Recent Hire
Chris Turner,
MSc, has recently joined The Johnson Company’s growing contaminant hydrogeology group. His Master of Science
degree from the University of Waterloo in hydrogeology is complemented by five years of nationwide consulting experience emphasizing site characterization and remediation planning, particularly for sites impacted by dense chlorinated solvents.
Howe Farm NRD Compensation Project receives Certificate of Completion
The Vermont and Federal Natural Resource Trustees have issued Certificates of Completion for the Howe Farm habitat restoration project. The Johnson Company designed the project, obtained state and federal permits, oversaw its construction, and completed five years of monitoring and reporting on the progress of the restored site towards achieving its full habitat value. This project was the Natural Resource Damage compensation project for the Pine Street Canal Superfund Site in Burlington, Vermont.
Recent MBA Graduate
Glen Kirkpatrick, MSc, MBA, P.G., Senior Managing Scientist with The Johnson Company, recently completed a Master of Business Administration degree from Norwich University, placing in the top five percent of all MBA graduates from over 100 universities in a comprehensive graduate examination. Glen now holds advanced degrees in business and contaminant hydrogeology, which, together with his undergraduate education in environmental engineering and many years of consulting experience, lends to effective multi-disciplinary solutions for his clients.
Comprehensive DNAPL Site Investigation
The Johnson Company recently completed a comprehensive Site investigation at a complex chlorinated solvent DNAPL site in the Northeast U.S. The investigation involved adaptive characterization of complex fate and transport pathways including intermixed plumes from multiple sources, as well as contaminant migration within fractured bedrock. The Johnson Company completed full delineation of contamination in less than 18 months, readying the Site for effective remediation by conductive thermal heating and other complimentary technologies.
Oxygen Injection Success
After a successful pilot study to demonstrate the feasibility of oxygen injection at a petroleum cleanup site in West Lebanon, New Hampshire, a full scale system was installed injecting medical grade O2 into the petroleum-contaminated aquifer. The Johnson Company teamed with Matrix Environmental of Albany, New York, who provided the oxygen generation and manifold equipment. Monitoring has demonstrated successful treatment as dissolved oxygen concentrations have increased 10-fold and total volatile organic compounds in the aquifer have reduced by over 90% in the aquifer.
