High-Density Conceptual Modeling: Because a Guess Isn’t Good Enough
RPI® is the ideal solution for consulting teams seeking an in situ remediation company partner that brings evidence‑based design, field discipline, and lab feedback to complex sites. Our approach is simple — from site understanding to in‑ground performance, the right outcome starts with the right picture.
Our high‑density, quantitative conceptual site modeling (qHRSC) and Remedial Design Characterization (RDC) turn a remediation site assessment into a precise in situ design, so that we place treatment at the points, depths, and loadings to intersect the contamination. This data‑led approach sets the stage for reliable field performance.
Successfully Closing Sites for Over 20 Years
We’ve unquestionably proven that a remediation-specific investigation paired with one of our treatment products, BOS 100® or BOS 200®, and a quality installation almost always achieves project cleanup goals. 95% of first-time Trap & Treat® product users use the products again and again on additional projects. Our methods and solutions are supported by quantifiable data. We’ve formed a group of companies in the industry trained in the RPI® approach. Our approach works—because we go the extra mile.
