DPRA performs site investigation and remediation on a wide spectrum of properties encompassing complex and highly-contaminated industrial sites to commercial, retail, and residential properties in urban and rural settings. Contaminants routinely encountered in the soil and groundwater include solvents, petroleum and other hydrocarbons, metals, PCBs, and perchlorate. On many projects, DPRA works closely with regulatory agencies to obtain workplan approvals, site closures, and other liability assurance letters as required by the parties involved in a property transaction. In most cases involving property development, timing is of utmost importance and quick turnaround is critical. We know the process, people, and technical requirements and we can effectively meet the project needs and schedules.
