IRP Update
Keeping the Community Informed and Involved
Robert Gill - IRP Program Manager

Welcome to the first issue of the Installation Restoration Program’s (IRP) Cleanup Report. An important goal of the IRP, in conjunction with the U.S. Environmental Protection Agency (EPA) and the Massachusetts Department of Environmental Protection (DEP), has been to involve the community in the cleanup process. This newsletter is just another way to share information about the cleanup program.

The cleanup program has reached a significant point in its operation. Groundwater treatment systems are currently pumping over 12 million gallons of water a day, cleaning it, and returning it to the aquifer. Six additional treatment systems are scheduled to be online by 2003. In this issue, we will highlight four of the treatment systems we have up and running. Look for profiles on other systems in future issues.

We hope that you find this newsletter informative. More information can be found at our website, www.mmr.org or by calling the IRP Community Involvement office at 508-968-4678, ext. 2.

 Performance Update
Treatment Systems Up and Running

Construction efforts dominated much of 1999 for the IRP. Twelve treatment systems are now in operation, a treatment system overview can be found on page 2. Some highlights of systems started in 1999 and 2000:

Chemical Spill-10 (CS-10) Treatment Systems
Four distinct extraction, treatment, and reinjection (ETR) systems are being used to clean up the CS-10 groundwater plume. CS-10 Sandwich Road treatment system went into operation on May 18, 1999, and is expected to be in operation for 30 years.

The CS-10 In-Plume treatment system began operation on June 24, 1999 and treats contaminated groundwater located in the central portion of the plume. The third system will clean up the south and southwest areas of the CS-10 plume. The enforceable milestone was met when this system began operation on April 27, 2000.

The fourth system began operation on January 31, 2000. This one extraction well system pumps groundwater from the CS-10 Plume under Hoophole Road in Mashpee. It is expected to be in operation for approximately nine years.

Storm Drain-5 South (SD-5S) Plume
The two wells in the SD-5S treatment system began operation on June 17, 1999. Each well removes volatile organic compound (VOC) from contaminated groundwater using recirculating wells. They are designed to each treat 60 gallons per minute.

Ashumet Valley
On November 22, 1999, the treatment system began to remove contaminants from the central portion of the Ashumet Valley groundwater plume. This system extracts the contaminants from the Ashumet Valley groundwater plume through three extraction wells operating at a combined pumping rate of 1200 gallons per minute. As with all ETR systems at MMR, the contaminated water is cleaned as it passes through granular activated carbon, and is then discharged to shallow infiltration galleries. The system is anticipated to be operational for a period of approximately 10 years.

Landfill-1 (LF-1)
The Landfill-1 (LF-1) treatment system began operation on August 26, 1999. The system is located on the western edge of the base and removes contaminants from the LF-1 groundwater plume. The LF-1 ETR treatment system is designed to clean 700 gallons of groundwater per minute.

In the next issue of the IRP Cleanup Report, look for highlights on the Chemical Spill-4 (CS-4), Fuel Spill-12 (FS-12), Fuel Spill-28 (FS-28), Fuel Spill-1 (FS-1) and Storm Drain-5 North (SD-5N) groundwater treatment systems.

Performance of Groundwater Treatment Systems
Presently there are 12 separate groundwater treatment systems in operation. The following chart gives an overview of how those systems are performing.  Through August 2000

*To date ** No data ppb = parts per billion

The Federal and State safe drinking water standards or maximum contaminant levels (MCLs) are:

The MCLs represent the maximum contaminant concentration of a given contaminant allowed in drinking water under state and federal regulations. For more information on MCLs, vist the EPA web site at http://www.epa.gov/safewater/mcl.html or the MassDEP web site at http://www.state.ma.us/dep/ors/files/sp00dw.htm.

How to get More information

There are several ways to obtain copies of information regarding the Installation Restoration Program.

Public Information Repositories/IRP Web Site
The Public Information Repositories allow the public access to the following information:

• Brochures, fact sheets, and other general information
• Maps of the sites and groundwater plumes
• Meeting summaries
• News releases
• Reports

Administrative Record On-line at www.mmr.org
Allows the public to search and view the following documents:

• Preliminary Assessment and Site Investigation reports
• Remedial Investigation and Feasibility Study reports
• Technical studies (e.g., a groundwater study)
• Records of Decision/Decision Documents
• Engineering design and construction information

E-mail requests to www.mmr.org
Hundreds of documents, reports, news releases, fact sheets, meeting agendas, and summaries are placed on the web site each year. If you cannot locate a document, you can e-mail your request by clicking on the "Contact Us" button on the home page, then type in and submit the information requested.

Web site gets facelift
WWW.MMR.ORG

As of May 22, 2000, the IRP web site was redesigned, reorganized and re-launched with a new look. The new site is intended to be a "one-stop" information and resource center for the IRP. Some of the changes include:

New Look
The site’s look was redesigned to reflect the work being done on and around MMR. It includes more photos of the work being done as well as interactive maps to help navigate between the different plumes and sites.

Reorganization
In addition to the change in the look of the site, there has been a reorganization to help make the navigation of the site easier and more streamlined. An inventory of the site content was taken, and out-of-date information was archived while current topics were organized to make information more accessible to the user.

Administrative Record Online
One of the most significant changes to mmr.org is that the IRP’s complete Administrative Record (AR) can now be found online. The AR contains all information used to select a cleanup remedy for a particular Superfund site. The site now has the added capability of searching the entire AR database.

We welcome your feedback on the new site at mmr@capetechsupport.com
