About GEMS

Your Partner in Practical Environmental Compliance.

Grounded in Practical Environmental Expertise

Groundwater Environmental Management Services (GEMS) was founded in 2005 to meet the growing demand for a practical, real-world approach to the increasingly complex environmental regulatory and compliance challenges faced by the construction and land development industry. Since then, regulations have only become more stringent, environmental obligations more demanding, and owner requirements more detailed, making environmental compliance a critical factor that can impact project budgets, timelines, and success.

Rather than taking a one-size-fits-all approach, GEMS was built to provide solutions that work on the ground, in real-time, with a clear understanding of how construction and development projects actually operate. Our approach is hands-on, responsive, and deeply rooted in the realities of the job site.

Filling the Gap Between Regulators and Developers

GEMS has grown by combining boots-on-the-ground experience with exceptional service and a commitment to bridging the gap between regulators and our clients. We manage everything from routine, day-to-day inspections to urgent environmental emergencies. Our focus on construction and land development means we don’t just understand the rules—we understand how to apply them efficiently and effectively in real-world situations.

Whether we’re collecting baseline data, classifying wetlands, preparing environmental impact statements, relocating fish and wildlife, or providing construction site monitoring, we bring the same practical mindset to every project. Our innovative, win-win solutions satisfy regulatory policy while remaining feasible in the field. That’s why GEMS is trusted by environmental ministries, conservation authorities, and municipalities alike.
