Krzysztof S. Jesionek, P.E.

Krzysztof Jesionek is a Principal Environmental Engineer based in California with more than 35 years of experience focused on solid and hazardous waste management, including facility design and closure, permitting, construction management, and construction quality assurance (CQA) in the United States, Canada, and Poland.

As a consultant, Krzysztof has managed both site assessments and remediation projects for contaminated groundwater and soil. He has prepared permit and design documents for numerous landfill expansions, prepared site development and operations plans, storm and surface water management plans, managed construction quality assurance services, and has overseen all engineering and construction aspects for landfill containment and closure assignments. He has also designed and permitted municipal solid waste landfill expansions throughout California, Oregon, and Washington, and he regularly works on landfill closure and conversion projects.

To advance the state of the practice, Krzysztof is one of the country's leading experts in engineering applications of scrap tire shreds. He has contributed to regulatory guidance regarding the use of scrap tires in monofills, and authored five "How To" manuals for the State of California for the use of tire shreds as alternative daily cover; final cover foundation layer; leachate drainage media; landfill gas collection media; and operations layer material. He conducted and published research on tire shred performance criteria, material characteristics, and applications issues such as equipment, labor, and storage requirements; tire shred specifications (e.g., size, thickness, metal wires); placement; monitoring methods; restrictions; and health and safety concerns.
