Thierry CarriouDr. Gilles Wendling has provided assistance with review on technical projects ranging from evaluation of proposed open loop geothermal well impacts on neighbouring public water supplies to advice regarding high capacity water well screen design.

Gilles is a very knowledgeable colleague and excels at providing alternative points of view when dealing with complex hydrogeologic (groundwater) issues. We recommend his services.

Reg WhitenIn my role as Watershed Steward for the City of Dawson Creek over the past few years, a major effort has focused on increasing our understanding of surface and groundwater interactions in its domestic water supply area – the Upper Kiskatinaw River in the Upper Peace River basin of north-east BC. This work has required us to build upon limited, but rapidly expanding knowledge of watershed function from City, government, industry and academic sources. GW Solutions has provided valuable services in furthering this scientific understanding through the creation of hydrogeological cross-sections, reviewing hydrological/land-use research and providing recommendations for improved groundwater monitoring and protection. Another important function has been in attending and delivering technical presentations to various public and stakeholder audiences as we endeavour to build our interest-based approach to water security and stewardship.

The careful attention provided by Dr. Wendling in addressing our Watershed Program capacity-building objectives has been instrumental in helping us shape our current and future collaborations.

I would strongly recommend GW Solutions in supporting the critical need of local governments to understand and strengthen their water supply and quality management capabilities.

Allard OckeloenIn the capacity of Developer, we are typically looking for sustainable water solutions in support of new development.  What impressed me from the moment we started working with GW Solutions is the professionalism that runs throughout the entire team; you would expect a high understanding of all things ‘hydrology’, but with Dr. Gilles Wendling and his team, you get much more:

[+] Local knowledge and historical data that helps profile aquifers, which in turn shortens the time required to locate drilling locations,

[+] Geological resources on staff with Mr. Arnd Burgert, presents another layer of knowledge and information from which decisions can be made more accurately,

[+] Excellent depth in the relationships that Dr. Wendling has fostered over the years at all levels of bureaucracy/government relevant to his field, relationships that allowed us to obtain clarity on process and meet our goals quickly,

[+] Reporting detail in his work is precise and complete and tailored so that the reader can understand the issues fully,

[+] Credibility, Dr. Wendling presents well and has the gravitas and respect in the industry to be accepted as a leader in his field. This is critical when our company presents to local government; our consultants must be seen as the strongest and most respected in their lines of expertise,

[+] Presentability;  Dr. Wendling (and those on his team that I’ve met) are all highly skilled, personable, organized, professionals and those qualities are all very valuable to us.

Often a project will require us to invite our consultants into our higher level meetings/presentations with government and it’s a great comfort to know that when it comes to our Hydrologist, we’re in good hands.

Bob KitchingWestern Maritime Institute required an assessment of the  impact of new student accommodation on the local aquifer to meet Regional District Planning requirements.

I contacted GW solutions who understood fully the requirement of the RDN, quoted us a fee for their services and developed a complete report meeting the  full RDN requirements, on time and on budget.

Faye-Smith_MVIHESMid Vancouver Island Habitat Enhancement Society (MVIHES) has been involved with the Englishman River watershed for more than twelve years. In that time we have endeavoured to increase salmon stocks by improving and protecting habitat and through public education. Of some concern to us was the fact that the river has to supply summer drinking water to several communities in the area and summer flows are often alarmingly low. A few years ago we realized that we were missing a large part of the puzzle because of the lack of information about groundwater in the watershed.

We had discussions with Dr. Wendling about how his company could assist us and very soon we were on track to engage in a project that would greatly increase our knowledge about groundwater in the watershed and how groundwater and surface water interact. This information is very important to us because we now know that groundwater, indeed, is essential to the base flows in this river and we are implementing actions to protect the recharge areas to ensure that there will continue to be sufficient water for fish and the ecosystem.

Because we are a non-profit society, we needed to raise funds and GW Solutions was very helpful in assisting us so that we could make successful applications for funding. Dr. Wendling and the company are highly respected in this mid-Island community so agencies are more than willing to cooperate with us. I recommend GW Solutions for their high quality work and their caring approach.

John Snyder - CoalWatchSince early 2010, Dr. Gilles Wendling of GW Solutions has been a key advisor and technical expert to CoalWatch on hydrology/hydrogeology issues regarding the proposed Raven Coal Mine Project. Aquifer and ground water concerns surfaced early in the environmental review process as key public issues.

Whether being the featured speaker at town hall meetings, providing comments and technical review during the drafting of the Application Information Requirements (AIR), or working with the Environmental Law Centre at UVic on a request to VIHA for a Drinking Water Protection Order, Dr. Wendling’s expertise has been invaluable.

I would also add that all the local governments in the Comox Valley have passed motions requesting comprehensive aquifer mapping in the areas impacted by the proposed Raven Coal Mine, due mainly to the technical review and highlighting of AIR deficiencies done by Dr. Wendling.

CoalWatch has been able to raise public awareness around the aquifer and ground water issues regarding the proposed Raven Coal Mine Project mainly because of the “above and beyond the call of duty” work by Dr. Wendling. I would highly recommend Dr. Wendling to anyone seeking expertise on hydrology/hydrogeology issues.
