Assessment, Investigation & Characterization

ROKEN has extensive experience assessing environmental liabilities for our clients involved with property transfers, site development, and mergers and acquisitions. We are skilled in investigations that define the nature and extent of the contamination in soil, water, air and materials. We use the most appropriate methods to cost-effectively achieve our client’s goals. Our capabilities include the use of analytical and numerical computer modeling applications to characterize the current and potential impacts to sensitive receptors, which allows for the development of risk-based corrective action options. We communicate our findings in a clear and concise manner and utilize graphical illustrations to present our findings and promote effective decision-making.
