  • Humble Beginnings


    Leonard Mold and Die was founded in Denver in 1956, a small business originally specializing in toolmaking and machining. Thanks to its history of innovation and commitment to quality, Geotech quickly became a respected name in manufacturing. Today, Geotech is a leading manufacturer of environmental equipment for a variety of industries. However, the company has never forgotten its roots.

  • 1978

    Partnering with USGS

    Geotech founder, Jerry Popiel, developed the Geopump Peristaltic Pump with the U.S. Geological Survey for the purpose of collecting shallow groundwater and surface water samples to comply with EPA Clean Water Act of 1972 initiatives. As a result of the partnership, Geotech's equipment became industry standard. Geotech's pumps are now used by environmental professionals around the world to collect water samples for analysis.

  • First of it's Kind


    In response to new EPA regulations, Geotech announced the launch of its new bladder pump system. This system was the first of its kind in the industry, and it represented a major development for wastewater management. The EPA introduced low flow purging and sampling methodology, and with its intuitive design and user-friendly interface, the bladder pump system was easy to operate and maintain. Wastewater management is now easier and more efficient than ever before.

  • 1997


    Geotech's acquisition of ORS, Inc. in 1997 was a watershed moment for the company. Not only did it broaden Geotech's influence into active product recovery and interface meters, but it also allowed Geotech to tap into a new market in New Hampshire and continue its growth trajectory. The move came at a time when hydrocarbon contamination concerns were leading regulatory clean-up efforts, and the ORS product line gave Geotech the ability to provide much needed equipment for clients.

  • Keck Instruments


    In 1999, Geotech announced the acquisition of Keck Instruments. The new pneumatic hydrocarbon recovery systems and interface meters were designed to provide superior performance and reliability. The acquisition resulted in the launch of the Lancing, Michigan office location and further advancements in remediation technology.

  • 2005


    Geotech acquires Marschalk Corporation, representing a major milestone for the company and its water quality equipment production. This acquisition enhanced Geotech's bladder pump technology offerings and helped to launch its Raleigh, NC office location. The location provides Geotech with a new base of operations in the Southeast region of the United States. With new access to a large potential customer base, the company can now better serve its existing customers in the region.

  • Headquarters gets an Upgrade


    Denver has been the home of Geotech since the company was founded in 1978. The city has seen the company grow from a small machine shop to a leading manufacturer of environmental equipment. In 2006, Geotech moved to its current 125,000 square-foot manufacturing plant and headquarters in Denver.

  • 2011

    International Expansion

    Geotech broke ground on its first international office location in Beijing, China in 2011. The new location improved Geotech's international relations and export channels to global customers and distributors. This same year Geotech acquired Bisco which strengthened Geotech's position in the market and allowed the company to set up shop in southern California. Geotech's expansion into Beijing and California was a key moment in the company's history, providing Geotech with a strong foothold in the global market.

  • Improving Worker Safety


    Worker safety has always been a priority within Geotech. In cooperation with Arcadis, the company manufactured the ZipLiner, a cutting-edge device designed to improve worker safety conditions when opening traditional liners. By making worker safety a priority, Geotech helps to create a safer, more efficient field sampling process for our clients. The ZipLiner is just one example of how Geotech constantly innovates to improve worker safety. Geotech continues exploring new technologies and ideas to make sure that our workers can do their jobs safely and efficiently.

  • 2013


    Geotech acquired a portion of INW (Instrumentation Northwest), which enhances electric submersible pump configurations and resulted in the launch of the Kirkland WA and Sacramento CA office locations. The acquisition of INW allows Geotech to expand its product offerings and continue to provide the highest level of customer service.

  • Meeting New Standards


    Geotech began certifying ISO 9001:2008 back in 2013, affirming our commitment to quality management principles that assure a customer-focused approach to design, development, production, and sales and service. This was an important milestone for Geotech, and we continue to update this certification to this day.

  • 2015

    Aqua VISION

    Geotech announced the acquisition of Aqua VISION. This move resulted in the commercialization of the Colloidal Borescope, a groundbreaking tool for characterizing groundwater flow direction and rate in situ. Geotech is now positioned to provide our customers with the most advanced tools for groundwater flow.

  • To the Skies


    Geotech introduces unmanned aircraft or drones with the acquisition of Leptron Industrial Robotic Helicopters, Inc - an innovative technology being introduced to environmental remote sensing and aerial surveying. The addition of Leptron's innovative technology provides Geotech customers with a new tool for environmental research and assessment. The use of drones has already revolutionized many industries, and it is clear that the potential applications for this technology are virtually limitless. Geotech is committed to providing its customers with the most advanced solutions available, and the acquisition of Leptron is yet another example of this commitment.

  • 2017


    Geotechnical Services join the Geotech regional service center team in Orange CA in a partnership to better serve Geotech and Geotechnical Services customers nationwide. Today, the regional service center team provides an invaluable resource for Geotech customers across the country.

  • Extrusion


    Geotech acquires Hi-Tee plastics of Denver to expand plastic extrusion manufacturing capacity while continuing to make OEM parts. The acquisition helped Geotech to expand its plastic extrusion manufacturing capacity and continue to provide high-quality products to its customers.

  • 2019

    Improving Weather Forecasting

    In 2019 we announced our contract manufacturing agreement with Anemoment to produce and distribute the world's smallest and lightest 3D ultrasonic wind and weather sensor. The sensor goes on to be used in a variety of applications, including consumer electronics, automated weather stations, and drones.

  • Water Sampling Revolution


    Innovation is key to protecting our environment and combating the continuous increase in toxins. That's why we chose to partner with Thyng Environmental Industries, LLC to manufacture and distribute their patented FieldSink Environmental Station. Providing a cleaner and quicker solution to water sampling in the field not only improves the experience for the environmentalist, but also provides less contaminated samples which improves the industry as a whole.

  • 2023

    Digging Deeper

    Geotech's acquisition of Delta Epsilon Instruments stands as a significant advancement in the field of geotechnical technology. This strategic move not only broadens Geotech's portfolio with Delta Epsilon's well-regarded well logging systems for groundwater exploration but also sets the stage for potential innovations in downhole compatibility.
