OPTIMIZATION OF GROUNDWATER TREATMENT SYSTEM LEADS TO ACCELERATED CLEANUP

The fall meeting of the EAB was held September 13, 2007, at Centerville City Hall, Centerville, Georgia. Two topics were briefed: “Remedial Process Optimiza-tion of the Groundwater Treatment System” and “Basewide Industrial and Sanitary Sewer Rehabilitation Plan.” This Fact Sheet provides a summary of the information and topics discussed in the meeting.

The next meeting will be held on January 10, 2008.

The Robins AFB EAB

Recognizing the importance of public involvement in environmental matters, Robins Air Force Base (Robins AFB) has established the Environmental Advisory Board (EAB). The mission of the EAB is to encourage participation of surrounding communi-ties in the Base’s environmental programs and allow community members and other stakeholders to have meaningful dialog with Base officials. Specifically, the EAB serves to promote community awareness and obtain constructive community review, comment, and input on current and proposed actions associated with environmental programs at Robins AFB. The EAB supports the Air Force environmental mission of sustaining readiness, being a good neighbor, protecting human health and the environment for the Base and community, and making smart business decisions. Inside this issue…

Remedial Process Optimization (RPO) is a systematic approach for evaluating remediation systems with the goal of improving their effectiveness and reducing over-all site cleanup time and costs without increasing risks. Efficient use of RPO reduces the Operations and Mainte-nance (O&M) burden across the Air Force, which in turn, makes more funds available to the warfighter.

Mr. David Sanders of Earth Tech, Inc. briefed the RPO efforts undertaken by the Groundwater Treat-ment Plant (GWTP) team members and the Base to continually optimize the operation of the plant and the various remediation systems at the Base’s six Ground-water Treatment System (GWTS) sites. The GWTS is operated under a Performance Based Contract that em-braces a results-oriented philosophy to environmental restoration. Twice each month, operations meetings are held between the Base’s Program Manager, Mr. Phil Manning, and the GWTS operators to systemati-cally review operations at the plant and remediation

JAMES HARDEN RECOGNIZED FOR SIX YEARS OF SERVICE AS EAB COMMUNITY CO-CHAIR

At the September 2007 EAB meeting, Ms. Becky McCoy, Installation Co-Chair, presented a Certificate of Recognition to Mr. James Harden for his dedica-tion to the EAB as Community Co-Chair for the past six years. The certificate was signed by Colonel Ed-ward Piekarczyk, Commander of the 78th Civil Engi-neer Group, and Ms. McCoy and presented on behalf of them, the EAB members, and the Base. Dr. Smyth, the new Community Co-Chair, also recognized Mr. Harden and Ms. Charline Logue for their efforts to make the Robins AFB EAB an award winning pro-gram.

INFLOW & INFILTRATION STUDY PROMOTES SUSTAINMENT OF BASEWIDE SEWER SYSTEM

Robins AFB has over 60 miles of industrial and sani-tary sewer pipeline, a portion of which was first in-stalled at the Base’s inception in the early 1940s. The Base has taken a proactive approach to upgrading this aging infrastructure through careful planning to ad-here to the environmental stewardship objectives of the Air Force. As part of these efforts, a study was recently com-pleted to assess the condition of the Base’s industrial and sanitary sewer collection systems. Mr. Russ Ad-ams, Water Quality Program Manager, briefed the results of the study and highlighted the features of the Basewide Industrial and Sanitary Sewer Rehabilita-tion Plan. A major goal of the study was to identify the extent of inflow of surface water and infiltration of groundwa-ter that enters the sewer system. Inflow and Infiltra-tion (I&I) increases the amount of flow in the system, which may result in the need for capital expenditures to increase the capacity of the piping network and

treatment facilities, as well as an increase in annual O&M costs. Field surveys were performed to identify specific ar-eas on the Base where I&I occurs. Manholes and pump stations were inspected, the flow in the system

I&I STUDY (CONTINUED)

pipes was monitored, smoke testing was performed, and video inspections of more than 40 miles of the piping system were conducted. Historical water and wastewater records, rainfall records, and groundwater quality data were reviewed to evaluate system flow conditions in response to various precipitation condi-tions. The results of the study were also used to develop re-habilitation plans for the system. The 5-year plan rec-ommends that 10 percent of the sewer system man-holes, pipes, and pump stations be inspected on an annual basis. The results of the annual inspection will be used to identify the largest I&I contributors and prioritize maintenance activities and repairs for both the Industrial Wastewater Collection System (IWCS) and Sanitary Sewer Collection System (SSCS) com-ponents. The results of the annual inspections will also be used for long-range infrastructure planning to estimate future capital costs and present economic justification for corrective actions. To assist with long-range planning, a hydraulic model was devel-oped to help predict the impact of future develop-ment. The model evaluates the capacity of the IWCS and SSCS under normal operating conditions and the impacts to the systems that occur during various rain-fall events. The Base’s ongoing efforts to inspect, maintain, and repair the system will help ensure the sustainment of the basewide sewer system well into the future.
