POL Operations & Maintenance

Challenge & Solution

Rhea was contracted to operate, maintain, and optimize eight petroleum remediation sites at a federal government facility in North Carolina.  These sites had not been optimized nor moved toward closure. Rhea was tasked to do both.

Project Description & Highlights

Since taking over the systems in June 2009, Rhea has made major changes to most of the systems’ operation.  These changes were made in order to prevent frequent system shutdowns and to remediate the contaminated areas.

Many of these systems were constructed in the mid 90s and had remediated part (or all) of the site.  Rhea suggested pursuing No Further Action on one site that showed no contamination.  Rhea has also shutdown wells and parts of an air sparge system where the groundwater was below the remediation standard for more than four quarters. This approach allowed the system to better concentrate on the contaminant “hot spots.”

Communication with the team members is absolutely crucial during O&M activities.  Rhea submits daily reports to the Client and local supervisors. Monthly O&M reports are written to summarize the month’s data that was collected and to make suggestions for operational changes.  These reports are forwarded to the Client and local supervisors.

Rhea prepares Annual Monitoring Reports (AMRs) for each system to summarize the year’s activities and determine the remediation efficiency and progress of the remediation efforts. These reports are submitted to the federal government and other supervising agencies. The AMRs also discuss possible alternatives to the current remediation efforts and identify if site closure should be pursued.

Through excellent operators and constant system optimization, Rhea has increased system operating efficiencies and moved some sites very close to closure.
