Feedback from the clients we’ve supported
I have had the pleasure of working with Groundwater Insight on several challenging environmental remediation projects. In fact, Mark was specifically selected for this work because of his technical background, and his ability to effectively communicate difficult concepts on a very easy to understand level. Mark has been a very valuable team member on these assignments, and has earned himself an excellent reputation with the other members of the technical team. In fact, I believe he has worked with the team members on other projects for other clients. Mark is a good guy who I have enjoyed working with, and as an Environmental Manager, I’d recommend him highly.

ADI has worked with Groundwater Insight on seven different occasions, including not only technical assignments associated with the Coke Ovens/Tar Ponds clean-up, but also in a co-teaching role, as a co-author of a technical paper, as well as in his position as the regional representative of IAH for the Atlantic Region. We enjoyed working with Mark in the team approach to these tasks, finding him to be open to new ideas, technically competent, inquisitive, and at ease in teaching and other public forums. In those tasks where he has taken on the role of project manager he has shown himself to be very effective in utilizing the skills of the various team members to meet the client’s scope, schedule and budget.

I worked with Mark on at least three projects related to development of Risk Assessments for metals and hydrocarbons. Mark was involved in both a primary and review capacity. The project work with Mark was performed in a timely manner within budget and the client was pleased with the resulting reports. Mark conducted a workshop on the Atlantic Risk Based Corrective Action (RBCA) for our staff. We found the workshop to be well organized, well presented and very useful to our staff. Mark’s experience and technical knowledge meant that presentation was very relevant to our activities. I have always found Mark to be very accommodating both as a client for his services and as a partner in our projects.

Groundwater Insight is a key member of the Project Team for the Meadow Avenue Remediation Project near Vancouver, BC. Mark provided important “Insights” into the modelling of monitored natural attenuation of PAHs in groundwater that literally helped shape the design of this award winning, innovative sediment isolation system. His knowledge and stature in the fields of MNA, contaminant transport and DNAPL migration remains essential to the Project Team’s success.

Mark served as a technical expert/advisor in the development of a Monitored Natural Attenuation program for a significant chlorinated hydrocarbon plume from a former coatings facility in New Jersey. With a Ph.D. from Waterloo, we expected Mark to possess specialized knowledge regarding chlorinated solvents. However, Mark led our team in discussions and negotiations with the regulating agency and ultimately obtained approval of the MNA program. Mark’s demonstrated expertise in complex chemical movement and interactions within a complex glacial till and bedrock environment became the central point to regulatory acceptance.

KEY and Groundwater Insight have worked as a team on numerous projects dating to 1997. The work has involved numerical groundwater fate and transport modeling to support the selection of a capping and containment site-wide remedial action and the development and implementation of unique field investigation approach for demonstrating the occurrence of natural attenuation. I have found that Dr. King’s technical capabilities and written and oral presentation skills have been a tremendous asset and have contributed greatly to the success of these projects. Dr. King has always been extremely responsive and I would strongly recommend him to anyone in the market for hydrogeological consulting services.

Groundwater Insight has worked with URS on several projects and has provided excellent service and work products. Groundwater Insight personnel have proved to be excellent teaming partners and have brought essential value-added services to our clients. Groundwater Insight personnel are extremely technically proficient and bring along with them the necessary communication and presentation skills to make very technical work understandable. Groundwater Insight has worked out extremely well as a teaming partner and provides straightforward proposals, accessibility to technical expertise, and accurate billing which is critical to the overall management of projects.

We have worked with Groundwater Insight for over three years on large-scale contaminated site investigations, utilizing numerical modeling tools for analysis and assessment of remedial options. Mark’s technical knowledge of the site conditions and processes, combined with his ability to appropriately represent these in modeling tools provides a crucial link between all project team members. He provides prompt and critical evaluations of model results in the context of field observations, effectively guiding project progress with consideration of tight timelines and technical aspects of the projects.

Mark and I have worked together on several projects for a mutual client. These projects involved investigation and evaluation of natural attenuation of constituents in groundwater at federally regulated wood treating sites. Mark is expert in the field of natural attenuation. Using his expertise and clearly written technical approaches and data evaluation, we were able to convince the regulatory agencies to consider natural attenuation as a potential remedy for the sites. Mark is a pleasure to work with, and easily fit in with our multidisciplinary team for these projects.
