Environmental Engineering

GRA has successfully resolved various problems associated with environmental engineering. These include the areas of wastewater collection and treatment, storm water collection and discharge, water distribution systems, and site assessments and remediation with respect to the presence of hazardous materials. Within each of these areas we provide services for all stages of a project, from conceptual planning to preliminary and final design of facilities, regulatory compliance, contract administration and construction inspection.

Our professional staff has gained extensive experience in these areas, and, through that experience, we have developed a sound understanding of the issues that must be addressed.
