WESA was founded in 1976, specializing in the provision of high-level hydrogeology expertise to meet the clean water and sanitation needs of industry and government.
As public awareness increased and environmental regulation evolved over the past four decades, the company’s service base and areas of expertise broadened significantly. WESA undertook extensive research and development in the areas of contaminated site remediation, water/wastewater treatment, and finding better ways to investigate, characterize and resolve environmental impacts. WESA operated in many industrial sectors, was well diversified, and completed thousands of projects on behalf of hundreds of clients over the years. WESA's service offerings included all aspects of environmental science & engineering, industrial hygiene, occupational health & safety, environmental risk assessment, permitting and management, geomatics and GIS, environmental compliance auditing, and management systems.
In response to client requests, the WESA Group began offering industrial water and wastewater treatment design-build services through WESAtech. The experience demonstrated that there are highly effective synergies between consulting services and solutions implementation.
