Investigation Services


As a current or perspective facility owner or operator, gaining an understanding of the impacts of current or historic operations on the environmental condition of a parcel of land can be a costly and often confusing endeavor. Even more concerning is having the confidence to decide what it will cost to remediate or mitigate soil, groundwater, surface water, sediment, soil vapor or indoor air. We understand your objective and it is our mission to gather those data that allow you to make an informed business decision. Starting at the Phase I, we will ensure that you understand the risks and risk drivers and the potential impacts each could have on your business decisions. As you proceed through each phase of characterization, you can rest assured that our team of professionals with backgrounds in engineering and the sciences are using the most appropriate and cost-effective characterization tools to get you the information you need in the timeframe you need it in. Real-time, risk-based, fast-paced, dynamic, cost-effective, systematic, streamline – these form the basis of what you can expect from us and we will deliver each and every time. Loureiro’s track record is clear, we under stand your needs and we will not stop until they are met.
