Environmental Remediation Services

BURLESON'S environmental staff has extensive experience performing environmental characterization and remediation projects. Projects have been conducted under both Resource Conservation and Recovery Act (RCRA) and Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). We use a similar approach at each remediation site, although site specific issues are taken into account. Burleson staff have specialized experience in managing acid runoff from abandoned mines.

Burleson staff has designed groundwater remediation, soil remediation, and dual-phase extraction systems. Treatment systems for extracted groundwater have included air stripping; ultraviolet oxidation and granular activated carbon; and deep well injection. Burleson recently installed an ozone sparging system to remediate a petroleum plume. Other in situ systems have included iron walls to remediate chlorinated solvents, air sparging, and dual phase extraction. We have developed monitored natural attenuation plans at many sites.

Before implementing remediation, Burleson first ensures that site characterization has been adequate. Burleson's strategy is to develop two key elements to ensure that data collected during a field investigation will ultimately lead to appropriate site characterization and aid in selecting a remediation technology. The first element is to develop a conceptual site model (CSM), in which chemical releases, exposure pathways,and receptors are identified. The second element is to develop data quality objectives (DQO). Burleson staff use the seven step DQO process recommended by the Environmental Protection Agency (EPA) to ensure that adequate data is collected. By developing a CSM and DQOs before a field investigation, sufficient samples can be collected and appropriate parameters can be analyzed.

Burleson staff used CSM and DQO tools at a naval installation site. The CSM indicated that groundwater was only considered to be a threat to aquatic receptors and notto human health. This information was used to establish appropriate detection limits for analysis of groundwater samples. DQOs were used to ensure that sufficient samples were collected and that collected samples   were also analyzed
  for parameters that
  would influence
  potential treatment
  technologies. By
  using these
  tools,our clients get
  the most "bang for
  their buck" out of an   investigation.

Burleson staff have used a probabilistic risk assessment approach for allowing higher concentrations of polychlorinated biphenyls (PCBs) to remain in soil than would normally be allowed.

We believe it is crucial to involve engineers, geologists, and regulatory specialists during all stages of an environmental investigation and remediation project. Our comprehensive approach and extensive experience remediating environmental contamination make us an ideal firm to solve your environmental problems.
