P. E. Haas & Associates, LLC provides expert, technical, independent quality assurance oversight, and hands-on services which include: collecting, analyzing, and evaluating ground water natural attenuation geochemical parameters; passive diffusion sampler data; soil gas data; soil, soil gas, and ground water vertical profiling data; and performance monitoring data for numerous remediation technologies. Available technical staff (e.g. Patrick E. Haas, Todd H. Wiedemeier) are experienced in the development of sophisticated technical protocols like the US EPA Technical Protocol for Evaluating Natural Attenuation of Chlorinated Solvents in Ground Water. We specialize in the use of expedited site characterization techniques (e.g. US EPA TRIAD, ASTM D6235-04) through the use of global positioning systems, direct push tools/sensors, field test kits, on-site volatile organic or metals analyzers, etc. in order to substantially reduce the time and costs to characterize a site. Technical staff have the expertise to develop conceptual site models and the practical know-how to identify technology-specific data to guide the proper selection and design of more effective remediation systems. Engineering and project execution services include start to site closure involvement in the project management, design, drafting, installation, and operation, and maintenance of bioventing systems, soil vapor extraction systems, excavation, conventional and vacuum-enhanced LNAPL free product recovery systems, dual phase extraction systems, air and gas sparging systems, biotic and abiotic permeable reactive treatment walls, enhanced bioremediation via organic carbon substrate addition projects, phytoremediation applications, remedial process optimization efforts, and numerous risk-based approach and natural attenuation. P. E. Haas & Associates, LLC is results-driven and has the capability to develop risk-based cleanup solutions that are technically defensible and compliant with local, state, and federal regulatory programs.

Experience:

Patrick E. Haas has hands-on experience collecting, analyzing, and evaluating ground water natural attenuation geochemical parameters, passive diffusion sampler data, soil gas data, vertical profiling data, and performance monitoring data for numerous remediation technologies. His experience includes start to site closure involvement in the project management, design, installation, and operation, and maintenance of bioventing systems, soil vapor extraction systems, conventional and vacuum-enhanced LNAPL free product recovery systems, dual phase extraction systems, air and gas sparging systems, biotic and abiotic permeable reactive treatment walls, enhanced bioremediation via organic carbon substrate addition projects, phytoremediation applications, remedial process optimization efforts, and numerous risk-based approach and natural attenuation. He served on the National Research Council Remediation at Navy Facilities Committee, ASTM Remediation by Natural Attenuation Task Group and is a co-author of the US EPA Technical Protocol for Evaluating the Natural Attenuation of Chlorinated Solvents Dissolved in Groundwater and the AFCEE Test Plan and Technical Protocol for LNAPL Free Product Recovery. Mr. Haas has served and continues to serve as an instructor for environmental remediation courses for the National Ground Water Association, Alaska Department of Environmental Conservation, and the United States Air Force. Mr. Haas received a Masters of Science Degree in Environmental Sciences from the University of Texas at San Antonio , and a Bachelor of Sciences degree in Chemistry, and Biology with Honors from Southwestern University .
