC distribution and groundwater flow conditions in the fractured bedrock source area. Characterization activities included vertical chemical concentration profiling, collection and field screening of source area rock core samples. Researchers also used borehole geophysics along with vertical borehole flow measurements and identification of water-bearing zones using a heat-pulse flowmeter. Data from field samples was used in combination with bench-scale testing to inform development of an in-situ chemical oxidation (ISCO) implementation strategy for remediation of the plume. 

Outcome

Implementation of the passive sampling and LTM optimization for the COV plume resulted in annual savings of more that $100k for the Navy’s LTM program at the site.
