A property’s condition is important to the health and safety of everyone and everything around it. Leaks, spills, buried wastes, soil, and water impacts not only have adverse effects on the environment but also to your company and your respective business decisions. Protecting your assets is serious business, and RETTEW’s GeoEnvironmental team has the expertise and insight to help prevent and mitigate contamination incidents. We can use our skills for property you already own or property you and your company may want to purchase.

Environmental due diligence—the process of assessing a property for contamination risk—is a critical step in any development project, especially in the energy and industrial markets. Our team of environmental experts can investigate and evaluate your site and uncover potential environmental liabilities before you buy, build, or expand.

Our GeoEnvironmental team can also help you better identify and manage hazardous materials and prepare for the unexpected, such as formulating a spill contingency plan or hazardous materials sampling and abatement plan. In the event our due diligence identifies a problem, RETTEW excels in subsurface investigation, characterization, and remediation strategies through appropriate state and federal regulations.

Our GeoEnvironmental services team is closely aligned with other engineering and technical specialties. Partnering with a firm as diverse as RETTEW gives you access to unparalleled environmental expertise, ensuring you’re safe and compliant.
